Abstract
This paper introduces the design of a small and cost-effective optical pulse oximeter, including a finger clip, sensor readout electronics, and associated firmware. The device is based on widely-available commercial optical sensors that are designed for the wearables market and measure the reflection of different wavelengths of light. This design was produced in response to a request from the Royal United Hospital in Bath UK, in light of the severe shortage of clinical pulse oximeters during the 2020 COVID-19 pandemic. Products based on this design have not been submitted for medical device approval; the design documents here should be considered purely for research, educational and development purposes.
