Summary for Patent: 4,813,431
Title: Intrapulmonary pressure monitoring system
Abstract:A pressure sensing device hydraulically coupled with a transducer comprising a closed hydraulic system incorporated within an endotracheal tube to monitor intrapulmonary pressure. The tube employs an hydraulic system for conveying pressure data from a distal sensor, on the tube, to a transducer. The sensor and transducer are connected by a liquid-filled lumen. Use of an hydraulic conduit avoids the errors of gas-filled systems because liquids, such as the water used in this system, are incompressible.
