Authors: Jennifer Jouwena, M.D. et al Anesthesiology December 2023. Background CO2 absorbers allow the use of fresh gas flows (FGF) below minute ventilation (V̇E). Models are developed and tested in vitro to quantify their performance with variable CO2 load (V̇CO2), FGF, V̇E, end-tidal CO2 fraction (FETCO2), and the type of workstation used. Methods First principles are used to […]

Although fixed-dose administration is suggested, body weight affects the volume of the central chamber and thus affects the sedation depth that can be achieved by the […]
