Abstract

We have designed a simple, inexpensive, easy-to-build and operate apparatus for measuring blood oxygen content. The galvanic oxygen cell (fuel cell) requires as little as 1 microliter of blood and has a measuring time of 1-3 min. It is well suited for measuring oxygen content in fluids low in oxygen inasmuch as the sensitivity of the instrument is variable. Either air or water (at a known temperature and oxygen tension) can be used for calibration. No significant differences in blood oxygen content measured with our cell or the Van Slyke manometric method were found.

摘要

我们设计了一种简单、廉价、易于构建和操作的用于测量血氧含量的仪器。原电池式氧传感器（燃料电池）所需血量低至1微升，测量时间为1 - 3分钟。由于该仪器的灵敏度可变，它非常适合测量低氧流体中的氧含量。空气或水（在已知温度和氧分压下）均可用于校准。用我们的传感器测量的血氧含量与范斯莱克测压法测量的结果没有显著差异。
