Arterial oxygen content is associated with PEEP volume in patients without pulmonary disease

Abstract

Introduction: In patients with assistance mechanical ventilatory (AVM), the addition of PEEP determines a variable gas volume (PEEPVol) that contributes to improving gas exchange, reducing intrapulmonary shunt, and improving functional residual capacity, which is reduced by factors such as sedoanalgesia, relaxation, and supine position. Achieving an adequate end-expiratory lung volume could improve arterial oxygen content and survival.
Objective: to measure the relationship of the positive pressure volume at the end of expiration with the arterial oxygen content and the theoretical functional residual capacity.
