An in-circuit vaporizer for delivery of isoflurane was evaluated. The isoflurane concentration within an isolated circle breathing circuit was determined for 1 hour in 6 in-the-circuit vaporizers with the wicks removed. A mechanical ventilator and artificial lung were connected to the circuit. ⋯ Cardiovascular function, respiratory function, and recovery times were within clinically acceptable ranges. The initial vaporizer tap setting (mean +/- SEM) was 8.2 +/- 0.4, and this corresponded to an end-tidal isoflurane concentration of 3.5 +/- 0.6. The range of vaporizer settings during the maintenance phase (mean +/- SEM) was 2.8 +/- 0.5 to 4.6 +/- 1.9.(ABSTRACT TRUNCATED AT 250 WORDS)
