After what time the does the ischemic brain of an accident casualty die?
Show the correct answer
Correct answer
A. After approx. 4-5 minutes.
Explanation
The question is about how long it takes for the brain of a person whose circulation has stopped to die. This happens after only about 4-5 minutes - the answer is A.
The Road Traffic Act requires a driver involved in an accident in which someone is injured to give the necessary help to the victims and to call the emergency medical team, and the Criminal Code punishes anyone who does not give such help even though they could have done so without putting themselves at risk. These few minutes show exactly why you must not wait: when the heart stops pumping blood, the brain does not get oxygen, and after about 4-5 minutes permanent damage starts in it. An ambulance rarely arrives within such a time, so 20 minutes (answer B) or an hour (answer C) are times at which, without help from witnesses, the chance of survival practically disappears. That is why you call 112 straight away and start chest compressions.
