Oxygenation and static compliance is improved immediately after early manual hyperinflation following myocardial revascularisation: a randomised controlled trial

Clarissa Blattner C, Guaragna JC, Saadi E.

This randomised controlled trial of 55 patients undergoing myocardial revascularisation assessed the effect of an early treatment of manual hyperinflation. After an hour in recovery, the experimental group received manual hyperinflation with positive end expiratory pressure followed by suction while the control group received suction only. Oxygenation and static lung compliance were measured immediately after suction.

PaO2 and static compliance were greater in the experimental group than in the control group. The experimental group was extubated 76 minutes earlier than the control group. Hospital length of stay and the incidence of post operative pulmonary complications were similar in the two groups.
