A proper mask fit for a patient on a CPAP machine is very important. Sometimes patients have a hard time adjusting to wearing this device while sleeping and cannot get used to the apparatus on their face while trying to sleep.
Usually when a patient goes through a sleep study and a CPAP machine has been ordered, the patient will be given the same mask as they wore during their study. Sometimes it is hard to tell if you will like a certain mask until you have worn it a few nights with the CPAP device.
Some signs that your mask does not fit properly can be: waking up with dry mouth, hearing or feeling air coming out of the sides of your mask, feeling air leak into your eyes or a large leak is shown on your compliance download.
Let your doctor know if you feel your mask is not fitting properly and you can be fitted with a new mask. There are MANY types and brands of masks that you can chose from.
