Overview

Pulmonology, also called respiratory medicine, is the medical specialty concerned with the structure, function and diseases of the respiratory system. It covers the lungs, airways, pleura, chest wall and respiratory muscles, and extends to the management of respiratory failure and sleep-related breathing disorders. Physicians who practice in this field are known as pulmonologists.

Scope and specialties

The specialty ranges from outpatient care for chronic conditions to acute management in intensive care units. Subspecialty areas include interventional pulmonology (bronchoscopic procedures), pediatric pulmonology, sleep medicine, and pulmonary rehabilitation. Pulmonologists often collaborate with thoracic surgeons, radiologists, pathologists and respiratory therapists.

Common conditions

  • Asthma and chronic obstructive pulmonary disease (COPD)
  • Pneumonia and other respiratory infections
  • Interstitial lung diseases and pulmonary fibrosis
  • Pulmonary embolism and pulmonary hypertension
  • Lung cancer and pleural diseases

Diagnosis and tests

Assessment typically combines clinical evaluation with physiological testing and imaging. Key tools include spirometry and other pulmonary function tests, chest radiography and CT scanning, bronchoscopy for direct visualization and biopsy, arterial blood gas analysis for gas exchange, and sleep studies for breathing disorders during sleep.

Treatment, prevention and rehabilitation

Treatment options vary by disease and may include inhaled and systemic medications, antibiotics, anticoagulation, oxygen therapy, noninvasive and invasive mechanical ventilation, and bronchoscopic or surgical interventions. Preventive measures include smoking cessation, vaccination and occupational exposure control. Pulmonary rehabilitation and patient education are important for improving function and quality of life.

Training, research and notable distinctions

Pulmonologists usually complete internal medicine training followed by a dedicated fellowship in respiratory medicine. Research spans basic lung biology, clinical trials of therapies, epidemiology of respiratory diseases, and development of devices and procedures. Pulmonology focuses on lungs and breathing; it overlaps with but is distinct from cardiology, which addresses heart diseases, and from respiratory therapy, which delivers technical support and therapies under clinical direction.

Importance

Because respiratory diseases are a major cause of illness worldwide, pulmonology plays a central role in acute hospital care and long-term disease management. Early diagnosis, evidence-based treatment and multidisciplinary care can reduce symptoms, prevent complications and improve outcomes for people with breathing disorders.
