Evaluation of spirolabii spirometer for the assessment of lung function test

Abstract EN

This study was carried out on twenty normal subjects in order to evaluate (SpirolabII spirometer) for the estimation of lung function test.

Two processes where used for evaluation, the first is the systematic error to determine the accuracy of the device by comparison with the most accurate standard device (the vitalograph) and the second process is to test the random error or reproducibility of spirolabII.

The result of this study indicate that there were no significant differences in values of FEV1, FVC and FEV % measured by spirolabII with that measured by vitalograph.

More over the result of random error test indicate that the spirolabII is reproducible device which is proved by using the statistical equation (2SD / mean x 100 %) to determine 95 % tolerance limit of the device which indicate that the device is greatly reproducible.
