Developing a portable pulse oximeter for telemetry application

Abstract

Pulse oximeter is an optical medical device that measures heart rate and oxygen saturation level of the arterial blood in a non-invasive way. In this study a remote portable fingertip pulse oximeter was developed. The bluetooth connection of the device provides the data transfer between device and PC. The measured values of device can be stored on a PC as “xml” files. In this study, some physical activities were also carried out using the developed device. The effect of indoor and outdoor areas to the variability of oxygen saturation of blood during exercise was monitored and the average measured oxygen saturation of the participated volunteers during indoor and outdoor exercises were calculated and they were compared graphically.
