The PA catheter directly measures aright atrial pressure, right ventricular and pulmonary artery systolic and diastolic pressures. Through the inflation of a balloon at the catheter big top and resultant occlusion of a pulmonary artery branch, pulmonary artery capillary wedge pressure (PACWP) can be measured. This indirectly measures left ventricular end-diastolic pressure (LVEDP) and therefore reflects the functioning of the left side of the heart. Other measurements include: ? Cardiac return studies through thermodilution ? Mixed venous group O saturation (SvO2) ? shopping center body temperature ? Other derived indices include: oxygen delivery and consumption, the oxygen extraction ratio, systemic and pulmonary vascular resistance, left and right ventricular stroke work index.

Complications: Ventricular arrhythmias: irritation of the catheter upside as it moves through the ventricle on insertion or when catheter tip migrates back into the ventricle Knotting or coiling of catheter on insertion Pulmonary infarction: catheter tip wedged for prolong period or formation of thromboemboli Pulmonary artery sever: overinflation of balloon while in wedge position.
