How is CPAP pressure determined?

What happens when CPAP pressure is too high?

If your CPAP pressure is too high, you may experience discomfort in your mouth, nose or airways, which can make it difficult to fall asleep at night, and cause your overall therapy to not work as well.

What is the average pressure setting for a CPAP machine?

10 cmH2O
Your CPAP pressure settings are measured in centimeters of water pressure, or cmH2O. Most CPAP machines are able to go as high as 25 cmH2O, but that is far too high for the average sleep apnea sufferer. While the average setting is 10 cmH2O, your setting will likely fall anywhere between 6 and 15 cmH2O.

What is the average CPAP air pressure?

Your CPAP device blows air into your airways to ensure your breathing is not obstructed during sleep. The air pressure delivered is determined by the pressure setting on your device. For most people, this CPAP pressure setting is set between 6 and 14 cmH2O, with an average of 10 cmH2O.

How much water do I need to adjust my CPAP machine?

The average machine can auto-adjust between 4 and 20 centimeters of water (cmH2O). CmH2O is the unit that measures the pressure in CPAP machines and the centimeters of water pressure. One cmH2O is the amount of (additional) air pressure needed to raise a column of water by one centimeter.

What should I do if I can’t exhale through my CPAP?

If you find yourself struggling to exhale while using a CPAP or APAP machine, talk to your doctor about switching to a BiPAP instead, which has a different pressure setting for inhaling and exhaling.

What happens if your CPAP pressure is too low or high?

When the pressure is too low, you may suffer symptoms of sleep apnea. If the pressure is too high, you may struggle with the device, have nasal congestion, and experience choppy or fragmented sleep. Your CPAP, APAP, or BiPAP pressure needs may change over time.
