Does LifeWatch Generation 2 measure blood oxygenation (SpO2)?

Yes, thanks to the patent-pending and innovative clinical-grade fingertip sensors, LifeWatch Generation 2 functions as a pulse oximeter. It can measure the peripheral oxygen saturation (SpO2) level in a non-invasive and safe method. You can constantly monitor oxygen saturation and prevent issues related to poor blood oxygenation.
