Aim: The aim of the study was to evaluate expiratory flows in smoker or non-smoker obese patients who underwent elective surgery.
Material & Method: The ages, weight and height, BMI, smoking status, pulmonary function test (FVC, FEV 1, PEF, FEV 25/75, FEV 25, FEV 50, FEV 75, FEV 1/ FVC) values of the morbidly obese patients who admitted to the Anesthesiology polyclinic were recorded.
Results: Of the 16 patients who smoker, BMI: 39.87 ± 5.42 and non-smoker 24 patients had BMI: 40.28 ± 5.17, no statistically significant difference was found between the two groups. When the parameters of the respiratory function tests were evaluated, the values of the patients who were smoker were found to be lower than those who were non-smoker and there was a statistically significant difference.
Conclusion: In our study, tests showed that smokers had lower FEV1/ FVC than non-smokers. In conclusion, in obese patients, smoking adversely affects pulmonary function tests.
