Nevertheless, it is sometimes bothersome to visually measure respiratory rate over 1\u2009min. Respiratory rate measurement using a mobile phone application \u201cRRate\u201d has been reported to be accurate and completed in a short time. However, it has only been investigated in children. The aim of this study was to validate the \u201cRRate\u201d compared with the 1\u2010min method in adult patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This was a cross\u2010sectional study in the setting of a nursing school. Videos of the movement of the thorax during respiration of adult patients were made. Nursing students watched these videos and measured respiratory rate with each method. Bland\u2013Altman analysis was used to calculate bias and limits of agreement.

When compared to the reference measurement, the one measured using \u201cRRate\u201d and the one measured over 1\u2009min showed a bias of 0.40 breaths per minute and 0.65 breaths per minute, limits of agreement of \u22122.86 to 3.67 breaths per minute and \u22122.11 to 3.41 breaths per minute, respectively. The mean measurement time for \u201cRRate\u201d was 22.8\u00a0s (95% CI 13.9\u201336.6), which was significantly shorter than the 65.8\u00a0s (95% CI 61.0\u201373.2) for the measurement over
