Why blood oxygen monitoring is typically done on the finger rather than the wrist？
Measurement Accuracy
The finger has a higher density of blood vessels and a richer capillary network, allowing the pulse oximeter to more accurately detect blood oxygen levels. In contrast, the wrist has fewer blood vessels and lower blood flow, which may lead to less accurate measurements.
Signal Strength
On the finger, the sensor can more easily obtain a strong and...
