Abstract


To assess the changes in pulmonary functions in terms of respiratory frequency (f), tidal volume (VT), forced vital capacity (FVC), forced expiratory volume for first second (FEV1, maximum ventilatory volume (MVV) and peak expiratory flow rate (PEFR), on sudden exposure to high altitude, 16 healthy normal, non-smokers, lowland subjects (11 medical cadets mean age 20.18±1.44 yr and 5 jawans mean age 32.2±3.54 yr) were studied at low altitude (518 m) and on the first 3days at high altitude (4570 m). On exposure to high altitude significant decrease in VT (P< 0.05) FVC (P
