Chapter 5 Operation
This chapter explains the workflow of endoscopic observation using the endoscopic CO
2
regulation
unit.
The operator of the endoscopic CO
2
regulation unit must be a physician or medical personnel under
the supervision of a physician and must have received sufficient training in clinical endoscopic
technique. This manual, therefore, does not explain or discuss clinical endoscopic procedures. It only
describes basic operation and precautions related to the operation of the endoscopic CO
2
regulation
unit.
When using the lens cleaning sheath, follow the instructions given in the manual for the lens cleaning
sheath.
WARNING
•The CO
2
gas is normally emitted through the small hole in the endoscope’s
air/water valve. Persons in the operating room may be affected if the CO
2
concentration in the operating room increases. Be sure to ensure ventilation of the
room.
• If an irregularity is observed or the gas flow indicator illuminates red, immediately
stop using the endoscopic CO
2
regulation unit and take the following actions:
− Close the gas cylinder valve.
− Withdraw the endoscope from the patient slowly as described in the
endoscope’s instruction manual.
• During use, always stop the device like light source from supplying air. If “Stop” is
not selected, a mixture of air and CO
2
may be supplied into the patient body.
• After an examination is completed, turn OFF the endoscopic CO
2
regulation unit. If
the unit is not turned OFF after an examination, the unit may continue to supply gas
when the gas supply button is pressed by mistake. In such a case, the CO
2
gas
cylinder may be emptied, and the ambient CO
2
concentration may increase.
