FAQs
What is a normal SpO2 reading?
Normal blood oxygen is 95-100%. Readings below 90% may indicate a health issue and you should see a doctor. Athletes may see temporary drops to 92-94% during high-intensity exercise.
Is a finger clip oximeter accurate?
Yes, clinical-grade finger oximeters are ±2% accurate. Consumer versions may vary ±3-5%. They work best on fingers with lighter skin tone — less accurate on darker skin.
Can I monitor SpO2 while sleeping?
Yes, wearable oximeters (like Viatom) and smartwatches (Apple Watch, Garmin) can monitor SpO2 throughout the night and detect sleep apnea events.
Do I need a pulse oximeter for fitness?
Not essential, but helpful if you're training at high altitude or doing intense HIIT where oxygen saturation may drop. Fitness trackers also provide HR and general activity data.
