For the patient with breathing problem, first aid can be performed
Firstly Check the person's airway, breathing, and pulse. If necessary, begin CPR.
Loosen any tight clothing.
Help the person use any prescribed medicine (such as an asthma inhaler or home oxygen).
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 plastic wrap, a plastic bag, or gauze pads covered with petroleum jelly, sealing it on three sides, leaving one side unsealed. This creates a valve to prevent air from entering the chest through the wound, while allowing trapped air to escape from the chest through the unsealed side.
