title: Electrochemical aspects of intravascular oxygen transducers.
abstract: The factors which limit the useful lifetime of miniaturized electrochemical oxygen transducers for use in neonatal intensive care are described. These factors arise from the use of the conventional silver-silver chloride reference electrode. Four possible means of improving the useful lifetime are described, namely the use of ion-permeable membranes, guard electrodes, potential-time programmes and nickel(II) hydroxide reference electrodes.
