WebIntroduction. Impaired peripheral oxygenation (IPO) of exercising muscles is caused by impaired circulation and/or mitochondrial function and a low arterial oxygen content, such that oxygen cannot flow adequately to myocytes. 1 The mechanisms of IPO are quite different from those of hypoxemia, mostly due to respiratory pathology.

These can be distinguished from each other by their response to oxygen. V/Q mismatch responds very readily to oxygen whereas shunt is very oxygen insensitive. A classic cause of V/Q mismatch is a COPD exacerbation. graphic tee for queenWebThere are several different ways that access liquid can accumulate inside the alveoli. The first that comes to mind is Congestive Heart Failure. This condition results from the heart becoming unable to adequately pump blood to the rest of the body. Therefor, the blood will begin to back up and leak into the lungs causing respiratory distress. graphic tee french
