Coma,+vegetative+state,+unconsciousness+and+injury+Vs.+brain+dead+EAT


 * vegetation
 * pulse, blood pressure, body temperature, nutrition, and fluids are all artificial
 * everything they need is pushed into their body from a tube
 * these people are considered brain dead... and have no chance in recovering
 * brain dead
 * the brain cannot:
 * feel pain- it can feel the pain from other parts of the body... but not pain in the brain
 * the brain cant store oxygen
 * the brain cant store glucose
 * the brain can still be alive up to 6 minutes after the heart stops
 * it is important to learn CPR because if the heart is revived within 6 minutes the person can be saved
 * when the brain loses all neurological function- and it is irreversible
 * brain injury
 * the brain can either be bleeding, swollen, or both
 * injuries that can lead to brain death are:
 * trauma
 * gun shot wounds and such
 * anorexia
 * Cerebral vascular accident
 * stroke
 * ruptured aneurysm
 * infection
 * bacterial
 * fungus
 * viral
 * tumor
 * drug overdose
 * low glucose levels in the blood
 * bleeding
 * can be devastating
 * doctors can sometimes open the skull and control the bleeding
 * swelling
 * when the brain swells the ventricles collapse and the pressure in the skull increases
 * doctors often give the person an anti-inflammatory
 * as the internal pressure increases the swelling has no where to go... and if the pressure is the same as the blood pressure... then no blood will be able to enter the brain and it wil become brain dead
 * coma vs. brain dead
 * people who are brain dead... do NOT have a coma
 * people in a coma... could become brain dead
 * coma
 * people can survive a coma by vegetative state
 * there are different severities in a coma
 * a person in a deep coma has to stay in the hospital
 * a person who is in the vegetative state can be released from the hospital and stay with the family
 * has more low frequency brain waves
 * it has more lower brain function, and upper brain-stem function
 * in both cases the person is "legally alive"
 * people in a coma will have neurological signals

 * Coma case
 * what is a coma
 * when a person is unconscious
 * the person cannot respond
 * it is not a disease... it is a response/symptom to a disease of an injury/event
 * the average coma doesnt last more than 4 weeks (a month)
 * some people who have comas then slip into consistent vegetative state
 * a person can either fully recover or die from a coma depending on the severity
 * symptoms of a coma
 * unable to be brought to consciousness
 * no self-awareness
 * no sleep and wake cycle
 * unable to make voluntary movements
 * impaired breathing
 * causes of comas
 * most common is severe brain injury
 * diabetes
 * too much alcohol
