A member asked:

I had a stress test done for my heart. awhile ago and my oxygen levels drop a lot towards the end. the cardiologist didn't say anything about it. should be considered or does that just happen during a stress test some times? the stress test was good?

A doctor has provided 1 answer

Drop in O2 sat: You don't mention what your oxygen saturation was (? by finger oximeter) before, during and at the end of exercise.I assume you achieved your goal of 85% of maximal heart rate, had no symptoms of signs of myocardial ischemia. If your oxygen saturation dropped below 90%, and especially if you were short of breath I would be concerned about pulmonary disease.and would consult a pulmonologist
