A study to detect early lung function deterioration using forced oscillation technique in smokers

Background: Scientists unequivocally evidenced that tobacco consumers suffer from three Ds: disease, disability, and death. The forced oscillation technique (FOT) is a non-invasive method with which to measure respiratory mechanics. Aims and Objectives: This study was done to evaluate the ability of FOT to detect early smoking-induced respiratory function deterioration and to compare the performance of FOT with spirometry in healthy smokers. Materials and Methods: A cross-sectional study was conducted at a medical college between January 1st, 2021, and June 31st, 2022, with a sample size of 30. Study participants included healthy smokers and non-smokers. Spirometry and FOT were taken into consideration as a diagnostic modality. Data analysis was done through statistical software with a confidence interval of 95% and P
