Peak Expiratory Flow Rates Values in Workers of Zeal-Pak Cement Factory Hyderabad, Pakistan

3 Abstract: This descriptive study of six months was conducted at Zeal Pak cement Factory workers and observed the different peak expiratory flow rates values in workers of Zeal Pak Cement Factory Hyderabad. The inclusion criteria of the study were all workers above 18 years and the workers were guided for PEF meter. 100 workers were registered in the study. All the workers were divided into 2 groups according to duration of exposure in industry. The Group-I comprised 4 to 12 years of dust exposure, Group-II was 13 to 20 years of dust exposure. Initial decrease in peak expiratory flow rate was 80.8 L/M. The total difference during year was 10.67 L/M. 70 workers belonged to Group-II mean exposure of dust was 16.91 years. Initial decrease in peak expiratory flow rate was 154.41 L/M and difference during one year was 9.34 L/M. This study concluded that PEFR recording in factory workers discovers loss of functional elements in lungs and increased duration of exposure of various dusts in industry leads to increased chances of lung diseases.
