ABSTRACT
Positive end expiratory pressure breathing (PEEP) is used to decrease morbidity and mortality in patients who are hypoxemic despite breathing oxygen in concentrations potentially toxic to their lungs. We reviewed the hospital course of 78 patients whose arterial oxygen tension (PaO2) was less than 70 torr despite a fraction of inspired oxygen (FiO2) of 1.0. Only 60 per cent of these patients were treated with PEEP and their clinical illnesses and severity of cardiopulmonary dysfunction were similar to those in patients not treated with PEEP. PEEP increased the length of survival from 4.2 to 9.2 days (P less than 0.05) whereas over-all survival, defined as hospital discharge, was similar at 31 per cent with and 26 per cent without PEEP. An improvement in PaO2 and decrease in shunt fraction following a trial of PEEP portends a favorable outcome, but its continued use appears to prolong life for a few days without affecting hospital mortality. Survival appears related more to the maintenance of adequate tissue oxygenation as manifested by a high mixed venous oxygen than to improved gas exchange as reflected by an increase in PaO2.
