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!

ResMed's latest AirSense 10 Series is designed with a humidifier seamlessly integrated called HumidAir. The main unit comes with a standard water chamber, but there is an optional cleanable water tank available for purchase also. 

ResMed has been making 'standard' and 'cleanable' versions of water chambers for quite some time now. Their previous two CPAP models, S9 and S8 Series humidification in H5i and H4i came in both a standard and a cleanable version.

But which one is better? Do I need a cleanable tank? Or will the standard tub suffice? Continue reading to learn the difference between the two CPAP water chambers and to find out which one best suits your needs. 

Standard Water Tank: 

The standard water tank is the one that comes with the original machine purchase. This standard tub opens at the top and has a shell that is made with injection moulded plastic. The standard chamber’s base is made with aluminum and the cover is made with thermoplastic elastomer and is latex-free. The standard HumidAir is meant for single patient use and cannot be disinfected. This version requires hand washing with mild soap and water (it is not dishwasher or washing machine safe) and requires replacing every 6 months. 

Cleanable Water Tank: 

The cleanable water tub is considered an upgrade of the HumidAir water tub. Almost identical to the standard tub, the cleanable is designed to be easily taken apart to be cleaned and snapped back together easily. 

This HumidAir's shell is also made with injection-moulded plastic but provides even more durability than the standard tub. It has a stainless steel base and silicone to seal the water inside the chamber. Though a bit more expensive, this premium water tub has a life span of 2.5 years and is resilient enough for clinical use in hospitals or sleep clinics with various patients and can be disinfected time and time again.

Standard vs Cleanable: Which One Do You Need?

The short answer is the standard HumidAir performs just fine. But what you select depends on your lifestyle, cleaning routine and budget. Do you own a dishwasher? Do you mind paying more upfront for something that will last longer? Or save a few bucks and replace the parts every few months? Ultimately, both ResMed water tubs does the job and does it well. It comes down to personal preference in the material and price of the replacement parts.
