Severe Asthma

When to Go to the ER for Your Child's Asthma

Most asthma flares can be managed at home by following the action plan — a few extra rescue inhaler doses, some rest, maybe a call to the office the next day. But some symptoms cross a line where home management isn't enough, and recognizing that line quickly matters.

Call 911 or go to the ER immediately if your child has:

  • Severe difficulty breathing — visible chest retractions, nostrils flaring, or skin pulling in around the ribs with each breath.
  • Bluish lips, face, or fingernails — this signals oxygen levels are dropping and is always an emergency.
  • Trouble speaking, walking, or drinking due to breathlessness, or extreme drowsiness or confusion.
  • No improvement, or symptoms returning quickly, after rescue inhaler treatment given as directed by the action plan.
  • A peak flow reading in the "red zone", if your child's action plan includes peak flow monitoring.

When in doubt during a severe flare, err on the side of going in — it's always the right call.

When it's more of a "call us first" situation

Symptoms that are uncomfortable but stable — persistent cough, mild wheeze, a rescue inhaler that's helping but symptoms keep coming back within a few hours — generally warrant a call to our office rather than an immediate ER trip, since we can often adjust the plan same-day and avoid an unnecessary ER visit. The exception is always: if you're genuinely unsure, treat it as an emergency. Parents are right to trust that instinct far more often than they think.
