Question

what will happen if the brain does not recieve oxygen for more than 4 minutes? what first aid should be given in this case?

Answer 1

Permanent damage begins after only 4 minutes without oxygen if a person is unconcious and is not breathing and death can occur as soon as 4-6 minutes later.

Cardiopulmonary resuscitation (CPR) is an emergency procedure that is performed on the person when his breathing or heart beat stops. It involves chest compression to create artificial circulation by manually pumping blood through the heart. In addition, it also provides rescue breathing to the person by either exhaling into the person's mouth or utilizing the device that pushes air into the person's lungs, a method of artificial respiration.
