Mouth oximeter put to the test: can it measure oxygen correctly?
NCT ID NCT06267976
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested the ProSomnus RPMO2, a small device worn inside the mouth that measures oxygen levels and pulse rate. Researchers compared its readings to standard blood tests in 12 healthy adults. The goal was to see if the device is accurate enough for medical use.
