Primary Institution: Corsano Health B.V.
Hypothesis
The study aimed to evaluate the accuracy of photoplethysmography (PPG)-based monitoring of respiration rate during high-intensity interval training (HIIT).
Conclusion
The Corsano CardioWatch 287-2 wristband reliably monitors respiration rate during high-intensity physical activity.
Supporting Evidence
- The CardioWatch 287-2 showed an average root mean square error of 2.13 breaths per minute.
- The overall bias was nearly zero, indicating strong agreement with the reference device.
- The device effectively handled motion artifacts during high-intensity activities.
- Results were consistent across different demographic subgroups.
Takeaway
This study shows that a smartwatch can accurately track how fast you breathe while exercising hard, which can help doctors keep an eye on your health.
Methodology
The study was a single-center, non-randomized interventional trial comparing respiration rate measurements from the Corsano CardioWatch 287-2 with a reference ECG patch during HIIT.
Potential Biases
The study focused solely on healthy volunteers, which may not represent individuals with respiratory or cardiovascular conditions.
Limitations
The study had a small sample size and was conducted in a controlled environment, limiting generalizability to broader populations.
Participant Demographics
Participants included healthy adults aged 18 and older, with at least 30% male and female representation and diversity in skin tones.
