1. A portable blood pressure measuring apparatus comprising:
- a blood pressure measurer for measuring a wrist or finger blood pressure, wherein the wrist or finger blood pressure is an arterial pressure measured at a wrist or a finger;
a Pulse Wave Velocity (PWV) measurer for measuring a PWV;
a controller for controlling compensation of the wrist or finger blood pressure using the measured PWV so that the wrist or finger blood pressure corresponds to a brachial blood pressure; and
a display for displaying the compensated wrist or finger blood pressure,wherein the controller controls the compensation of the wrist or finger blood pressure using one of the following equations;
Pbrachial=a+b×
Pwrist or finger+c×
PWV
Pbrachial=a+b×
Pwrist or finger+c×
PWV+d×

Abstract
A portable blood pressure measuring apparatus and a method therefor are provided. In the portable blood pressure measuring apparatus, a blood pressure measurer measures a wrist or finger blood pressure being an arterial pressure at a wrist or a finger, a Pulse Wave Velocity (PWV) measurer measures a PWV, a controller controls compensation of the wrist or finger blood pressure using the PWV so that the wrist or finger blood pressure corresponds to a brachial blood pressure, and a display displays the compensated wrist or finger blood pressure.
