A Physician Pulmonologist is a medical doctor who specializes in diagnosing and treating diseases of the respiratory system, including the lungs and airways. They manage conditions such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer. Pulmonologists may work in hospitals, clinics, or specialized respiratory centers, often collaborating with other healthcare professionals. They use diagnostic tools like pulmonary function tests, bronchoscopy, and imaging to assess lung health and develop treatment plans. Additionally, they may provide critical care for patients with severe respiratory issues, including those in intensive care units.
