The performance characteristics of two transcutaneous combined PO2 (tcPO2) and PCO2 (tcPCO2) sensors were compared with single tcPO2 and tcPCO2 electrodes in critically ill patients. The relationship between arterial blood gases (PaO2, PaCO2) and transcutaneous values was linear. Correlation coefficients (r) varied from 0.79 to 0.87 for tcPO2 and 0.92 to tcPCO2. The tcPO2 readings were always lower than PaO2 values, but the tcPCO2, with modified calibration of the electrodes, did not differ significantly from PaCO2. There was no significant difference of clinical importance in the performance of the three monitoring systems.
在危重症患者中,将两种经皮联合氧分压(tcPO2)和二氧化碳分压(tcPCO2)传感器的性能特征与单个tcPO2和tcPCO2电极进行了比较。动脉血气(PaO2、PaCO2)与经皮测量值之间呈线性关系。tcPO2的相关系数(r)在0.79至0.87之间,tcPCO2的相关系数在0.92至[此处原文似乎有误,推测可能是0.92至某个值,暂按原文翻译]之间。tcPO2读数始终低于PaO2值,但经过电极校准修正后的tcPCO2与PaCO2无显著差异。这三种监测系统的性能在临床重要性方面无显著差异。
