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 derived from the PAC is …

A Swan-Ganz catheter or right heart catheter is a quadruple-lumen catheter with a thermodilution sensor that is attached to a pressure transducer outside the body, with this transducer, is possible to determine the central vein pressure, right atrial pressure, right ventricular pressure, and pulmonary artery pressure. The catheters size range from 60 to 110 …

Lumens. blue = right atrial lumen = proximal injectate port -> terminates 30cm from the tip of the catheter lies within the right atrium when the tip of the catheter is in the pulmonary artery. This port can monitor RA pressures (RAP/ CVP) and receive the injectate for cardiac output studies. Can also be used to give fluids and drugs.

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 …

The proximal port (D) connects to an additional lumen 30 cm from the catheter tip and is used to monitor right atrial pressures once the catheter tip is in the pulmonary artery. A thermistor wire extends from the catheter tip to an electronic connector (E) and is used to measure cardiac output by means of thermodilution.

The PAC is 110 cm in length, marked at 10 cm intervals, and has at least 2 channels. The distal channel at the tip of the catheter allows for transducing pulmonary artery pressure (PAP) and SvO 2 sampling, while the proximal channel is used for measuring central venous pressure (CVP) and central venous saturation (ScvO 2) sampling. A balloon is located just below the tip of the …

Connect one of the pressure cables to the “PA” transducer. Turn the stopcock on the (PAP) pulmonary artery pressure transducer off to the patient (open to air). Transducer holder with transducers should be placed level with the patient’s 4th intercostal space in the midaxillary line. Select the “0- Zero” soft key.

After entering the RV, insertion of an additional 10 to 15 cm of catheter is usually sufficient to reach the pulmonary artery. Feeding excessive catheter while the tip remains in the RV can lead to coiling and possible knotting. The pulmonary artery pressure tracing (Ppa) is evidenced by an abrupt rise in diastolic pressure .
