Example Input: Oxygen is crucial to sustaining life. Though it varies from person to person, on an average, 3 minutes is the maximum time where the person can stay alive without oxygen. Yoga and meditation experts may hold breath for longer than this, but these are very rare examples. In an absence of oxygen, brain cells begin to die and this effect is irreversible! The brain cannot go without oxygen for more than ten minutes. If oxygen is not able to get to the brain before this, then there is a possibility of irreversible brain damage. The brain cannot go without oxygen for more than ten minutes. If oxygen is not able to get to the brain before this, then there is a possibility of irreversible brain damage. How long can someone go without oxygen before there is brain damage ? If someone has been without oxygen for 15 minutes is there any hope that they can wake from a coma without any brain damage. If there is brain damage, is it always severe or does it depend on each patient ? Questions and Answers About Transplantation and Donation. Below are some frequently asked questions about brain death, how organ donation works, the need for donors, organ failure, and transplantation. 1. What do medical personnel do to save the life of a person with a head injury? 2. What kinds of injuries may lead to brain death? 3. How long can the brain go without oxygen before serious damage occurs? 4. What happens when your brain is injured? 5. What can be done if your brain is injured? 6. What is brain death? Doesn't the person's heart have to stop for them to be dead? 7. How can you tell if someone is brain dead? 8. What does a brain dead person look like? 9. If the person is brain dead how can the heart still be beating? 10. 3. How long can the brain go without oxygen before serious damage occurs? 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. This can occur when a child is suddenly plunged into very cold water and drowns. In this situation, survival after more than 30 minutes has been known to occur. Return to the list of Frequently Asked Questions >> So expect a minute at most before permanent brain damage, and maybe 3 minutes at max before total death. And if you want to experience having overly oxygen-rich blood, take a few deep, meditative breaths. Humans are aerobic creatures, meaning we require oxygen to release energy and exist. Without oxygen, our cells wouldn’t be able to release the energy in the food we eat, and we would die. We take in oxygen through respiration — we move air in and out of the lungs, and blood takes oxygen to the cells of the body. Carbon dioxide, a waste product in our bodies, is moved out of the body by the same system. Breathing has always been synonymous with life. Our speech is permeated with idioms and phrases relying on the idea that taking a breath is the surest sign of vitality, and we constantly compare things we need to our body’s ultimate necessity: oxygen. Under relatively normal circumstances, we start struggling after a few minutes without oxygen. Without being able to convert energy and use it up, cells start to die. This happens throughout the entire body, but it is the brain’s lack of oxygen that is most urgent. “The brain is a highly metabolically active organ,” Tishler said. “It needs oxygen to generate the energy to function. Without the energy (without oxygen) it dies.” The brain normally takes up about 20 percent of the body’s oxygen. If it doesn’t get what it needs, cells begin dying off, putting a person at risk of permanent brain damage. If a person suffocates, or suffers another type of involuntary oxygen deprivation, they’ll ultimately suffer brain death: the utter, irreversible loss of brain function. It’s a pretty unavoidable succession of events. Between 30-180 seconds of oxygen deprivation, you may lose consciousness. At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable. At 15 minutes, survival becomes nearly impossible. There are, of course, exceptions to every rule. Some training routines help the body make more efficient use of oxygen, enabling the brain to go longer periods without this vital element. Free divers routinely train to go long periods without oxygen, and the current record holder held his breath for 22 minutes without sustaining brain damage! Query: how long can a human go without oxygen prior to brain damage
Example Output: On an average, 3 minutes is the maximum time where the person can stay alive without oxygen.
