[Anesthesia programmed by enflurane]

A microcomputer type 6502 is the central unity of a volatile anaesthetic injector for use in a closed circuit breathing system. Estimated calculations for quantity of anaesthetic liquid are done in agreement with the formula of J.W. Severinghaus and H. Lowe. Clinical assay is realised with enflurane. The syringe efficacy is controlled by permanent recorder of halogenate concentration in upper airways Fi-FA: infrared analysor cosma Rubis 3000).
