Giving First Aid Treatment to a person who has suffered an Asthma Attack
An asthma attack occurs when the airway passage constricts (closes) to prevent the entry for dust or it may be due to an allergic reaction.
This causes the muscles in the lungs to go into spasm such that breathing becomes difficult.
Usually, the Asthma Pump acts as a bronchodilator as it relaxes the lung muscles to allow person to breath normally.
