Abstract
A method and system of distinguishing physiological pulses as measured by pulmonary artery catheterization. The method includes positioning two measurement devices in blood vessels of a subject, one in a major systemic artery and one in the pulmonary artery, and measuring blood pressure in the blood vessel with the measuring device to generate a pressure waveform. A phase difference between the two pressure waveforms is determined and used to create a warning or to display the phase difference on a display. The system includes an analysis module that determines phase differences based on the inputs from two or more physiological sensing modules.
