Central nervous system function in critical care

Using head trauma as an example, the authors discuss the treatment of acute brain damage. They, then, showed how the damage to the CNS soon causes problems to other organ systems, the most common example being the pulmonary system. Soon a complex dependent relationship develops, often pathologic, between the brain and lung. Both organs need medical care if the patient is to have a good chance of survival. Conversely, other organs like the lung, kidney, or liver can become affected and alter CNS function so that the same cycle is initiated. Again, both organ systems need aggressive treatment. Finally, we all recognize that once brain death has occurred other organ systems should not be inappropriatly maintained.
