ABSTRACT:
A system for measuring first and second fluid pressures within a patient comprising a valve having first and second positions, first and second conduits for providing communication between a fluid source and the valve, a pressure transducer coupled to the first conduit upstream of the valve, and third and fourth conduits for providing communication between the valve and first and second fluid pressures, respectively. When the valve is in the first position, it couples the first conduit to the third conduit, and the second conduit to the fourth conduit so that the pressure transducer can measure the first fluid pressure. When the valve is in the second position, it couples the first conduit to the fourth conduit and the second conduit to the third conduit so that the pressure transducer can measure the second fluid pressure. In both positions of the valve, fluid flows through the transducer.
