Abstract

Pulmonary capillary pressure (Pcap) is a major factor of pulmonary ederna. Pcap would be valuable information, e.g., when assessing effects of a therapy on a critically ill patient. Pulmonary arterial pressure (PAP), central venous pressure (CVP) and pressure in the Swan-Canz catheter balloon were measured during pulmonary arterial occlusion procedure. An automatic method was developed to detect the instant of occlusion, to cancel the ventilation artefact and to compute the Pcap. Catheter balloon pressure was used to detect the instant of occlusion. Ventilation artefact was removed by applying adaptive filtering to PAP signal. CVP was used as the reference signal for the adaptive filter. Pcap was estimated using single exponential fit method.
