EFFECT OF ALTITUDE ON SPIROMETRIC VALUES

Mohammad Ayub, Mohammad Daud, Ahmed Badar, Farrukh A. Khan, Nusrat Waqar

Abstract


ABSTRACT:
A total of 132 healthy male subjects from Haripur, Abbottabad and Nathiagali were tested for
their lung volumes and flow rates. The spirometric values from Haripur and Abbottabad are
comparable to other studies carried out in Pakistan. It was found that there were no significant
differences in FEV1 and FEV1 /FVC% of the subjects but the FVC of the subjects from Nathiagali
was found to be significantly higher than the lowlanders. Moreover, the rate of decline in the lung
volumes and especially the flow rates of the subjects from Nathiagali was higher than the
lowlanders. Further insight in the problem is suggested.
