Abstract
This paper presents the design of non-invasive pulsoximeter using MSP430FG437 microcontroller. The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation, the pulse rate and the wave form of the heart-rate signal on the PC.In this application is used the same sensor for both hear-rate detection and pulsoximetering and the signal is transferred wireless mode. Light sources, typically light-emitting diodes (LEDs), shine visible red and infrared light. Deoxygenated hemoglobin allows more infrared light to pass through and absorbs more red light. Highly oxygenated hemoglobin allows more red light to pass through and absorbs more infrared light. The oximeter senses and calculates the amount of light at those wavelengths proportional to the oxygen saturation (or desaturation) of the hemoglobin.
