CARDIONPULMONARY FUNCTION EVALUATING APPARATUS AND CARDIONPULMONARY FUNCTION EVALUATING METHOD |
摘要 |
A cardiopulmonary function evaluating apparatus includes: an electrocardiogram measuring unit which is configured to measure an electrocardiogram of a subject; a photoplethysmogram detecting unit which is configured to detect a photoplethysmogram of the subject; a heart rate calculating unit which is configured to calculate a heart rate (HR) of the subject based on the electrocardiogram; a PWTT calculating unit which is configured to calculate a pulse wave transmission time (PWTT) of the subject based on the electrocardiogram and the photoplethysmogram; an SV calculating unit which is configured to calculate a stroke volume (SV) of the subject based on the heart rate and the pulse wave transmission time; and an outputting unit which is configured to output a state related to the stroke volume of the subject based on the stroke volume that is calculated by the SV calculating unit. |
