If the variability of the results can be diminished and the measurement accuracy can be improved, the range of normal values for Normal values for spirometry and gas transfer were derived using multivariate linear regression modelling and standard regression diagnostics. All statistical tests were two sided with a p-value of 0.05 taken to indicate statistical significance. Binomial 95% confidence intervals were calcu-lated for dichotomous variables. Normal adult value is averaged at 1200ml(20‐25 ml/kg) .It is indirectly measured from summation of FRC and ERV and cannot be measured by spirometry. In obstructive lung diseases with features of incomplete emptying of the lungs and air trapping, RV may be significantly high. 2012-06-05 · normal value indicates either a restrictive or a normal pattern.

NHANES Spirometry Normal Values. These NHANES 1999 regressions are recommended for ethnically appropriate individuals by the ATS/ERS Task Force:2005 ‘Standardization of Lung Function Testing’. They are used all over The Americas and elsewhere. The tables below are for mean normal value (Predicted) and the Lower Limit of Normality (LLN). mean of 0 and an SD of 1. The lower limit of normal is ofﬁcially deﬁned as the ﬁfth percentile of the distribution that corresponds to a z score of 21.64 (1, 3).

Predicted normal values for FEF can be calculated and depend on age, sex, height, mass and ethnicity as well as the research study that they are based on. Normal; 2000 to 3200 ml. 1 Expiratory reserve volume (ERV): It is the maximum volume of air which can be expired over and above a normal tidal expiration with a maximum expiratory effort.
