7.7 Contact Impedance Indicator
The contact impedance indicator is used to indicate the impedance between the patient and electrode pads/
external paddles in the Manual Defib mode and AED mode, as shown below:
The display of the contact impedance indicator is switched off by default. To switch it on, set [ Contact
Impedance Indicator ] to [ On ] in the [ Manual Defib Setup ] menu through the Configuration Main menu.
The following table lists the indicator status of the measured impedance and the corresponding actions:
NOTE
•
It is recommended to perform the defibrillation on a patient when the contact impedance indicator
is illuminated in green. If the contact impedance indicator is illuminated in yellow, it also can be
used for the defibrillation. However, the expected effects may not be achieved in this condition.
Contact Impedance
Indicator Description Corrective Actions
indicates the patient contact is good, the
impedance is suitable for the defibrillation. /
(illuminated in green)
indicates the patient contact is not good,
the impedance is slightly higher for the
defibrillation. Firmly attach the electrode pads or external
paddles to the patient. or adjust the
placements of electrode pads or external
paddles until the indicator is illuminated in
green.
If the indicator is still illuminated in yellow, it
also can be used for the defibrillation. However,
the expected effects may not be achieved in
this condition.
(illuminated in yellow)
indicates the patient contact is very poor,
or there is a short circuit between electrode
pads or external paddles.The impedance is
completely not suitable for the
defibrillation. Firmly attach the electrode pads or external
paddles to the patient. or adjust the
placements of electrode pads or external
paddles until the indicator is illuminated in
green or yellow.
(illuminated in red)
indicates the ECG cable or therapy cable
falls off. Check that the ECG cable or therapy cable is
properly connected to the equipment.
