An intensive care unit (ICU) is an inpatient ward where patients with critical health problems who need to be closely monitored receive follow-up, examination and treatment services. Patients treated in intensive care are monitored 24 hours a day. In order to provide this service, nurses working in intensive care are usually responsible for the follow-up of one or two patients.
Intensive care units are equipped to intervene early and effectively in patients whose general condition suddenly deteriorates or whose health deteriorates rapidly. In intensive care units, specialized medical devices such as respiratory support devices, also known as mechanical ventilators, oxygen support systems, dialysis and bedside imaging equipment are used.
Intensive care units are managed by taking serious precautions in order to maintain health services in the most efficient way and minimize the risk of infection, taking into account the critical condition of the patients. For this reason, relatives of patients can meet with patients hospitalized in intensive care at certain times of the day or receive information from the responsible healthcare professional. Care is taken to ensure that the relatives of the patients who come to visit are 1st degree relatives.
Intensive care units in hospitals are sub-classified according to specialization and the health status of the patients cared for. Accordingly, hospitals may have the following intensive care units:
- Medical (medical, internal medicine) intensive care unit,
- Surgical intensive care unit,
- Pediatric intensive care unit,
- Coronary intensive care unit,
- Anesthesia intensive care unit or post-anesthesia intensive care unit (PACU),
- Neonatal intensive care unit,
- Trauma intensive care unit.
