Christen1,
What you're describing sounds like breathing pauses. Most people experience this occasionally, but if the pause lasts longer than 10 seconds, then that's called an apnea. First try to avoid eating close to bedtime and the same for alcohol. Sleep on your side or stomach. Weight gain after pregnancy can aggravate this problem. If it doesn't go away, you may want to consider seeing a sleep specialist.
An AHI of ii times per hour is considered mild. Take a look at my articles on sleep apnea for other options.
From a recent sleep study, I stop breathins 11 times per hour. Is this considered severe? I just can't stand the idea of the CPAP machine. Afraid I would never use it and ok with the consequensis. Help!!
