What are signs of an obstructed airway?

The presence of an obstructed airway can be indicated by specific signs and symptoms that alert responders to the urgency of the situation. Inability to speak is a critical sign because it suggests that the airway is sufficiently blocked to prevent normal airflow and vocalization. Difficulty breathing further underscores the obstruction, as the individual struggles to get enough air. Coughing is another important sign, as it may indicate an attempt by the body to clear the obstruction; however, if a person is unable to cough effectively, it becomes a more serious concern. The occurrence of a high-pitched wheezing sound is a result of narrowed air passages and can also signal that an obstruction is present, indicating that immediate action may be necessary.

These signs are specifically related to airway obstruction, while other options provided in the choices focus on different physiological responses or symptoms that may not directly indicate an obstructed airway. For instance, excessive sweating and rapid heart rate can occur in various medical emergencies but do not specifically indicate an obstruction. Similarly, skin turning blue (cyanosis) and loss of consciousness suggests severe obstruction or other medical issues but represent later-stage consequences rather than initial signs. Feeling dizzy and faint is also a general symptom that can result from a range of conditions, which do not necessarily link
