Asthma is a chronic (long-lasting)
inflammatory disease of the airways that
causes varying degrees of obstructions in the
air ways.
It is a condition in which the airways narrow
and swell and produce extra mucus. This can
make breathing difficult and trigger
coughing, wheezing and shortness of breath.

Check vitals.
Monitor pulse oximetry and peak flow.
Demonstrate the proper use of metered dose
inhaler properly.
Reassure the patient during an asthma attack
Place the patient in semi-fowler position and
encourage breathing and provide nebulisation.
Assist him to relax as much as possible to reduce
anxiety.
Administer bronchodilators and corticosteroids
