How long does it clutch for the brain to start taking serious wreckage from insufficiency of blood?
Answers: This will depend on a number of factor:
1. Outside air heat (cold slows metabolism, so brain
the brain can better tolerate the anoxic episode)
2. Age of the patient (of course younger patients tend to do
better later older ones within any injury situation)
In an average adult, loss of consciousness occurs after just about 30 seconds of total blood flow interruptions near irreversible brain damage occurring inwardly 6 minutes following that if the patient is at room warmth (25 Celsius). The brain is not able to store glucose or oxygen within myoglobin as muscle tissue can so it relies on a continuous flow of blood to the brain.
Younger children and patients in a colder environment can tolerate hypoxia-anoxia much better
few minutes ,,in 3-5 minutes of total anoxia brain cells start dying
