Pulse Oximeter, Fast and Accurate, Vivid OLED Display

A pulse oximeter is a small electronic device that estimates the saturation of oxygen in your blood. You want a number in the 95% to 100% range. If the number drops to 92% or lower, that's a cause for concern. That's generally the level where a doctor might put you on supplementary oxygen and keep you in the hospital for observation.
