Abstract
There is provided a respiratory waveform drawing system. The system includes load detectors; a center of gravity position calculation unit; an oscillation coordinate setting unit configured to perform: obtaining a first extreme point at which a distance between an initial origin and the position of the center of gravity of the subject is maximized; obtaining a second extreme point which appears at an opposite side of the initial origin from the first extreme point, and at which a distance between the initial origin and the position of the center of gravity of the subject is maximized; setting a direction connecting the first and second extreme points as a direction of a tentative oscillation axis; and setting a midpoint between the first and second extreme points as a tentative oscillation origin; and a waveform drawing unit configured to draw the respiratory waveform.
