ABSTRACT:
A method for monitoring cardiopulmonary events is disclosed. The basic method comprises looping an extensible conductor (14) in close encircling relation about the neck (12) of the subject (10), providing a signal indicative of the inductance of the loop, and monitoring the signal. This signal contains both qualitative and quantitative cardiopulmonary information. In accordance with another aspect of the method, an extensible conductive loop (14) is disposed in close encircling relation about the head such that the plane defined by the loop extends through the mouth. By providing a signal indicative of changes in the inductance of the loop, qualitative and quantitative information for mouth volume may be obtained.
