Perspectives in ICU computing.

Computers have unrealized potential in investigation and clinical care. Computers in Critical Care and Pulmonary Medicine must serve as a catalyst to focus these efforts. The goal must be development of practical, cost effective systems to facilitate the collection, recording and interpretation of data relevant to the management of the ICU patient. The ultimate goal is to provide feedback control where appropriate. To reach this goal, data relevant to the elements of the gas exchange system - the heart, the lungs, and ventilatory pump - are essential and analysis systems are needed. Analysis must interpret the interaction between circulatory and lung function and between lung, chest wall and diaphragm mechanics and gas exchange.
