How to Design a Better Pulse Oximeter

July 12, 2021 by Analog Devices Download PDF

White Paper Overview

It is more important than ever to design medical devices that are more convenient and less power hungry. This article covers the fundamentals of SpO2 measurement and demonstrates how a new generation of optical analog front ends (AFEs) can help create a better oximeter. The new devices can have reduced design complexity, a reduced burden on the mechanical design, and decreased power consumption.

Topics Covered:

  • The Recent Link Between COVID-19 and Hypoxia
  • The Urgent Need for a Better Pulse Oximeter Now and in the Future
  • What Is Oxygen Saturation?
  • How Does a Pulse Oximeter Work?
  • Calibration
  • Design Considerations
  • Solutions from ADI
