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.
