Abstract

Pulse oxygen saturation is an important physiological parameter for monitoring oxygen content and respiratory function. It is very inconvenient that the pulse oximeter in the hospital use transmission probe and the data measurement have to be done in close range. Therefore, this paper designed a reflection pulse oximeter in tele-monitoring system. Firstly, a reflection oximeter which is based on reflection sensor DCM03 and microcontroller MSP430 is designed. Subsequently, Zigbee wireless module is integrated on the circuit board to realize remote measurement. Finally, the second derivative of photoplethysmography waveform derived from photoplethysmography signal is analyzed. Some experiments are conducted in the end and the method proposed maybe help confirming the relationship between SDPPG (second derivative of photoplethysmography) and human tired or diseases.
