- as well as the and successors of the these watches
- unfortunately, we do not have time for testing ourselves
- the accuracy of the Polar H10 when use for respiratory rate has already been determined in a paper in Sensors:
https://pubmed.ncbi.nlm.nih.gov/34451093/
- preliminary results of our testing:
- Garmin Venu is accurate at about 12 breath per minute, and breathing rate has strong fluctuations
- Garmin Fenix is accurate at about 12 breath per minute, and breathing rate has lesser fluctuations
- We suppose that both watches calculate respiration rate on respiratory rate estimation, and that both watches are not calibrated
- We suppose that the most accurate device is the Polar H10 with Polar Sensor Logger app & Matlab Respiratory Rate Estimation Toolbox which most probably also runs in Octave
- The last option is a bit complicated, but the most promising option if we want accurate respiration data
- We are looking for a tester who tests it for fun and in his spare time.
