The objective of the research study was to assess the respiratory symptoms and the lung function profile among enclosed parking-garage personnel in different establishments in Cebu City. Thirty (30) enclosed parking-garage personnel were selected through purposive sampling technique. The American Thoracic Society and National Heart and Lung Institute-Division of Lung Disease Respiratory Questionnaire (ATS-DLD-78-A) was utilized in the study to identify the prevalence of respiratory symptoms among the respondents. Also, a Medical International Research (MIR) Spirobank G portable spirometer was used to quantify the presence or absence of lung impairment.
Through the use of American Thoracic Society and National Heart and Lung Institute-Division of Lung Disease Respiratory Questionnaire, results showed that most of the respondents experienced cough (53%), breathlessness (43.3%), chest illnesses (43.3%), phlegm (36.7%), wheezing (36.7%) and cough and phlegm (13.3%). The 30 enclosed parking-garage personnel in different establishments were categorized by the duration of working years of exposure with 10 respondents in each of the category, less than one (1) year, one (1) to three (3) years and more than three (3) years. Forced Expiratory Volume in One Second, Forced Vital Capacity, Forced Expiratory Volume in One Second/Forced Vital Capacity ratio and Peak Expiratory Flow were used to measure the lung function of the respondents and further assess the relationship to the respondent's toxic fumes exposure and respiratory symptoms. About 66.7% showed normal FEV1, mild FEV1 revealed 13.3%, moderate FEV1 presented 6.7% and 3.3% with severe FEV1. Forced Vital Capacity was also tested, 60.0% had a normal FVC, 23.3% with mild FVC level, 13.3% had moderate FVC and 3.3% with severe FVC. FEV1/FVC ratio was measured and only 3.3% showed abnormal result and the rest, 96.7% belonged to normal level. Lastly, PEF was presented; 73.3% with normal, 20.0% with mild and 6.7% with severe. With the use of Spearman's Rho Correlation, no relationship was shown between the years of toxic fumes exposure and the lung function profile of the respondents. Although, most of the results showed to have no relationship between respiratory symptom and lung function profile, a moderate negative relationship was seen between the respiratory symptom chest illness with the FEV1 and FVC parameter. Even though majority of results showed no relationship, the outcomes should not be neglected for minority of the respondents.
Parking-garage personnel from other establishments in Cebu City should be considered in parallel to broaden the scope of the respondents and be able to determine differences or improvement from this study. Lung function measurement with the use of spirometer before working hours and after working hours of respondents may be done to assess for changes in pulmonary function with such exposure to toxic fumes. Furthermore, this study may be used by future researchers as a reference in formulating a new study with the correlation of duration of toxic fumes exposure and respiratory symptoms to lung function.
