ekspiraatiossa

Ekspiraatiossa is a Finnish term used primarily in physiology and medicine to denote something occurring during expiration, the exhalation phase of breathing. The word is formed from ekspiraatio (expiration) with the inessive suffix -ssa, yielding the meaning “in expiration” or “during expiration.” In practice, ekspiraatiossa is used to specify timing of measurements, events, or processes tied to the expiratory phase.

In clinical and research contexts, ekspiraatiossa describes conditions or observations that take place while a person exhales. For example, a pulmonary function test might report certain parameters being assessed ekspiraatiossa to distinguish them from measurements taken during inhalation. The term appears in Finnish-language medical texts, textbooks, and articles dealing with respiratory physiology, ventilatory mechanics, and the pharmacokinetics of inhaled drugs.

Etymology and usage notes: Ekspiraatiossa derives from ekspiraatio, borrowing from the Latin expiratio, with the Finnish locative suffix -ssa. The form aligns with other respiratory terms such as inspiraatio (inspiration) and ekspiraatio (expiration). Its usage tends toward formal, technical writing.

See also: inspiraatio, ekspiraatio, hengitys, respiratorinen fysiologia, keuhkojen toiminta.

Notes: Ekspiraatiossa is a specialized term mostly found in professional Finnish texts. In everyday language, speakers may opt for clearer phrases like “aatto/ajankohta hengityksen uloshengityksen aikana” or simply refer to the phase of exhalation rather than using the term itself.
