Lung function research focuses on understanding the respiratory system and how it functions in both healthy individuals and those with respiratory conditions. This area of study involves measuring lung capacity, airway resistance, and other respiratory parameters to assess lung health and function. Researchers in this field often investigate the impact of factors such as age, smoking, pollution, and disease on lung function, as well as explore ways to improve respiratory health through interventions such as rehabilitation programs or medications. Lung function research is critical for diagnosing and managing respiratory diseases such as asthma, COPD, and lung cancer.
