Question

In drawing blood from the proximal channel of a pulmonary artery catheter, the attempt is to measure which of the following pressures?

a) Systolic Blood Pressure
b) Diastolic Blood Pressure
c) Pulmonary Artery Pressure
d) Central Venous Pressure

Answer 1

The pressure measured by drawing blood from the proximal channel of a pulmonary artery catheter is the pulmonary artery pressure.

Step-by-step explanation:

When drawing blood from the proximal channel of a pulmonary artery catheter, the pressure being measured is the pulmonary artery pressure. This involves an invasive procedure where a catheter is threaded into the pulmonary artery to transmit pressures to external measuring devices. The pulmonary artery pressure is an important indicator of how well blood is being transported from the right side of the heart to the lungs for oxygenation before it is sent out to the rest of the body.
