Abstract
This paper presents a prototyped novel chest-based Pulse Oximetry system, and reports on test results from comparative trials with a commercially available finger-based Pulse Oximetry system using several human subjects. The system was iteratively optimized through adjustment of optical component alignment (angular position, component distance, photosensitive area etc.) and through fine-tuning of LED intensity and receiver sensitivity. This work is significant and timely as it provides compelling evidence that SpO2 measurements from the chest offer a genuine commercial solution for bedside and ambulatory vital-signs monitoring.
