Correlation of Nitric Oxide (NO) Sputum Level and Lung Physiology of Indoor Parking Attendant

Background: Air contamination inside the building causes respiratory inflammation and increases NO sputum levels that cause changes in parking staffs’ lung physiology. Objective: To analyze the correlation between NO sputum level and lung physiology of indoor parking attendant. Method: This research was conducted at the Toserba oceans in Tasikmalaya West Java, Indonesia with a sample of 40 people. Twenty indoor parking attendants as an exposed group and 20 administrative officers as a control group. Sputum NO and lung physiology were examined in both groups. The measurement of NO sputum level was using Griess method and lung physiology was by spirometry of brand of Fukuda. Results: The mean of NO sputum level in the exposed group was 4689.75 ± 6778.452 and in the control group was 485.25 ± 307, the mean of NO level was obtained a significant difference between exposed group and control group (p = 0.009). The results of lung physiology examination in both exposure and control group from% FEV1,% FEV1 / FVC showed significant differences (p <0.05). While% FVC did not show a significant difference (p> 0.05). The result of the Pearson correlation test showed a strong positive correlation between NO sputum level and lung physiology of indoor parking attendant (r = 0.461 with p <0.041). Conclusion: There was a correlation between NO sputum level and lung physiology of indoor parking attendant.
