Abstract
There is provided a respiratory waveform drawing system. The system includes load detectors; a center of gravity position calculation unit; a waveform drawing unit configured to draw the respiratory waveform of the subject based on a temporal variation of the position of the center of gravity of the subject; and a drawing compensation unit configured to compensate a drawing state of the respiratory waveform. The drawing compensation unit includes a predictive waveform generation unit configured to generate a predictive waveform for the respiratory waveform of the subject based on the temporal variation of the position of the center of gravity of the subject in a past; and a correction distance calculation unit configured to calculate a distance between the respiratory waveform and the predictive waveform at a predetermined sampling time point, the drawing compensation unit being configured to compensate the drawing state of the respiratory waveform depending on the distance.
