An Intensive Care Unit (ICU) is a specialized section of a hospital designed to provide comprehensive care for patients with severe or life-threatening conditions. These units are equipped with advanced medical technology and staffed by a team of healthcare professionals, including doctors, nurses, and respiratory therapists, who monitor patients closely and provide necessary treatments. Patients in the ICU often require constant observation and support for vital functions such as breathing, circulation, and organ function. Common reasons for admission include major surgeries, severe infections, or traumatic injuries. The goal of the ICU is to stabilize patients and facilitate their recovery.
