Which sign may indicate that a patient's airway is obstructed?

The presence of wheezing or an inability to speak are key indicators that a patient's airway may be obstructed. Wheezing is a high-pitched, whistling sound that occurs when airflow is restricted in the airways, often due to conditions such as asthma or an obstruction. If a patient is unable to speak, it suggests that they are struggling to get enough air into their lungs, which can result from a blockage or severe restriction in their airway. This condition requires immediate attention as it can quickly lead to respiratory distress or failure if not addressed.

In the context of airway obstruction, other signs such as sheer panic in the patient's eyes may indicate distress but are not specific to airway obstruction. Visible bleeding from the nose does not directly suggest that the airway is obstructed, although it may pose additional risks. Coughing uncontrollably can indicate an irritation or other respiratory issue, but it can also be a mechanism to clear the airway. However, if coupled with wheezing or an inability to speak, it may still relate to a separate condition rather than confirming airway obstruction.
