covid

I have a brother-in-law that had covid and been on a ventilator for about a month and a half. My sister has opted to bring him home to die. Is their anything that can be done for him other than make him comfortable. 

Don't lay him down flat, put him in a recliner chair and make him hack up the junk in his throat that is stopping him from breathing... hacking hard is the secret to life., he has to clear his throat.
