# SpO2
|
||
|
||
Maxim’s proprietary algorithms for deriving clinical-grade accuracy pulse oximetry (SpO2) measurements from **Red and IR** PPG signals.
|
||
|
||
The algorithm uses the default settings for PPG measurements 2 and 3. Measurement 2 drives the IR (LED2) LED, and Measurement 3 drives the Red (LED1) LED. Both measurements sample PD1.

|
||
The HR algorithm uses the default PPG settings for measurement 1, which drives the Green (LED1) and samples PD2 and PD3. |
