AN EVALUATION OF THE UNIVERSAL PAC AND OXFORD MINIATURE VAPORIZERS FOR PEDIATRIC FIELD ANESTHESIA

A laboratory study has demonstrated that the Universal PAC ann Oxford Miniature Vaporizers can be used for paediatric anaesthesia in drawove r mode at varying ambient temperatures. Changes in tidal volume have m inimal effect on the delivered concentration of halothane from either vaporizer but varying ambient temperature significantly affects the ou tput of the Oxford Miniature Vaporizer. The Oxford performs well in co ntinuous flow mode, which is of particular use for T-piece anaesthesia , whereas rite Universal PAC does not perform adequately in this way.
