Principles of Urgent Management of Acute Airway Obstruction.

Recognizing and acting early on airway compromise reduces morbidity and mortality in patients with airway obstruction. Causes include foreign bodies, toxic/hot fumes, difficult intubation, laryngeal spasm, and tumors. Before definitive control of the airway is possible, provide 100% oxygen with a tightly fitting mask to optimize body oxygen stores. Pulse oximetry is a poor indicator of airway compromise; a decreasing arterial hemoglobin oxygen saturation is a late sign of impending hypoxemia. Basic airway maneuvers improve the patency of an obstructed airway. Getting help from an anesthetist early is a priority.
