Yellow PSS Indicator Light
A
YELLOW
PSS indicator light is displayed when a Non-Sensing/Non-Split dispersive
electrode is connected to the gi4000 ESU. When the PSS light is
YELLOW
, the operator is
prompted to proceed with additional caution as all safety features of the PSS are not active
with Non-Sensing/Non-Split dispersive electrodes.
Dispersive Electrode Type
Action
Non-Sensing / Non-Split
gi4000 ESU is ready for use. Continuously monitor dispersive
electrode application site.
Green PSS Indicator Light
A
GREEN
PSS indicator light is displayed when a Sensing/Split dispersive electrode is both
connected to the gi4000 ESU and to the patient properly. Impedance parameters indicate that
RF electrical energy may be delivered.
Dispersive Electrode Type
Action
Sensing / Split
gi4000 ESU is ready for use.
CAUTION: Non-Sensing Pad Hazard.
The gi4000 ESU Pad Safe System (PSS)
will function with contact quality monitoring (CQM) Sensing/Split dispersive
electrodes or Non-Sensing/Non-Split dispersive electrodes. Other dispersive
electrode products may result in patient or user injury and/or product damage.
→
In order for all safety aspects of the gi4000 Pad Safe System (PSS) to
operate, Sensing/Split dispersive electrodes must be used. Non-
Sensing/Non-Split dispersive electrodes are acceptable if used with
proper user care.
→
The PSS will not identify loss of safe contact between the Non-
Sensing/Non-Split dispersive electrode and the patient, thereby failing to
provide an audible alarm which may result in patient or user injury or
product damage.
→
Disposable dispersive electrodes with a Sensing/Split contact surface
allow the gi4000 ESU to monitor the skin contact quality of the electrode
connection. The dual pad design has a small monitoring current that
flows from one side of the electrode over the patient to the other side of
the pad. STERIS Endoscopy recommends the use of Sensing/Split
dispersive electrodes for use with the gi4000 ESU.
