The ChoiceMMed MD300C2 is a fingertip automatic pulse oximeter. Information regarding the accuracy of its oxygen saturation measurement technology does not appear to be available. Oxygen saturation measurements are taken from the finger. It is intended for self-measurement and home use.

While the technology used in the ChoiceMMed MD300C2, to measure peripheral oxygen saturation, has been declared, on the manufacturer website, as being equivalent to that used in a clinically validated device, no evidence has been published to show that the devices have been compared according to a protocol compliant with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.
