intensive care

This term refers to a specific level of medical intervention characterized by a high ratio of staff to patients and the use of advanced life-support technology. It is almost exclusively used in clinical or hospital settings to describe a critical state of patient management.

In common usage, the term is frequently used as a modifier for the unit where this care is provided, such as in "intensive care unit" (ICU). Because it describes a specialized system of treatment rather than a discrete object, it is treated as an uncountable noun and does not have a plural form.
