If after a traffic accident an injured person does not respond and apparently has lost consciousness, what is the first thing we should do?
A)Look for external or internal haemorrhages to prevent them from bleeding out.
B)Open the airway and remove foreign bodies from the mouth, using manoeuvres that do not manipulate the spine.Correct
C)Lay them in the so-called recovery position so they breathe more easily.
When a person is unconscious after a traffic accident, the priority is to ensure that they can breathe properly. Opening the airway and removing any obstruction is essential to ensure adequate oxygenation of the body. However, it is important to do so carefully so as not to manipulate the spine, as there could be serious injuries in that area due to the accident.
It is crucial to follow the appropriate protocol for handling emergency situations like this, as acting incorrectly could worsen the injured person's condition.
