Obstrutivo

Obstrutivo is a Portuguese adjective used to describe something that relates to obstruction, or that causes obstruction, blockage, or narrowing of a passage, duct, or pathway. It is common in medical, technical, and scientific vocabulary and can refer to processes, conditions, or structures that impede function or flow.

Etymology and agreement: the term derives from the verb obstruir (to obstruct) and the suffix -tivo, formed in analogy with other adjectives from Latin roots. The masculine form is obstrutivo, the feminine is obstrutiva, and the plural forms are obstrutivos or obstrutivas, depending on gender.

Medical usage: in medicine, obstrutivo is frequently used to describe diseases or conditions that involve obstruction of airways or bodily passages. Examples include doença obstrutiva das vias aéreas (obstructive airway disease) and doença pulmonar obstrutiva crônica, commonly known as COPD, where obstruction of airflow is a key feature. Other conditions such as apneia obstrutiva do sono (obstructive sleep apnea) also employ the term to highlight the obstructive nature of the disorder. The adjective can also modify signs, imaging findings, or anatomical structures that show obstruction, such as lesão obstrutiva or alteração obstrutiva em um ducto.

Other contexts: obstrutivo can be used beyond medicine to describe any component, process, or effect that blocks or hinders progression, flow, or movement within a system, such as ducts, channels, or mechanical assemblies. In such uses, the emphasis remains on obstruction as a limiting factor.

Overall, obstrutivo functions as a precise qualifier for obstruction-related concepts in Portuguese.
