Hi, my husband had sleep apnea come on almost overnight from the swelling from lymphedema. There was quite a wait to get a sleep study done and then another delay of a week while we waited for the CPAP machine to come in. A couple nights were so bad I actually call the emergency room at the hospital and then threatened him if he didn't go see his doctor the next day I would call 9-11 the next night. His breathing was so bad he took 4 breaths and then nothing for 34-45 seconds. It was keeping me up night after night worrying about him not getting enough oxygen.

One thing that did work the last few nights before his machine arrived was sleeping on his side with his face close to a large fan on the night stand.

If your mother has sleep apnea she really needs an overnight study to determine which type of mask would work best for her and how much pressure she would need. Wish I could just send you our extra one.

Hope this helps.
