We report the in vitro longevity of a conventional soda lime carbon dioxide absorbent and an absorbent free from strong alkali (Amsorb™). Although the times taken to breakthrough of carbon dioxide (> 0.5%) within an in vitro low flow breathing systern were shorter with the alkali‐free absorbent, we found that the size and shape of the absorbent container was the major factor in determining the efficiency of the carbon dioxide absorbents.
