Sometimes, no matter how careful you are about taking your asthma medicines and avoiding your triggers, you may find that you have an asthma attack or someone you know has one. In an asthma attack the muscles of the air passages in the lungs go into spasm and the linings of the airways swell. As a result, the airways become narrowed and breathing becomes difficult. People with asthma usually deal well with their own attacks by using a blue reliever inhaler, however you may be required to assist someone having an asthma attack or having an attack for the first time. If so, this is what you need to know.
