WebHowever, the two most common causes of hypoxemic respiratory failure in the ICU are V/Q mismatch and shunt. 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.

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.
