Abstract

AIMS

Respiratory rate measurement is one of the core nursing skills for early detection of deterioration of a patient's condition. Nevertheless, it is sometimes bothersome to visually measure respiratory rate over 1 min. Respiratory rate measurement using a mobile phone application "RRate" 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 "RRate" compared with the 1-min method in adult patients.

METHODS

This was a cross-sectional 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-Altman analysis was used to calculate bias and limits of agreement. The times taken for the measurements were compared using a t test.

RESULTS

A total of 59 nursing students participated. When compared to the reference measurement, the one measured using "RRate" and the one measured over 1 min showed a bias of 0.40 breaths per minute and 0.65 breaths per minute, limits of agreement of -2.86 to 3.67 breaths per minute and -2.11 to 3.41 breaths per minute, respectively. The mean measurement time for "RRate" was 22.8 s (95% CI 13.9-36.6), which was significantly shorter than the 65.8 s (95% CI 61.0-73.2) for the measurement over 1 min (p < .001).

CONCLUSIONS

Respiratory rate can be measured accurately in a shorter time using a mobile phone application in adult patients.

摘要

目的

呼吸频率测量是早期发现患者病情恶化的核心护理技能之一。然而，有时肉眼观察 1 分钟以上的呼吸频率会很麻烦。使用手机应用程序“RRate”测量呼吸频率已被报道具有准确性，且测量时间短。然而，该应用程序仅在儿童中进行了研究。本研究的目的是验证“RRate”在成年患者中与 1 分钟测量方法的准确性。

方法

这是一项在护理学校环境下进行的横断面研究。对成年患者呼吸时胸部运动的视频进行拍摄。护理学生观看这些视频，并使用每种方法测量呼吸频率。采用 Bland-Altman 分析计算偏差和一致性界限。使用 t 检验比较测量时间。

结果

共有 59 名护理学生参与了研究。与参考测量值相比，使用“RRate”测量和 1 分钟测量的偏差分别为 0.40 次/分钟和 0.65 次/分钟，一致性界限分别为-2.86 次/分钟至 3.67 次/分钟和-2.11 次/分钟至 3.41 次/分钟。使用“RRate”的平均测量时间为 22.8 秒（95%置信区间 13.9-36.6），明显短于 1 分钟测量的 65.8 秒（95%置信区间 61.0-73.2）（p<0.001）。
