Two electrodes placed at the tip of catheters for in vivo determinations of PCO2 and PO2 respectively, were tested in dogs. Results were satisfactory when compared to a highly accurate reference method, correlation coefficients were close to 1 (P less than 10(-9)). Means of the differences were respectively --1.74 +/- 1.14 toor for the PO2 probe (P less than 0.01) and --1.62 +/- 0.72 torr for the PCO2 sensor (P less than 0.0001). While no drift was detected in the PCO2 electrode, that of the PO2 was significant but negligible compared to the variability of measurements. Thus, for PCO2 values between 20 and 85 torr, and PO2 values between 20 and 140 torr, in vivo monitoring is sufficiently reliable for clinical use.
分别用于体内测定PCO₂和PO₂的两根置于导管尖端的电极在狗身上进行了测试。与一种高度精确的参考方法相比，结果令人满意，相关系数接近1（P小于10⁻⁹）。PO₂探头差异的均值分别为-1.74±1.14托（P小于0.01），PCO₂传感器差异的均值为-1.62±0.72托（P小于0.0001）。虽然在PCO₂电极中未检测到漂移，但PO₂电极的漂移是显著的，但与测量的变异性相比可忽略不计。因此，对于20至85托之间的PCO₂值以及20至140托之间的PO₂值，体内监测在临床上使用足够可靠。
