I was told I have moderate OSA, I get about 17-19 an hour from the report. Got my CPAP machine, a Philips Resperonics with THE HEATED HUMIDAFIRE, and I use a nose pillow. I am not sure what my preassure is or how to tell. My AHI average on the machine info is at 3.5. I tried for acouple of weeks but hated the effect or suffocating feeling it gave me. When I dont sleep with the CPAP, I wake up one or more times with a rapid heart rate, and a really dry mouth. If I sit up my HR goes faster. This will last for about 5-10 min at the most, and then I calm down. What is puzzling I dont ever hear of anyone describing this symptom. Is it just me or is this a symptom of OSA. When I do use the machine I dont wake up like that but I do still wake up a few times in the night form the mask being on my face. Just wondering in case I may want a second opinion or another direction. Things I do notice that make me sleep better are: Not eating large meals or chocolate 4 hours before bedtime, taking my prilosec at bedtime(I have GERD), using my nasal spray my sleep doctor prescribed me, going to sleep earlier. Thaks for any help.
What you are experiencing is called hyperventilation. It is often an early symptom of Sleep Apnea. I had it for a period of 15 years before I was diagnosed.
Once you have obstructions you get too little oxygen in the blood. If this level gets too low, you will wake up and breathe very quickly. This will quickly give you too much oxygen in the blood, which is the really cause of your symptoms.
When you hyperventilate, it feels like you're about to die, although the condition is completely harmless.
CPAP treatment will eliminate these symptoms. Therefore it is important to achieve good CPAP compliance.
