Etymology
The word 'asphyxiation' has a precise medical origin rooted in ancient Greek physiology. It derives from the Greek asphyxia, a compound of a- (meaning "without") and sphyxis (meaning "pulse" or "heartbeat"). Literally, it described the condition of being "pulseless." This term entered scientific Latin and later English, where its meaning broadened from the specific stoppage of the pulse to the more general process of suffocation or oxygen deprivation that causes it. The modern abstract meaning thus logically evolved from the observable physical symptom (absence of pulse) to encompass the entire causal process of being deprived of vital air.
