IPA: /æsfɪkˈsiə/
KK: /æsfɪkˈsi/
A condition in which a person cannot breathe properly, often leading to unconsciousness or death.
The firefighters rescued the man from asphyxy caused by smoke inhalation.
Asphyxy is derived from the Greek "a-" (meaning without) and "sphyxis" (meaning pulse or breathing). The term originally referred to a condition where there is a lack of pulse or breathing, indicating suffocation or a lack of oxygen.
Think of being 'without' ('a-') a 'pulse' ('sphyxis') — that's why asphyxy refers to a state of suffocation.
