文本中提供了补充数字内容。ICU中的心输出量（CO）测量通常基于侵入性技术，其技术复杂且与临床并发症相关。本研究旨在比较ICU患者中基于无创光电容积描记术的器械与脉搏轮廓心输出量器械获得的CO测量值。观察性、前瞻性、比较性临床试验。单中心综合ICU。根据主治医生的决定，使用脉搏轮廓心输出量装置监测入住普通ICU的患者。使用基于光电体积描记术的胸部贴片装置和脉搏轮廓心输出量平行监测CO，而医疗团队对无创装置获得的值不知情。7例患者（69次测量）被纳入最终分析。热稀释法和光电体积描记法的平均CO分别为7.3 ± 2.0 L/m和7.0 ± 1.5 L/m。Bland-Altman表明，当计算与热稀释法的差异百分比时，光电体积描记法的偏倚为0.3 L/m，95%一致性限（LOA）为-1.6和2.2 L/m，偏倚为2.4%，95% LOA在-25.7%至30.5%之间。通过热稀释法和光电容积描记法获得的值高度相关（r = 0.906）。与通过脉搏轮廓心输出量和热稀释法在ICU患者中获得的数据相比，受试胸部贴片设备提供了较高的CO准确度。这种设备可以在各种临床环境中提供先进的监测能力，而没有侵入性设备的并发症。
Supplemental Digital Content is available in the text. Cardiac output (CO) measurements in the ICU are usually based on invasive techniques, which are technically complex and associated with clinical complications. This study aimed to compare CO measurements obtained from a noninvasive photoplethysmography-based device to a pulse contour cardiac output device in ICU patients. Observational, prospective, comparative clinical trial. Single-center general ICU. Patients admitted to the general ICU monitored using a pulse contour cardiac output device as per the decision of the attending physician. Parallel monitoring of CO using a photoplethysmography-based chest patch device and pulse contour cardiac output while the medical team was blinded to the values obtained by the noninvasive device. Seven patients (69 measurements) were included in the final analysis. Mean CO were 7.3 ± 2.0 L/m and 7.0 ± 1.5 L/m for thermodilution and photoplethysmography, respectively. Bland-Altman showed that the photoplethysmography has a bias of 0.3 L/m with –1.6 and 2.2 L/m 95% limit of agreement (LOA) and a bias of 2.4% with 95% LOA between –25.7% and 30.5% when calculating the percentage of difference from thermodilution. The values obtained by thermodilution and photoplethysmography were highly correlated (r = 0.906). The tested chest patch device offers a high accuracy for CO compared to data obtained by the pulse contour cardiac output and the thermodilution method in ICU patients. Such devices could offer advanced monitoring capabilities in a variety of clinical settings, without the complications of invasive devices.
