Getting the right setting on your humidifier can make all the difference in the world on your Luna G3. An improper humidity setting can cause significant dryness if dialed in too low. If adjusted too high, it can cause massive amounts of condensation in your CPAP tube. In either case, adjusting the humidity setting properly makes all the difference. Let’s take a look at how that adjustment is made.

Adjusting Luna G3 humidity with Standard Tubing

Adjusting the humidity setting is very easy on the Luna G3 CPAP. Especially when using standard “non-heated” CPAP tubing. Remember to increase the setting to add more humidity and decrease to reduce condensation. For the Heated Tubing instructions jump down to the next explanation.

Step By Step Instructions with Standard Tubing:

  1. Wake up the screen by pressing the knob button located to the right of the screen.
  2. Turn the knob right until you highlight the setting selection and press knob to access
  3. The very first adjustment will be the Humidity setting. Press knob again to access the setting. The number should turn yellow.
  4. Turn knob right to increase the humidity setting and left to decrease. It can go as high as 5 if you are dried out or as low as 0 if you have excess condensation. NOTE: If you turn all the way to the right, you can set it to auto and allow the Luna G3 to adjust itself based on your ambient room conditions.
  5. Press the knob to lock in your setting change.
  6. Press the home button below the screen until you are returned to your main home screen.

Adjusting Luna G3 Humidification setting with Heated Tube:

Adding in the Luna G3 Heated tubing can also make a big difference. If you are having serious dryness or serious condensation issues that you haven’t been able to resolve with the instructions above, then heated tubing may be a big help. Once you attach the heated tubing to the Luna G3 you have another setting to control. Let’s go over the step-by-step instructions.

Step by Step Instructions with Heated Tubing:

  1. Wake up the screen by pressing the knob button located to the right of the screen.
  2. Turn the knob right until you highlight the setting selection and press knob to access
  3. Now you will see that the first two settings are the Humidifier Setting and Heated Tube Settings. Press knob to highlight the setting and adjust from 0-5 or set as Auto. Increase setting to provide more humidity and decrease to reduce humidity and condensation. Note: If the Humidity setting is set to Auto, then the Tube setting will be changed to Auto as well. Auto setting is a great place to start.
  4. Press the knob to confirm your setting change
  5. Press the Home icon button located below the screen to exit back to the main screen.

How does the Auto Humidification feature work on the Luna G3

The Luna G3 CPAP and BPAP have an integrated thermometer and hydrometer. This gives the unit great insight to your room’s ambient conditions. The G3 will adjust the Humidity as well as the Heated Tube setting (if you have a heated tube) to provide you the appropriate amount of humidity without causing rainout. The Auto Setting is a great place to start when you are adjusting the humidity settings on your G3.

For a lot of CPAP users, their usage time on their compliance report is a big deal. This may be because their insurance company requires a minimum compliance percentage. Some other CPAP users are required to be “compliant” for their job. In any case, missing time on the report is a problem. So, what is going on? There are a couple things that can cause this issue. Let’s dive in a little deeper.

Why doesn’t all of my usage show on my CPAP Report?

There are three main issues that we see on this issue. All of them can be major issues if you have to meet a minimum usage requirement on your Compliance Report. For more information about CPAP Compliance, as well as tips and tricks for improving your compliance check out our CPAP Compliance Blog here. Let’s take a look at those three main issues to see if you have an easy resolution.

Major CPAP Mask Leaks:

The CPAP is designed to only include good usage data on the Compliance Report. This is to prevent bad Therapy Data as well as cheating. If there is a major mask leak your CPAP will throw out that data. Meaning, that it will not be included on your CPAP Compliance Report. The main solution here is to remedy the leak. We have a great blog on stopping CPAP Mask Leaks here.

The Day Resets During your Usage:

For most CPAP machines, the day resets at noon. This is because most people sleep at night. However, many of our CPAP customers work at night and sleep during the day. This can cause part of your CPAP usage to go on two separate days. This will dramatically throw off the time you think you are going to see on your CPAP report. The easiest resolution for this is to contact your provider to have the day cutoff changed for you. Rest assured that the time will be counted, but it may be on two separate days.

