Essential CPAP Machine Features

The CPAP machine makes it possible for those with sleep apnea and other serious respiratory challenges to finally get a good night’s rest. There are some essential CPAP machine features that make the device more comfortable to use. This is your guide to what these pieces are and how they can work in your favor.

Exhalation Relief

Getting used to wearing a CPAP mask after receiving a sleep apnea diagnosis is not something that anyone looks forward to. The apparatus is often believed to be both clunky and uncomfortable. In addition, the thought of having to get used to continuous air pressure blown through your nose and mouth may be overwhelming in the beginning. That is why exhalation relief, also known as exhalation pressure relief, is available.

Exhalation relief was initially developed for bilevel CPAP machines designed for patients with more serious respiratory disorders. However, standard CPAP machines are also able to change the air pressure based on the patient’s breathing cycle. The end result is a more natural and comfortable breathing experience.

Memory Card

Most CPAP machines are able to record therapeutic data to help you and your doctor determine the effectiveness of your treatment. Recorded data can include the hours of usage, average pressure, leaks, and AHI. Other more advanced models will also be able to record if you are snoring and whether or not there are any limitations on air flow. All this information is recorded and stored on a memory card, or SD card, that can usually be removed and shared with your sleep specialist.

Air Filter

Your air filter is essential to not only your personal health but also to the health of your machine. Your CPAP air filter helps to capture foreign particles like dust, pollen, and other contaminants that can cause a lung infection. Without the air filter, these particles will collect inside the machine where bacteria will continue to collect and multiply.


The humidifier is another essential part of your CPAP machine. In general, a humidifier is used to add moisture to the air in a room. This helps people in the room to breathe more comfortably. Your CPAP humidifier works in the same fashion. The humidifier on your machine is heated to make the air more comfortable for you to breathe. This helps to lessen the amount of dry coughing and dry mouth.

If a sleep specialist has prescribed a CPAP machine, it is essential that you use it properly. Misuse of any of the pieces can not only mean that you don’t experience its full benefits, but you also take a risk with your respiratory health. You may also increase your risk of suffering from other diseases such as high blood pressure and diabetes. When you get your new machine, take the time to understand how it works and its individual parts. This will help you to ensure that your machine is being well maintained.
