Abstract

Background: Indonesia has the highest number of adolescent smokers in the world. Carbon monoxide (CO) is a by-product of tobacco smoking and is inhaled into the lungs. A smokerlyzer can monitor its level. Cigarette smoke also causes inflammation that affects airflow in the airways and can be detected by measuring the peak expiratory flow rate (PEFR). This study aims to determine the relationship between smoking and CO levels and PEFR in high school students in Banda Aceh City.Methods: This quantitative study uses an analytical observational approach with a cross-sectional design. This study involved 300 students from five senior high schools in Banda Aceh. The data were analyzed using the Mann-Whitney and Spearman test with a significance value <0.05.Results: CO levels of the smoker students were higher (12.61 ± 3.342 ppm) than nonsmoker students (2.46 ± 0.569 ppm), p=0.000. The average PEFR for smoking students was lower than nonsmokers (61.11 ± 9.163%) than for non-smoking students (78.48 ± 6.804 %), p=0.000. Duration of smoking in smoking students was also strongly associated with CO levels and PEFR (r=+0.749, p=0,000, r=-0.560, p=0.000, respectively).Conclusion: There is a relationship between smoking and CO levels and PEFR in senior high school students in Banda Aceh.

Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a global health concern defined by persistent respiratory symptoms and irreversible airflow blockage. Excess mucus production and decreased ciliary function in mucus elimination are two of the most common issues among COPD patients. Chest therapy is a physiotherapy practice that helps to remove mucus in a variety of acute and chronic respiratory illnesses. Objective: The study aims to explore how chest treatment affects symptoms and lung function in patients with COPD exacerbations. Methods: This study employed a one-group pretest-posttest design, selecting a sample of 30 COPD exacerbation patients from dr. Zainoel Abidin Hospital through convenience sampling technique. Chest therapy was administered consecutively over six days. Pulmonary function was assessed with a peak flow meter, while symptom improvement was assessed through the BORG questionnaire, Modified Medical Research Council (mMRC) scale, and COPD Assessment Test (CAT). Data analysis was performed using the paired T-test and Wilcoxon test. Results: Chest therapy increased average peak expiratory flow (PEF) by 6.40 L/min, from 29.20 ± 6.26 L/min to 35.60 ± 7.65 L/min. BORG scale scores were likewise reduced, with the majority shifting from scale 4 (56.7%) to scale 2 (40%), as were mMRC scores, which decreased from a dominant scale 3 (40%) to scale 2 (33.3%). Furthermore, CAT scores shifted from the high category (76.7%) to the moderate category (53.3%). Bivariate tests revealed that chest therapy had a significant effect on rising PEF values (P<0.001), decreasing BORG scale scores (P<0.001), and decreasing CAT scores (P = 0.001), but no significant effect was seen on the mMRC scale (P = 0.564). Conclusions: Chest therapy positively impacts lung function, as shown by increased peak expiratory flow (PEF) values and improved clinical symptoms of COPD exacerbation, as measured by BORG and CAT scale scores.
