To answer Alice's question "Is he still on life support?"
Yes, he is. The oscillating ventilator is doing all the work for him. The only thing that his lungs are doing right now is the gas exchange. What this means is that his lungs get rid of the carbon dioxide. But the machine is doing the inhalation for him. His lungs are also absorbing the oxygen.
Right now we just went to visit him and he has a fever of 39.2. So now they are doing a bunch of cultures to see why he has a fever. He is still so sick and another infection on top of what he already has would be very serious.
