First Aid Advice for Stridor (also use for any difficulty breathing or severe coughing)

• Inhale warm mist in a foggy bathroom with the shower running, from a wet washcloth held near the face, or from a humidifier (add warm water) for 20 minutes. (Caution: avoid very hot water or steam which could cause burns or high body temperatures)
• If that fails, inhale cool air from breathing near an open refrigerator or taking outside for a few minutes.
• Warm mist may also be helpful for difficulty breathing or severe coughing without stridor
