An oximeter probe (5) is introduced through the vaginal canal (4) and applied to the scalp (9) or other readily accessible part of the fetus (1) while still in utero. The fetal oxygenation is monitored during the entire labor and delivery period to obtain instantaneous indications of any peripartum fetal distress. The probe comprises a clamping device which can be easily manipulated within the narrow confines of the partially dilated cervix (3).
