ABSTRACT:
A measurement corresponding to the intrathoracic pressure within the body of an individual can be obtained through the use of a transducer. The transducer used includes a movable actuator and is held with reference to the body so that the actuator engages the soft tissue above the suprasternal notch of the individual. As the transducer is located in this manner the actuator moves in accordance with the movement of such tissue as the individual breathes. As a consequence of the operation of the transducer during such movement of the actuator an electric signal is obtained which corresponds to the individual's intrathoracic pressure. An appropriate conventional circuit may be used to indicate such pressure.
