“…mortality in terms of ICU mortality, hospital mortality, long term mortality; severity of illness with use of the Acute Physiology Score-APS; hospital costs for patients receiving intensive care and mechanical ventilation, quality of life after intensive care etc.) did not come to any solid recommendation (Chelluri, Grenvik and Silverman, 1995;Sprung and Eidelman, 1997).
