AIM: Portable spirometers are useful and convenient for evaluating obstructive lung disorders by measuring the forced expiratory volume in one second (FEV1)/FEV6 and identifying possible chronic obstructive pulmonary disease (COPD) patients.
METHODS: FEV1/FEV6 and FEV1/forced vital capacity (FVC) of 96 consecutive inpatients were measured using Hi-Checker and the conventional spirometer, respectively.
RESULTS: The average (range) age was 67 (28-90) years old. The number of current- and ex-smokers/non-smokers was 67/29, respectively. The correlations between the values of FEV1, FEV1/FEV6 and FEV1/FVC and the “lung age” measured by both the portable and the conventional spirometer were assessed. Results: A significant correlation was observed between the FEV1 and the “lung age” values measured using both methods. The FEV1/FEV6 measured using Hi-Checker and the FEV1/FVC measured using the conventional spirometer were also significantly correlated (r=0.846).
CONCLUSION: Hi-Checker is useful and convenient for checking FEV1 and FEV1% as a substitute for conventional spirometers.
