Severe Apnea with CPAP generally once a night
I have used CPAP for about 7 years. I seem to wake up regularly between 2:30 and 3:30 am most every night feeling like I have not been breathing and with a slight head ache. I then seem to sleep irregularly the rest of the night with less intense apneas occurring. When I wake up each time, I have been having a slightly weird dreams. According to myAir, my sleep results are generally 100 with few apneas during the hight with my CPAP gear. My question is should I be concerned with the one bad apnea I seem to have most nights that wake me around 3;00 am. This is generally an intense feeling of shortness of breath and somewhat scary. In the past I thought I might be experiencing a heart attack or other heart issue but I have been assured by cardiologist that my heart is OK. So, is one severe apnea episode a night unhealthy and cause for concern?
Thank you in advance for any advive!
