Upper airway obstruction happens when there is an anatomic narrowing or occlusion that results in a reduced ability to exchange gas in and out of the lungs. The obstruction can lead to respiratory failure, arrhythmias, cardiac arrest or death within minutes. Therefore, healthcare professionals must be aware of signs and symptoms, possible causes and management in order to intervene promptly and minimise morbidity and mortality.
In this article we review the tool LEMON which has been used in different clinical settings.
