I have found a great article that explains the difference between dyspnea and hypoxia, or the difference between being short of breath(SOB) and having low oxygen level in the blood.

We need to "keep on keepin on" if it is mere SOB and try to work trough it by learning how to control our breathing and building up the muscles that help us to breathe.

Hypoxia refers to the actual lack of oxygen in our blood. We need to be careful here and not let our oxygen levels drop below 89% or at the very lowest 88%.
