Abstract
A sleep monitoring system includes an ECG device () and a respiration inductance plethysmogram () which monitor cardiac activity and physical (ribcage) respiration respectively and feed representative signals to a digital data processor. Operations (-) process the beat interval data, while in a second thread, operations (-) independently process the amplitude modulation of the ECG data caused by the respiratory motion of the subject. The inductance plethysmogram device () provides an input to the processor which represents respiration as directly monitored independently of the ECG. Operations (-) process this direct respiration data independently and in parallel, in a third thread. All extracted features are fed to a classifier which in step (10) combines selected combinations of features to make decisions in real time.
