CPAP Pressure Settings – Finding the Right Level for You
Starting CPAP therapy can feel daunting, especially when it comes to CPAP pressure settings. Patients often wonder whether their machine is calibrated correctly or why therapy feels uncomfortable.
Getting your CPAP pressure settings right is crucial for effective sleep apnoea treatment, ensuring your airway remains open while maintaining long-term comfort. Understanding how these settings work helps you achieve the most natural and effective sleep therapy experience possible.

What Are CPAP Pressure Settings?
A CPAP machine delivers air at a specific pressure measured in centimetres of water (cmH₂O) to prevent your airway from collapsing while you sleep. The correct level is usually determined through a sleep study or titration testperformed by a clinician.
Types of pressure delivery include:
-
Fixed CPAP: Delivers a single, constant pressure all night.
-
APAP (Automatic CPAP): Adjusts pressure automatically within a prescribed range based on your breathing.
-
BiPAP (BiLevel PAP): Provides two distinct pressures—higher when you inhale and lower when you exhale—for additional comfort.
Modern devices display or record your CPAP pressure settings data, allowing clinicians to optimise therapy and track compliance.
Why Getting the Right CPAP Pressure Settings Matters
Correct CPAP pressure settings ensure your airway stays open while avoiding unnecessary discomfort.
-
Too low: Airway collapse can persist, leaving sleep apnoea untreated.
-
Too high: Can cause bloating, dryness, or difficulty exhaling.
-
Just right: Airway remains stable, breathing feels natural, and sleep quality improves dramatically.
The goal is to achieve the perfect balance—enough pressure to prevent apnoeic events but gentle enough for comfortable nightly use.
Adjusting and Monitoring CPAP Pressure
Your CPAP pressure settings should always be changed under medical supervision. If you experience discomfort, discuss your symptoms with your healthcare provider or sleep clinic. They can analyse your device’s compliance data and make safe adjustments.
Other troubleshooting tips:
-
Check your mask fit, as leaks can mimic pressure problems.
-
Ensure your humidifier and tubing are clean for accurate airflow.
-
Monitor your therapy reports through compatible smartphone apps.
Working closely with your provider helps fine-tune pressure for maximum effectiveness and comfort.

Conclusion – Getting Comfortable with CPAP Pressure Settings
Finding the right CPAP pressure settings is about balancing prescription accuracy with personal comfort. With professional guidance and advanced devices like APAP machines, you can achieve optimal therapy that supports restful, uninterrupted sleep. Consistent use of your CPAP at the proper pressure level will improve breathing, boost daytime alertness, and protect your long-term health.
