[|Human|] yes I know a person who has been on a breathing machine 14 times in less than a year. He has severe copd. He has been using a cpap at night but they are going to put him on a bipap. Will this help him get rid of his bad oxygene or carbon dioxide YYYY@YYYY
[|AI|]  Hello dear, thanks for your on Chat Doctor.CPAP means continuous positive airway pressure. In this mode a constant positive pressure is generated throughout the respiration (inspiration as well as expiration). So for expiration will be difficult for patient As he has to expire forcefully against the positive pressure. So expiration will not be completed, and therefore carbon dioxide level is rising in body. In BiPAP (Bilevel Positive Airway Pressure) we can adjust positive pressure in both inspiration and expiration. So inspiration pressure can be set high to improve oxygenation and expiration pressure can be set low to decrease carbon dioxide level. So BiPAP will be more beneficial to him than CPAP. Also ask him to enroll in pulmonary rehabilitation program for chest physiotherapy and deep breathing exercise. This will help in COPD symptoms.
