l Return patient to bed
l Consider using a maternity belt to support pannus during
ambulation or upright position
a) Allow 1015 minutes of monitoring before starting ambulation.
b) The patient should not be encouraged to ambulate unless the FHR
trace is good and the signal indicator on the Novii Interface shows
3 green squares.
l Use a pillow behind back or head
to make patient more comfortable
l Return patient to a position where
Novii worked well
l Encourage patient to lie on left or right
l If patient on side, support abdomen with
a pillow/rolled blanket to re-position
abdomen so that the Patch is centred
over the uterus
l Check electrodes and move or stick back down
l Re-position Patch or electrode to avoid the skin problem
a) The Interface will alert user with a visual message, but only when electrode is fully detached.
b) Check electrodes after a shower, clinical procedure, ambulation or position change.
c) Electrode(s) should not be placed over a skin lesion, skin fold, umbilicus, stretch mark,
pronounced linea nigra.
d) If necessary use a strip of micropore tape to prevent electrode lifting or detachment.
l Check Interface for help message
l Interface is o
l Exfoliate skin under ‘bad’ electrode
l Restart the monitoring session if location of ‘bad’ electrode not known

a) If Interface has lost power Bluetooth pairing with POD is lost.
Remove POD from Patch, place in charging bay and start new monitoring
episode when power is returned.
b) Interface does not have a battery back-up.
l Start-Screen is displayed
POD has switched o – remove POD from Patch and place in charging well.
Start new monitoring session with other POD.
a) Peel the X electrode back, remove excess gel from skin and inish with alcohol wipe.
Wait until skin is dry then exfoliate skin and reapply electrode.
b) May need to use micropore tape to hold in place.
Remove POD from Patch, place in charging bay and start new monitoring episode.

l Re-position electrode
a) Peel the electrode back, remove excess gel from skin and inish with alcohol wipe.
Wait until skin is dry then exfoliate skin again and reapply electrode in correct position.
b) May need to use micropore tape to hold in place.
l Remove electrode and place it lower or higher on the abdomen
l Alternatively place electrode just below the point where
the surface curves back on itself ensuring that the electrode
is not folded
l Plug in US transducer for short
FHR ‘illing’ and reassurance

monitoring modality
10 Second Trace Example
Notes:
This troubleshooting guide assumes that the patient is supine or semi-supine during Patch placement and Novii set-up.
1. CAUTION: any intervention will take 10 seconds before its impact will be seen on the trace.
2. The user is familiar with the placement of Patch and lower mid-line electrode in high BMI patients with a pannus.

6 Second Trace Example
High/Low UA Sensitivity Explained
Selecting UA Low sensitivity from the Novii display will decrease the UA trace amplitude, suppressing unwanted low amplitude
UA, but it will also reduce the contraction duration. There will be no change to the location of the peak.
Low amplitude UA is considered to be due to artefact from fetal/maternal movement and unsynchronised myometrial activity.
Using US FHR with Novii UA could
make a late deceleration appear early
Novii FHR/MHR/UA are synchronised
but all trace 5mm (10 sec) behind US FHR trace.
Using TOCO UA with Novii FHR could
make an early deceleration appear late
Novii FHR/MHR/UA are synchronised
but all trace 3 mm (6 sec) behind TOCO UA trace.
