SpO₂ validation on the M5A

The M5A covers the full set: SpO₂, pulse rate, heart rate, waveform, NIBP, and temperature. But this round was focused — just SpO₂ accuracy. Fluke simulator to dial in controlled baselines, then real finger testing for real-world behavior.

We’re comparing one parameter on a multi-function monitor against dedicated single-purpose devices from the two brands the industry treats as reference standard. The spread was tight across every saturation level we tested.
