Oxygen may affect glucose meter and reference analyzer measurements. We evaluated the effects of changes in blood oxygen tension (Po2) on Accu-Chek Comfort Curve (Roche Diagnostics, Indianapolis, IN), Precision G, (Abbott Laboratories, Bedford, MA) and One Touch II (Lifescan, Milpitas, CA) glucose meter measurements, and on Yellow Springs Instruments (YSI) (Yellow Springs, OH) reference analyzer measurements. Venous blood drawn from healthy volunteers was adjusted to three glucose levels of 80, 200, and 400 mg/dL, each tonometered with six different Po2 levels (40, 80, 160, 240, 320, and 400 torr). To quantitate oxygen effects on reference analyzer measurements, glucose differences between test sample (Po2 changed) and control (Po2 80 torr) were calculated (YSItest-YSIcontrol). The threshold for determination of oxygen effects was +/-2 SD, where 2 SD was fro
氧气可能会影响血糖仪和参考分析仪的测量结果。我们评估了血氧张力（Po2）变化对拜安易血糖仪（罗氏诊断公司，印第安纳波利斯，印第安纳州）、Precision G血糖仪（雅培实验室，贝德福德，马萨诸塞州）和One Touch II血糖仪（强生公司生命扫描部，米尔皮塔斯，加利福尼亚州）测量结果的影响，以及对美国黄春菊仪器公司（YSI）（黄泉，俄亥俄州）参考分析仪测量结果的影响。从健康志愿者采集的静脉血被调整到80、200和400mg/dL三个血糖水平，每个水平用六种不同的Po2水平（40、80、160、240、320和400托）进行血气平衡调节。为了定量氧气对参考分析仪测量结果的影响，计算了测试样品（Po2改变）和对照（Po₂ 80托）之间的血糖差异（YSI测试 - YSI对照）。确定氧气影响的阈值为±2标准差，其中2标准差来自于……（原文此处不完整）
