Low UA
• Check for electrode disconnection and secure back down. If electrode #3 on patient’s
left has problem then UA will be lost/flat. OK to use medical tape to hold in place.
HELP/TIP
The Interface will alert user with a visual message, only when electrode is fully detached
• Check the Interface UA sensitivity setting and ensure that the High UA setting has
been selected.
• Zero UA before starting Novii monitoring. Do not zero during monitoring. Although UA
Reference may be done between contractions, using palpation to confirm, it is best
practice to return the Pod to the Interface, and then Zero UA.
• Check that UA interface cable between Novii interface and fetal monitor is connected
correctly. Wiggle cable connector to ensure the monitor input connector is not loose
or defective. Run a Novii Test to confirm.
• Was UA amplitude high, but now low? If so, has patient changed position?
Check patch has not moved away from uterus (i.e high BMI, loose skin).
If needed, place pillow under abdomen to support patch back over uterus.
• Confirm Patch is centered on uterus and the center of bottom electrode is 6cm above
top rim of pubic bone. Electrode #3 is most important for obtaining good UA, thus
poor positioning of this electrode may result in low UA. Reposition Patch if needed.
