title: The magnitude of air admixture with a jet device in paediatric anaesthesia.
abstract: The admixture of air in inspired gas with a paediatric insufflation system based on a gas jet has been investigated. During anaesthesia with spontaneous ventilation 1% of air per kg body weight was found in tracheal gas samples. A venturi effect was virtually absent even at high jet flows, which suggests that artificial ventilation prevents air admixture.
