脈波と体動信号による睡眠指標

概要

This paper presents two sleep indices related with REM sleep and; awake and non-REM sleeps defined from the heart beat and body movement measured by the pneumatic method. The former is defined by the heart rate variability and latter is defined by channel capacity in the measurement of heartbeat, which is the degree of how the pulse wave measurement is corrupted with the body movement. These indices were compared with the occurrence rates of the delta-waves, spindle waves in the electroencephalogram and rapid eye movements measured by a polygraph and show the relationship with these bio-signals. The sleep stages estimated by using the indices were more accurate than those estimated by the conventional method based on the heart rate and body movement.
