i I have just seen the consutant with a view to getting this procedure. I know there is a long way to go to see if I am suitable, but the ball is rolling so to speak. I just wanted to know if the person was on oxygen at the time. I am going for the full breathing tests on wednesday, then go back to the clinic in 2 months time. I was looking for some insight into what is entailed, so if anyone can help it will be much appreciated.