Trying to Cheat the System:

If you aren’t wearing the CPAP and breathing on it, then the time doesn’t count. We have had so many customers attempt to cheat the system by putting the mask under a pillow or just running it without wearing it. This never works. The CPAP must see inhalation and exhalation to count the usage of the CPAP. There are ways to trick it, but they are pretty complicated, and will not serve any long-term purpose.

What does everything Else on the CPAP Report Mean?

Obviously, the Compliance percentage is the first obvious metric on your CPAP Report, there is a lot more. There are statistics like: Mask Leak, Apnea Hypopnea Index, Central Apnea Index and much more. For a great tutorial on that you should take a minute to read through our Blog on understanding your CPAP Report here. It is always a great idea to meet regularly with your Sleep Physician to make sure that your therapy is headed in the right direction.

For almost as long as CPAPs have existed “Ramp” has been a standard setting included with most CPAPs. But what does it do? In this blog we will help you understand what the Ramp feature does, when you should use it, when you shouldn’t use it, how to adjust it, and things you should keep in mind. So, let’s dive in.

What is the Ramp Setting on my CPAP?

Ramp is almost always a timed setting on your patient settings menu. That setting will be the amount of time it takes for your CPAP to increase from a “Starting Pressure” to your “Therapy Pressure”. Both the starting pressure and therapy pressure are usually located in the Clinical Setting menu of your CPAP. For instance, let’s look at a Starting Pressure of 6cm, a Therapy Pressure of 12cm with a ramp of 30 minutes. In this case when you start your CPAP, and your ramp is engaged you will begin with 6cm of pressure and the CPAP will gradually “Ramp” up to 12 cm over a 30-minute period.

When Should I use Ramp on my CPAP?

Ramp is a great feature for a myriad of CPAP users. That is why it is a standard feature. Keep in mind that Ramp is a comfort feature. So, using it, or not using it, is completely up to you. Once your Ramp time is complete the CPAP will be at your Prescribed Therapy Setting. Let’s look at some great uses of Ramp for certain CPAP users.
  • New CPAP Users– New CPAP users really like the Ramp feature. It allows a first-time CPAP user to acclimate at the lower Starting Pressure and fall asleep much easier.
  • Waking up in the middle of the night– When you wake up in the middle of the night falling back asleep at Therapy Pressure can be tough. Using the Ramp to lower the pressure for a while is very helpful.
  • High Pressure CPAP Users– If you are a CPAP user with a higher pressure, then Ramp can be very beneficial. The hope is that you will fall asleep before encountering the full Therapy Pressure of your CPAP.

When Ramp is a bad idea on your CPAP?

Keeping in mind that Ramp is a comfort feature, you should know that at times it can be a hindrance to your CPAP experience. If the Ramp is making you less comfortable, then you should consider going without it. Let’s look at some instances where Ramp may not be the best choice.
  • Old School CPAP users– For people that are upgrading an older CPAP Ramp may be a surprise setting for you. Many long-term CPAP users are accustomed to their Therapy Pressure. They need to feel that full pressure to fall asleep.
  • People that fall asleep fast– If you fall asleep when your head hits the pillow, then we all need to know your secret ;). For those users the lower Starting Pressure may not be enough to keep your airways open, and you may have apnea while the CPAP is ramping up. In those cases, reducing the Ramp time may be a good option.
  • CPAP users with severe apnea– This is another time where the lower starting pressure during the Ramp may not be enough to keep your airways open. You can increase Starting Pressure or reduce Ramp Time to help with this.

