Abstract：Objective To study the time consuming and uncontrollable characteristics of regulation of oxygen partial pressure of vein blood required by blood glucose meter comparison experiment, the effective regulation method of oxygen partial pressure of vein
blood blood. Methods Based on the principle of the gas tension method, in a tension balancer under the control of temperature, pressure and humidity, fresh whole blood was balanced with a nitrogen standard oxygen gas standard substance with an oxygen
concentration of 8.99% to prepare an oxygen partial pressure of (65±5) mmHg. After the regulated venous blood sample were verified by a blood gas analyzer and the venous blood samples without any treatment were simultaneously tested on three different
types of blood glucose meters. Results Compared with the venous blood sample without any treatment, the venous blood sample based on the gas tension method can effectively regulate the oxygen partial pressure of the venous blood sample required for the
blood glucose meter comparison experiment, and based on this, the blood oxygen partial pressure reference measurement program have established. Conclusion The gas tension method can effectively overcome the interference of oxygen in the air during the
comparison test of the blood glucose meter and promote blood glucose meter product testing technology upgrade.
