Abstract

Abstract A manifold assembly is provided for monitoring hemodynamic pressures. The manifold assembly comprises a base having first, second and third flush valves mounted thereon. A first three port stopcock is also mounted on the base having one of its ports in fluid flow communication with the first flush valve. One of the ports is in fluid flow communication with an arterial catheter and one of the ports is in fluid flow communication with a pressure monitoring means for determining arterial pressure. A first T-connector is fastened to the second flush valve. A second T-connector is fastened to the third flush valve. A second three port stopcock is mounted on the base with one of its ports in fluid flow communication with the second flush valve through the first T-connector. One of the ports of the second three port stopcock is in fluid flow communication with the third flush valve through the second T-connector.
