Virtual Colonoscopy

PROTOCO2L™

An Essential Component for Successful Virtual Colonoscopy



	Automated CO2 insufflation maintains a constant intraluminal pressure and an optimally distended bowel.



	Even in patients with a redundant sigmoid, as shown here, PROTOCO2L delivers consistent insufflation throughout the length of the colon.

VC RESEARCHERS AGREE: Automated Insufflation Using E-Z-EM's PROTOCO2L Can Yield Equivalent or Even Superior Distention to Manual Insufflation.

Automated CO2 insufflation is much better tolerated than room air. Diffusion of CO2 through the colonic wall is extremely rapid compared with air, diminishing the presence of ileocecal valve reflux.

Average distention was significantly better in the automated CO2 group with only one collapsed segment, versus 17 in the manually insufflated group.

Automated CO2 insufflation demonstrates improved distention compared to manual insufflation, particularly in segments that are prone to collapse.

Advantages to Automated Insufflation with CO2
	Patient Comfort & Safety	Carbon dioxide is readily absorbed and minimizes post-procedure discomfort. Redundant pressure relief valves and automatic flow stop features help protect against over-insufflation.
	Consistent Insufflation	Regulated pressure gently distends the colon and then helps maintain constant, adequate insufflation for the duration of the study.
	Enhanced Productivity	Automated operation helps reduce staff time during the insufflation process.
