Abstract

A physiological state is monitored by determining the electrical admittance associated with that state. The values of admittance may be displayed or acoustically represented, or form the basis of a control system.

Description

A Method of Monitoring Physiological Changes A Method of Monitoring
Physiological Changes In this invention physiological changes is monitored by a method other than by monitoring the voltage or magnetic output(s) of neurone(s).
At present physiological change is monitored by ultrasonic, NMR, impedance or similar scans.
In this invention a physiological state is monitored by monitoring its associated electrical Admittance or a suitable component thereof, at a frequency high enough to make the reactive component significant. The operator is supplied with any necessary connection(s), probe(s), contact(s) or inductive loop(s) required for monitoring electrical parameter(s).
If necessary the changes in the monitored factor may then be subject to whatever conditioning! pattern recognition is required to produce a defined output corresponding to what has been monitored.
In one implementation the admittance relating to blood flow pulsation is monitored between two hand electrodes, the admittance providing the timing element of a VCO charging circuit, the maximum voltage being sufficiently low to be safe.
The frequency/phase may then be converted for use in an ECG display or acoustic representation.

Claims (3)

  1. A Method of Monitoring Physiological Changes Claims 1) A system whereby
    a physiological state is monitored by monitoring the Admittance or a component thereof associated with the said physiological state.
  2. 2) A system as in 1) above where the factor monitored is used as the basis for an acoustic or visual representation.
  3. 3) A system as in 1) above where the factor monitored is used as the basis of a control system.
