This paper reports the results of spirometric studies done in the state of Gujarat in view of deriving the ventilatory norms. The study included a total of 2000 healthy nonsmoker individuals with 1369 males and 631 females. The study was done over the period from September, '92 to July, '93. The observations were tabulated, data fed on computers and the normal values for the parameters viz peak expiratory flow rate (PEFR), forced expiratory volume--1st second (FEV1) and forced vital capacity (FVC) were derived at.
