Upper airway obstruction may occur during recovery from anesthesia. Principal signs are the lack of adequate air movement, intercostal and suprasternal retractions, and paradoxical abdominal and chest wall motion during inspiration. It can occur immediately after extubation in the operating room or can be delayed and occur in the PACU, on the general care floor, or in the ICU.
