How to Measure a Pulmonary Artery Catheter Pressure

With the pulmonary artery catheter, please we have the potential for measuring the pulmonary capillary wedge pressure. This can allow us to infer things like what the left atrial pressure is or what the left ventricular endostolic pressure is. The principle involves the tip being in a West Zone 3 branch vessel as mentioned. Once wedged, the displayed number will typically be a mean because if you look at the waveform it will be a little bit of a variation in that waveform if it's properly wedged.