How to Adjust your Ramp Setting:

Adjusting your Ramp setting is fairly simple. However, you should keep in mind that the Ramp also has a lot to do with Starting Pressure. Starting Pressure on most CPAPs is located in the Clinical Settings Menu and has to be changed by your provider or doctor. The Ramp Setting is usually located in the Patient Menu. When you select this setting, you can increase the time to have a longer Ramp or decrease the time to get to your Therapy Setting quicker. For some newer CPAP models, you may even be able to set your Ramp to an “Auto” setting. In the Auto Ramp setting the CPAP will monitor your breathing and increase the pressure when your breathing slows to a sleep pattern.

Things to keep in mind with your Ramp Setting:

As you acclimate to CPAP your Ramp setting may be a very valuable tool to increase your comfort. That is, if you keep a few things in mind. Let’s go over a few pointers:
  • Adjust in small increments– As with all CPAP settings, a gradual adjustment is best. Going too far in one direction or another can create issues as well.
  • Ramp has two settings– While in your Patient Level Menu you may only see Ramp Time, it is important to remember that you can also adjust your Starting Pressure. You will have to loop in your CPAP Provider or your Physician, but it is another option to keep in mind.
  • If it ain’t broke, Dont fix it– If you aren’t having an issue with pressure or falling asleep on CPAP, then it may be best to leave the settings alone.

There are few side effects to using CPAP and going bald probably isn’t the first one that you thought about. However, it is something that we have had mentioned as a concern from our customers over the years. Obviously, nobody wants to lose the hair that they have. So, let’s take a deeper look why it happens and how to fix it.

What Causes Hair Loss on CPAP?

No, the CPAP Machine is not making you bald. The issues that we have heard regarding loss of hair on CPAP have all centered around headgear and frames on the CPAP mask itself. In most cases it centers around the masks that have silicone frames or straps that rub against the hair on your head. The silicone is tacky and as you move at night it pulls the hair out of your head. There are a couple options to help.

Options to Eliminate the Hair Loss on CPAP:

The main thing that you have to do is to get a barrier between your hair and the silicone parts of the mask. Below are a couple options that may give you some relief.
  1. One of the options would be a generic mask frame wrap. Many CPAP masks come with a frame wrap of some sort, because they know this is an issue. One of those would be the DreamWear. You simply wrap the velour wrap around the frame and Velcro it in place. This provides a smooth surface for the frame or headgear to move as you move. Without the pull.
  2. You can also try out a hair cap. These are obviously a bit more involved, but they do work. You can find them at almost any hair shop or Walmart. Simply put the head cap on before bed and then fit your CPAP mask over top of the cap. This will give you a comfortable mask fit without any pull on your hair what-so-ever.

Which CPAP Mask Cause Hair Loss

Most CPAP masks are designed to be as comfortable and effective as possible. The balance of comfort and effectiveness is the most difficult part of making CPAP masks. And because everyone has different preferences and features there are a ton of different style out there to choose from. Most of them feature fabric headgear that moves gently around the head without pulling or abrasion, while others have silicone frames that surround the head. The ones like the DreamWear cradle or the N30i have awesome features but may cause pulling of the hair. This is because the frame that delivers the air from the top of your head to the nose is silicone. For other CPAP users even the fabric headgear can pull hair. Using one of the Mask Frame Wraps can allow use of these CPAP mask options without the pulling of your hair.

Over the years we have had a TON of CPAP users that run out of water during the night, and until now we didn’t have much of an option. After reading that feedback for the 1000th time, it hit me that there is an option. In this blog we are going to take you through the process of how to add extra humidity without running out of water in the middle of the night.

How does the humidifier on the CPAP work?

The first thing that you have to understand is how the humidifier works. Your CPAP most likely has an integrated heated humidifier system. This means that you are adding water to a tank nightly and the CPAP uses that water to humidify the air you are breathing. Most humidifier chambers are about 300 ml, which is not a lot of water. The chamber has a metal plate on the bottom that is heated, allowing more of the water to evaporate into the air passing through the CPAP to you. The higher you heat the water the more water evaporates into the air you are breathing.

Why is the CPAP running out of water?

