Remove the caps from the inhaler and spacer device. Shake the inhaler.
Put the inhaler into the open end of the spacer -- it’s opposite the spacer's mouthpiece.
Breathe out completely.
Put the mouthpiece of the spacer between your teeth and close your lips tightly around it.
Press the inhaler canister once to release the medicine, which will be trapped in the spacer.
Breathe in slowly and completely through your mouth. Some spacers will make a horn-like sound if you breathe too...
Feeling short of breath and having chest tightness. (Children may express chest tightness as a stomachache.)
In the yellow zone, your peak expiratory flow is 50% to 80% of your personal best peak flow measurement. To find 80% of your personal best, multiply your personal best measurement by 0.80. For example, if your personal best flow is 400, then 80% of that is 400 times 0.80, which is 320. And 50% of your personal best would be 400 times 0.50, which is 200. In this example, the yellow zone would be any value from 200 to 320. You may not have any symptoms, but your lung function is reduced.
Treatment for symptoms in the yellow zone includes the following:
Take your medicine according to your asthma action plan.
If symptoms do not improve within 20 to 60 minutes or if your peak expiratory flow remains less than 70% of your personal best measurement, or if both, then follow the red zone instructions of your asthma action plan, because your lungs are not responding to medicine.
If you keep going into the yellow zone from the green zone, talk with your doctor. Your regular medicine may need to be changed.
