All patients in an intensive care unit (ICU) have instability in at least one of the major body systems (cardiovascular, neurological and respiratory systems) or the potential for this to develop. If these systems are not functioning appropriately, death can result. The aim of intensive care is therefore to prevent this by monitoring for, recognising and treating any instability.
