Figure 3: Schematic diagram showing U-shape course of pulmonary artery catheter in pulmonary artery (left panel). Transit time of warm blood from heating filament to thermistor is less as compared to the straight course of the catheter (right panel). RA: Right atrium, LA: Left atrium, RV: Right ventricle, PA: Pulmonary artery, TV: Tricuspid valve, PV: Pulmonary valve, PAC: Pulmonary artery catheter
