[Study on predictive value of pulmonary ventilation function of healthy coal mine workers].
OBJECTIVE
To establish the predictive value of pulmonary ventilation function for dust-exposed-workers in some coal mine.


METHODS
From March to August in 2011, 2994 coal workers were involved in the research, their pulmonary ventilation function were examined by pulmonary function measuring instrument. 1389 worker's pulmonary ventilation function were normal, the data of 1139 workers established the predictive value equation, and those of 250 workers tested the equation.


RESULTS
Age was negatively correlated with FVC, FEV1, FEV1%, MMF and PEFR (P < 0.05). Height was negatively correlated with FEV1%, however, it was positively correlated with others (P < 0.05). Weight was negatively correlated with MMF and positively correlated with FVC and PEFR (P < 0.05). The regression equation of the predictive value was established by age, height and weight as in dependent variables. It were above 90% that the accordance ratio to test the equation by original data and test data. Predictive value of pulmonary ventilatory function from predictive value equation were lower than that of lung fucntion machine (P < 0.05).


CONCLUSIONS
Predictive value of pulmonary ventilatory function from predictive value equation was superior to that of lung fucntion machine.