So now that you understand how it works let’s discuss why it runs out. Because you only have so much water available in the water chamber you will only have so much time available with humidity. Most CPAP water chambers will allow for at least 8 hours of usage. However, if you have conditions where the air in your home is dry then it may absorb a lot more water from the CPAP as it passes through the humidifier. This means that what was meant to last 8 hours, may only last 4 or 5. Then you wake up dry as the Sahara Desert with an empty tank. Time to offer a real solution.


How can I fix the limited water issue on my CPAP?

Unless you enjoy waking up in the middle of the night to add water to you CPAP, then you probably need a solution. Finally, we have an option for you. We have used the HC-150 external humidifier for years with Ventilators and older style CPAPs. Now, we are using it as an addition to your CPAP to add extra water volume and humidity. The HC-150 holds an additional 400ml (13.5oz) of water. This will at least double your water capacity. Now, let’s learn how to use it properly.

How to use the HC-150 External Humidifier Properly:

Setting up the HC-150 is pretty simple. There are things to keep in mind to make sure that it is running properly. The first thing is to make sure that you have the short adapter tube running from the back of the CPAP into the top of the HC-150 humidifier. Then you will connect your longer CPAP tube to the outlet of the HC-150 and to your mask. It is best to use the smaller adapter hose from the CPAP to the HC-150 to avoid pressure loss.

How to Adjust the Settings when using the HC-150 on CPAP:

This is where the rubber meets the road. You have to be careful to make sure that you don’t add too much humidity and cause “rainout”. The best way to do this is by adjusting up slowly on a night-by-night basis. To start with we recommend turning the integrated humidifier on the CPAP off and leaving that water tank empty. Start with the HC-150 alone to see if it will be enough. Start the HC-150 setting at a little over 2 on the front dial. Then turn it up nightly as needed to keep from drying out. If you max out the HC-150, and still cannot get enough humidity, then you can add water to the CPAP and gradually increase the humidifier setting on the CPAP to add in even more humidity. It may also be smart to add in a tubing insulator like one of our tube wraps to help reduce the chance of “rainout” condensation in your CPAP tube.

Things to keep in mind when setting up the HC-150 this way:

There are a few things that you should be aware of when setting up an external humidifier like the HC-150 on your CPAP machine. Let’s dive in a little deeper on that front:
  • Don’t go overboard to begin with– Work the settings up slowly. If you add too much humidity up front, then you may end up blowing water in your face because of “rainout” condensation.
  • Stick with our recommended tubing setup– You don’t want to add in too much tubing length, because it can affect pressure.
  • Start with the HC-150 alone– You may find that the HC-150 does a great job of keeping you humidified without having to add in water to the CPAP chamber at all. You can always add that in if the HC-150 isn’t enough.
  • Heater plate it HOT– Be careful not to touch or let anyone else touch the heater plate. It can be really hot.
  • Remember to turn it off– It has a manual on/off button. Make sure you turn it off in the morning after you turn the CPAP off.
  • Best to keep it lower than yourself– In case there is excess condensation in the tubing, the water will drain back into the HC-150 chamber instead of in your face. They recommend keeping it on the floor which seems silly but keep this in mind.
  • You can’t use heated tubing– If you are currently using heated tubing on your CPAP then you will have to switch to standard tubing. You can add in a tubing snuggie to help insulate the tubing and prevent rainout.

What else can the HC-150 humidifier do for me?

  • Use with Travel CPAP– The HC-150 external humidifier may also be a good fit for people wanting to use a Travel CPAP. Almost all travel CPAPs do not have humidifier, so it may be a good add on to that setup.
  • Sub it in for a broken CPAP humidifier– From time to time the integrated CPAP humidifier may fail. If money is short or you can’t get a new CPAP, then the HC-150 may be a good use.
  • Double down on humidity– Some CPAP user just don’t get enough humidity from their CPAP humidifier. In that case you can add the HC-150 in to double the humidity output. Be careful not to add too much in this case.

