Abstract
A fault in the assembly of a Matrix Large Animal Circle anaesthetic ma chine resulted in reversal of fresh gas flow through the vaporizer. Th e fault was discovered only after the sudden development of excessive depth of anaesthesia in two equine patients. Laboratory investigations were conducted to determine the effect of flow reversal on vaporizer output. Results indicated that output concentration was approximately doubled under these conditions.
