Abstract

Serial arterial P(O₂) values were obtained following discontinuation of supplemental inspiratory oxygen by face mask, in 21 patients suffering from a variety of cardiac diseases. All patients were free of pulmonary disease. Arterial P(O₂) values returned to baseline within 7 min after supplemental oxygen was withdrawn. Decay rate constants calculated from the arterial P(O₂) measurements were unaffected by cardiac index or the level of pulmonary capillary wedge pressure. It is concluded that in patients free of overt pulmonary disease, arterial P(O₂) measured 5 to 7 min after withdrawal of supplemental inspiratory oxygen accurately reflects an individual patient's baseline arterial P(O₂) value.
