Background:
The tobacco epidemic is one of the greatest hazards to public health that the world has ever encountered.
Objective:
To evaluate correlation of neuropathy with advanced airflow obstruction due to chronic smoking.
Materials And Methods:
This research was conducted on 40 healthy male smokers and 40 healthy nonsmokers. Pulmonary function test was performed in all subjects with computerized spirometer (Spiro Excel-software version 1.1), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), peak expiratory flow rate, FEV1/FVC were recorded. Nerve conduction studies were performed using Neuroperfect Machine-"EMG, NCV, EP-Medicaid Machine 2000." Both the upper limbs and both lower limbs were tested for motor and sensory nerves study.
Results And Conclusion:
Frank neuropathy is not observed in healthy adult male smokers, but the dysfunction of peripheral nerves is observed and dysfunction increases as the pulmonary functions deteriorate. It was concluded that long before the emergence of clinical neuropathy, the deterioration in nerves and even lung functions could be diagnosed earlier by electrophysiological studies.

01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
