Abstract
A non-contact respiratory monitoring system comprises a magnetic microwire sensor coil that detects magnetic field changes due to motion of a magnet attached to a patient's chest. Field lines emanating from the magnet are parallel to a circumferential loop area of the coil and the coil is positioned at a distance to magnetically couple to the magnet. Impedance in the coil changes when the distance of the magnet to the coil changes due to the patient's breathing. An alternating voltage across coil is modified by the change in impedance. An impedance analyzer coupled to the coil applies the alternating voltage and measures the impedance changes. A computer system controls operation of impedance analyzer, receives respiratory monitoring information based on the coil's impedance changes from the impedance analyzer, and generates a graphical display of the respiratory monitoring information.
