Healthy Human Performance Tests

To meet ISO standards (80601-2-61) or FDA guideline adherence for clinical use, pulse oximeter performance must be tested in healthy humans in a laboratory setting. Independent device testing for the Open Oximetry Project follows our protocol consistent with ISO and FDA. Only devices labeled as ‘verified’ or ‘disputed’ have been independently tested by the Open Oximetry Project.
All other devices listed show data from manufacturers or published literature and have not been confirmed by the Open Oximetry Team. Scoring criteria will be modified based on evolving data on this topic. See the table below for scoring criteria for this category:

No Data

1 (red)
