Myocardial Function during Low versus Intermediate Tidal Volume Ventilation in Patients without Acute Respiratory Distress Syndrome

Conclusions In patients without ARDS, intermediate tidal volume ventilation decreased left ventricular and right ventricular systolic function compared to low tidal volume ventilation, although without an effect on diastolic function.Editor ’s PerspectiveWhat We Already Know about This TopicLower tidal volume mechanical ventilation is associated with reduced ventilation induced lung injuryWhat This Article Tells Us That Is NewWhat is not known is if lowerversus intermediate tidal volume mechanical ventilation is also associated with improved systolic and diastolic left ventricular and right ventricular myocardial functionThis study of 42 mechanically ventilated patients who did not have acute respiratory distress syndrome found that lower tidal volume mechanical ventilation was associated with increased right and left ventricular systolic function but not improved diastolic function
