- Abstract
Background: As one of the vital signs, the respiratory rate is an important index of general health in an initial examination. The duration of respiratory rate measurements is known to influence the results in adults. We examined the difference in respiratory rate measurements between two measurement durations in a pediatric population. Methods: The prospective, cross‐sectional study was conducted from November 2017 through March 2018 at Tokyo Metropolitan Children's Medical Center and analyzed differences in the respiratory rate in a 1 min group and 30 s group using the Bland–Altman plot. Results: Ninety‐five patients were enrolled. The median age was 0.99 years, and 50 patients were male. The correlation between the results of the 30 s and 1 min measurement durations was good (r2 = 0.970, P < 0.001; Spearman's rank correlation). The mean difference between the 30 s and 1 min measurement results was 0.86 (95% confidence interval: 0.27–1.45). Conclusions: The shorter measurement duration may result in overestimation of the respiratory rate, especially in young children or children with tachypnea. Nonetheless, the shorter measurement times correlated well with the 1 min measurement, and the difference was less than one per minute compared with the 1 min measurement. Thus, this method may be able to detect life‐threatening conditions earlier than longer measurement times.
