Abstract
An anaesthetic machine has a gas flow system with a variable-volume gas container for breathing gas, a fresh gas system for supplying the fresh gas system with a flow of fresh gas and a control unit. The control unit controls the variable-volume gas container during a first phase of inspiration so that a flow of breathing gas is released and mixes with a flow of fresh gas from the fresh gas system. The control unit starts a second phase of inspiration if the flow of breathing gas from the variable-volume gas container ceases before inspiration has been completed. The control unit controls the anaesthetic machine during said second phase so that inspiration is maintained with a flow of fresh gas from the fresh gas system in order to achieve a system in which all breathing modes can be accommodated and gas consumption is minimized.
