@yamikaa Hello, When someone has Asthma; their airways go into spasm which causes tightness of the chest. The linings of the airways become inflamed and produce phlegm leading to extreme difficulty in breathing. If someone is having an asthma attack, always follow the instructions outlined on their medication. However, if they do not have them to hand, these are the steps to follow.

Help him to sit straight and encourage them to take slow and steady breaths. If they do not start to feel better, they should take more puffs of their reliever inhaler If they do not start to feel better after taking their inhaler as above, or if you are worried at any time, contact the nearest hospital. They should keep taking the reliever inhaler whilst waiting for the paramedics to arrive
