Thank you so much for responding. I have called the onologist but never get to talk to him. Just the nurse. In fact I just talked to the oncology nurse this morning because he is showing signs of the co2 getting high again. She told me to take him to the emergency room or call the ambulance. When I talked about it to him, he refused to go. If he would refuse to go in the ambulance if I would call him, then I would just get a hefty bill that I can't afford to pay right now. So, I guess I will have to wait until he is unresponsive again and call for an ambulance again. I feel as if I am between a rock and a hard place.