HC-150 Accessories:

Maintaining your HC-150 CPAP Humidifier:

  1. Switch off the HC-150 and unplug from the power cord
  2. Detach the water tank and allow it to cool.
  3. Wipe the HC-150 exterior with a damp cloth and mild dishwasher detergent. Note: do not use harsh abrasives or solvents, as these may cause damage.
  4. Daily- Rinse the water chamber and breathing tube with warm soapy water. Rinse well and allow to air dry.
  5. Weekly- Soak the inside of the chamber for 10 minutes in a 1 part white vinegar 2 part water solution. Rinse thoroughly and air dry before use.

Philips Respironics has issued an Urgent Medical Device Correction on a handful of their Nasal and Full-Face CPAP Masks. All of these CPAP masks have magnets on the headgear straps. These magnets are designed to help you attach and detach your headgear more easily. However, they can cause issues for certain CPAP users. Let’s dive into the details of what this might mean for you below. You can read through the formal notification on the Philips website by clicking here. Click on any of the words in blue to see details on the items in blue.

What Implants and Devices are affected by these CPAP Mask Magnets?

Contraindication: Use of the mask is contraindicated for patients and their household members, caregivers, and bed partners that may be in close vicinity to patients using the masks, that have implanted devices that may be affected by magnets, including but not limited to:
  • Pacemakers
  • Implantable cardioverter defibrillators (ICD)
  • Neurostimulators
  • Magnetic metallic implants/electrodes/valves placed in upper limbs, torso, or higher (i.e. neck and head)
  • CSF (cerebral spinal fluid) shunts (e.g., VP (ventriculo peritoneal) shunt)
  • Aneurysm clips
  • Embolic coils
  • Intracranial aneurysm intravascular flow disruption devices
  • Metallic cranial plates, screws, burr hole covers, and bone substitute devices
  • Metallic splinters in the eye
  • Ocular implants (e.g., glaucoma implants, retinal implants)
  • Certain contact lenses with metal
  • Implants to restore hearing or balance that have an implanted magnet (such as cochlear implants, implanted bone
  • conduction hearing devices, and auditory brainstem implants)
  • Magnetic denture attachments
  • Metallic gastrointestinal clips
  • Metallic stents (e.g., aneurysm, coronary, tracheobronchial, biliary)
  • Implantable ports and pumps (e.g., insulin pumps)
  • Hypoglossal Nerve Stimulators
  • Devices labeled as MR (magnetic resonance) unsafe
  • Magnetic metallic implants not labeled for MR or not evaluated for safety in a magnetic field

Which Philips Respironics Masks are affected?

There are 4 CPAP mask models that we have sold that are affected. They are the Amara View Full Face, DreamWear Full Face, DreamWisp Nasal, and the Wisp Nasal CPAP mask. All of these models feature magnets on the headgear straps that can be an issue for affected CPAP users. For most of these models there is not resolution, and you would need to change mask models. For one however, there is a quick and easy resolutions. Below we go over the individual affected masks and appropriate models that would be similar if you need to make a change.

What do I do if I am affected by the Magnets on the CPAP mask?

All 4 of these masks affected by the Urgent Medical Device Correction have either a comparable alternative that we can recommend or might even be able to be resolved with a quick alternative clip. Let’s look at each of the masks individually to see what might be best for you.

DreamWear Full Face

The DreamWear full face is a Minimal contact full face CPAP mask. It features magnetic clips that are built into the cushion of the mask. For this mask there is no resolution that will allow you to continue use of the DreamWear Full. This means that you would need to seek out an alternative. Unfortunately, the only direct competitor to this mask would be the F30i from ResMed, but it also has magnets. So, your best bet would most likely be the Evora Full Face by fisher and paykel. It has a similar fit with a fairly low profile, but it does have a front tube attachment.

Amara View Full Face

For the Amara View there is a pretty nice and easy way to continue use of this mask without magnets. The only thing necessary is to purchase the older style manual clips for the Amara View. These clips allow you to manually clip the headgear into place without the magnets being attached at all. To view these manual clips, click here. If you would like to change models entirely, then the Evora Full Face would again be your best bet.

