Choking
mechanical obstruction of the flow of air from the environment into the lungs
Choking, also known as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract. An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation. Although oxygen stored in the blood and lungs can keep a person alive for several minutes after breathing stops, choking often leads to death.
Around 4,500 to 5,000 choking-related deaths occur in the United States every year. Deaths from choking most often occur in the very young (children under three years old) and in the elderly (adults over 75 years). Foods that can adapt their shape to that of the pharynx (such as bananas, marshmallows, or gelatinous candies) are more dangerous. Various forms of specific first aid are used to address and resolve choking.
Choking is the fourth leading cause of unintentional injury death in the United States. Many episodes go unreported because they are brief and resolve without needing medical attention. Of the reported events, 80% occur in people under 15 years of age, and 20% occur in people older than 15 years of age.
This brief starts where responsible research should: with the source description of “Choking” as mechanical obstruction of the flow of air from the environment into the lungs. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as mechanical obstruction of the flow of air from the environment into the lungs. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q19275831. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
