Without oxygen it takes as little 4 minutes for brain damage to occur once oxygen has been cut off.

If you don't get oxygen within 5 minutes to 6 minutes permanent brain damage can set it and even death can occur.

So it's important to begin CPR on a person who is not breathing right away and get medical attention as fast as you can too.

After five to ten minutes of not breathing, you are likely to develop serious and possibly irreversible brain damage.

The one exception is when a younger person stops breathing and also becomes very cold at the same time.

The 4 types of traumatic brain injuries include.

Coup-Contrecoup Brain Injury.
Brain Contusion.
Second Impact Syndrome.
Penetrating Injury.

Another traumatic brain injury is Shaken Baby Syndrome.

Other types of traumatic brain injuries are.

Concussion. Concussions are one of the more common traumatic brain injuries.
Edema. Edema refers to the swelling of the brain that can occur as a result of any traumatic brain injury.
Diffuse Axonal Injury.
Hematoma.
Skull Fracture.
Hemorrhage.
Hypoxic/anoxic Brain Injury.
Stroke.

It is OK to give or take Tylenol after a head injury.

Tylenol, Ibuprofen and other pain relievers are safe to take for pain after a head Injury.

When you have a head injury you can safely take ibuprofen or other pain relievers.

After the first 24 hours, ibuprofen (Advil) and naproxen sodium (Naprosyn, Aleve) are generally more effective for pain relief, and are safe.

In some patients, nausea and vomiting can be bothersome, and prescription medications can help.

Restful sleep is important in all stages of recovery from concussion.

Some ways to treat a head injury at home are.

Rest quietly for the day.
Use ice packs over any swollen or painful area.
Take simple painkillers such as paracetamol for any headache.
Arrange for someone to stay with you for the next 24 hours, in case you need help.

However be aware that if you do suffer a head injury or a blow to the head even if it seems minor you should always go to the emergency room for treatment and to get checked out.

Some people have suffered blows to the head or head injuries that they thought were minor and then they died as a result.

Having just one concussion is too many although if you have more than one concussion then you could suffer other health problems and brain problems as well.

The risks of sustaining multiple concussions are serious.

Research has shown that people who have multiple concussions are at an increased risk of long-term impairment, such as forgetfulness, “foggy” thinking, difficulty concentrating, balance issues, difficulty focusing and trouble with eyesight.

A concussion is a traumatic brain injury that affects your brain function.

Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination.

Concussions are usually caused by a blow to the head.

Approximately 80 percent of concussions resolve over seven to 14 days, with an average of 10 days.

People with concussions should never return to sports or other physical activity sooner than one week from sustaining the injury.

Sleeping isn't dangerous when you have a concussion.

You won't slip into a coma or die if you go to sleep after getting a concussion.

It's safe for a concussed person to sleep if they are awake and can hold a conversation, and they don't have obvious concussion symptoms.

In general, any head injury associated with loss of consciousness, seizures, prolonged confusion or amnesia, neck pain, vomiting or numbness or weakness in arms or legs should be transported to the emergency room in an ambulance right away.

Seek emergency care for an adult or child who experiences a head injury and signs and symptoms such as: Repeated vomiting or nausea.

A loss of consciousness lasting longer than 30 seconds.

A headache that gets worse over time.

Your doctor will recommend that you physically and mentally rest to recover from a concussion.

Relative rest, which includes limiting activities that require thinking and mental concentration, is recommended for the first two days after a concussion.

The symptoms of a concussion include.

Headache or “pressure” in head.
Nausea or vomiting.
Balance problems or dizziness, or double or blurry vision.
Bothered by light or noise.
Feeling sluggish, hazy, foggy, or groggy.
Confusion, or concentration or memory problems.
Just not “feeling right,” or “feeling down”.
