1/ How well do Corvid patients fare on ventilators?

Not well, according to gradually accumulating data. The death rate is high compared to other ailments.

It’s a prolonged torturous process, and the patient can’t be visited, except digitally.

2/ So, some patients may choose (and must be able to insist) that they NOT be vented.

They may prefer to stick with oxygen via cannula, some appropriate drugs, and a family member or care partner on hand.

If they die, it is gentler exit, on terms they chose.

3/ The next level would be the ability to take the oxygen and drugs and professional oversight HOME.

At present, hospice can’t provide this. But something needs to.

Right?

4/ (Personally I’m in fine health, but I’m 81, and I’m developing an informed opinion that going on a ventilator is not for me, should I face that choice as a Covid patient.)

Your mileage may vary.
