Abstract
An oximeter sensor with an expandable element for positioning the sensor against the fetus. The expandable element is positioned to be removed from at least one of the emitter and detector so that the portion of the sensor adjacent the emitter or detector is not pressed unduly by the expandable element to exsanguinate the tissue. A constant pressure differential between a pressure of the expandable element and an amniotic pressure may be maintained.
