Abstract: A combined spiral EKG electrode and pH probe for use in monitoring a fetus during labor is described. The combined probe includes a spiral wound needle which acts as an EKG electrode and also houses a fiber optic pH probe. Optical fibers and wires from the needle as well as from a reference electrode on the probe assembly are passed back through the cervix and vagina of a woman in order to provide simultaneous information as to both EKG and pH of the fetus during labor.
