Man needs the vital oxygen to his organs, the brain and all cells.

After inhalation of the oxygen, the air is brought through the lungs into the bloodstream. The blood carries this oxygen into each cell of the body, so that there is enough oxygen for sufficient supply of the body.The measurement of the amount of oxygen and the saturation of the blood with oxygen is called oximetry.

For easy and absolutely painless examination only a "finger cot" with a small light source (LED) and a sensor is attached to a finger. So then the blood oxygen content can be accurately determined.With an eye-catching measurement result then additional tests, such as can pulmonary function for the clarification of the causes can be performed.
