Precision and accuracy of FEV(1) measurements from the Vitalograph copd-6 mini-spirometer in a healthy Ugandan population

OBJECTIVE: Evaluate the accuracy and precision of the copd-6 mini-spirometer for FEV(1) in a rural Ugandan population. METHODS: In a cross-sectional study, 171 smallholder farmers performed spirometry with copd-6, and a diagnostic-quality spirometer. RESULTS AND DISCUSSION: The copd-6 underestimated...

description OBJECTIVE: Evaluate the accuracy and precision of the copd-6 mini-spirometer for FEV(1) in a rural Ugandan population. METHODS: In a cross-sectional study, 171 smallholder farmers performed spirometry with copd-6, and a diagnostic-quality spirometer. RESULTS AND DISCUSSION: The copd-6 underestimated FEV(1) at low flows and overestimated FEV(1) at high flows. Across all participants, the device slightly overestimated FEV(1) by 0.04 [0.02; 0.06] L. Calibration data showed similar patterns. CONCLUSION: The copd-6 could be considered as an affordable tool for research on lung function impairment in resource-constrained settings. However, further validation in a study population with obstructive lung disease is needed.
