AN58128 - Blood Pressure Monitor with PSoC®

Blood pressure is one of the vital signs in the human body. It is measured using both invasive and non invasive techniques. This application note demonstrates how to build a non invasive blood pressure monitor using the PSoC® 1. This design does not use any external active components to buffer, amplify, and filter the signal.

Introduction

The non invasive method of monitoring blood pressure is widely used. It measures arterial systolic and diastolic pressures of the human body. This device can also measure heart rate. Table 1 describes various non invasive methods used in blood pressure monitors. This application note demonstrates how to use the PSoC to build an oscillometric blood pressure monitor.
