Figure 3 Biexponential curve fitting for estimation of pulmonary capillary pressure (Pcap) by intersection of the fast and the slow components of the pressure decay curve, or by the extrapolation of the exponential fitting of the slow component of the pressure decay curve to the moment of occlusion. Modified from Souza et al. Critical Care 2005, 9: R132-R138.
