Model 3230 Bluetooth^® LE Specifications

Oxygen Saturation Display Range: 0% to 100% SpO2
Pulse Rate Display Range: 18 to 321 beats per minute (BPM)
Declared Accuracy*: The table below shows A_rms values measured using the Model 3230 in a
clinical study.

This graph shows plots of the error (SpO2 – SaO2) by SaO2 using the 3230 with a linear regression fit and upper 95% and lower 95% limits of agreement. Each sample data point is identified by subject from a clinical study in non-motion conditions.

Pulse Rate Declared Accuracy Range (A_rms)*: 20 to 250 BPM ±3 digits
Low Perfusion Pulse Rate Declared Accuracy Range (A_rms)*: 40 to 240 BPM ±3 digits
