摘要： A zirconia oxygen sensor is disclosed which is especially designed for sensing respiratory gases on a breath-by-breath basis. In order to obtain a sufficiently high response time necessary for breath-by-breath gas analysis, a commercially-available zirconia ceramic element is dimensionally tailored to cooperate with a manifold member such that the volume of the gas being analyzed is extremely small, yet uniformly distributed over an internal surface of the zirconia cell. Cooperating with the zirconia cell and the manifold are a set of spring contacts which perform the dual function of providing an electrical terminal and acting as a gas-type seal when the manifold is compressed against the end of the cell.
