thank you very much for the extremely interesting and well done video. I have a question about CPAP I read that a high percentage of patients complain when undergoing this technique and very much prefer BiPAP. Why do they continue with a technique that is not well tolerated by patients ? A friend of mine who died of covid in the hospital when they placed a CPAP helmet onto him he wanted to tear it off As a response i think they sedated him No more complains after that Actually he died two weeks later No more complains ever thank you very much and best regards, gino

i need to asck some Questions Regarding Adjusting THE O2 Valve and Air Valve for CPAP thearpy by using Helmet or face masck
