The invention relates to an arrangement (200) for anaesthetising a living creature (V) and for maintaining said creature in an anaesthetised state, by administering thereto an infused volume of anaesthesia inducing pharmaceutical (22) in liquid phase per unit of time, with the aid of one or more lung ventilator units (A) and one or more infusion units (B). Chosen parts of the lung ventilator unit, with the exception of external insufflation hose, expiration valve, measuring probe and a number of hoses (12), and selected parts of the infusion unit (B), with the exception of cannula (5B) and hose ( 4B) are mutually combined to form a single equipment unit (201) . Some of the parts of the equipment unit are mutually coordinated with respect to communication via a computer unit (600) included in the equipment unit, and the computer unit is adapted to monitor unit related criteria and creature related criteria.

An arrangement according to claim 1, further comprising an equipment unit including at least said at least one ventilator unit, at least one therapeutic unit and at least one diagnostic unit, wherein at least one of said at least one therapeutic unit and said at least one diagnostic unit is structured on at least one printed circuit board, which has a function unit mounted thereon; wherein said at least one board is co-ordinated in an equipment unit, with one input of respective units connected to one part of a two-part coupling device, and wherein said part of said coupling device is attached to and co-ordinated on said equipment unit. 3. An arrangement according to claim 2, wherein said equipment unit has connected thereto and/or affixed thereto said display unit, which is adapted for the display of at least one of instantaneous criteria value and timewise variation of the criterion on said display surface. 4. An arrangement according to claim 1, wherein first criteria related to a diagnostic unit, and second criteria related to a therapeutic unit can be presented on a display surface of the display unit; wherein said first criteria are chosen for display on said display surface as instantaneous values; and wherein said first criteria are chosen for display on said display surface as timewise variation of the criterion. 5. An arrangement according to claim 1, wherein time axes of selected criteria of at least one of said unit-related criteria and said creature-related criteria chosen to be shown as timewise variation of respective criteria are co-ordinated and arranged in mutually superimposed relationship. 6. An arrangement according to claim 1, wherein signals generated by a measuring probe, a sensor in respect of chosen criteria of said unit-related criteria or said creature-related criteria are time-delayed prior to said chosen criteria being presented on the display surface. 7. An arrangement according to claim 1, wherein instantaneous values and values concerning time related graphs for criteria related to a diagnostic unit and instantaneous value concerning time-related graphs for criteria related to a therapeutic unit can be stored in memories for presentation as timewise variation of the respective criteria. 8. An arrangement according to claim 7, wherein the timewise variation of said respective criteria can be presented in a time compressed form. 9. An arrangement according to claim 2, further comprising an equipment unit including at least said at least one lung ventilator unit and a plurality of said hoses, and wherein a first coupling part of a two-part hose coupling of at least one of said hoses is attached to said equipment unit, and said coupling part is adapted for a co-action with an external hose section for an insufflation gas flow and a plurality of external hose sections. 10.
