Final answer:
A person with a severe airway obstruction may exhibit signs of poor air exchange and difficulty breathing. Airway obstruction can be caused by various conditions, such as asthma or chronic obstructive pulmonary disease (COPD).
Step-by-step explanation:
A person with a severe airway obstruction may exhibit signs of poor air exchange and difficulty breathing. These signs can include:
- Labored breathing, producing gasping or wheezing
- Clutching at the throat or mouth
- Blue face from lack of oxygen
- Unconsciousness if oxygen deprivation continues
Airway obstruction can be caused by various conditions, such as asthma or chronic obstructive pulmonary disease (COPD). These conditions narrow the airways, making it more difficult for air to flow in and out of the lungs.
