Anapneo is a spell that is used to clear a blocked airway.
Extended description edit
Professor Slughorn cast this spell on Marcus Belby when the latter began to choke after swallowing too fast.
The incantation for this spell is based on the Greek πνοη (breath), which is also seen in a number of words in English starting with "pneu-"; the prefixed α may mean "no" with the αν in front of that negating the negative, to change this to mean "restore stopped breath".
