audible alert, in the form of a single chirp, will sound when the unit automatically
returns to STOP mode. However, you can stop the flow using the FLOW
STOP/RUN button while the unit is in RUN mode, as evidenced by the
illuminated FLOW STOP/RUN button.
The user can always depress the FLOW STOP/RUN button during any of these
volume increments to stop delivery of CO
2
.
NOTE:
Flow cannot be initiated if gas bottle pressure is less than 25 psi.
[5] FLOW MODE SELECTION SWITCH
The unit operates in one of two modes.
When the switch is set Free Flow Mode, the unit will deliver CO
2
at a flow rate
of 3 liters per minute continuous. The clinician will use the air/water valve on
the endoscope and visual feedback of the endoscopic system to manually distend
the gastrointestinal tract with CO
2
.
When the switch is set to Managed Flow Mode, the system will be delivering
CO
2
in an more efficient manner. This mode reduces the amount of CO
2
that is
lost through the air/water valve which is normally lost at a rate of 3 liters per
minute. When gas is not used in the endoscopic system to insufflate, the unit will
operate at the Managed Flow rate of 0.25 to 1.0 liter per minute. This transition
to the Managed Flow rate will occur if the unit senses no need for insufflation in
a 2 second time period. When gas is needed to insufflate, the unit will deliver
CO
2
at a flow rate of 3 liters per minute.
[6] GAS OUTPUT CONNECTION TO ENDOSCOPE
Connector for Tubing Set.
[7] POWER SWITCH
