If you suffered a blow to your head or body, then you should immediately contact emergency services. You want to be transported to the hospital in a safe manner. Additional brain damage could make recovery much harder, so you need to be careful.
Victims who suffer severe brain injuries are usually admitted into the Intensive Care Unit (ICU), where doctors will monitor their vital signs and make sure the brain receives enough oxygen. Once the patient is stabilized, he or she can be discharged from the ICU, though they will need to stay in the hospital for additional time.
