Accurate and precise management of blood gas parameters during cardiopulmonary bypass (CPB) is crucial to patient care and outcome. This study compares the data provided by Livanova B-Capta, Terumo CDI500, and Spectrum Medical M4 with the results from a gold standard blood gas analyzer to test accuracy.
All three continuous blood gas monitoring (CBGM) devices were used simultaneously during CPB on one dedicated HLM. Arterial and venous blood samples of 40 adult patients who underwent elective cardiac surgery with CPB were taken from the CPB circuit.
Pre- and post-alignment deviation in percentages are compared with CLIA guidelines. B-Capta data reveals that the deviation pre-alignment is small and within the CLIA threshold for all parameters. Pre-alignment data for CDI 500 is within CLIA threshold for SvO2 and PaO2. The pre-alignment data for the M4 exceeds the CLIA thresholds for all parameters. Post-alignment data for B-Capta and CDI 500 reveals an accurate agreement for Hb and Hct and strong agreement for PaO2. All values for B-Capta and CDI 500 are within CLIA threshold values except for SvO2. Post-alignment the M4 exceeded the CLIA threshold value only for PaO2.
B-Capta is the only CBGM device that operates within the CLIA guidelines and is in agreement with laboratory values prior to alignment.
在体外循环 (CPB) 期间准确和精确地管理血气参数对于患者的护理和结果至关重要。本研究比较了 Livanova B-Capta、Terumo CDI500 和 Spectrum Medical M4 提供的数据与金标准血气分析仪的结果，以测试准确性。
在 CPB 期间，所有三种连续血气监测 (CBGM) 设备都在一个专用的 HLM 上同时使用。从 CPB 回路中采集了 40 名接受 CPB 择期心脏手术的成年患者的动脉和静脉血样本。
与 CLIA 指南相比，比较了预校正和后校正的百分比偏差。B-Capta 数据显示，所有参数的预校正偏差都很小，且都在 CLIA 阈值范围内。CDI 500 的预校正数据对于 SvO2 和 PaO2 在 CLIA 阈值范围内。M4 的预校正数据超过了所有参数的 CLIA 阈值。B-Capta 和 CDI 500 的后校正数据显示 Hb 和 Hct 的准确性一致，PaO2 的一致性较强。B-Capta 和 CDI 500 的所有值都在 CLIA 阈值范围内，除了 SvO2。M4 仅在 PaO2 方面超过了 CLIA 阈值。
B-Capta 是唯一在 CLIA 指南范围内运行并与校正前实验室值一致的 CBGM 设备。
