Abstract:
A method for monitoring a composition of a breathing gas mixture comprising a first gaseous component and a second gaseous component, comprising the steps of:providing a data processor with an indication of a moisture content value for said first gaseous component before mixing thereof with said second gaseous component; providing said data processor with an indication of a moisture content value for said second gaseous component before mixing thereof with said first gaseous component; after mixing said first gaseous component and said second gaseous component to obtain a mixture, measuring a moisture content value for said mixture and providing said moisture content value for said mixture to said data processor; and determining, in said data processor, a value indicative of an amount of one or both of said first gaseous component and said second gaseous component in said mixture, from said moisture content value for said first gaseous component, said moisture content value for said second gaseous component, and said moisture content value for said mixture.
