espiratoria

Espiratoria is a Spanish term formed as the feminine of espiratorio, from the verb espirar (to breathe) with the suffix that yields adjectives and nouns related to a function or process. In contemporary usage, espiratoria is primarily an adjective meaning related to respiration or the respiratory system. It appears in technical or scientific texts in compounds describing breathing-related processes, devices, or phenomena, though in many contexts espiratorio or more common terms like respiratorio are preferred.

As a standalone noun, espiratoria is rare. When it does appear as a noun, it is typically in regional or older writings and often functions as a shorthand for a device or component associated with respiration. In standard modern medical and scientific vocabulary, exact terminology such as sistema respiratorio (respiratory system), equipo de soporte ventilatorio (ventilatory support equipment), or aparato respiratorio is generally used.

Etymology: from espirar, to breathe, plus the suffix -torio/-toria, yielding forms related to function or equipment.
