The required CPAP pressure does not directly correlate with the severity of sleep apnea. People with more severe sleep apnea do more often need higher pressures on CPAP or even bilevel therapy. This is especially true in the setting of obesity or nasal obstruction. Children may require similar pressures to adults, despite the smaller size of their airways. The anatomy of the upper airway and the nature of the airway obstruction has the biggest role in determining the required CPAP pressure setting.
If sleep apnea occurs because of a blocked nose due to allergies or a deviated septum, a collapsing soft palate , or a tongue that falls back into the airway, differing amounts of air are required to push these tissues out of the way. In addition, being overweight or obese may exacerbate things. Alcohol, medications that relax airway muscles like benzodiazepines , and sleeping on your back may all transiently add to your pressure needs.
Finally, REM sleep towards morning may relax muscles and exacerbate sleep apnea as well. Therefore, as described above, it is not easy to guess what CPAP pressure you may need to treat your degree of sleep apnea. It may also vary somewhat during the night depending on your sleep position and sleep stage. If the pressure is too low, your sleep apnea will not be adequately controlled.
If it is too high, you may experience side effects like mask leak or air swallowing. It is important to have the machine properly set by a sleep specialist to ensure the best experience with it and the greatest benefits. Modern devices can provide information on the residual AHI and this can help to guide the pressure adjustments. If you continue to have sleep apnea symptoms , get reassessed by your board-certified sleep medicine physician to ensure your condition is adequately treated by your machine's pressure settings.
Don't change the settings yourself as you may not fully understand the variables that contribute to the difficulties you may be experiencing. Tossing and turning night over night can have a big impact on your quality of life. APAPs automatically adjust your pressure throughout your therapy, which greatly reduces the chances of having a pressure that is too high.
EPR allows you to adjust between three different comfort settings to alleviate any feeling of breathlessness. Mask choice is extremely personal and varies from person to person. One that works well for you may be a poor fit for another CPAP wearer. While the severity of your sleep apnea plays a large role in determining your pressure, so do naturally occurring changes in your body, such as getting older, gaining or losing weight , or any other events that alter your physiology.

However, a nasal mask with a foam cushion can provide an airtight, comfortable seal for higher pressure settings. Also, a nasal mask with suction and side straps to secure the nasal mask so it will stay in place can be beneficial.
Nasal Pillow CPAP Mask - Nasal pillow masks have two pillow inserts that rest at the base of your nose, providing minimal contact with your skin. They are ideal for people who toss and turn in their sleep. By taking up less space it provides an increased field of view making it easier to read and watch TV before bed.
Its soft seal reduces pressure and prevents red marks while its QuietAir elbow disperses air over multiple vents for quieter sleep apnea treatment. The tube is connected at the tube of the frame to allow more freedom during the night.
By removing the tubing from the nasal bridge, less pressure is placed on the nose to reduce red marks and discomfort. The Simplus has a simple design that maximizes the ability to sleep peacefully. Use the velcro tabs to create a secure fit for stability that lasts the entire night. ResMed AirFit F30i Full Face Mask - Ideal for those who may feel claustrophobic in other full face masks, the minimal contact design of the AirFit F30i means that users are able to read, use a phone, or watch TV in bed, even if you wear glasses.
Because the tube connects at the top of the frame you can enjoy freely sleeping in any position without becoming entangled. Take advantage of more liberty as the hose connects at the top of the frame instead of the nasal bridge, allowing you to move freely during your sleep. In addition, the four-point headgear provides a secure fit and increased stability. While the average setting is 10 cmH2O, your setting will likely fall anywhere between 6 and 15 cmH2O.
If you have a CPAP machine , you use one pressure setting prescribed by your doctor for the entire night. Your pressure should be just enough to keep your airways unobstructed for a full night of sleep. When your pressure is too low, you can experience more apnea events than the normal 5 per hour as well as other symptoms like snoring or waking up gasping for air.
But, if the pressure is too high you can experience other side effects like uncomfortable therapy, problems with your CPAP mask, nasal congestion, and fitful, interrupted sleep.
