It is roughly around 3 minutes and it depends on the person (i.e. baby, adult...etc.). Brain damage is irreversible no matter how long you are without oxygen. Once brain damage begins you can never regain those cells that have died.
2-4 minutes
Breathing stops for a moment when swallowing. So no breathing occurs when swallowing.
There are a lot of variables, but 4 minutes is the usual guideline. Blood carries oxygen, and blood is pumped by the heart. Brain damage occurs after 4 minutes without fresh oxygen to the brain.
it stops the blood flow to your brain either killing you or giving you serious brain damage
Developmental regression occurs when a child's mental or physical development stops and begins a reverse cycle. Examples are from brain damage, or a disease which would retard the growth cycle.
Till the age of 18, the brain grows. After that the brain stops growth. That is why when there is a brain damage, it is always permanent.
Your Brain will function for at least 6 to 7 minutes after your heart has stopped.
When breathing stops from lack of oxygen
Yes, if a patient has stopped breathing and does not have a heartbeat, they are considered legally dead. This is typically confirmed through an evaluation by a medical professional or through standard diagnostic tests.
if the human brain stopped working the whole system of the body will stop working because the brain is the power house of the whole systems and it generates different types of impulses ( motor & sensory) to control voluntary and involuntary movements of the human body.
