l Re-position electrode
a) Peel the electrode back, remove excess gel from skin and inish with alcohol wipe.

ait 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

l Swap back to conventional
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.