DreamWisp Nasal Mask

The DreamWisp is a tough one to resolve. This is because it is the only Nasal CPAP mask that has an over the head tube connection. Because of that you will have to sacrifice something in the change. You can convert to a standard Nasal CPAP mask without magnets like the Eson 2 or Mirage Fx. This allows you to keep the standard “over-the-nose” nasal fit. If you would like to keep the top-of-head tube connection you would move to a nasal cradle design like the Evora Nasal, DreamWear Nasal or the N30i.

Wisp Nasal Mask

The Wisp Nasal Mask is another tough one to replace. That is because the headgear and frame are pretty unique. There is no frame in front of the nose which gives you a nice clear line of sight while wearing the Wisp. Masks like N20 and the N10 which would be very similar to the Wisp also have magnets. So, in this case again you would have to go to a more standard style Nasal Mask with a traditional frame like the Eson 2 or Mirage FX to achieve the traditional nasal fit. You can also consider a Nasal Pillow mask or Nasal Cradle mask to achieve the open line of sight.

What does ResMed say about their Mask Magnets?

I reached out to my representative at ResMed to see where they stand on the Mask Magnet issue. Since ResMed has quite a few CPAP masks that feature really nice magnets, I was concerned. Please keep in mind that this is the response on the day that this blog was written. If this response changes, then I will do my best to update this information. I will also clarify that despite the word “recall” below, I have not heard the word “recall” from Philips or anyone else so far.

ResMed’s Response:

“We are aware of the September 6, 2022, recall of certain Philips masks due to a safety issue with magnets that may affect some medical devices in or on a patient.  ResMed is carefully reviewing the issues outlined in the FDA’s recall report, as we do with any relevant regulatory activity in the market. We believe our (ResMed) masks are safe to use.  While some ResMed masks use magnets in the lower headgear straps and the frame to assist with ease of closure and a secure fit, these masks contain magnets designed to a strength below the guidance from the International Commission of Non-Ionizing Radiation Protection (ICNIRP) for use of magnets in this setting, and ResMed masks provide instructions to users about the use of magnets in proximity to other medical devices.  We will consider whether additional work is needed to further demonstrate the continuing safety of our masks that use magnets. ResMed continually evaluates our products against applicable regulatory standards, industry guidance, safety standards, and good clinical practice, as they develop.”

Almost all of the home CPAP models come with a Heated Humidifier. Most of these are actually integrated with the CPAP machine itself. This means that no matter whether you are using the water or not, the humidifier system is there. So, you may be asking, “do I need to add water to your CPAP” or “can you leave the CPAP water chamber empty”. More than likely that is because you are trying to avoid the hassle of filling and maintaining the water chamber. Let’s take a look at whether that is a good idea for you as well as things to consider.

Signs that you might can do without the water:

Deciding to use the CPAP with an empty water tank is most likely something you are considering making your life simpler. That is completely understandable. Here are some signs that it may be a good option for you.
  • You have never experienced dryness while using your CPAP.
  • The water tank always seems to be full in the morning and you aren’t dry.
  • You live in a humid environment.
  • You travel frequently and cannot lug distilled water with you.

Signs that you should stick with your humidifier:

While dealing with a CPAP humidifier can be something you would like to cross off the “to do” list permanently, it is not the right option for everyone. Here are some reasons that you should stick with the humidifier system.
  • You are dried out frequently when you wake up.
  • You take medication that gives you dry mouth as a side-effect.
  • You live in a dry region.
  • Your CPAP frequently uses a good bit of the water in the tank overnight.

Important things to remember if you leave the water tank empty:

If you are going to operate the CPAP without water in the water chamber, there are some things to keep in mind that will help you. Let’s detail that below.
  • Make sure that you disable the humidifier. In most CPAPs that means turning your humidity setting in the patient menu down to zero.
  • Keep the tank in the machine unless you have purchased a bypass adapter and installed it.
  • Keep some distilled water close in case this doesn’t work out well.

