Precision and accuracy of FEV1 measurements from the Vitalograph copd-6 mini-spirometer in a healthy Ugandan population.
<h4>Objective</h4>Evaluate the accuracy and precision of the copd-6 mini-spirometer for FEV1 in a rural Ugandan population.<h4>Methods</h4>In a cross-sectional study, 171 smallholder farmers performed spirometry with copd-6, and a diagnostic-quality spirometer.<h4>Resul...

| Sumario: | <h4>Objective</h4>Evaluate the accuracy and precision of the copd-6 mini-spirometer for FEV1 in a rural Ugandan population.<h4>Methods</h4>In a cross-sectional study, 171 smallholder farmers performed spirometry with copd-6, and a diagnostic-quality spirometer.<h4>Results and discussion</h4>The copd-6 underestimated FEV1 at low flows and overestimated FEV1 at high flows. Across all participants, the device slightly overestimated FEV1 by 0.04 [0.02; 0.06] L. Calibration data showed similar patterns.<h4>Conclusion</h4>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. |
