The Pulmonary Artery Catheter The pulmonary artery catheter (PAC) is a balloon tipped thermo dilution catheter cms long, that is inserted via a large vein and floated into the pulmonary artery. It is used to obtain haemodynamic measurements which together with clinical observations indicate how efficiently the heart is functioning. The pulmonary artery catheter has 3 vascular lumens that must be thoroughly flushed by the provider prior to insertion of the catheter into the sheath (blue proximal (CVP), white proximal (VIP) and yellow distal (PA) (Figures 9, 10). Sterility of the entire catheter and its ports must be maintained. 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. The interpretation of hemodynamic values and pressure tracings. The pulmonary artery catheter offers several advantages over central venous pressure monitoring. When the balloon tip of a Swan Ganz catheter is properly wedged in a branch of the pulmonary artery, the pressure sensed by the catheter tip represents that in the left atrium, taking aside a specific problem of pulmonary capillary wedge pressure monitoring in the septic patient.
The modern flow-directed pulmonary-artery catheter, also known as the Swan–Ganz catheter, was first described in the Journal 43 years ago. 1 The inflatable balloon at its tip permitted Cited by: 7.

When the catheters enters the RA, a CVP tracing is seen – characterized by a and v waves. 2. As the catheter enters the RV, a sharp increase in systolic pressure is noted. 3. As the catheter is advanced to the pulmonary artery, an increment in diastolic pressure is seen as well as the presence of a dichromatic notch. 4. Following the right ventricle, the catheter is advanced into the pulmonary artery. Typical pulmonary artery tracings resemble the right ventricular tracing slightly with a large slope upward, being more rounded at the top. The onset of diastole begins with the closure of the pulmonic valve, which produces a dicrotic notch on the pulmonary.
The pulmonaryartery catheter is generally cm long and 7 to 8 French in diameter. An airfilled syringe (A) is used to inflate the balloon at the catheter tip (inset). Introduction. Pulmonary artery catheterization (PAC) is a procedure in which an intravascular catheter is inserted through a central vein (femoral, jugular, antecubital or brachial) to connect to the right side of the heart and advance towards the pulmonary artery. This diagnostic procedure can be utilized to assess right sided cardiac chamber filling pressures, estimation of cardiac output, intracardiac Author: Mary Rodriguez Ziccardi, Nauman Khalid. 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. Pulmonary artery catheterization, or right heart catheterization, is the insertion of a catheter into a pulmonary artery. Its purpose is diagnostic; it is used to detect heart failure or sepsis, monitor therapy, and evaluate the effects of drugs. The pulmonary artery catheter allows direct, simultaneous measurement of pressures in the right atrium, right ventricle, pulmonary artery, and the filling pressure of the left atrium.
