Apparatus for the monitoring and control of respiration
First Claim
1. A device for monitoring a subject'"'"'s physiological status comprising:
- first transducer means for producing a first signal representative of the physiological status;
respiration apparatus having an effect on the physiological status;
second transducer means for producing a second signal representative of a cyclical status of said respiration apparatus; and
processor means, coupled to receive said first and second signals, for producing an output signal dependent upon a relative phase of said first and second signals.

Abstract
A respiration monitor for measuring the respiration of a subject on a mechanical ventilator comprises first transducer means arranged to produce a first signal representative of a respiration status of the subject, second transducer means arranged to produce a second signal representative of a cyclical status of the mechanical ventilator, and processor means arranged to receive said first and second signals and to produce an output signal dependent upon the relative phase of said first and second signals. The invention extends to a method of monitoring, and also to a method of determining the rate at which a mechanical ventilator should be set in order to achieve 1:1 entrainment with spontaneous respiratory efforts.

22. A method for monitoring a physiological status of a subject, said method comprising the steps of:
-
producing a first signal representative of the physiological status of said subject using first transducer means; artificially respirating said subject with a respiration device to affect the physiological status of said subject; producing a second signal representative of a cyclical status of said respiration device using second transducer means; and producing an output signal which is dependent upon a relative phase of said first and second signals.
