What is a Pulmonologist and How Can They Help You?

A pulmonologist diagnoses and treats respiratory system diseases affecting lungs and airways. These specialists manage breathing disorders, pulmonary pathology, and critical respiratory care.

Pulmonologists complete medical school, a three-year internal medicine residency, and a two- to three-year pulmonary medicine fellowship. Many complete combined pulmonary-critical care training, with some pursuing interventional pulmonology or sleep medicine.

A Pulmonologist's clinical duties include:

  • Specializes in pulmonary function, airway health, and respiratory mechanics
  • Conducts respiratory function testing, bronchoscopic examinations, sleep evaluations, and chest imaging interpretation
  • Manages bronchial asthma, chronic obstructive disease, pneumonic infections, interstitial lung disease, pulmonary malignancies, sleep breathing disorders, and respiratory compromise
  • Employs inhalation therapies, biologic agents, bronchoscopic techniques, supplemental oxygen, and ventilatory support
  • Alternative names: respiratory specialist, pulmonary physician, lung specialist, MD, DO
