Finger Pulse Oximeters

Oxygen saturation (OS) is the percentage of oxygen-bound hemoglobin (HbO 2) to all binding hemoglobin (Hb) in the blood, which is the concentration of oxygen in the blood. It is an important physiological parameter of the respiratory and circulatory system.

Many diseases of the respiratory system may cause the decrease of oxygen saturation in the blood of the human body. In addition, anesthesia-induced dysfunction of the body's automatic regulation, major surgical trauma, and some medical examinations may lead to oxygen supply problems and reduce the oxygen saturation of the human body. Symptoms such as dizziness, weakness and vomiting can be life-threatening. Therefore, timely checking of patients' oxygen saturation is helpful for doctors to discover problems in time, which is of great significance in the field of clinical medicine. The finger pulse oximeters are small in size, low in power consumption, easy to use and easy to carry. As long as the finger is inserted into the finger-sleeve photoelectric sensor, the display screen will directly display the measured oxygen saturation value. Clinical trials showed high accuracy and repeatability.
