One less tube this morning.
The PA-catheter measures the blood pressure. But not the ordinary pressure, the one you measure with a cuff around your upper arm. That one measures the pressure with which the heart pumps out the blood in the body.
The PA-catheter on the other hand, measures the pressure of the blood that the heart is pumping to the lungs. You can’t place a cuff there – hence the PA-catheter.
