How the CO2 Endoscopic Insufflator Works

24 January 2024

The use of carbon dioxide (CO2) for insufflation in medical procedures has emerged as a practical consideration with potential advantages. Unlike traditional methods that often involve the use of room air, the transition to CO2 introduces considerations related to patient outcomes, procedural efficacy, and safety.


Mechanism of the CO2 Endoscopic Insufflator


The CO2 endoscopic insufflator operates based on a closed-loop system, where the insufflated gas is carefully regulated to maintain optimal pressure and flow. The key components and working principles include:


Insufflation Pump:

The insufflation pump is a central component responsible for delivering the CO2 gas into the gastrointestinal tract. It precisely controls the flow rate and pressure, ensuring a consistent and controlled insufflation process.


Pressure Sensors:

Integrated pressure sensors constantly monitor the intra-abdominal pressure during the procedure. These sensors provide real-time feedback to the insufflation pump, allowing for immediate adjustments to maintain the desired pressure levels.


Gas Source and Filters:

The CO2 gas is sourced from a cylinder and passes through filters to ensure purity. The filtration process removes any impurities, making the insufflation gas safe and suitable for medical use.


Waste Gas Management:

A waste gas management system ensures that excess gas, as well as any expelled gases during the procedure, is safely evacuated. This system contributes to maintaining a controlled environment within the endoscopy suite.
