Oxygen Saturation (SpO2)
Last updated: December 2024
CardioMood measures blood oxygen saturation (SpO2) to provide insights into your respiratory health.
What is SpO2?
SpO2 measures the percentage of hemoglobin carrying oxygen. Normal levels are 95-100%.
How It Works
CardioMood uses red and infrared LEDs to measure light absorption through your skin. Oxygenated blood absorbs light differently than deoxygenated blood.
When SpO2 is Measured
- Overnight: Continuous monitoring during sleep
- On-demand: Manual spot checks
- During activities: If enabled
