Pulse measuring device

A pulse measuring device (10) includes a pulse wave detecting section (100) for detecting the pulse wave of the subject, an amplitude calculating section (112) for calculating the amplitude of the pulse wave, an interval calculating section (114) for calculating the interval of the pulse wave, an extracting section (116) for extracting the respiratory variation component varying with the breath of the subject from the interval, and a determining section (118) for determining that an apnea event has occurred when the amplitude decreases or the interval is shortened at a predetermined first point of time and when the respiratory variation component decreases at a predetermined second point of time immediately before the first point of time.
