<p>A method and apparatus for monitoring the location of a fetus in a birth canal during labor. The conductors (26, 28) of a fetal monitor probe (2), such as a fetal heartbeat monitor electrode, are marked with calibration means (101-120) corresponding to predetermined distances from a babyward end (20) of the probe (2). The babyward end (20) of the probe (2) is attached to the baby. During labor, the position and progress of the fetus on the birth canal may be inferred by observing the calibration means (101-120) relative to the outer end of the birth canal.</p> |
