SYNOPSIS With measurements of arterial blood gases and calculations of venous admixture at 2 levels of inspired oxygen, the relative roles of true right‐to‐left shunt and ventilation‐perfusion non‐homogeneity were examined in a group of infants with only moderately severe respiratory distress. They were considered to be of about equal importance, but because true shunts were never very large, imbalance in ventilation‐perfusion was the major cause of hypoxaemia in room air.
