Carbon Dioxide (CO2)

We are the first Gastroenterology Center in the Tri-Cities to use carbon dioxide (CO2), the same gas that surgeons use during some surgeries, to insufflate the GI tract during endoscopic procedures.

To achieve optimal visualization of any part of the GI tract once an endoscope has been inserted, it is necessary to insufflate a gas, which distends the lumen and allows the mucosa (bowel lining) to be examined.  The most common practice is to use ambient atmospheric air, also termed "room air", to insufflate the lumen.  This is a convenient, abundant, and free source of gas.

The huge benefit of using CO2 instead of room air is that it is rapidly absorbed from the bowel (CO2 is absorbed 150 times faster than the nitrogen in room air, and is promptly eliminated via the lungs) which allows the bowel to decompress more rapidly and decreases intra-procedural and post-procedural pain (little-to-none!), sedation medication requirements, procedure time, and recovery time.
