Background
Pulse oximeters, more commonly known as a pulse ox, are used in many medical settings to measure the blood oxygen saturation level, or SPO2 levels. More often than not, these levels are used to help diagnose any possible respiratory disease and other complications a patient might have. It is a functional, non-invasive way of taking these measurements, and also readily available.
- SpO2 calculation is based on the change in amplitude of arterial blood absorbance.
- Darker skins absorb more infrared radiation, resulting in up to 4% in higher readings.
Introduction
Pulse Oximeters currently are not skin tone sensitive when recording oxygen saturation within blood. With this new device, skin tone will be taken into account when recording the blood oxygen saturation levels, resulting in a more accurate reading.
Problem Statement
A way to address variance in blood oxygen saturation level reading through photoplethysmography pulse oximetry caused by varying skin tones.
