Etymology: "Ventilatory" is simply "ventilate" plus the suffix "-ory", which turns a verb into an adjective meaning relating to or serving a process. The verb "ventilate" comes from Latin "ventilare", meaning to fan or expose to air, built from "ventus", wind. That original sense of fanning or airing a space is still visible when the adjective is applied to the lungs and breathing, where it describes the mechanics of moving air in and out.

Synonyms: aerating, circulating
