Pulmonology

Lore & Background

One of the first major discoveries relevant to pulmonology was the discovery of pulmonary circulation. Thirteenth-century anatomist Ibn Al-Nafis accurately theorized that blood must pass through the pulmonary artery, through the lungs, and back into the heart, disproving the earlier theory of Galen that blood passed through pores in the heart's septum. This is believed by many to be the first scientific description of pulmonary circulation. Although pulmonary medicine only began to evolve as a medical specialty in the 1950s, William Welch and William Osler founded the 'parent' organization of the American Thoracic Society, the National Association for the Study and Prevention of Tuberculosis. The care, treatment, and study of tuberculosis of the lung is recognized as a discipline in its own right, phthisiology. Pulmonologists are specially trained in diseases and conditions of the chest, particularly pneumonia, asthma, tuberculosis, emphysema, and complicated chest infections. They often perform specialized procedures such as bronchoscopy and pleuroscopy, and many are certified to practice critical care medicine simultaneously.

Reader's Guide

Pulmonology holds significant importance as a medical specialty that addresses a wide range of respiratory conditions, from common infections like pneumonia to chronic diseases such as asthma and emphysema. Its relevance extends into critical care medicine, as pulmonologists frequently manage patients requiring mechanical ventilation and life support. The field's historical foundation includes the early understanding of pulmonary circulation by Ibn Al-Nafis, which corrected long-held misconceptions. The specialty evolved formally in the 1950s, building on earlier work in tuberculosis care. Pulmonology's diagnostic toolkit includes physical examination, spirometry, bronchoscopy, and imaging such as chest X-rays and CT scans. Treatment primarily involves medication, including inhalers and oral drugs, as well as oxygen therapy and mechanical ventilation when needed. Pulmonary rehabilitation, a multidisciplinary approach, aims to improve patients' quality of life and independence. The field also encompasses interventional pulmonology, a relatively new area using procedures like bronchoscopy and pleuroscopy. Pulmonologists collaborate closely with cardiothoracic surgeons and cardiologists, and their training in the United States typically involves internal medicine residency followed by a fellowship in pulmonary medicine, often combined with critical care medicine.
