Pulmonary artery catheter

This picture denotes a typical pulmonary artery catheter (PAC) that has a catheter tip that is naturally curved. This PAC is over 100 cm, indicated with black graduations that occur at 10 cm intervals along the catheter length. A syringe is generally provided with most PAC kits to inflate the balloon located at the catheter tip by no more than 1.5 mL of air. Up to five ports are available for hemodynamic monitoring; this one shows three ports (yellow, red, and blue). The thermistor connector is also shown.