The Luna G3 Auto CPAP is the latest from 3B medical. Our experience with 3B CPAPs has been very positive overall, and we expect the G3 Auto CPAP to be a similar experience. It is small, lightweight, and has all of the comfort features that today’s CPAP user would expect. Let’s take a deeper dive.

What is new on the Luna G3 Auto CPAP?

The previous 3B CPAP model was the Luna 2 and was a great CPAP for us and our customers over the years. However, that CPAP had its shortcomings. The two biggest downsides to the Luna 2 were the Size/Weight and the connectivity. These two things made it a tough choice for those that wanted a smaller/lightweight option with connectivity for reporting. The Luna G3 Auto CPAP completely resolves those issues. It takes up just 10.5″ x 5.7″ on the nightstand and weighs just 3.7 lbs. On top of that the Travel Case is just 13″ x 11″ x 5.5″. This means that finding a spot on the nightstand and traveling with your Luna G3 is a breeze. The G3 also features an integrated cell modem. This means that your compliance data will upload automatically. Giving your provider and doctor simple access for reporting your CPAP usage. Additionally, you can expect all the great things of the past like, quiet operation, durability, and comfortable operation.

Features of the Luna G3 Auto CPAP:

  • Small and lightweight– At just 3.75 pounds and a dimension of 4.49″ x 5.71″ x 10.43″ you will have no issues traveling with or finding a spot for your Luna G3.
  • Integrated heated tubing– The heated tubing on the G3 is a nice upgrade from previous 3B models. The heated tube plugs directly into the back allowing you a premium humidification experience.
  • Quiet Operation– Sound might be the most-asked question from the spouses of our customers. At just 26 dBA, the G3 is whisper quiet while operating at 10cm.
  • Multiple data options– The Luna G3 has the option of SD card, scan upload, or remote upload. It is great for truck drivers or those that need to keep close monitoring with their doctor.
  • Multiple Therapy Options– Whether you are using fixed pressure CPAP or need the Auto Adjusting settings, this CPAP can handle it comfortably for you.

Luna G3 Auto CPAP Pros and Cons:

This CPAP will be a great option for new CPAP users as well as those who have been on CPAP for years and need a modern upgrade. It has great upsides as well as a few downsides that you should take into consideration when checking out new CPAP options.

Luna G3 CPAP Pros:

  • Small and lightweight– This CPAP is obviously not a “Travel CPAP”, but for those that need a CPAP with all the features of a home CPAP, but also the ability to get on the road from time to time you have it here.
  • Connectivity– Previous 3B models did not have any connectivity integrated into the CPAP. The G3 changes that. It has an integrated cell modem that will automatically upload your data back to us and your doctor. This means that if you need reporting for your job or great communication to your doctor you are in luck.
  • Affordable– 3B came into the market with affordability in mind. They have consistently offered good products at competitive pricing. They hit that out of the park on the G3 CPAP.

Luna G3 CPAP Cons:

  • Water chamber can be tricky– Removing the water chamber for cleaning and maintenance can be tough. You have to press down firmly to release it, but it can be tough for people that have dexterity issues. Luckily, the water chamber can be filled without removing it.
  • App isn’t very good– As of writing this today the app is not great. That can, and probably will change with time. As for today, if you are a person that likes good “tech”, the app will not live up to your standards, most likely.

Our thoughts on the Luna G3 Auto CPAP:

Our overall opinion on the Luna G3 Auto CPAP is positive. While the Luna 2 had some limitations that forced us to limit our recommendation to certain CPAP users, the Luna G3 has changed that. If you are a basic CPAP user, then this is a great option for you. The only person that we would not recommend this to would be someone that might have issues removing the water tank (most people will not) or CPAP users that love their reports on their app every day. That means for almost everyone looking for a great and affordable CPAP option, the Luna G3 has to be on your short list of considerations.

