Ello,
I've recently been going through a LOT of tests on my heart and lungs, and things seem to always be coming back with mixed signals largely due to my being an athlete. In the midst of waiting for my doctors' words I've been doing quite some research of my own. One of my symptoms is that my oxygen easily drops to 94% in easy-moderate exercise, and steadily drops to 91% during threshold & peak performance. Through my research I've found in some studies it's not normal, and in other research I've seen it quite common and not cause for large alarm.
Just wondering if anyone else out there has tested their oxygen during training and saw similar oxygen levels. And if so, if anyone has got other input on it being a cause of worry and/or what may cause the hypoxemia.
Cheers,
Leah
