Respiratory failure & ventilation

Clinical evaluation of a smart wristband for monitoring oxygen saturation, pulse rate, and respiratory rate

J Clin Monit ComputPublished Diagnostic accuracy study

Authors' conclusion

This study shows that photoplethysmography-based SpO2, RR, and PR measurements can be accurate during heart catheterisations.

Study context

Population
Patients undergoing heart catheterisations945 samples
Participants
100 patients
Comparison
PPG-based wristband vs reference Nellcor fingerclip and 5-lead ECG
Outcome
Accuracy of SpO2, RR and PR vs reference (correlation coefficients and root mean squared error)
