A continuous pulse oximeter is a non-invasive device that measures blood oxygen saturation (SpO2) and pulse rate. For healthspan, its primary value is in identifying previously undetected nocturnal hypoxia (drops in oxygen), often associated with sleep-disordered breathing like sleep apnea. Addressing such issues can significantly improve sleep quality, reduce systemic inflammation, and lower cardiovascular risk, all of which are foundational to healthy aging.
Verdict
A valuable tool for screening for nocturnal breathing issues like sleep apnea.

Protocol
- Worn on a finger or wrist, typically during sleep to gather nocturnal data.
- Data is reviewed to identify trends in oxygen desaturation or heart rate variability.
Flags
- Consumer-grade devices may have lower accuracy than clinical-grade equipment.
- Data requires proper interpretation; consult a physician for diagnosis of conditions like sleep apnea.
- Focusing excessively on data can lead to health anxiety or orthosomnia.
