EFFECT OF ALTITUDE ON SPIROMETRIC VALUES
Abstract
ABSTRACT:A total of 132 healthy male subjects from Haripur, Abbottabad and Nathiagali were tested fortheir lung volumes and flow rates. The spirometric values from Haripur and Abbottabad arecomparable to other studies carried out in Pakistan. It was found that there were no significantdifferences in FEV1 and FEV1 /FVC% of the subjects but the FVC of the subjects from Nathiagaliwas found to be significantly higher than the lowlanders. Moreover, the rate of decline in the lungvolumes and especially the flow rates of the subjects from Nathiagali was higher than thelowlanders. Further insight in the problem is suggested.References
