CO2 Insufflation

CO2 Insufflator Systems & Accessories

Using a CO2 insufflator system versus room air for gastrointestinal endoscopy is becoming standard practice. Not only does CO2 insufflation effectively distend the working area for better visibility and access to the inside lining of the digestive tract, it can also help minimize patient discomfort. Find endoscopic insufflators, insufflation systems, tubing sets, and accessories for your suite from STERIS | US Endoscopy.


Clinical Benefits of CO2 Insufflation for Endoscopy

Room air has traditionally been used to distend the GI tract during endoscopic procedures. However, inserting room air into a patient’s GI tract may cause discomfort, pain, and bloating. Using a CO2 Insufflator along with electrosurgical devices during endoscopic procedures can have a positive impact on Clinician’s differential diagnosis.1



  • CO2 is a non-flammable gas that can be used safely while performing electrocautery1
  • CO2 insufflation appears to be well-tolerated, even in patients with underlying pulmonary disease. It doesn’t seem to induce higher rates of respiratory depression or excessive CO2 retention compared with insufflation with ambient room air1

Patient Comfort

  • CO2 is absorbed from the GI tract approximately 160 times faster than nitrogen, the major gaseous ingredient of ambient air. It’s passively absorbed into the blood stream through the mucosal lining, and eventually exhaled through the lungs1
  • Compared with room air insufflation, CO2 insufflation during colonoscopy causes lower postprocedural pain and bowel distention2

Clinical Advantage

  • CO2 insufflation offers clear benefits to patients undergoing advanced endoscopic procedures, lengthy endoscopy procedures, and unsedated procedures1
  • CO2 insufflation is associated with higher serrated polyp detection rates (SPDR) compared to room air insufflation during screening colonoscopy, which could be characterized by improved polyp detection by optimizing bowel insufflation3

CO2EFFICIENT Endoscopic Insufflator

CO2EFFICIENT® Endoscopic Insufflator


Features proprietary “intelligent” software that reduces CO2 flow when it senses insufflation isn’t needed to conserve CO2 supply.

  • Saves CO2 with the patented flow management system
  • Uses standard medical-grade (USP) “D” or “E” size CO2 cylinders
  • Display indicates the total CO2 volume delivered during the procedure


CO2MPACT Endoscopic Insufflator System

CO2MPACT Endoscopic Insufflator® System


Accepts a central supply of CO2, making it a lower-cost option for insufflation.

  • Accepts a tank or central supply of CO2
  • Variable flow rate settings for different endoscopic procedures
  • 30-/60-/90-minute timer stops flow to conserve CO2 supply

CO2 Tubing Sets

CO2 Tubing Sets


These in-line and water bottle cap tubing sets are compatible with Olympus, Pentax, and Fujifilm endoscopes, and feature a hydrophobic filter and pinch clamps to help protect the CO2 insufflator from fluid invasion.


gi4000 Electrosurgical Unit, Probes & Accessories

The gi4000 electrosurgical unit is a great companion for your CO2 insufflator. Designed specifically for flexible endoscopy, the gi4000 electrosurgical unit has Argon, Monopolar, Bipolar, and Lavage functions built into one, compact unit. You’ll also find all the complementary probes, connectors, canisters, and tubing you need to support the use of the insufflator systems from STERIS | US Endoscopy.

Endoscopy Irrigation Pump, Tubing & Scope Connectors

During endoscopy procedures, use our endoscopy irrigation pump, 24-hour tubing and single-patient use scope connectors to easily adjust flow rate and keep it consistent based on the type of procedure.
