My mother, aged 76 (weight 74 kgs, height 5 2 ) has been using a manual CPAP for about 10 years. About 10 days ago, she started using an automatic CPAP machine (with a humidifier at 3.0) and is getting regular phlegm and in between a problem of choking and gasping for air. Could it be because of a change in machine or because of using a humidifier? What would advise? Thank you.
