title: Alveolar gas relationships during the use of semi-closed rebreathing anaesthetic systems.
abstract: A black box and a geometrical approach have been used to deduce the relationships between alveolar oxygen and carbon dioxide concentrations when rebreathing occurs during the use of semi-closed anaesthetic rebreathing systems.
