[|Human|] I am on bi-pap 18/14 with a ramp setting of 5 for 45 minutes, I have the humidifier at the lowest setting, over the past 6 weeks I have been on steroids and 3 different antibiotics. When I use the bi-pap after 2 hours start coughing, sort of a barking sound that won t stop until I turn off the bi-pap machine. I am concerned witChatDoctorpliance issues, I have contacted the hotline for bi-pap and my pulmonary doctor with no answers. I tried the machine again around 11 p.m. and to turn it off, I had not used the machine for the past 3 days and had no coughing attacks. I have COPD, I also use Flonase with no relief please any suggestions
[|AI|]  Hello dear, thanks for your question on Chat Doctor. Since you are having barking type of coughing only with BiPAP use, in my opinion you are having problem in tubing of the BiPAP machine. After long time use, tubing s of BiPAP machine tend to develop Humidification, serrations, excoriations, colonization of the bacteria etc. You are improved and not coughing, since you have stopped BiPAP. So possibility of above-mentioned things is high. So better to change the tubing and start using new tubing.
