Re: It's not just the mechanicals that are needed
Yes, you are correct, in extremis you need to paralyse the diaphragm (possibly a curare derivative) and have a crew to operate the system.
However even a positive pressure air system ventilator that's kitbashed together, and works acceptably, can help a less serious case and can be the difference between recovering at home and ending up in hospital.
This has happened before - government officials getting a broom up their ass and killing people as a result - the Spanish flu in the UK is a prime example - the CHO of the British government was more concerned about fighting the war than pandemic flu, he ended up committing suicide from the guilt.
GOVERNMENTS if people are offering help, expertise and creative solutions accept it. We are not in a place where we can go by the book or by normal procedures.
