Figure 5From: How can the response to volume expansion in patients with spontaneous respiratory movements be predicted?Prediction of fluid responsiveness by ΔPP, PAOPee, RAPee and ΔRAP. The receiver operating characteristics (ROC) curve area was significantly larger for pulmonary artery occluded pressure at end-expiration (PAOPee) than for pulse pressure variation (ΔPP; p < 0.05). ΔRAP, inspiratory variation in RAP; RAPee, right atrial pressure at end-expiration.Back to article page
