@cinderellapong, this has to be a scary time. I'm sorry, but no one can provide sound medical advice over this, or any other, forum. I can sympathize with you, and the feelings of helplessness. Don't be shy about calling his doctor to report how the night went, and report concerns or decline in his condition. Keeping the office updated is a good way to get the feedback and attention that he may need. If his condition worsens overnight, don't rule out a visit to the Emergency Room. Do you have a home pulse oximeter? If yes, are his readings dipping?
