Standard values of screening tests of pulmonary functions for male Egyptian workers

ABSTRACT

Forced expiratory volume and flow were measured in 600 healthy male Egyptian manual workers using techniques and equipment that meet the American Thoracic Society [ATS] recommendations. Linear regression equations using age and height alone predicted the spirometric parameters as well as more complex equations using additional variables. The present study produced standard values for forced vital capacity [FVC], forced expiratory volume in one second [FEVI], peak expiratory flow rate [PEF] and mid expiratory flow rate [FEF 25- 75]. The obtained values are lower than those derived from European populations. The observed differences could be of ethnic origin. Thus, the standard spirometric values obtained from the present study were recommended for use to evaluate Egyptian male manual workers instead of the European standards
