Breathing doesn't immediately stop if the brain is deprived of oxygen. The brain can tolerate a brief period without oxygen before irreversible damage occurs. However, prolonged oxygen deprivation can lead to loss of consciousness and eventually breathing may stop.
In newborns, breathing can stop within 2-3 minutes if the brain is deprived of oxygen. Oxygen deprivation can lead to serious health complications, including brain damage and even death if not promptly addressed. It is crucial to monitor newborns closely and seek medical attention immediately if there are any concerns about their breathing or oxygen levels.
The brain can be deprived of oxygen due to events like drowning, choking, stroke, heart attack, or suffocation. When oxygen supply to the brain is restricted, brain cells can quickly begin to die, leading to serious consequences like permanent brain damage or even death.
If the 4-5 minutes of no breathing means 4-5 minutes of no oxygen in the brain then it will lead to necrosis or tissue death. The brain will start to degenerate and die.
Brain death due to lack of oxygen can occur within minutes, typically 4-6 minutes, after the brain is deprived of oxygen. The exact time frame can vary depending on factors such as the individual's health, age, and the cause of oxygen deprivation. Immediate medical intervention is crucial to prevent irreversible brain damage.
Brain damage can occur within minutes of not receiving oxygen, with irreversible damage starting to occur after about 4-6 minutes. The longer the brain is deprived of oxygen, the more severe and long-lasting the damage is likely to be. Treatment must be administered quickly to minimize the extent of brain damage.
The organism will die. The heart pumps blood, which carries oxygen to all parts of the body- including the brain. If the brain is deprived of oxygen for more than 4 minutes, under most circumstances, the brain dies. When the brain dies, the organism dies.
If the brain is deprived of oxygen for 5 minutes (flat line), it can lead to irreversible brain damage. Prolonged lack of oxygen can cause brain cells to die, potentially resulting in long-term cognitive impairments or even brain death. Immediate medical intervention and resuscitation efforts are crucial to prevent permanent damage.
The medical standard for irreversible brain damage from not breathing is four minutes.
10 minutes
When an animal is deprived of oxygen, their body will be unable to produce energy through aerobic respiration, leading to cell damage and potentially death if oxygen deprivation lasts for too long. Without oxygen, the brain is particularly vulnerable, and lack of oxygen can result in irreversible brain damage within minutes. The body will try to compensate by increasing heart rate and trying to take in more oxygen, but prolonged deprivation will eventually lead to organ failure.
Brain damage start to occur at around 4-6 minutes in someone who's not breathing.
