More doctors are concerned that ventilators are killing people rather than helping. Suggestions are to use nasal oxygen delivery or CPAP machines. This is ince blood oxygen is low but some patients can breathe OK. Also it is becoming clear that red blood cells are being made incapable of transporting O2 and CO2. One suggestion that I did not find again was to give a whole blood transfusion to increase blood oxygen while waiting for medicine to do it’s job.
