Ventilatory pulmonary function study in healthy young Nigerian adults

Ventilatory pulmonary function was studied in 108 healthy young Nigerian adults using an electronic spirometer, with a view to determining the normal values of function for healthy Nigerians. The measured values of forced vital capacity, forced expiratory volume in 1 sec, maximum voluntary ventilation, and peak flow rate were compared with those obtained from similar studies on Nigerians and the predicted values for Caucasians. Higher values of function were obtained in Nigerian males than in the females. Nigerian males, however, showed lower values when compared with Caucasians of similar anthropometric measurements; there was no difference between the females in this study and their Caucasian counterparts. There were also some similarities and differences between the values obtained in this study and those of similar studies in Nigerians of different socio-ethnic backgrounds. The results emphasize the necessity for a ventilatory normogram for each socio-economic or ethnic grouping of individuals.
