Adjusting the pressure on your ResMed AirSense 11 is a straightforward process that ensures your therapy remains effective and comfortable. Whether you are increasing pressure for better apnea control or decreasing it for improved comfort, the steps are consistent across the AutoSet line. This guide will walk you through the necessary settings on the device itself and within the myAir profile, empowering you to manage your therapy with confidence.
Understanding Pressure Settings
The ResMed AirSense 11 operates using an AutoSet algorithm that dynamically adjusts pressure throughout the night based on your breathing patterns. While the machine decides the optimal level in real-time, the settings you configure act as guardrails. The minimum and maximum pressure ranges you define ensure the device never exceeds your prescribed limits or drops below a therapeutic threshold. Changing these settings allows you to fine-tune the experience, balancing efficacy with personal comfort.
Adjusting Min and Max Pressure on the Device
To change the pressure range directly on the AirSense 11 screen, follow these steps:
Power on the unit and tap the home icon to access the main menu.
Navigate to "Settings" by tapping the gear icon, usually located in the top right corner.
Select "Pressure Settings" or "Treatment Settings" from the list of options.
Choose "Minimum Pressure" and "Maximum Pressure" using the up and down arrows.
Set the minimum to your lower prescribed limit and the maximum to your upper limit, then exit to save.
What the Numbers Mean
Prescriptions are often written as a range, for example, 8-14 cm H2O. The minimum pressure (8 in this example) is the baseline level the machine will start at, while the maximum (14) is the ceiling it will reach if your symptoms worsen. Setting these correctly ensures the AutoSet algorithm has the flexibility to help you without exceeding safety boundaries.
Modifying Settings via the myAir App
The myAir app serves as the remote control for your therapy, allowing you to manage settings from your smartphone. To adjust pressure ranges through myAir, open the application and select your AirSense 11 unit. Navigate to the settings menu and look for the pressure parameters section. You can often adjust the minimum and maximum limits here, with changes syncing wirelessly to the device overnight. This method is ideal for patients who prefer not to navigate the small screen of the machine.
Checking Your Compliance Data
After changing the pressure settings, monitor your usage statistics within the myAir app. The AHI (Apnea-Hypopnea Index) graph will indicate whether the adjustments are working. If your AHI remains high, the pressure might still be too low. Conversely, if you notice increased snoring or discomfort, the pressure might be too high. These metrics help you determine if your new settings are effective.
When to Adjust vs. When to Consult a Professional
Minor tweaks to the pressure range are generally safe if you are following the parameters set by your sleep specialist. However, significant deviations from your prescribed range can compromise treatment. If you feel the therapy is ineffective or uncomfortable after adjusting the settings, it is important to contact your doctor or sleep specialist. They can order a new sleep study or provide a new prescription to better match your current needs.
Maintaining Your Equipment
Pressure changes will not be effective if the hardware is compromised. Ensure the tubing is free of leaks and the mask cushion seals properly against your skin. A leak in the system can cause the AirSense 11 to lose pressure, making it feel like the machine is not working correctly. Regularly cleaning the filter, tubing, and mask ensures that the airflow remains constant and the pressure readings are accurate.