Adjusting the Therapy Settings on the Luna 2 Auto CPAP is very simple. It is, however, very important to consult with your Sleep Physician about settings changes in advance of making setting changes. There are also comfort settings that may dramatically improve your therapy on the Luna 2 CPAP. So, let’s dive in to the “how-to” details:

Step 1:

From the Main Interface, press and hold the Dial and Ramp Button for five seconds. The screen displays the Initial Setup Interface of the Maintenance Menu, as shown in Fig.1-3. The first icon on the left side of the screen indicates the Main Interface, the second Icon with the cog icon indicates the Clinical Menu, and the third icon indicates the Service Menu. Press the knob to enter the menu.

Step 2:

As you turn the Dial clockwise, the cursor moves downwards from one option to another. As you turn it counterclockwise, the cursor moves upwards. When the cursor is on a certain option, press the Dial , and the option is then displayed in yellow, meaning that the option can now be adjusted. Once you adjust to the setting desired, Click the knob once more to confirm the change and mode on.  Now let’s look at each setting in detail.
You will now see the settings menu. Mode will be your first option. Press the knob to select the mode. It can be set as CPAP or Auto. In CPAP mode you will be in a fixed CPAP pressure. In “Auto” you will be in an auto-adjusting mode, and the CPAP will adjust to the best pressure for you within the range set later on.
Treat P:
This setting will only be displayed if you have selected the CPAP mode in the setting above. Treat P is the treatment pressure. It can be set from 4 cm of pressure to 20cm of pressure.
This setting will display if you have Selected “Auto” therapy mode in the first setting. This setting will be the most minimal pressure in the pressure range.
Max Ramp:
The max ramp is the longest amount of time available for your ramp duration. The ramp setting can be changed in the patient level menu, but the “Max Ramp” setting in this clinical menu will put a cap on how long the patient menu ramp can go.
Ramp P:
This setting is the starting ramp pressure. It is the pressure setting that the CPAP will go to when the patient presses the ramp button during therapy.
This setting will only display if you have selected “Auto” mode in the first step. The Max APAP is the maximum amount of pressure that the Luna 2 will go to during Auto CPAP therapy. It can go as high as 20cm of pressure.
Auto On:
This feature can be turned On or Off. If it is turned “On” then the Luna 2 will turn on as soon as it senses your breath when. Bypassing the need to manually turn your CPAP on after attaching your mask. If it is “Off” then you will have to manually turn on your CPAP.
Auto Off:
This feature can also be turned On or Off. When turned “On” the Luna 2 will shut itself down when you take the mask off. When turned “Off” you will need to manually shut your CPAP down when you take your mask off. You may want to turn this feature off if you have noticed the Luna 2 shutting down during therapy. This can sometimes be due to high leaks and the CPAP thinking that you have taken the mask off.
Leak Alert:
This feature can also be turned “On” or “Off”. When it is turned off the Luna 2 will alert you to high leaks in an effort to wake you up for mask adjustments. If you leave the feature “Off” then you will not be alerted to high leaks during therapy. You will still be able to see leaks on the therapy report regardless of what setting you choose here.
The Exhalation Relief feature on the Luna 2 CPAP is called Reslex. It is similar to EPR in ResMed models and Flex in Philips Respironics models. It can be adjusted from 0-3. the higher you go on that setting the more exhalation relief you will have. For instance. If your Luna 2 is set on a Therapy Pressure 10cm and your Reslex setting is 3, then you will inhale at 10cm of pressure and exhale at a pressure of 7cm. The math looks like: 10cm-3cm=7cm. If you have the same Therapy pressure of 10cm and a Reslex of 1 then you would inhale at a setting of 10cm and exhale at a pressure of 9cm.

Step 3:

Now that your Therapy Setting are adjusted in the Luna 2 CPAP, you will scroll all the way to the bottom and select “Home”. This will take you back to the operational menu where normal therapy can be performed.
