Intensive care units (ICUs) are specialized hospital areas designed to provide comprehensive monitoring and treatment 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 work together to deliver critical care. Patients in ICUs often require close observation and may be on life support systems, such as ventilators or intravenous medications. The goal of an ICU is to stabilize patients, manage complex medical issues, and support recovery, ensuring they receive the highest level of care during critical times.
