Intensive care is a specialized branch of medicine dealing with the diagnosis, management, and follow up of critically ill or critically injured patients. It requires input from other branches of medicine on various issues. A critical care specialist has expertise in managing such patients round the clock. Based on his freedom to take decisions in the intensive care unit (ICU), different types of ICUs - open, closed, or semi-closed - have been defined. There is no doubt that all critical patients should be evaluated by an intensivist. Therefore, it is argued that a closed ICU model would be the ideal model. However, this may not always be feasible and other models may be more useful in resource-limited countries. In this review, we compare the different formats of ICU functioning and their suitability in different hospitals.
