ICU or Intensive Care Unit is a special part or ward of a hospital that has different types of machines and experienced doctors. The patients in critical health conditions are admitted to the ICU. Here, patients are continuously monitored by machines and the doctors keep a check on any change in their conditions and treat them accordingly.
All the doctors, nurses and other medical staff working in the Intensive Care Unit are given special training. The health of patients admitted to this ward is seriously affected and requires constant monitoring, so a nurse takes care of only one or two patients at a time.
