Pulse oximeter development often requires dependable performance feedback well before a formal regulatory accuracy study is initiated. During this stage, teams iterate on sensor hardware, algorithms, calibration curves, and signal-quality controls. To make meaningful progress, they need a repeatable way to compare performance across prototypes and study sessions.  A transfer standard helps fill that role. It is an intermediary pulse oximeter system with calibration traceable

For developers of pulse oximeters, respiratory monitors, and other physiological sensors, validating device performance under reduced...
