yes
The average adult can survive without oxygen for up to about five to ten minutes depending on the condition that they are in.
Cells anywhere in the body (especially in the brain) will die if deprived of oxygen enriched blood for long.
There is no reserve as such, oxygen is carried by haemoglobin molecules in the blood. It is transfered to parts of the body when it requires it. As such if a person stops breathing, the amount of brain damage sustained from a lack of oxygen increases with time, from approximately 4 minutes there is a risk. After 15 minutes it is very risky. This is why it is so important to start CPR as soon as possible.
The brain requires these chemicals to function, so if you don't get enough, you will experience first intoxication, then unconsciousness, and finally death.A personmay dieio heor she loss oxygen in his or her blood

No
The brain becomes deprived of oxygen when the creature depending on the brain fails to breathe. This can be reversed with quick medical attention; otherwise everything shuts down and the creature dies. Similarly if the air you are breathing is short of oxygen as in high altitude or with the use of gas mixtures such as nitrous oxide. with some of these situations it feel like you are breathing but you are in fact suffocating and causing damage to the brain.
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.
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.
The average adult can survive without oxygen for up to about five to ten minutes depending on the condition that they are in.
Every part of the human body needs oxygen, but the heart and the brain are the most critical body parts that will die soonest if they are deprived of oxygen. The brain dies in just 3 minutes without oxygen. Oxygen is carried by the blood, so if there is not enough blood, there will not be enough oxygen.
The medical standard for irreversible brain damage from not breathing is four minutes.
10 minutes
Cells anywhere in the body (especially in the brain) will die if deprived of oxygen enriched blood for long.
Brain damage start to occur at around 4-6 minutes in someone who's not breathing.
Basically the body, especially the brain needs oxygen to function well. If people don't breathe the brain will be deprived of oxygen causing suffocation and in the long run, death. And sometimes having problems with breathing is very dangerous specially when sleeping. Snoring is the best indication.
