Key result
A low-cost, non-invasive device for measuring heart rate and blood oxygen saturation was successfully designed using an Arduino microcontroller and a MAX30100 sensor.
Why the study?
The study was conducted to examine how heart rate and blood oxygen saturation can be measured from a finger, processed, and displayed using a small, non-invasive, real-time device.
The paper outlines the engineering design of a low-cost, non-invasive pulse oximeter and heart rate monitor for potential home use.
Use of technology in healthcare is growing importance as a result of the tendency to acquire chronic disease like heart attack and high blood pressure. Heart rate and blood oxygen saturation is a couple of such biometrics that is monitored in this project to provide information regarding the health of the body. By measuring the intensity change of light transmitted through tissue due to arterial blood, heart rate is measured. Furthermore, oxygenated blood has different light absorption characteristics than deoxygenated blood under red and infrared wavelengths. Comparing the absorptions produce an estimate of the oxygen saturation of blood. The purpose is to examine how heart rate and the oxygen saturation of subject is measured from finger and then processed and displayed. The design, is small in size, easy to use, allows a non- invasive, real time method to provide information regarding health. This enables an efficient and economical means for managing the health care. This document is intended to be used by engineers, medical equipment developers, anyone related to medical practice and interested in understanding the operation of pulse oximeter and heart rate monitoring system.
