What is the difference between Fixed Pressure and Auto Pressure CPAP Machines?

Which type of CPAP machine is right for you? The answer depends on your individual needs and preferences.

Continuous positive airway pressure (CPAP) machines are an effective treatment for sleep apnea. However, not all CPAP machines are created equal. There are two main types of CPAP machines: fixed pressure and auto pressure. Let's take a closer look at the difference between the two.

Fixed pressure CPAP machines

Fixed pressure CPAP machines deliver a constant pressure throughout the night, regardless of changes in the patient's breathing. These machines are set to a specific pressure by a healthcare professional, based on the patient's needs. The Resmed Airsense 10 Elite CPAP Machine is an example of a fixed pressure machine. It delivers a constant pressure throughout the night, ensuring that the patient's airway stays open and they receive the necessary amount of air to breathe properly.

Auto Pressure CPAP Machines

On the other hand, auto pressure CPAP machines (also known as APAP machines) adjust the pressure automatically based on the patient's breathing patterns. These machines use advanced algorithms to detect changes in the patient's breathing and adjust the pressure accordingly. The ResMed Airsense 10 Autoset CPAP machine is an example of an auto pressure machine. It offers the added benefit of automatic pressure adjustment, making it an ideal choice for patients who may experience changes in their breathing during the night.

So, which type of CPAP machine is right for you?

The answer depends on your individual needs and preferences. If you have a consistent breathing pattern, a fixed pressure CPAP machine may be sufficient for your needs. However, if you experience changes in your breathing during the night, an auto pressure CPAP machine may provide better results.
