The pulmonary artery catheter (PAC; Swan-Ganz or right heart catheter) can be used for a variety of clinical purposes. Interpreting hemodynamic data from PACs is important for the diagnosis and management of a range of conditions including shock and pulmonary artery hypertension ( table 1 ). The interpretation of hemodynamic values and pressure tracings …

Simultaneous absolute pulmonary artery wedge (Ppw) and esophageal (Pes) pressure tracings with electrical subtraction of Pes from Ppw in a patient with airway obstruction ( left) and plot of changes in Pes and Ppw in 10 such patients ( right ). High Ppw suggestive of left heart failure returns to normal after Pes subtraction.

Pulmonary artery occlusion pressure (Ppao) in a spontaneously breathing subject poststernotomy. The lines below the tracing indicate inspiration. Ppao falls relative to atmosphere during inspiration because the surrounding pleural pressure falls relative to atmospheric pressure. However, when pleural pressure is measured, Ppao most often falls less than pleural pressure, …

The accuracy of pulmonary vascular pressure measurements is of great diagnostic and prognostic relevance. However, there is variability of zero leveling procedures, and the current recommendation of end-expiratory reading may not always be adequate. A review of physiological and anatomical data, sup …

Measurement and results: Thirty-eight of 60 PCWP tracings were confirmed valid by the aspiration of pulmonary capillary blood. In the remaining 22 tracings, mixed venous blood was aspirated with the balloon wedged, and tracing validity was unconfirmed. Reviewer accuracy in identifying was 50 percent for R1, 65 percent for R2 and 57 percent for R3.

Pulmonary Artery Catheter Also known as the Swan-Ganz catheter, the PAC has had perhaps the most storied journey as a hemodynamic monitoring modality in critical care. This invasive method involves placement of a central venous catheter into the internal jugular vein.

the pulmonary artery tracing. (Normal Value 15-25 mmHg systolic, 8-15 mmHg diastolic) Headley, J. M. (2002). With the balloon still inflated, the catheter is advanced further until it finally wedges in a central branch of the pulmonary artery. At this point, right heart pressures and pulmonary influences are occluded.
