Determining the probability of a foreign body aspiration from history, symptoms and clinical findings in children

<span class="paragraphSection">Editor—Life-threatening events with an acute airway obstruction require immediate intervention. Nevertheless, most cases of foreign body aspiration (FBA) result in expectoration or dislodgment into a main-stem bronchus, with subsequent normalization of breathing and non-specific respiratory symptoms occurring days or even weeks after the FBA, often not recognized by health care providers<a href="#aex023-B1" class="reflinks">¹</a> or parents.<a href="#aex023-B2" class="reflinks">²</a> Bronchoscopy is a potentially harmful procedure requiring specialist expertise in small children.<a href="#aex023-B3" class="reflinks">³</a> Therefore, simple and reliable identifiers for the probability of actual FBA would be highly desirable.</span>
