INTRODUCTION: Intensive Care Medicine is based on continuous timely monitoring of physiological variables to guide modulation of therapy. This monitoring is often invasive, but there is a trend for the adoption of non-invasive devices, already largely used in wards and homecare, to reduce risk of device-associated side effects. The aim of this study was to assess the accuracy of a non-invasive equipment (Corsano Cardiowatch 287-2B) in the assessment of blood pressure, heart rate, temperature and oxygen saturation in critically ill patients admitted to the ICU. METHOD: This prospective cohort study developed in an adult ICU admitting patients for level 3 and 2 of care compared the Corsano Cardiowatch 287-2B with the ICU standard monitoring, namely continuous electrocardiogram, invasive arterial blood pressure through arterial catheter, pulse oximeter and central thermometer. Concordance was assessed using the Bland-Altman test. RESULTS: Nineteen patients were included in the study. The number of time-points included for comparison between the two monitoring strategies were more than 50,000 in pulse and heart rate, around 40,000 in oxygen saturation and body temperature and 1,200 in systolic and diastolic blood pressure. Bias for heart rate and pulse were -1.73 and -0.77, respectively. The limits of agreement were between -14.90 and 11.33, for heart rate, and -14.25 and 12.71, for pulse. Small biases were also estimated for oxygen saturation (0.21), with limits of agreement between -6.97 and 7.39, and body temperature (0.58), with limits between -1.12 and 2.47. Concordance was low for diastolic and systolic blood pressure, with bias of 5.18 and -11.27, respectively. CONCLUSIONS: Corsano Cardiowatch 287-2B reaches good levels of concordance compared to traditional ICU monitoring for heart and pulse rates and may be a valuable solution for their less invasive monitoring, with promising results for future operationalization for oxygen saturation and body temperature. Concordance is low for blood pressure, meaning the device is currently unsuitable for use with that purpose.
引言：重症医学基于对生理变量的持续及时监测来指导治疗调整。这种监测通常具有侵入性，但目前有一种趋势是采用已在病房和家庭护理中广泛使用的非侵入性设备，以降低与设备相关的副作用风险。本研究的目的是评估一种非侵入性设备（科尔萨诺心脏监测仪287 - 2B）在评估入住重症监护病房（ICU）的重症患者血压、心率、体温和血氧饱和度方面的准确性。 方法：这项前瞻性队列研究在一家收治三级和二级护理患者的成人ICU中开展，将科尔萨诺心脏监测仪287 - 2B与ICU标准监测设备进行比较，后者包括连续心电图、通过动脉导管进行的有创动脉血压监测、脉搏血氧仪和中心温度计。使用布兰德 - 奥特曼检验评估一致性。 结果：19名患者纳入研究。两种监测策略之间用于比较的时间点数量，脉搏和心率超过50,000个，血氧饱和度和体温约40,000个，收缩压和舒张压1,200个。心率和脉搏的偏倚分别为 - 1.73和 - 0.77。心率的一致性界限在 - 14.90至11.33之间，脉搏在 - 14.25至12.71之间。血氧饱和度（0.21）和体温（0.58）也存在较小偏倚，血氧饱和度的一致性界限在 - 6.97至7.39之间，体温在 - 1.12至2.47之间。舒张压和收缩压的一致性较低，偏倚分别为5.18和 - 11.27。 结论：与传统的ICU心脏和脉搏率监测相比，科尔萨诺心脏监测仪287 - 2B达到了较好的一致性水平，可能是其侵入性较小监测的一种有价值的解决方案，在未来用于血氧饱和度和体温监测方面有良好前景。血压的一致性较低，意味着该设备目前不适合用于此目的。
