Abstract
A number of different parameters related to carbon dioxide output of a patient are routinely determined in ventilator/anaesthetic systems. For this purpose, a ventilator/anaesthetic system for determining carbon dioxide parameters includes a ventilator unit in which a first flow meter is arranged to measure an expired flow of gas, and a carbon dioxide meter is arranged to measure the concentration of carbon dioxide in expired gas. Arranging the carbon dioxide meter in the ventilator/anaesthetic unit minimizes the equipment which must be located in the immediate vicinity of patient, and a faster, more sensitive carbon dioxide meter thus can be used.
