Reference values for spirometric variables for allegedly healthy workers

Spirometric reference values in healthy, non-smoking, urban Pakistani population.

OBJECTIVE To estimate the lung function prediction equation and to calculate appropriate normal reference values for the Pakistani adults living in Karachi. METHODS Predicted equations for normal lung functions were derived from 504 healthy non-smoking subjects including 321 males and 183 females aged 15-65 years. The subjects underwent measurement of spirometric flow and volume. The followin...

Spirometric reference values for healthy adults in the Mazandaran province of Iran.

OBJECTIVE One of the major issues in the use of spirometry is the evaluation of the values obtained in comparison with standardized reference values. Such reference values should be determined by studying populations similar to the population in which they are intended to be used. Considering the anthropometric differences among races and the effect of regional issues, such as climate and air q...

Predictive equations for spirometric reference values in a healthy adult suburban population in Tanzania

This study was conducted in Kinondoni district, Dar es Salaam, Tanzania, with the objectives to generate prediction equations for forced expiratory volume in 1 second (FEV1), forced expiratory volume in 6 seconds (FEV6), FEV1/FEV6 ratio and peak expiratory flow (PEF) from a nonsymptomatic sample of the population, and to compare these equations to published reference values. The study included ...

Spirometric reference values for an adult Rwandan population. (East Africa)

Spirometric reference values for an East-African population.

BACKGROUND Accurate interpretation of lung function testing requires appropriate reference values. Unfortunately, few African countries have produced spirometric reference values for their populations. OBJECTIVES The present study was carried out in order to establish normal lung function values for subjects living in Rwanda, East Africa. METHODS The study was conducted in Kigali, capital o...
