If you have been using your ResMed AirSense 10 for a while and feel as though your therapy could be more comfortable perhaps you are waking with a dry mouth, struggling to exhale against the airflow, or still feeling tired in the mornings the question of pressure adjustments is likely on your mind. This guide walks you through what you need to know, and how to do it safely.
Understanding Pressure on the AirSense 10
The ResMed AirSense 10 range includes three main variants the AutoSet, the Elite, and the AirSense 10 for Her. Each operates slightly differently when it comes to pressure delivery. The AutoSet, for instance, adjusts airflow automatically throughout the night within a set minimum and maximum range. The Elite delivers a fixed, consistent pressure. Understanding which model you have is the first step before making any adjustments.
Pressure is measured in centimetres of water pressure (cmH₂O). Standard therapeutic pressures typically fall somewhere between 6 and 14 cmH₂O, though some patients require higher settings. Your clinical prescription will specify either a fixed value or an acceptable range.
What the Clinical Menu Is
The AirSense 10 has two layers of settings. The standard user menu controls comfort features such as ramp time, EPR (Expiratory Pressure Relief), and humidification. The deeper clinical menu also called the provider or clinician menu is where pressure thresholds live. This level is intentionally less accessible to avoid accidental changes.
Step-by-Step: Accessing and Adjusting Pressure Settings
Before you begin, ensure the machine is plugged in but not running. Have your prescribed pressure values to hand so you can confirm the correct figures.
- Power on the device. Press the home button to reach the main screen. Ensure you are on the home display you should see the therapy pressure reading and a clock.
- Enter the clinical menu. Press and hold the home button for a few seconds, then simultaneously press the Start/Stop button. On most AirSense 10 units, this combination unlocks the clinician interface.
- Navigate to pressure settings. Use the scroll dial on the right-hand side of the machine to move through the menu options. You are looking for options such as "Min Pressure", "Max Pressure" (on the AutoSet), or simply "Pressure" on fixed-mode devices.
- Select and adjust the value. Press the dial to select a setting, then rotate to increase or decrease the figure. Values change in increments of 0.2 cmH₂O. Set the value as directed by your clinician.
- Confirm and exit. Press the home button to save your changes. The device will return to the home screen. Your new setting is now active.
Key Settings to Be Aware Of
EPR (Expiratory Pressure Relief)
This is a comfort feature, not a clinical pressure setting. EPR reduces the airflow slightly when you breathe out, making it easier to exhale against the machine. It can be set from 1 to 3, or switched off entirely. Many users find EPR helpful if they experience difficulty breathing out during therapy.
Ramp Time
The ramp function starts your therapy at a lower pressure and gradually increases to your prescribed level over a set period typically 5 to 45 minutes. This is useful if you find the full pressure uncomfortable when first falling asleep. Ramp settings live in the standard user menu and can be adjusted without entering the clinical area.
Humidity and Heated Tube
If you are using a HumidAir humidifier chamber alongside a ClimateLineAir heated tube both of which are compatible accessories available for the AirSense 10 you may find that adjusting humidity levels alongside your pressure changes can significantly improve comfort, particularly in winter months when indoor air tends to be drier.
When to Contact Your Clinician Instead
There are situations where adjusting your own settings is not the right answer. If you are experiencing any of the following, speak to your sleep clinic, GP, or respiratory therapist before touching the machine:
- You are still feeling excessively tired despite regular CPAP use
- Your AHI (apnoea-hypopnoea index) is rising, as shown in the myAir app
- You are experiencing frequent centrally-originating apnoeas (not obstructive ones)
- You have recently changed medications that may affect breathing
- You have gained or lost a significant amount of weight
Weight changes in particular can meaningfully alter the pressure required for effective therapy. A repeat sleep study or pressure titration session may be appropriate.
Keeping Your Equipment in Good Shape
Adjusting pressure is only one part of getting the most from your therapy. Regular maintenance of your mask cushion, headgear, tubing, and humidifier chamber plays a significant role in how effective and comfortable each session feels. A worn cushion causes air leaks, which can actually make the machine work harder and increase the delivered pressure beyond your prescribed level. Replacing mask components on schedule typically every three months for cushions and every six months for frames is genuinely worth it.
If you use a ClimateLineAir heated tube alongside a HumidAir chamber, ensure you are cleaning both regularly and checking for any signs of condensation build-up, which can affect airflow consistency.
Frequently Asked Questions
Will adjusting the pressure void my machine's warranty?
Accessing the clinical menu itself does not void the warranty on a ResMed AirSense 10. However, making changes outside of a clinical prescription could affect the effectiveness of your therapy and may have implications for any insurance or NHS-funded equipment agreements. Always check with your provider before making changes.
How do I know if my current pressure setting is working?
The myAir app from ResMed connects to your AirSense 10 via Bluetooth and gives you nightly therapy scores, including AHI, mask seal, and hours of use. A consistently low AHI (below 5 events per hour) is a good sign that your current setting is effective. If your scores are declining, that's worth discussing with your clinician.
Can I use a different mask with my AirSense 10 without changing the pressure?
Yes switching between compatible mask types (full-face, nasal, or nasal pillow) generally does not require a pressure change, as the machine maintains the prescribed output regardless of mask type. That said, different mask styles can affect how pressure is perceived. A full-face mask at the same setting may feel different from a nasal pillow mask, so give yourself a week or two to adjust whenever changing mask style.
