Title:
PHYSIOLOGICAL INFORMATION DISPLAY APPARATUS AND PHYSIOLOGICAL INFORMATION DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2024/034539
Kind Code:
A1
Abstract:
A physiological information display apparatus includes a reception unit configured to receive a start signal and an end signal, the start signal indicating a start timing of a treatment for a subject, the end signal indicating an end timing of the treatment, a calculation unit configured to calculate a moving average value of a pulse wave transit time of the subject, a hemodynamic parameter of the subject, using the calculated moving average value, and a change rate of the hemodynamic parameter in a period from the start timing to the end timing, based on the start signal and the end signal received by the reception unit, and a display controller configured to output, to a display, the change rate calculated by the calculation unit.
