Wifes ...pulse is going below 60 ..ie around 55 and oxygen falling below . Taking oxygen in hospital . Seems she has too much chest congestion. She is in hospital for the last 7 days (before that she was in home isolation for 6 days). They have given remdisivir steroid ..yesterday was the last dose. Her condition has not improved much in the hospital. She does not have sugar ...only little bp.. Will she improve ...how much time will it take .. ..ie to be out of oxygen...when his breathing will be normal ..ie at least out of danger...
