What Is a Pulse Oximeter?
Before diving into the specifics of pi, it’s essential to understand what a pulse oximeter is. A pulse oximeter is a handheld or clip-on device that measures a person’s oxygen saturation level in the blood. It works by shining a light through a small sample of blood, typically from a finger or toe, and measuring the amount of light that is absorbed or transmitted. This data is then used to calculate the percentage of oxygen bound to hemoglobin in the blood The details matter here. Surprisingly effective..
