Primary outcomePrimary: End-tidal CO2 Concentration (%) — 5.069; 5.096 % end-tidal CO2
Summary
The drawbacks of chemical CO2 absorbers include the production of compounds harmful to patients that also lead into increased cost and environmental impact, as well as the daily disposal of compound special waste. Sustainable management of general anesthesia is a growing concern. Continually diluting anesthetic circuits, and the disposal of chemical granulate are serious environmental problems.
