Quizplus · Accepted Answer

When a pulmonary artery catheter is in the proper position,the proximal port will be located in the right atrium and can be used to monitor central venous pressure.Cardiac output can be measured by using the thermistor a few centimeters from the tip of the catheter.The pulmonary artery pressure is measured by using the distal port without balloon inflation when in the pulmonary artery.When the balloon is inflated,the distal port will measure the pulmonary capillary wedge pressure.
