Abstract

Background: Pilot works in the high environment that exposed by G force. Increasing G force led to linear decreases in cardiac output and blood oxygenation of the brain. Thus, likely due to decreased lung gas exchange capacity in hypergravity. This study aims to investigate the pulmonary diffusing capacity test among Fighter pilots in Madiun. Methods: This study used cross sectional method conducted on February 2019 in Madiun. The total subjects consist of 44 Fighter pilots based on total sampling. Interview was done to fill out question about sociodemografic and smoking habit, flight hour data and physical fitness. Lung function measurement was done using portable spirometry and DLCO equipment (Easyone TM Pro Lab). Result: Spirometri result was found in the standard normal range in 41 subjects (93,2%) only 3 subject (6,8%) get obstruction abnormalities and none of them get restriction result. Average VEP1 prediction was 103,3±10,60 % and median range for VEP1/KVP was 84,5(63,5-92,5) %. Lung diffusion capacity measurement was found to be normal in 41 subject (93,2%) and to be deficient in 3 subject (6,8%) in smoker. Conclusion: This study demosntrated that diffusion capacity and spirometry test in Fighter pilots generally in normal range. Lung diffusion capacity has no association with age, BMI, flight hour, physical fitness, Brinkman index and spirometry parameters. (J Respir Indo. 2020; 40(1): 39-47)

Abstract

Background: Although COPD has been believed to be characterized by respiratory disease, there are currently limited study conducted to evaluate inflammation markers and exacerbation rate in COPD by noninvasive methods. We did a prospective cohort study to observe the alteration of Neutrophyl-Lymphocyte Ratio (NLR) and C-reactive protein (CRP) in COPD patients to find any possible correlation with COPD exacerbation status. Method: From July to December 2018, a prospective cohort study was performed with blood and spirometry test on 31 COPD patients during exacerbation (AE-COPD) and stable. The mean of NLR and CRP were compared and analyzed. Results: Both NLR and CRP decreased during stable condition (from 7.95±6.8 to 4.6±5.5 and 43.4±71 to 12.2±18.5) with P<0.01 respectively. We also found a significant inverse correlation between NLR and FEV1/FVC in AE-COPD and CRP showed an inverse correlation only with FEV1 in AE-COPD. Another interesting finding was a subject with very high CRP whose value remained above the nomal limit during stable, and died within 2 months after exacerbation. Conclusion: NLR and CRP levels in COPD patients increased during exacerbation, which may reflect lung function and exacerbation status.
