The Fora TN'G SPO2 (TD-8255B) is an 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.

There appears to be no peer-reviewed clinical validation information available on the technology used in the Fora TN'G SPO2 (TD-8255B) to measure peripheral oxygen saturation. However, this device appears to be very similar to another device by the same manufacturer or a device within a family of equivalent devices. At least one validation needs to be published and equivalence needs to be proven according to a protocol compliant with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.
