For the last remaining electrode attached to the long flexible cable, identify the small area of skin
to prepare, so that the center of this reference electrode will be positioned on the midline,
approximately 6 cm (2.4 in) above the rim of the symphysis pubis.
For patients with a displaced umbilicus, very obese patients, or patients with a large
panniculus:
Place the electrode on top of the panniculus approximating to the point 6 cm (2.4 in) vertically
from the symphysis pubis. If during monitoring the aFHR signal quality is poor, reposition the
electrode lower down on the abdomen to maximize the FHR signal, and consider placing the
electrode under the panniculus just below the turn.
13 Prepare the skin like for the first four electrodes.
14 Remove the protective cover from the electrode. Then place the electrode on the prepared skin
and press it down firmly, but avoid pressing the central gel area of electrode.
15 Assign a CL F&M Pod at the base station as described in “CL Pod Assignment” on page 99.
16 Place the CL F&M Pod on the electrode patch.
