An intrauterine pulse oximetry apparatus and method are provided to measure foetal blood oxygen saturation at sites in a preferred region on the foetus. The sensor (103) of the apparatus (100) is attached to a stiff cable (102) which can be inserted into the uterus past the presenting part and transcervical region of the foetus. The cable may have visual and tactile markings (107, 108) by which the user, without seeing or feeling the sensor, can guide it to an appropriate site on the foetus. <IMAGE> |
