Pulmonary function research focuses on studying the function of the lungs and respiratory system. This includes investigating how efficiently the lungs are able to take in and expel air, as well as measuring lung capacity, airflow, and gas exchange. Researchers in this field may study various respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and lung cancer, as well as the impact of environmental factors, genetics, and lifestyle on lung health. Pulmonary function tests are commonly used to assess lung function and diagnose respiratory diseases. Overall, pulmonary function research aims to improve our understanding of lung health and develop better strategies for diagnosing, treating, and preventing respiratory disorders.
