COVID-19 can bring on what's called COVID pneumonia an infection in which the lung's air sacs fill with fluid or pus. And it's possible that someone infected with the novel coronavirus might be in the early stages of COVID pneumonia including a drop in blood oxygen level without experiencing any difficulty breathing.
In such cases, a Pulse Oximeter might signal that you're in trouble before you realize it.
This Pulse Oximeter can measure and monitor Heart Rate, SpO2 and Pulse Intensity with high accuracy. Displays waveform (plethysmograph) and digital readings, as well as pulse bar graphs, to visually indicate any irregularities or abnormalities, such as weak heartbeat. FDA 510(K) Cleared.
The Pulse Oximeter also displays your Perfusion Index or Pi (Pi is the ratio of the pulsing blood to non-pulsing blood flow in your finger and is used to indicate the strength of blood flow to your finger). Your perfusion index changes based on whether the blood flow to your body is going up or down, and whether the arteries in your fingers are narrowing (causing your fingers to feel colder) or widening (causing your fingers to feel warmer).
Directions of use:-
Pulse Rate Range: Up to 240 BPM, Oxygen Saturation Range : 70% SpO2 to 99% SpO2
