PA Catheters Manufacturers

PA catheters are long catheters, which are introduced through large bore central venous lines usually in the subclavian or internal jugular veins. The catheters have a balloon at their tip, which allows them to be carried via the flow of blood or floated to their resting position within the PA. The catheter has a distal lumen, which allows for measuring PA pressures and obtaining mixed venous blood samples. A proximal lumen permits fluid infusions and manometric measurement in the right atrium. It measures cardiac output via a technique known as thermodilution. A small bolus of cold 5% dextrose is quickly injected into the right atrium via the proximal lumen of the PA catheter.
