Abstract
OBJECTIVE: To understand the effects of airborne pollution on cardiopulmonary function in healthy person. METHODS: 15 healthy workers were selected from heavily polluted area as the experimental group (EG) and 15 healthy workers were selected from relatively clean area as control group (CG). The blood pressure were measured with sphygmomanometer and the vital capacity (VC) were detected with FHL-II type spirometer at rest status. Cardiopulmonary functions in different exercise states were measured by using the cardiopulmonary exercise testing (CPET). RESULTS: It showed that heart rate of EG was more higher than those of the CG at rest status (P < 0.01), and VC was more lower than those of the CG (P < 0.05). While the load increased to AT, the results of VO2, VO2/kg, O2P and METS in CG were more higher than these indexes in EG (P < 0.05, P < 0.01) . While the load increased to VO2 max, the results of VO2 max, VO2 max/kg, O2P, METS and DT in CG were more higher than these indexes in EG (P < 0.01), and the recovery of heart rate in EG was slow in comparison with CG. CONCLUSION: Airborne pollution could have adverse effects on the cardiopulmonary function, reserve ability and function potential. The chronic adverse effects of airborne pollution on the health could be easy to reflect at static state. Therefore CPET could roundly evaluate the damage of airborne pollution to cardiorespiratory function.
