I can say something about the brain..If oxygen is not transported to the brain by the blood,there are several effects that may occur according to how long oxygen is not transported to the brain..
In 1 minute,brain cells will begin to die but survival is possible .
in 3 minutes,brain damage likely...
when it reaches 10 minutes of lack of oxygen,the brain cells are dead..the patient is unlikely to recover.
In 13 minutes of oxygen shortage,recovery is virtually impossible..
