New method for removing CO2 in anesthesia circuits
A New and Innovative Method for CO2 Removal in Anesthetic Circuits:
This study is testing a new CO2 filter for anesthesia machines to see if it safely removes carbon dioxide while keeping anesthetic gases intact, making it better for patients and the environment.

What this trial studies
This study evaluates a novel CO2 filter called memsorb, developed by DMF Medical, which utilizes advanced medical membrane technology to filter CO2 from anesthetic circuits. Unlike traditional chemical absorbers, memsorb selectively allows CO2 to escape while retaining anesthetic vapors, addressing safety concerns and environmental impacts associated with chemical granulates. The device is designed to fit seamlessly into existing anesthetic systems, making it a practical alternative for healthcare providers. The trial aims to assess the effectiveness and safety of this innovative approach in a clinical setting.
Who should consider this trial
Good fit: Ideal candidates include English-speaking patients classified as low to medium risk by the American Society of Anesthesiologists.
Not a fit: Patients who are pregnant, have high-risk classifications, or suffer from severe respiratory diseases will not benefit from this study.
Why it matters
Potential benefit: If successful, this technology could enhance patient safety and reduce environmental waste associated with anesthesia.
How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, indicating that this technology may be novel and untested in clinical settings.
