Abstract

In order to research and fabricate a non-invasive

continuous and real-time blood oxygen saturation monitor with wrist

use blood oxygen simulation front-end AFE4400 and main controller MSP430 for blood oxygen saturation

heart rate source data collection and processing based on the principle of photoplethysmography（PPG）. Blood oxygen saturation measurement algorithm and pulse rate measurement algorithm is respectively presented for blood oxygen saturation and pulse rate calculation. The prototype and Fluke Prosim8P standard are simultaneously used to measure 31 cases of blood oxygen saturation and 151 cases of puls

e rate. The root mean square error between Lab

SpO

and Std

SpO

is 0. 85 %

and correlation coefficient is 0. 995（P

0. 001）. The root mean square error between Lab

PR and Std

PR is 0. 289 bpm

and correlation coefficient is 0. 999（P

0. 001）. The experimental results show that the measurement results of blood oxygen saturation and pulse rate by the prototype and the standard has good consistency.
