Abstract
Abstract A respiration transducer apparatus for monitoring respiratory movement in patients is disclosed which includes a transducer for detecting respiratory movement in the patient's body. The transducer includes a first inductor adapted to be positioned adjacent a portion of the patient's body and a second inductor adapted to be positioned adjacent the same portion of the body. The transducers are disposed in a substantially fixed geometric relation as an integrally fixed coil with the first and second inductors inductively reacting with each other and a forming a continuous transducing area.
