PROBLEM TO BE SOLVED: To provide a new method etc. for evaluating respiration stability.SOLUTION: A method for evaluating respiration stability uses, as an index, a variation value obtained from processes including: (1) a process of acquiring waveform information on a respiratory air flow in a predetermined measurement period; (2) a process of detecting a period and amplitude of each respiration waveform from the acquired waveform information; (3) a process of calculating an inclination value from a ratio of the detected amplitude (A) to the detected period (t); (4) a process of creating a histogram by using the calculated inclination value; and (5) a process of calculating a variation value on the basis of the created histogram.SELECTED DRAWING: Figure 3 |
