During An
Asthma Attack
What happens during an asthma attack?Children with asthma have acute episodes when the air
passages in their lungs become narrower, and breathing becomes more
difficult. These problems are caused by an over-sensitivity of the lungs
and airways.
- The lungs and airways overreact to certain triggers causing:
- the lining of the airways to become inflamed and swollen.
- tightening of the muscles that surround the airways.
- an increased production of mucus.
- Breathing becomes harder and may hurt.
- There may be a wheezing or whistling sound, which is typical
of asthma. Wheezing occurs because of the rush of air which
moves through the narrowed airways.
If a child does not receive treatment immediately during an asthma
attack, respiratory failure may occur.
