The complication that arises most commonly for unconscious patients concerning their airway is the potential for airway obstruction due to the tongue. When a patient is unconscious, they lose the muscle tone of the tongue and surrounding soft tissues. This loss of control allows the tongue to fall backward and obstruct the airway, making it difficult or impossible for air to enter the trachea. This can lead to hypoxia and is a critical situation that requires immediate intervention.

In contrast, while other factors like nasal congestion or excessive mucus production can indeed impact airway management, they are generally less critical when considering unconscious patients specifically. Pneumothorax, while a serious condition, is not directly related to the immediate risk of airway obstruction in this context. Understanding the risks associated with airway management in unconscious patients is crucial for timely and effective medical response.
