Hello everyone again - I just had my pulmonary rehab assessment and was really looking forward to starting it, but, as I was doing the 6 minute walk, my oxygen levels dropped to 85 and heart rate was quite high (didn't make note of the actual number), so much so that the physio said the results were worrying for a person my age, suggested I may have to go back to hospital for additional tests, including cardio and that it may be safer to do the pulmonary rehab at the hospital too - admittedly I was walking fairly fast (much faster than i normally do, eg when going shopping or going for a walk), but I'm really worried now - has anyone else had a similar experience? What happened?
(ps I've got emphysema, moderate/severe)
