The term "ICU" stands for "Intensive Care Unit." It refers to a specialized section in a hospital designed to provide comprehensive and continuous care for patients with severe or life-threatening conditions. The ICU is equipped with advanced medical equipment and staffed by specially trained healthcare professionals who monitor and support patients who require intensive medical attention.
The abbreviation "ICU" comes from the lengthy phrase "Intensive Care Unit." The term emerged as modern medicine advanced, particularly in the mid-20th century, when hospitals began recognizing the need for specialized care for critically ill patients.
