One of the most common challenges that patients using a CPAP machine face is just becoming comfortable wearing the machine as it can take some time to get to the point where patients are able to fall asleep with it on. Some common complaints regarding the comfort of wearing the CPAP machine include not liking the air pressure both coming in and as they exhale, they feel claustrophobic or “trapped” while wearing the mask, they experience anxiety at the beginning since it is unfamiliar, or they accidentally remove the mask while they are asleep. It can also take some trial and error to find a size of mask that fits properly and is comfortable to wear the entire night, or they may need to try a different style of mask to see what works best for them. All of these feelings of discomfort can contribute to the patient struggling to fall asleep and stay asleep until they are completely used to wearing the mask, so this process can take some time before any benefits of wearing the CPAP machine can be realized.
