What is an ICU? The intensive care unit of a hospital is usually where patients that are seriously ill, or those that require specialized care, are admitted. … The ICU also has special guidelines for visitors. Visitors may be requested to stay in the room of the patient they are visiting

Generally, physical recovery occurred within six months of being discharged from the hospital. Emotional recovery can take longer. In a recent analysis of 38 studies, researchers found that about one-third of ICU patients, both young and old, develop depressive symptoms that persist through 12 months of follow-up.
When someone is brain dead, it means that the brain is no longer working in any capacity and never will again. Other organs, such as the heart, kidneys or liver, canstill work for a short time if the breathing machine is left in place, but when braindeath is declared, it means the person has died.
