The Choice Model MD300C13 is based on Beijing Choice Medical's uniquely patented algorithms that use dual 'see-through' sensor technology for the accurate measurement of blood oxygen saturation levels and heart pulse rate. Beijing Choice Medical was the first oximeter manufacturer from China approved by the FDA for sale of its oximeter in the USA as a medical product.
Choice Model MD300C13 finger pulse oximeter will NOT monitor SPO2 during activity and movement. You must stop the current activity and take the reading while stationary. Movement will cause readings to be affected by artifact.
Aviation Pilots love Choice Model MD300C13 because it allows them to quickly assess their SPO2 while flying at high altitudes. Hypoxia can be a pilot's worst enemy, and the Choice Model MD300C13 finger pulse oximeter is a low-cost product which gives pilots peace of mind.
