DEVELOPMENT OF A PULSE OXIMETER AND BLOOD PRESSURE MEASUREMENT DEVICE

Ana Fé, Joana Sousa, Hugo Gamboa

Abstract

The aim of this study was to develop a device that measures both oxygen saturation (SpO2) and Blood Pressure (BP), non-invasively, continuously and without a cuff. The pulse oximeter was developed for transmission and reflection mode, for use in finger and wrist, respectively. The oxygen saturation results obtained with the developed device placed on the wrist reveled an high relation with an market device. For BP measurement there were tested 3 different combination of sensors localizations to obtain Pulse Transit Time (PTT): ECG and pulse oximeter on the finger, ECG and pulse oximeter on the wrist and pulse oximeter on the wrist and photoplethismogram on finger, and two calibration modes: for each subject - without input parameters - and general - with one input parameter (height). The results reveled better correlation between the BP estimated with the first calibration and the reference method (cuff-based) than for the second calibration.
