A number of things, including allergies, a minor cold, and the flu can all cause airway discomfort. And complications from these usually minor conditions can be dangerous, especially in vulnerable people such as elders and children. Also, serious conditions such as aspiration, partial obstructions, pneumonia, and other disorders may also trigger airway discomfort. As a first responder, it’s important to know when airway discomfort is a sign of a serious problem, or just a passing symptom.
