Abstract
A device for determining the respiration rate and/or respiration depth of a patient includes a sensor for sensing heart sounds and an analyzer for analyzing the variation of the amplitude of the sensed heart sounds to determine the respiration rate and/or respiration depth from this amplitude variation. An apparatus for monitoring the respiration of a patient includes such a device and the analyzer is arranged to determine an anomaly in the amplitude variation of the sensed heart sounds as an indication of a respiration anomaly.
Claims27
A respiration detector comprising:
- a sensor which senses heart sounds emanating from a patient and for generating an electrical signal containing a signal component produced by said heart sounds, said signal component having a varying amplitude;
- and
- analyzer means, supplied with said electrical signal, for extracting said signal component and for analyzing variations of said amplitude of said signal component for identifying at least one of a respiration rate and a respiration depth from the variations of said amplitude.
An apparatus for monitoring respiration of a subject, comprising:
