4 Theory of Operation:
The MEDIVATORS® ENDO STRATUS® CO2 Insufflator works by regulating CO2 from a tank
source to a preset pressure and then controlling the output of CO2 to a GI endoscope system for
ultimate delivery as a distention media in the gastrointestinal tract. The clinician will use the
air/water valve on the GI endoscope and visual feedback of the GI endoscopic system to
manually distend the gastrointestinal tract with CO2.
The ENDO STRATUS CO2 insufflator contains a CO2 warming feature that allows the clinician to
modulate and control delivery of CO2 to the patient that has been warmed to a target temperature
of 37°C with an upper tolerance of +3°C. Warming is achieved as CO2 flows across a heating
element which can be switched on or off by the user, depending on if warming of the CO2 is
desired. The heating of the CO2 is accomplished through an internal 20W heating element with
dual redundant temperature sensors.
The flow rate can be adjusted to low, medium or high settings depending on the desired rate of
insufflation, with flow rates of 1.4 L/min, 2.4 L/min and 3.5 L/min maximum, respectively.
When the unit is turned on, the CO2 flow and heating function are off by default. To initiate gas
flow the user must turn the flow setting knob from the “off” position. The unit will detect gas flow
and will not allow the heater to operate unless gas flow is detected. In addition, there is a low gas
pressure sensor and the unit will indicate when the input CO2 pressure reaches 25 PSI by
illuminating a yellow light on the front panel.
The unit also has an output to power the water bottle warmer. The water bottle heating element
maintains the temperature of the water in a sterile water bottle at 37°C ± 3°C. It is controlled by
dual temperature sensors for redundancy and safety.

tubing to ENDO SMARTCAP® tubing or ENDOGATOR® hybrid tube set. Attach ENDO
SMARTCAP tubing or ENDOGATOR hybrid tube set to the GI endoscope according to the
manufacturer’s instructions.
Water Pre-Warming
1. The ENDO STRATUS® CO2 Insufflator can be used to control the Water Bottle Warmer
system. The warmer system can maintain the temperature of bottles of sterile water at 37°C
(±3°C). However, the system is not intended to raise the temperature of the water; therefore,
pre-warming of the water bottle is required.
2. The water bottle must be pre-warmed with a method such as a fluid warmer if warm water is
desired. Water bottle pre-warming should be performed according to the following instructions:
Place sterile water bottle in a fluid warming oven set to 37°C ± 3°C. Do not exceed this
temperature. If warm water is not desired, turn the water warmer on the pump off and
place a bottle of room temperature sterile water on the water bottle holder.

NOTE: If the water warmer has been enabled and has exceeded the upper temperature set
point limit, the water warmer’s switch indicator light will turn blue and the warmer will
automatically shut off. If the switch indicator light is flashing blue, ensure the Water Warmer
Cable is plugged into the back of the unit. If it is connected and the light is flashing, this may
indicate a problem with the unit. Contact MEDIVATORS Technical Support at 800-4444729.
i
Read and become familiar with all manufacturers’ instructions on warming
ovens and water bottles regarding maximum fluid temperatures. Never exceed
40°C during water pre-warming. Never use a microwave oven to warm a water
bottle, as this could heat the water to a dangerously high temperature or could
result in uneven warming.
CAUTION: The surface of the Water Bottle Warmer may be hot to the touch.
19 Operation
1. After the pre-procedure setup has been completed, flow can be initiated.
2. Turn the Flow Control Knob to the first position. “L” will illuminate for “LOW”. If a higher flow
rate is desired, turn the knob to the next position for “MEDIUM” and one more position for
“HIGH”. “M” will illuminate for “MEDIUM” and “H” will illuminate for “HIGH”. The knob will turn
freely in each direction, and will increase or decrease the flow rate accordingly.
3. If warming of the CO2 is desired, press the button for the CO2 heater. The button will illuminate
green.
4.
If the device is attached to a water bottle warmer, and water warming is desired, press the
button for Water Bottle Warmer. The button will illuminate green.
5. Use the appropriate air/water valve on the GI endoscope and visual feedback of the GI
endoscopic system to manually distend the gastrointestinal tract with CO2.
Shutdown
1. When the procedure is over, turn the Flow Control Knob counter clockwise until all lights are
off, turn off the Water Bottle Warmer (if attached) and turn off the CO2 heater.
