Little Doctor MD300 C23 Handheld Pulse Oximeter

The MD300C Series Handheld Pulse Oximeter is designed for continuous, non-invasive measurement of arterial blood hemoglobin oxygen saturation (saturation) and pulse rate. Oxygen saturation (saturation) is the percentage ratio of oxygen-bound hemoglobin (HbO2) to the total amount of hemoglobin (Hb) in the blood. Many respiratory diseases can lead to decreased oxygen saturation in human blood.

In addition, oxygen saturation may decrease due to the following factors:

anesthesia, serious postoperative trauma, side effects of some diagnostic tests.

That is why for the timely diagnosis by the doctor it is very important to know the value of the oxygen saturation of the patient.

The device is calibrated to display the functional oxygen saturation.
