METHOD AND APPARATUS FOR MEASURING CHANGE IN BLOOD PRESSURE BY RESPIRATION CONTROL
First Claim
1. A blood pressure measuring apparatus for measuring a change in blood pressure caused by respiration control, the apparatus comprising:
- a blood pressure measuring module for measuring blood pressure by pressurizing and depressurizing a cuff; and
a controller for measuring a number of respirations per minute based on a heart rate when a respiration exercise begins, inducing respiration of a subject until the number of respirations per minute reaches a predetermined number of respirations per minute, calculating a pulse transit time during the respiration exercise, and calculating and outputting a blood pressure value associated with the pulse transit time.

Abstract
A method and an apparatus are provided for measuring a change in blood pressure caused by respiration control. A number of respirations per minute is measured based on a heart rate when a respiration exercise begins. Respiration of a subject is induced until the number of respirations per minute reaches a predetermined number of respirations per minute. A pulse transit time is calculated during the respiration exercise, a blood pressure value associated with the pulse transit time is calculated, and the blood pressure value is outputted.
