ChoiceMMed Finger Pulse Oximeter เครื่องวัดปริมาณออกซิเจนในเลือด ChoiceMMed pulse oximeter MD300C13 is a compact blood oxygen meter for checking pulse rate and blood oxygen saturation level (SpO2) at home, medical clinics (hospitals, emergency room, doctor's office), exercise and high-altitude activities. MD300C13 is fast and can return a reading within a few seconds. It has a finger chamber for adult fingers; however with care, it can also be used for infants¹ and children¹. Normal oxygen saturation level range at sea level is between 96% and 99%. The number would be lower at high altitude as the oxygen is thinner. A pulse oximeter is inexpensive and versatile. It should be a standard tool kit in all household's medicine cabinet. There are many useful applications, from hypoxia, general health, sleep apnea to heart attack. MD300C15D comes in an integrated unit and yields accurate and reliable SpO2 results. The pulse bar also indicates the pulse strength for doing simple assessment. To conserve the battery, the unit would shut off automatically after 8 seconds when not in use. With the neck lanyard, MD300C13 can be carried around your neck while doing exercise or working in high altitude.

If not, you would get a bad reading.
