Warrants monitoring ventricular filling with rising PEEP in healthy anesthetized patients; leaves open effects in critically ill or cardiac populations.
Does positive end-expiratory pressure (PEEP) alter left and right ventricular diastolic filling dynamics in ASA physical status 1 female patients?
Increasing PEEP is associated with decreased preload and reduced compliance of both ventricles, which alters diastolic filling dynamics.
Yamada et al. (1999) studied this question.
