Abstract

Double-site transcutaneous oxygen pressure (tcPo₂) monitoring was carried out in 24 infants with cyanotic heart disease and in 12 acyanotic "control" infants. The tcPo₂ values were recorded continuously as ambient forced inspiratory oxygen (FIO₂) was varied from 0.21 to almost 1.0. The recordings obtained in the cyanotic infants could be grouped in one of four patterns, each of which correlated closely with the altered hemodynamic characteristics of heart disease. These data confirm the value of this noninvasive technique for hemodynamic and anatomic diagnosis of cyanotic heart disease, especially in cases with aortic arch anomalies with reversed ductal shunts.
