1. A monitoring apparatus for non-invasively monitoring physiological parameters of an individual comprising:

  • a monitoring garment comprising a shirt for the torso of the individual to be monitored, one or more inductive plethysmographic (IP) sensors, each IP sensor comprising an inductance sensor including at least one conductive loop arranged to closely encircle the torso, wherein the inductance of the conductive loop is responsive to the cross-sectional area of the torso enclosed by the loop, a cardiac cycle sensor for generating signals responsive to occurrence of cardiac ventricular contractions, a signal cable for carrying signals from said sensors, and a microprocessor unit comprising a microprocessor for receiving signals from said signal cable and for recording digital data derived from all received signals in a removable computer-readable memory media.
