Christian,
I had my surgery at the Cleveland Clinic just a couple of months ago and I was really impressed with the presurgery testing. The nurses, techs, doctors - everyone was extremely kind and (perhaps more importantly) on time. One tip I can offer - you've likely been given a long schedule with many different appointments on it. I found that for some of those (like chest x-ray, EKG, carotid check, etc) the appointment time is very flexible. So, if you have an hour break in your schedule before your next appointment, you can often get a later test done during that time and get out earlier in the day. It doesn't always work - Dr's and pulmonary functions seemed set in stone. Also, the care I received there after my surgery was fabulous. I don't think I ever waited more than 5 minutes for a nurse. Best of luck! Kate
