Suggest Treatment For Sleep Apnea And Heart Issue

I'm waking up out of my sleep gasping for air. Like I haven't been breathing for a while.. It happened to me 3 times last night and now I'm a little afraid to go to sleep. From what I'm read it sounds like sleep apnea? My heart rate was 50 BPM n respitory was 14 per min. I also noticed that my lungs felt "heavy" like breathing was a little harder or that I had to remind myself to take breaths. I had to sleep on flat ony back since I had a c section on the 19th. I'm wondering what is causing this and how long might it last?
