  • Insertion type electrode arrangement for continuous pO.sub.2 measurement in living skin tissue
    Patent number: 4893625
    Abstract: It is possible by means of a new spiral electrode arrangement to measure the pO.sub.2 partial pressure of restless moving tissue, for example on a child during labor. At the same time the electrode arrangement allows measurement of the child's heartbeat frequency pattern during labor. By graphically representing both measurement patterns a doctor can determine when he must, for example, accelerate the birth or initiate other clinical measures.
