Back ground: Wood workers are more prone to exposed wood dust on regular basis. They are more prone to develop occupational lung diseases. PFT among such workers describe prognosis of such occupational hazards of wood dust. Aim: Based on such back ground we have conducted PEFR, FEV1/FVC and MVV among wood factory workers and compared with healthy individuals. Methods: Present study was carried out at Shree M P Shah Medical College, Jamnagar. We have used MEDSPIROR to collect PFT data in wood workers. Result: Wood workers have significant low PEFR (4.6±0.34), FEV1/FVC (87.98±3.66) and MVV (75.02±3.6) as compare to healthy individual. Prolonged exposure to wood dust in workers shows declining of PFTs.
