Question

What do you do if the person is unable to breathe on their own or is having difficulty breathing ?

Answer 1

Person's airway, breathing, and pulse needs to be checked. If he getting worsen start CPR.

Loosen any tight clothing check for any respiratory obstruction  

Prerson may be using any prescribed medicine or inhaler.

Continue to monitor the person's breathing and pulse until medical help arrives. DO NOT assume that the person's condition is improving if you can no longer hear abnormal breath sounds, such as wheezing.

If there are open wounds in the neck or chest, they must be closed immediately, especially if air bubbles appear in the wound. Bandage such wounds at once.

A "sucking" chest wound allows air to enter the person's chest cavity with each breath. This can cause a collapsed lung. Bandage the wound with polythene or plastic wrap, or gauze pads covered with petroleum jelly. This allows trapped air to escape from the chest, but it prevents air from entering the chest through the wound.
