22 minutes are 22 minutes.

Brain death is the irreversible end of all brain activity. The term brain death should not be confused with a persistent vegetative state like many people tend to do.
Permanent brain damage can occur within 4-6 minutes without oxygen. After this time, irreversible damage to the brain cells begins to occur due to oxygen deprivation. Immediate medical intervention is critical to prevent long-term consequences.
I take my heart outside with me, every time I go out. If you meant outside the chest cavity, I would estimate perhaps 3 minutes before brain death.
Your brain needs 5 minutes of sleep. Your body needs 8 hours of sleep.
Brain death can't be determined if the heart has already stopped, this would be considered cardiac death. Brain death is determined when someone is on a ventilator (not breathing on their own due to injury or illness) and an EEG or other procedure has been completed and shows no signs of brain activity. The body will continue to "live" with the help of the ventilator oxygenating the organs, but when taken off the ventilator then the body has no impulse to breathe for itself due to the brain being dead.
The removal of the brain results in the fastest death. Although there are many ways of facilitating death (shooting, poisoning, infection, gassing etc), all deaths are the result of full loss of brain function. Loss of brain function can occur from: - direct damage to the brain: infection, disease or trauma such as shooting or crushing; or - loss of oxygen to the brain: blood loss via injury or shock, blockage to vessels, failure to pump oxygen (heart failure or poisoning).

There are many types of brain injuries that can occur. Traumatic brain injury is the most common one that occurs from something physical usually. They tend to occur from vehicular, construction or even sports accidents.
About 6 minutes before brain cells start to die. If a person has a cardiac arrest resuscitation has to begin within this time to be successful. The time may be prolonged if the body is cooled, for example by drowning in ice cold water.As mentioned, temperature (specifically metabolism) plays a very big role in how long you can go without oxygen, but as general guideline:Heart: Needs constant oxygenBrain: 4-6 minKidneys: +- 30 minMuscles: +- 2-4 hoursGI Tract: +- 12 hoursThus, the main areas of concern is the heart and the brain.A human body ca only live for six minutes without oxygen, before the brain cells start to die.
On average, humans can survive around 3 to 5 minutes without oxygen before experiencing severe brain damage or death. The exact time can vary based on individual health, fitness, and other factors.
