Quizplus · Accepted Answer

The proximal port of a pulmonary artery catheter rests in the right atrium and is used to obtain central venous pressure.Central venous pressure is used to estimate the right-ventricular end-diastolic pressure.The distal port is used to measure pulmonary artery pressure.The distal port is also used to measure the pulmonary artery wedge pressure,which is an estimation of left-ventricular end-diastolic pressure.The thermistor is used to measure cardiac output.
