Despite being the least frequently monitored vital sign, respiratory rate has been demonstrated to be one of the most sensitive predictors of poor patient outcome. Recorded respiratory rates are often incorrect and higher than directly observed rates, possibly because care providers estimate the rate or count over a fraction of a minute and multiply to obtain the recorded rate.([FOOTNOTE=Semler, M. W., Stover, D. G., Copland, A. P., et al. Flash mob research: a single-day, multicenter, resident-directed study of respiratory rate. Chest. 2013;143(6):1740-1744.],[ANCHOR=],[LINK=]) Furthermore, subtle changes in respiratory rate over time may be indicative of evolving patient deterioration.([FOOTNOTE=Lynn, L. A., & Curry, J. P. Patterns of unexpected in-hospital deaths: a root cause analysis. Patient Saf Surg. 2011;5(1):3.],[ANCHOR=],[LINK=])
