Abstract: Pulmonary function testing is a physiological test that measures the air volume that an individual inhales or exhales as a function of time. Smoking is greatly associated with reduction of pulmonary function. The aim of the present study was thus to estimate forced expiratory volume in first second (FEV1), forced vital capacity (FVC), and maximum voluntary ventilation (MVV) in adults aged ≥ 40 years with smoking history. Smoking is often related to obstructive disorders, as indicated by low FVC, FEV1, and MVV values. These pulmonary functions were analyzed based on several variables, such as number of cigarettes smoked per day, smoking duration and age. The study sample comprised of 100 healthy adult smokers. All participants were interviewed to obtain information related to their lifestyle and smoking habit. After analyzing the FVC, FEV1, and MVV results using SPSS software, we noted that their values were conversely related to participant age and smoking duration.
