FHR Gaps Troubleshooting Guide POSSIBLE CAUSE ACTION & SOLUTION1 1 l Return patient to bed l Consider using a maternity belt to support pannus during ambulation or upright position 2.4"/6cm HELP/TIP a) Allow 10-15 minutes of monitoring before starting ambulation. 1"/2-3cm 1"/2-3cm b) The patient should not be encouraged to ambulate unless the FHR trace is good and the signal indicator on the Novii Interface shows 2.4"/6cm 3 green squares. 2.4"/6cm Signal 1"/2-3cm The patient is ambulating l Use a pillow behind back or head 2.4"/6cm 2 to make patient more comfortable l Return patient to a position where 1"/2-3cm Novii worked well 1"/2-3cm l Encourage patient to lie on left or right l If patient on side, support abdomen with 1"/2-3cm a pillow/rolled blanket to re-position abdomen so that the Patch is centred SKIN PREP Patient position/posture over the uterus SKIN PREPARATION GOOD SKIN PREPARATION GOODREPEAT SK REPEAT SKIN PREP REPEAT SKIN PREP REPEAT SK 3 l Check electrodes and move or stick back down REPEAT SKIN PREP DO NOT BY REPEAT SKIN PREP DO NOT BYPASSGOOD SKIN DOPREPARATION l Re-position Patch or electrode to avoid the skin problem NOT BYPASS REPEAT SKIN PREP HELP/TIP REPEAT SKIN PREP a) The Interface will alert user with a visual message, but only when electrode isDOfully NOT detached. BYPASS 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. Electrode ‘detached’ or makes poor contact with skin 4 FHR l Check Interface for help message FHR FHR MHR l Interface is off FHR MHR MHR UA HELP/TIP FHR UA UA MHR a) If Interface has lost power Bluetooth pairing with POD is lost. MHR Remove POD from Patch, place in charging bay and start new monitoring UA episode when power is returned. UA 1"/2-3cm b) Interface does not have a battery back-up. 2.4"/6cm Lost MHR and UA l Start-Screen is displayed as well as FHR HELP/TIP POD has switched off – remove POD from Patch and place in charging well. Start new monitoring session with other POD. 1"/2-3cm l Faulty ‘Y’ Connector - replace 5 l Exfoliate skin under ‘bad’ electrode HELP/TIP SKIN PREPARATION GOOD REPEAT SKIN PREP a) Peel the X electrode back, remove excess gel from skin and finish with alcohol wipe. REPEAT SKIN PREP Wait until skin is dry then exfoliate skin and reapply electrode. DO NOT BYPASS b) May need to use micropore tape to hold in place. l Restart the monitoring session if location of ‘bad’ electrode not known HELP/TIP Bypassed red X on Remove POD from Patch, place in charging bay and start new monitoring episode. electrode/skin checkscreen

Wait until skin is dry then exfoliate skin again and reapply electrode in correct position. 2.4"/6cm b) May need to use micropore tape to hold in place.

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. 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. 107-PT-008-USRev1
