2.1 INDICATION AND CONTRAINDICATIONS
Indications for Use: The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR is
designed to use CO2 as a distention media in the gastrointestinal tract when used in
conjunction with a gastrointestinal endoscope.
Contraindications for Use:
The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR should be used only for an
endoscopic procedure when insufflation of the gastrointestinal tract is necessary to
support navigation of the endoscope and perform any evaluation procedures through
the endoscope, and should therefore not be used for any other treatments. It should
only be used under the direct guidance of a physician experienced in Gastrointestinal
Endoscopy procedures.
This device is contraindicated for hysteroscopic or laparoscopic insufflation, i.e., it
must not be used for intrauterine distension.
This device is contraindicated for CT Colonography.
2.2 SAFETY FEATURES
The following features help to ensure safe operation of the machine:
FLOW STOP/RUN button: Upon turning power on, gas flow is not initiated until the
FLOW STOP/RUN button is pressed.
An initial pressure relief will occur at 375 mm Hg and a redundant pressure relief
will occur at 400 mm Hg.
An audible alert will sound when the CO2gas supply tank pressure is low.
An audible alert (a single chirp) will sound when the flow of CO2is automatically
stopped by the device.

CO2EFFICIENT ENDOSCOPIC INSUFFLATOR Operator’s Manual
Page 5
Section 3.0 THEORY OF OPERATION
The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR operates by administering
CO2at a maximum flow rate of 3 LPM, and then monitoring the endoscopic
pressure. A mode of operation is selected by the operator, by using a switch found on
the front panel to select from Free Flow Mode and Managed Flow Mode. It is used
to change the rate that the flow is delivered to the endoscopic system. When the
switch is set to Free Flow Mode, the unit will deliver CO2at 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 CO2.
When the switch is set to Managed Flow Mode, the system will be delivering CO2in
a more efficient manner. This mode reduces the amount of CO2that 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 CO2at a flow rate of 3
liters per minute.
The user will need to place the system into RUN mode in order for it to deliver the
CO2to the endoscopic system.
The CO2EFFICIENT ENDOSCOPIC INSUFFLATOR has a Pressure Relief Valve
set at 375 mm Hg and an independent redundant Pressure Relief Valve pre-set to 400
mm Hg. Both pressure relief safety devices are active whether the
FLOW STOP/RUN is on or off.

Section 6.0 FRONT PANEL CONTROLS
NOTE: The appearance of your CO2EFFICIENT ENDOSCOPIC INSUFFLATOR may differ slightly
from the units shown in the illustrations and photographs. (Example: buttons may be round or square).
[1] GAS SUPPLY INDICATOR
Three colors of LED’s to indicate the relative amount of gas available in a
“D”or “E”CO2 supply tank.
[2] VOLUME LITERS DISPLAY
Indicates the total amount of gas used since last reset.
[3] VOLUME RESET
Clears the volume display to zero.
[4] FLOW STOP/RUN
Depression starts flow and button will illuminate. CO2will flow in one of two
modes set by the switch. The pressure response characteristics at which CO2is
delivered to distend the gastrointestinal tract is a function of the clinician and
how this clinician uses CO2to distend the gastrointestinal tract during a
procedure. In Managed Flow Mode, the control system will automatically
transition between the high flow rate and low flow rate as required during the
procedure to compensate for external variables.
To prevent wasting gas in the Free Flow mode, when the FLOW STOP/RUN
button is pressed initially and after 150 Liters of CO2is continuously delivered,
the unit automatically returns to STOP mode. An audible alert, in the form of a
single chirp, will sound when the unit automatically returns to STOP mode.
Thereafter, subsequent presses of the FLOW STOP/RUN button will resume the
delivery of CO2for an additional 150 Liters before automatically returning to
STOP mode. To prevent wasting gas in the Managed Flow mode, when the
FLOW STOP/RUN button is pressed initially and no changes in pressure have

CO2EFFICIENT ENDOSCOPIC INSUFFLATOR Operator’s Manual
Page 11
been detected for 10 minutes, the unit automatically returns to STOP mode. An
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 CO2.
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 CO2at 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 CO2.
When the switch is set to Managed Flow Mode, the system will be delivering
CO2in an more efficient manner. This mode reduces the amount of CO2that 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 CO2at a flow rate of 3 liters per minute.

1. After power is applied to the unit, verify that the front panel lights are enabled.
2. To verify that flow control is functioning properly, depress the FLOW
STOP/RUN button. When pressed, the light in the switch should light, and gas
may be heard exiting from the unit. If gas does not begin flowing, verify that the
CO2supply tank valve is in the open position (see section 10.1, Power On and
Gas Supply Indicator).
3. To prevent wasting gas in the Free Flow mode, when the FLOW STOP/RUN
button is pressed initially and after 150 Liters of CO2is continuously delivered,
the unit automatically returns to STOP mode. Thereafter, subsequent presses of
the FLOW STOP/RUN button will resume the delivery of CO2for an additional
150 Liters before automatically returning to STOP mode. To prevent wasting gas
in the Managed Flow mode, when the FLOW STOP/RUN button is pressed
initially and no changes in pressure have been detected for 10 minutes, 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.
4. If the unit does not perform properly, do not use. Inspect the unit using the
