Pulmonology
Doctor Title: Pulmonologist
Diagnoses and treats diseases of the lungs and respiratory system, asthma, COPD, and sleep apnea.
What Does a Pulmonologist Do?
Pulmonology is the medical specialty devoted to the respiratory system. Pulmonologists specialize in structural, infectious, inflammatory, and neoplastic diseases of the airways and lung parenchyma, managing everything from chronic asthma and COPD to pulmonary fibrosis, interstitial lung diseases, and sleep-disordered breathing.
Core Clinical Responsibilities:
- Interprets pulmonary function tests (spirometry, lung volumes, diffusion capacity DLCO).
- Performs diagnostic and therapeutic bronchoscopy to view bronchial airways and collect biopsies.
- Manages advanced respiratory pharmacotherapy including inhaled bronchodilators, biologics, and antifibrotics.
- Interprets overnight sleep studies (polysomnography) and prescribes CPAP/BiPAP therapy for sleep apnea.
- Oversees mechanical ventilation and oxygen therapy in intensive care units.
When to See a Pulmonologist
You should consider scheduling an evaluation with a Pulmonologist if you experience any of the following warning signs or persistent symptoms:
Chronic cough lasting longer than 8 weeks with or without sputum production
Progressive shortness of breath on exertion, climbing stairs, or at rest
Audible wheezing or chest tightness when breathing or exposed to cold air
Coughing up blood or blood-streaked mucus (hemoptysis - seek prompt evaluation)
Severe loud snoring, gasping for breath at night, and persistent daytime sleepiness
Unexplained low blood oxygen readings (SpO2 below 92%) on a pulse oximeter
Conditions & Diseases Treated
A Pulmonologist provides specialized diagnostic workups and therapeutic management for a wide range of conditions, including:
Common Tests & Procedures Ordered
To confirm diagnoses and monitor treatment effectiveness, a Pulmonologist frequently utilizes the following clinical tests and procedures:
Comprehensive Spirometry & Pulmonary Function Testing (PFT)
Quantifies forced expiratory volume (FEV1), vital capacity, and airway reversibility with bronchodilators.
High-Resolution Chest Computed Tomography (HRCT)
Detailed cross-sectional imaging identifying ground-glass opacities, fibrosis, and early lung nodules.
Flexible Fiberoptic Bronchoscopy
Endoscopic visualization of tracheobronchial tree with bronchoalveolar lavage (BAL) and biopsy capabilities.
Overnight Polysomnography (Sleep Study)
Continuous monitoring of brain waves, airflow, respiratory effort, and blood oxygen during sleep.
D-Dimer Blood Test

Subspecialties & Advanced Fellowships
Within Pulmonology, physicians may pursue additional fellowship training to concentrate on specialized surgical procedures or disease subsets:
Frequently Asked Questions
Make the most of your consultation with a Pulmonologist by coming prepared:
- Bring all currently prescribed inhalers, spacers, nebulizer solutions, and home oxygen settings.
- Avoid taking short-acting bronchodilators (e.g., albuterol) on the morning of a pulmonary function test unless in respiratory distress.
- Bring previous chest X-ray and CT scan discs along with written radiologist reports.
