Abstract
The blood oxygen level is considered one of the important vital signs of the body. An oximeter is a non-invasive medical device for determining the oxygen saturation level in the blood and provides information that supports in defining the cardiorespiratory condition of a person. This device is not that accessible to many people considering its price and fixed functionality. With the advent of smart devices like the smart mobile phones, the functionality of an oximeter can be mimicked using the external peripherals and the signal processing capabilities of smartphones. This study aims to address not only the price of commercial pulse oximeters but also the reliability, maintenance, and most importantly, the accessibility of the pulse oximeters to common people similar to portable smartphones. The prototype is a custom-built oximeter with a 3.5mm port audio jack interface to an Android smartphone. The signal processing algorithm gets signals through a light interface touching the human finger, calculate the oxygen saturation levels, and display the values on the screen of the phone. The smartphone-based oximeter was tested with respondents and results show that the prototype is comparable to a commercial oximeter and the obtained measurements are within the set of acceptable limits which do not exceed a 2% deviation on the average. Device accuracy is more than 94% on real-time test and measurement. © 2020, World Academy of Research in Science and Engineering. All rights reserved.
