Long-term effects can include vision problems, swallowing and speech difficulties, impaired thinking and judgment, personality changes, and memory loss. The longer someone is unconscious, the higher the chances of death or brain death and the lower the chances of meaningful recovery. Most people who have a meaningful recovery have been only unconscious briefly. Treatment involves restoring the flow of oxygen to the brain and depends on the cause of oxygen loss, but basic life support services must be used, such as mechanical ventilation blood produces to medications to support blood pressure and heart rate and medications to suppress seizures. Brain death (when there is no measurable activity in the brain).Seizures (uncontrolled unwanted movements, sensations, or behaviors).When the brain goes longer than five minutes with low oxygen it can cause: Having a hard time controlling movement.Cerebral hypoxia can kill brain cells and lead to brain damage and death. It is a medical emergency that can happen from many events where oxygen to the brain may be cut off, such as from drowning, choking, suffocation, cardiac arrest, or head injury. Cerebral hypoxia is a neurological condition that happens when the brain doesn't get enough oxygen, even though there is good blood flow.
