So my mom has been told that she would benefit from using a cpap machine. She has had it for about four days now and hasn't been able to use it. At first she was just basically refusing to figure it out, then when she tried it she said that she couldn't breathe. Last night was the best when she lasted 1 1/2 hours before she gave up. Maybe claustrophobia? Does anyone have any tips or tricks we could try to get her used to it?
