Combination of multiple light paths in pulse oximetry: the finger ring example.
When pulse oximetry is required at other body locations than the finger tip new strategies for optical setups and signal handling are required. In this paper we present a combination of short and long light paths that succeeded in resolving the problems associated to the development of a finger ring SpO2 sensor.
