Abstract

This paper deals with the instrumentation development for heart rate and oxygen saturation using NIOS II
soft-core processor. In this day and age checking oxygen saturation and heart rate is essential in healing centers to
monitor low oxygen levels in blood. We have designed a novel soft-core processor running on NANO DE0 board with a
finger probe consisting of two LED's (660nm/940nm) and a single silicon photo-detector with transimpedance amplifier
to measure the absorption of ratio for two wavelengths. This system is used to monitor oxygen saturation in blood and
heart rate for 5 different subjects. The result was verified with another Pulse oximeter for 20 measurements on 5
different subjects. It was discovered that the readings taken were very close to the Pulse oximeter
