The waveform of a pulmonary catheter, shown in the figure, is located in which of the following?
a. Right atrium
b. Pulmonary artery
c. Right ventricle
d. Pulmonary capillary with a wedge
ANS: B
The figure shows a systolic pressure of approximately 22 mm Hg and a diastolic of approximately 8-10 mm Hg. This falls within the normal pulmonary artery pressures of 15-35/5-15 mm Hg. The presence of the dicrotic notch is another hint that the catheter is in the pulmonary artery. The right atrial pressure is normally between 2 and 6 mm Hg. A catheter in the right ventricle would show pressures of 15-35/2-6 mm Hg. The pulmonary capillary wedge pressure (PCWP or PAOP) normally varies between 2 and 15 mm Hg.
