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 …

The tip of the catheter lays into the main pulmonary artery, where the balloon can be inflated and deflated for measurement of pressures. Balloon can be inflated here to obtain pulmonary capillary wedge (or occlusive) pressure which gives an indirect assessment of left sided filling pressures.

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 …

A No. 5 Fr double-lumen catheter with a balloon just proximal to the tip is inserted into the right atrium under pressure monitoring. The balloon is then inflated with 0.8 ml of air. The balloon ...

The upper limit of normal of mean pulmonary artery pressure (MPAP) is 20 mm Hg , with a cut-off value for the diagnosis of pulmonary hypertension of 25 mm Hg . The upper limit of normal of the pulmonary artery wedge pressure (PAWP) is 12 mm Hg, with a cut-off value for the diagnosis of left heart failure usually agreed of 15 mm Hg . Errors up to 8 mm Hg …

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.

Obituary: pulmonary artery catheter 1970 to 2013 - PMC
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4175482/
The birth of the intermittent injectate-based conventional pulmonary artery catheter (fondly nicknamed PAC) was proudly announced in the New England Journal of Medicine in 1970 by his parents HJ Swan and William Ganz. PAC grew rapidly, reaching manhood in 1986 where, in the US, he was shown to influence the management of over 40% of all ICU ...

The PA catheter dynamic frequency response was checked in both the PA and wedge positions prior to obtaining any tracings according to the method of Gardner. 15 Briefly, the PA catheter was flushed with saline solution from a pressure bag to introduce a square wave into the recorded tracing. At the termination of the square wave, characteristic ringing occurs …
