title: Drawbacks of pushovers.
abstract: Some military anaesthetists have started to use the Oxford Miniature Vaporiser in a pushover configuration with the Triservice anaesthetic apparatus. This vaporiser performs identically in the pushover and drawover configurations with the Cape TC 50 ventilator. We tested the Oxford Miniature Vaporiser with three other ventilators and found variable performance. When used in the pushover configuration with the Laerdal bag at normal minute volumes, the Oxford Miniature Vaporiser delivers a higher than set output.
