Swan-·Ganz cath·e·ter

(swahn ganz),
a balloon-tipped flexible catheter commonly used in the treatment of critically ill patients; introduced via a major peripheral vein, usually jugular or subclavian, and floated under pressure waveform guidance, with or without fluoroscopy, sequentially through the right atrium, right ventricle, and pulmonary artery, ultimately to wedge, when the balloon is inflated, in a small arterial branch where the tip measures pressure-transmitted retrograde from the left side of the heart, which is assumed to represent left ventricular end-diastolic pressure; side holes allow measurement of central venous pressure; with the balloon deflated, catheter measures pulmonary artery systolic, diastolic, and mean pressures; also allows infusion via catheter; some catheters are fitted with pacing electrodes.

Swan-Ganz cath·e·ter

(swahn ganz kath'ĕ-tĕr)
A thin (5 Fr), flexible, flow-directed venous catheter using a balloon to carry it through the heart to a pulmonary artery; when it is positioned in a small arterial branch, pulmonary wedge pressure is measured in front of the temporarily inflated and wedged balloon.
Synonym(s): pulmonary artery catheter.

pulmonary artery catheter

A catheter inserted into the pulmonary artery to measure pulmonary artery pressures, pulmonary capillary wedge pressure, and, indirectly, left atrial pressure and cardiac output.
