Pulmonology focuses specifically on the pulmonary system. The pulmonary system, also sometimes called the respiratory system, consists of the lungs, trachea, bronchi, bronchioles, associated blood vessels, and all other components involved in and directly related to breathing and the process of respiration (gas exchange).

Diagnosis of pulmonary diseases such as asthma, chronic obstructive pulmonary disease (COPD), or pulmonary hypertension

• Analyzing a variety of medical tests, imaging tests such MRI & CT scans
• Following and managing the course of disease in people with asthma, COPD, or other respiratory diseases
• Prescribing medications, such as inhalers or steroids to help manage respiratory disease
• Prescribing interventions, such as the administration of oxygen for the management of respiratory disease
• Performing procedures, such as obtaining biopsies of the lungs or the insertion of chest tubes
• Managing critically ill patients who require mechanical ventilation
