Review on Pulse Oximeter Fingertip: Digital Blood Oxygen Saturation Monitor For Heart Rate & SpO2 Level Monitoring - Portable LCD Pulse Oximeter With Batteries Included by Eduardo Davis

Wow/-/easy to use pulse ox. monitor that is not tight and doesn’t pinch at all.This device does just what it says:Pulse rate bpmPulse oxPI%heart rate "waves”Btw I did not know what PI % was before purchasing this. However, now I do⤵️Perfusion Index or PI % is—the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue (such as finger tip, toe, or ear lobe).—an indication of the pulse strength at the sensor site.The PI's values range from 0.02% for very weak pulse to 20% for extremely strong pulse.***With this device, it takes a full minute or two to get a completely accurate reading.***Great product especially with COVID possibility showing signs before a person can tell if it’s COVID or just the flu. This could help assess if a dr consult is needed to determine what is medically wrong. So this is an assessment device to assess if medical consultation and diagnosis is needed.Again, video shows just how easy this is to use and set up. Very basic set up for a complex instrument.I was not paid or compensated in any way for this review. I really just like to contribute reviews to make Revain a safer and better place to shop.
