The CMS Model 50-D is based on CMS's uniquely patented algorithms that use dual 'see-through' sensor technology for the accurate measurement of blood oxygen saturation levels and heart pulse rate.

CMS Model 50-D 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 CMS Model 50-D because it allows them to quickly assess their SPO₂ while flying at high altitudes. Hypoxia can be a pilot's worst enemy, and the CMS Model 50-D finger pulse oximeter is a low-cost product which gives pilots peace of mind.

*** BEWARE: Pulse Oximeters that state that they are not approved by the FDA are Non-Medical Devices that have not passed the stringent FDA 510k Pre-Market Approval Process ***

The CMS 50-D is an Oximeter that is FDA 510k Approved for Medical Use
