Fig. 5From: The haemodynamic effects of crystalloid and colloid volume resuscitation on primary, derived and efficiency variables in post-CABG patientsPmsa, (Pmsa − CVP) and power during crystalloid and colloid resuscitation. Pmsa increased in both series and remained elevated for the time course of 60 min. The pressure gradient (Pmsa − CVP) stayed elevated in the colloid series, but deteriorated from t20 onwards in the crystalloid series. Power increased significantly in both series but only stayed elevated in the colloid seriesBack to article page
