BACKGROUND
Capstesia is an app for smartphones that can serve as a simple, accessible and affordable alternative to current advanced hemodynamic monitoring devices. The aim of this paper was to establish the degree of concordance between the Vigileo monitor and the Capstesia app in the measurement of cardiac output in patients undergoing cardiac surgery.
METHODS
A process study was conducted that included 30 patients whose cardiac output was measured simultaneously with the Capstesia app and the Vigileo monitor. The analysis was done using the Lin's concordance correlation coefficient and Student's t - test. A p < 0.05 was considered significant. The information was processed in SPSS v. 22.0.
RESULTS
332 paired samples were taken. The cardiac output values obtained were 4.43 ± 1.37 L/min for the Vigileo monitor and 4.45 ± 1.38 L/min for the Capstesia app. Lin's concordance correlation coefficient yielded a value of 0.966 with a confidence range of 0.958-0.973.
CONCLUSIONS
There is substantial concordance between the cardiac output values yielded by the Vigileo monitor and the Capstesia app in patients undergoing cardiac surgery.
背景
Capstesia是一款适用于智能手机的应用程序，它可以作为当前先进血流动力学监测设备的一种简单、易用且经济实惠的替代方案。本文的目的是确定在心脏手术患者中，Vigileo监测仪与Capstesia应用程序在测量心输出量方面的一致性程度。
方法
进行了一项过程研究，纳入了30例患者，同时使用Capstesia应用程序和Vigileo监测仪测量他们的心输出量。采用Lin一致性相关系数和学生t检验进行分析。p < 0.05被认为具有统计学意义。数据在SPSS v. 22.0中进行处理。
结果
共采集了332对样本。Vigileo监测仪测得的心输出量值为4.43±1.37 L/分钟，Capstesia应用程序测得的值为4.45±1.38 L/分钟。Lin一致性相关系数为0.966，置信区间为0.958 - 0.973。
结论
在心脏手术患者中，Vigileo监测仪和Capstesia应用程序测得的心输出量值具有高度一致性。
