Choosing the right CPAP machine can make a big difference in your sleep apnoea treatment. The two main types of CPAP machines—Fixed Pressure and Auto Pressure (APAP)—each offer unique benefits. Understanding how they work can help you and your healthcare provider select the best option for your needs.
A fixed pressure CPAP machine delivers one constant level of air pressure all night long. This pressure is set by your sleep specialist based on the results of your sleep study.
Best for:
Users with stable, consistent breathing patterns
Those who have already undergone titration to determine their ideal pressure
Example:
ResMed AirSense 10 Elite
Auto-adjusting CPAP machines monitor your breathing in real time and automatically adjust the pressure as needed. This makes them more responsive to changes like sleep position, congestion, or REM sleep.
Best for:
Users whose pressure needs vary throughout the night
People new to CPAP therapy who haven't had a titration study
Example:
Philips Dreamstation Automatic
Fisher&Paykel Sleepstyle Automatic
Fisher&Paykel Sleepstyle PLUS Automatic
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.
With the right machine and proper usage, you can experience improved sleep and better overall health.
💡 Tip: Always consult with your healthcare provider before choosing a machine. Consistent use—regardless of type—is key to improving sleep quality and long-term health.
