Background: Systematic case identification has been proposed as a strategy to improve diagnosis rates and to enable the early detection of subjects with COPD. We hypothesized that case identification could be possible using the handheld spirometer Hi-CheckerTM . Aim: To determine how to modify the FEV1 /FEV6 values obtained using the Hi-CheckerTM to screen for cases with airflow limitation. Methods: Spirometry was performed with both an electronic desktop spirometer and with the Hi-CheckerTM in 312 male subjects. Results: The average FEV1 (mean ± SD) measured using a conventional spirometer and the Hi-CheckerTM was 2.99 ± 0.56L and 3.07 ± 0.57L, respectively. These results were significantly different (P
