I wear the full mask because I am a mouth snorer.
They found my sleep apnea when they did a heart cath. on me. They couldn't hardly get my test done because I stopped breathing so much. As soon as I woke up from the test my cardiologist told me that I had to have the test done for sleep apnea the next night. My heart and everything was ok, it was my sleep apnea causing everything. When they did the test, I stopped breathing 91 times in an hour. Since I have had the cpap machine I really sleep all night now.
