the pulmonary artery catheter (pac) is used to measure pulmonary artery occlusion pressure or pulmonary capillary wedge pressure, which is intended to reflect left ventricular preload.69 however, pulmonary artery occlusion pressure is not a good indicator of preload. 70,71 the catheter measures pressure and not volume, the relationship is not …

The original pulmonary artery cathe- ter method to measure left-sided pressures was to “wedge” a very small catheter into a small pulmonary ar- teriole, the so-called “wedge” pressure measurement. Wedge pressure is not Ppao. Since collateral flow and vessel diameter are different, wedge pressure tends to be slightly lower than Ppao values.

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.

The upper limit of normal of mean pulmonary artery pressure (MPAP) is 20 mm Hg ( 10 ), with a cut-off value for the diagnosis of pulmonary hypertension of 25 mm Hg ( 1 ). 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 ( 1 ).

Interpretation of the pulmonary artery occlusion pressure …

Conclusions: In mechanically ventilated patients whose respiratory muscles produce large excursions in the Ppao, the end-expiratory Ppao is often much higher than the Ppao measured after muscle relaxation. The pre-relaxation mid-point Ppao and the relaxed Ppao are usually similar, but this may not be true in individual patients.

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 balloon is then inflated, which occludes the branch of the pulmonary artery and then provides a pressure reading that is equivalent to the pressure of the left atrium. Pulmonary capillary wedge pressure (PCWP) is frequently used to assess left ventricular filling, represent left atrial pressure, and assess mitral valve function.
