SESSION TITLE: Airways 4

SESSION TYPE: Original Investigation Poster

PRESENTED ON: Wednesday, October 26, 2016 at 01:30 PM - 02:30 PM

PURPOSE: Spiromety with any clinical indicators should be performed in an individual over age 40 to confirm COPD. These indicators include dyspnea, chronic cough, chronic sputum production and a history of exposure to risk factors in addition to family history of COPD. A fixed ratio of FEV1/FVC <0.7 is used as a spirometry criterion for airflow limitation. FEV1/FEV6 is suggested as an alternative for FEV1/FVC to determine airflow limitation. In this study, we explored the usefulness FEV1/FEV6 with portable spirometry device (COPD-6®,Vitalograph) to detect COPD in subjects with COPD indicators in primary care clinic.
