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. It is 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 continuous support. Patients in the ICU often require constant observation and may be on life-support systems, such as ventilators or intravenous medications. The unit is designed to handle critical situations, ensuring that patients receive the necessary interventions to stabilize their health and improve their chances of recovery.
