What is the meaning of choking?

• A. Difficulty swallowing only
• B. The partial or complete obstruction of the flow of air into the lungs
• C. A sensation of dizziness
• D. Chest pain on exertion

Answer: (B)

Choking means the airway is blocked so air cannot reach the lungs. It’s about obstruction of breathing, not just difficulty with swallowing or feeling unwell. If the blockage is partial, some air can pass and the person may still cough or speak with effort. If it’s complete, no air gets through, speech stops, and the person may struggle to breathe, become distressed, and possibly turn blue as oxygen drops.

In a dental or clinical emergency, recognizing choking quickly is crucial because it signals an airway blockage that needs immediate attention. The other statements don’t describe airway obstruction: difficulty swallowing is a swallowing problem (not a blocked airway), dizziness is a separate sensation, and chest pain on exertion relates to the heart rather than an airway blockage.
