Looking for clinical grade SpO2-meter (blood oxygen saturation) that sits on 2nd finger limb
Hi, I hope so much someone else in this forum tracks their SpO2 (blood oxygen saturation) too. The problem:
- smartwatches are inaccurate because they cannot shine through the wrist. Thus they use reflectance oxymetry which is less accurate. This is why no smartwatch (Apple Watch, Samsung Watch, fitbit, ...) has FDA approval for its SpO2 measurement. And never will, unless a major invention will come, increasing accuracy
- Fingertip-sensors such as the Masimo oxymeter provide world class measurement, but are unpractical in real life when using fingers (sports, typing...). I have killed my expensive Masimo Spo2 while doing sports.
So does anyone know an SpO2-sensor that sits on the second finger limb (the second phalanx), thus uniting the advantages of both?
Would you share experiences?
I am particularly interested in continuous Spo2-recording over hours
Thank you !!!
