CPAP product reviews and other helpful tips for CPAP users!

If you’re researching or shopping for a new CPAP machine, chances are you are either new to CPAP therapy or you’re replacing the one you already have. We’ve said this many times before, CPAP machines these days are packed with incredible technology. But what exactly is this technology? 

CPAP machines have integrated wireless and battery-powered options, Bluetooth capabilities, remote monitoring and reports at your fingertips through apps on your phone. Another technology which we will be focusing on is a technology called Expiratory Pressure Relief (EPR) or FLEX which are both features to increase comfort and compliance for all users. 

What exactly is EPR or FLEX? Continue reading as we break down some fancy acronyms and abbreviations. Learn what EPR means and the difference between the types of Flex available as we simplify the terms much as we can. Here we go!

What Is Expiratory Pressure Relief (EPR)?

CPAP machines have “comfortable” settings that allow CPAP therapy to mimic your natural breathing pattern as much as possible. ResMed calls this feature EPR while Philips Respironics calls this comfort feature, Flex.

ResMed defines their comfort setting as EPR - Expiratory Pressure Relief. In other words, making it easier for you to exhale or providing a deeper exhale with each breath while on CPAP therapy. For example, your CPAP pressure setting is 10cmH20 with function EPR 3 on...you would be inhaling at 10chH20 and exhaling at a dropped pressure of 7cmH20 and will return to 10cmH20 on the inhale.

There are 4 settings for Expiratory Pressure Relief on a ResMed machine: OFF, Setting 1 = mild comfort (1 cm H20), Setting 2 = medium comfort (2 cm H20), Setting 3 = maximum comfort (3 cm H20).

What Is Flex Technology? 

Philip Respironics calls their comfort setting Flex. Flex comfort feature provides users with pressure relief on various (CPAP, APAP or BiPAP) modes of therapy. There are various types of Flex available. C-Flex, A-Flex, Bi-Flex and C-Flex+.

C-Flex Pressure: Breakdown

C-Flex, identical to EPR on ResMed, lowers pressure during exhalation for users to adjust to CPAP therapy and works on a breath-by-breath basis.  Using the same example from earlier, if your CPAP pressure setting is 10cmH20 with function EPR 3 on...then, you would be inhaling at 10cmH20 and exhaling at a dropped pressure of 7cmH20 and will return to 10cmH20 on the inhale.

C-Flex also has 4 settings for on their machines: OFF, Setting 1 = mild comfort (1 cm H20), Setting 2 = medium comfort (2 cm H20), Setting 3 = maximum comfort (3 cm H20)

Following along so far? Good, let’s keep going.

Bi-Flex Pressure: Breakdown

Bi-Flex works on BiPAP mode and offers pressure relief at both inhalation and exhalation. The Bi-flex setting offers pressure relief at 3 important areas - the transition from exhalation to inhalation, the transition from inhalation to exhalation and during the exhalation.

A-Flex Pressure: Breakdown 

A-Flex works within Auto-CPAP mode. Like C-Flex, A-Flex provides pressure relief at the beginning of exhalation and like Bi-Flex softens transition avoiding spike ups from inhalation to exhalation. It's a smoother and more comfortable feeling. A-Flex mimics your natural breath the most.

C-Flex+ (Plus) Pressure: Breakdown

C-Flex+ (Plus) is a newer setting within the more advanced CPAP machines when in fixed-CPAP mode.  Like C-Flex, C-Flex+ provides pressure relief at the beginning of exhalation. Like A-Flex, C-Flex+ offers a smoother and softer transitioning from inhalation to exhalation providing additional comfort when in fixed-CPAP mode.

If you got a blank stare and feeling a bit confused, we don’t blame you - it can be confusing. The take-home message is Expiratory Pressure Relief (EPR) and Flex are both comfort settings available on ResMed and Respironics machines. They come in different modes to ultimately make your adjustment to Sleep Apnea therapy more comfortable by mirroring your most natural breathing patterns possible regardless of your CPAP pressure.

Which Comfort Function Is Best For You And Your CPAP Machine?

Which function is best for you? Ultimately, it comes down to personal comfort and preference. You’ll need to give the functions at various settings a test drive. Some people like EPR and Flex, some don’t use them and others even dislike these comfort settings. These settings may bring on other problems - possibly make your apnea better or worse or the pressure changes may increase your chances of experiencing CPAP mask leaks.

After all, that’s said, many do find the comfort functions helpful. This is the part where we say try it, see what setting works best for you!

There is a stigma when people think of full face CPAP masks. Many think they're ugly, bulky, intrusive and the thought of wearing one to bed sounds impossible. However, full face masks are the Holy Grail for many CPAP users; they are designed with specific features and benefits that have made them a go-to mask for millions in the CPAP community. 

How Does A Full Face Mask Differ From Other CPAP Masks?

So, what makes a full face CPAP mask different than the others? A full-face mask covers the nose and the mouth -  like an oxygen mask you might see a fighter pilot wear, but nicer - with straps that are worn over the head with headgear holding it in place. It sounds uncomfortable, but they've made them pretty form-fitting and soft now.

By highlighting the pros of full face masks and giving it a well-deserved spotlight, we hope to break the stigma of how the general public feels about this often demonized and incredibly well-designed CPAP mask.

Advantages Of A Full Face Mask For CPAP Therapy

Below is a list of the top advantages that we feel CPAP users will receive by choosing a full face CPAP mask over other styles. 

1) It's stable & secure: Full face masks tend to be a bit larger, heavier and have more material (straps and thicker headgear) than, say, a nasal pillow style mask. These CPAP  masks cover more of the face which results in better pressure when compared to their nasal or nasal pillow style counterparts. It is an excellent choice for restless or back sleepers - the straps tighten well and offer support to keep their masks in place in different positions at night. 

2) Mouth breathers or nasal obstructions: Full face-style masks are an excellent choice for natural mouth breathers or those who suffer from nasal obstruction or congestion. This style of a mask allows you to get the Sleep Apnea therapy you require either breathing through your mouth or nose. This is also a great style of mask for those who suffer from cold or flu symptoms. No need to lose good sleep, when your nose is stuffed and you need it the most. 

3) Tolerable with higher CPAP pressures: Full face CPAP masks cover more of the face, therefore allowing high pressures to be more tolerable by CPAP users.  The full face mask offers more surface area for the air to move around before entering the airways making the pressure less direct and more comfortable. These masks are beneficial for restless sleepers and popular with users who like to sleep on their backs. 

4) Facial hair:  Got a beard? This style of CPAP mask is popular with users who have facial hair, specifically those who sport a full mustache or a thicker beard. Facial hair can prevent a good seal because the cushion cannot grip the face properly, resulting in leaks and a frustrated user. The full-face style fits tightly around the nasal bridge and the chin providing a better air seal. 

While there are many notable benefits of a full face-style mask, it is not for everyone. All full face masks are not made equal and manufacturers use various materials that may work for one person and not the next. Remember to do your research, ask questions and try on a sample if possible.  Spend at least as much time trying on CPAP masks as you would buying a new pair of jeans!
