Kevin,I know you'd like answers, but please ignore most responses from this forum, describing their experience.You are unique (thank you God) and your experience will be unique.Simply talk with your medical team about your surgery.They will NOT have the answers you want, but must respond with generalities, like "...normally, the ICU stay is 28 hours (or whatever)...".Same with all your other questions. Your experience may or may not be "normal". Healthy people have struggled for months after OHS and so-called unhealthy people have recovered quickly and gone back to work in 6-8 weeks. There are lots of variables that determine the timeframe.
You will be given rather detail post-operative instructions, again somewhat "cookie cutter" items. It is important that both you and your caretaker understand and follow the instructions. If you experience any complications, you will have a phone number to call (24x7) or if "serious", get to the emergency room.(Personally, I was blessed with an ideal OHS and recovery experience, but that is irrelevant to you).Good luck and have a great day.Don
