title: The Afya anaesthesia system. A laboratory study.
abstract: The design of and the results of laboratory performance tests on the Afya anaesthesia system are described. The system has a low inspiratory and expiratory resistance and the concentrations of ether delivered ranged from 75 to 130% of the vaporizer setting. The error was maximum at vaporizer settings of between 15 to 20%. The system is suitable for spontaneous and controlled ventilation of the lungs in both adults and infants.
