Pulse oximeter - measurement of oxygen saturation

The Berry Pulse Oximeter is the answer to the demand for a lightweight, affordable monitor to measure SPO2 oxygen saturation and heart rate in the office, home health care and sports environments. The pulse oximeter allows you to detect a drop in oxygen saturation before the onset of severe symptoms and take action quickly.

It can measure your blood oxygen saturation (SpO2) - your SpO2 level is an estimate of the amount of oxygen in your blood. An SpO2 level of 95% or more is generally considered a normal oxygen level.

Why is oxygen in the blood important?

The fact that oxygen is essential for human life is well known. The air we breathe contains oxygen. The human lung is the organ where the inhaled oxygen enters the bloodstream and reaches all the cells in the human body.
