ABSTRACT
It has previously been shown that patients who have undergone mitral valve replacement (MVR) tolerate a positive end expiratory pressure (PEEP) of 1.0 kPa better than patients who have had aortic valve replacement (AVR). the difference was explained by the fact that the mitral patients had pre-existing pulmonary vascular disease. In the present study the effect of PEEP up to 2.0 kPa is investigated in three types of operations aortocoronary bypass graft (ACBG), mitral valve replacement, and aortic valve replacement; there were five patients in each group. We found that our mitral patients tolerated PEEP better than the two other groups, and that tolerance was not correlated to a higher pulmonary vascular resistance, but rather to a higher level of pulmonary capillary wedge pressure. The influence of PEEP varies in different types of patients and the effect is still difficult to predict.
