Abstract:
1. A method for acquiring analysis data concerning a respiratory disease, comprising the steps of: detecting a blood oxygen saturation and a body motion of a subject at a predetermined sampling frequency concurrently and respectively sequentially; expressing data concerning the detected blood oxygen saturation and data concerning the detected body motion along a common time axis; acquiring analysis data concerning a relation between a change in the blood oxygen saturation and the body motion of the subject based on the blood oxygen saturation data and the body motion data expressed along the common time axis; and calculating the subject's required oxygen flow rate based on a relation between a unit exercise amount or the sum of the unit exercise amount, and a time-based change of the blood oxygen saturation, with the unit exercise amount corresponding to a summation of the body motion information for a predetermined unit time based on the body motion data.
