Kids wit respir illness, airway inflamm, day 3&4 on orapred 2mg/kg, saw doc but no new plan. When do go back in when all short of breath wit min activ?

Call/Be seen. Don't know the age or size of your children or their history but if there is shortness of breath with minimal activity and on a very good dose of oral prendisone, if on adequate doses of albuterol mdi or updraft, i would call your doctor or doctor on call & discuss this with them. If you are concerned, go to the nearest urgent care center or er. Asthma is a serious disease & should be taken so.
Now. A child with shortness of breath with minimal activity should be seen right away, even in the emergency room if necessary.
