Semi‐implantable needle oxygen electrodes were used for forearm subcutaneous monitoring in human subjects undertaking high intensity cycling and fist clenching exercise. pO2 variations in the range between 40 and100 mm Hg oxygen were seen. Superimposed on these were paradoxical rises in subcutaneous pO2, of up to 100 mm Hg which paralleled the scale of the exercise. This was indicative of increased blood flow through skin. Triton X‐100 incorporated into the sensor polyurethane membranes helped to give faster responses and reduced the possibility of biofouling and drift. The sterilizable system, free from internal electrolyte film appears promising for future clinical monitoring.

使用半植入式针电极对运动过程中皮下组织pO2波动的电化学监测
半植入式针式氧气电极用于进行高强度骑自行车和握紧拳头运动的人类受试者的前臂皮下监测。观察到pO 2在40至100 mm Hg氧气范围内变化。叠加在这些上的是皮下pO 2的反常升高，最高可达100 mm Hg，与锻炼的规模平行。这表明通过皮肤的血流量增加。传感器聚氨酯膜中包含的Triton X-100有助于提供更快的响应并减少了生物积垢和漂移的可能性。不含内部电解质膜的可消毒系统似乎有望用于未来的临床监测。
