What is an asthma attack?

An asthma attack, is also known as an asthma episode or flare, it is characterized by shortness of breath, cough, and wheezing which requires either medication or some other form of intervention for the asthmatic to breathe normally again.

An asthma attack is an episode of shortness of breath that requires treatment or medical intervention to restore normal breathing. At the time of the attack, the muscles around the bronchial tubes in the lungs are contracting and closing off the air passage that allows the movement of oxygen into and out of the lungs. The initial onset of an asthma attack allows an adequate amount of oxygen into the lungs but prevents carbon dioxide from leaving the lungs. In a prolonged attack, carbon dioxide builds up in the lungs and eventually the amount of oxygen decreases.

An asthma episode or attack typically occurs when an allergen or irritant affects the lungs. A person may feel tightness in the chest, or experience slight wheezing, coughing, restlessness or difficulty in trying to sleep, or trouble breathing. The passages that let air into the lungs constrict or narrow which makes it hard to get air in and even harder to get air out of the lungs. Additionally, the cells that line the airways begin to secrete more mucus than normal, and this tends to clog the air passages. When the air passages become irritated, they swell which causes more difficulty breathing. All of these problems – the narrowed air passages, excess mucus, and the swelling – make it difficult for a person with asthma to breathe. Asthma attacks may be severe or mild. Some people with mild asthma may have symptoms but never have an actual asthma attack. People with asthma should be taught how to use their medications in order to prevent an attack and to help them if an attack occurs.

An asthma attack is an episode when the airways become narrower, muscles around the airways tighten, and mucus production may increase, making it difficult for your child to breathe. Asthma attacks are usually caused by exposure to an asthma trigger.

An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around your airways (bronchospasm). During the asthma attack, the lining of the airways also becomes swollen or inflamed and thicker mucus — more than normal — is produced. All of these factors — bronchospasm, inflammation, and mucus production — cause symptoms of an asthma attack such as difficulty breathing, wheezing, coughing, shortness of breath, and difficulty performing normal daily activities.
