Choicemmed Pulse Oximeter MD300C21



Choicemmed pulse oximeter MD300C21 is a compact blood oxygen meter for blood oxygen saturation level (SpO2) and heart rate at home, medical clinics (hospitals, emergency room, doctor’s office), exercise and high-altitude activities. MD300C21 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 infants and children.

Normal oxygen saturation level range at sea level is bewteen 96% and 99%. The number would be lower at high altitude as the oxygen is thinner.

The ChoiceMMed oximeter MD300C21 displays the plethysmograph (pleth), which looks like a sine wave. Each wave corresponds to a heart beat. The wave amplitude shows the amount of blood floating through the blood vessels. Low amplitude means low blood perfusion or poor blood circulation. From the heart rhythm, one can observe various heart conditions, such as missed beats, tachycardia, bigeminy…

MD300C21 can show data in six different directions. The patient does not have to read the display upside down or sideway.
