Abstract

OBJECTIVE: To compare the accuracy and efficiency of the respiratory rate RR RRate mobile application to the WHO ARI Timer. METHODS: Volunteers used both devices to measure RR from reference videos of infants and children. Measurements were compared using correlation, Bland-Altman analysis, error metrics and time taken. RESULTS: Measurements with either device were highly correlated to the reference r = 0.991 and r = 0.982, and to each other r = 0.973. RRate had a larger bias than the ARI Timer 0.6 vs. 0.04 br-min, but tighter limits of agreement −4.5 to 3.3 br-min vs. −5.5 to 5.5 br-min. RRate was more accurate than the ARI Timer percentage error 10.6% vs. 14.8%, root mean square error 2.1 vs. 2.8 br-min and normalized root mean square error 5.6% vs. 7.5%. RRate measurements were 52.7 seconds 95% CI 50.4 s to 54.9 s faster. CONCLUSION: During video observations, RRate measured RR quicker with a similar accuracy compared to the ARI Timer.
