Troubleshooting Most Common Alarms

CAVITY ASSESSMENT ALARM

If the cavity integrity assessment fails, a screen will display “Cavity
Assessment Failure” with an abridged version of the troubleshooting tips
below . The cause of the cavity integrity assessment (CIA) failure is the
inability to pressurize the cavity . It

may be caused by:

1 . Device leak: Ensure that the suction line desiccant filter has been

installed . Check all tubing connections to ensure that they are tightly
connected .

2 . Leak at the external os of the cervix: Look for visible bubbles or a

“hissing” sound at the external os of the cervix .

Use the tab on the cervical collar to advance the cervical collar

towards the external os of the cervix to ensure there is a tight seal .
Perform the CIA test again . If the CIA test fails again, use a second
tenaculum to grasp the cervix around the sheath of the NovaSure
disposable device . Perform the CIA test again .

3 . Uterine perforation:

If a perforation is suspected, the procedure

should be terminated immediately .

NOTE:

leakage may occur at the external cervical os due to the

presence of an over-dilated cervix . Visible bubbles or the “hissing”
sound of escaping gas may accompany CO

leakage under either of

these conditions .

NOTE:

When following the troubleshooting steps on the Model 10

RFC, press the “?” button on the screen and use the scroll buttons
on the right for more information . To get back to the main screen
from the additional troubleshooting tips, press the “X” in the top
right corner of the screen .

If the cavity integrity assessment fails after reasonable attempts
to implement the troubleshooting procedure (step 2 .36), abort the
procedure .

VACUUM ALARM

The Vacuum alarm occurs when the vacuum level is outside its specified
range . This can occur as a result of one or more of the following:
• An over-dilated cervix;
• Poor contact between the cervical collar and the external cervical os;
• The vacuum relief valve is in the closed position;
• An obstruction in the disposable device filter(s) (two) or desiccant; or
• An obstruction within the disposable device .
If the Vacuum check fails, a screen will display “Vacuum Failure” with an
abridged version of the following troubleshooting tips:
• Gently press a 2-3 .5 mm uterine dilator or sound inside the vacuum

relief valve

• Check the cervical collar position, and reposition if necessary . Use the

tab on the cervical collar to advance the cervical collar towards the
external os of the cervix to ensure there is a tight seal . Verify that air is
not being drawn through the cervix by a loose fit between the cervical
collar and the entrance to the cervical canal . If air is being drawn in
through the cervical canal, try to reposition the cervical collar and
disposable device shaft to prevent air ingress .

• Ensure the suction canister on the disposable device is vertical and the

device tubing is not draped over the patient’s leg .

• Check all tubing connections to ensure that they are tightly connected .

Check the push-on tubing connectors at the desiccant tube . Replace
the desiccant if it is pink . Ensure that the filter located near the
disposable connection on the vacuum feedback line is tightened .

• Reattempt ablation .
If the “Vacuum Failure” screen displays again:
• Disconnect the disposable device from the RF controller .
• Remove the disposable device and replace with a new disposable

device .

• Reattempt the ablation with the new device .
