Introduction

Pulmonology is a specialized field of medicine that focuses on the respiratory system. This system, comprising the lungs, airways, and related structures, plays a crucial role in gas exchange-providing oxygen to the body while expelling carbon dioxide. Pulmonologists diagnose and treat conditions affecting the respiratory system, ranging from common diseases like asthma and Chronic Obstructive Pulmonary Disease (COPD) to more complex and rare conditions like interstitial lung diseases and pulmonary hypertension. This article explores the field of pulmonology, discussing the anatomy and physiology of the respiratory system, common diseases, diagnostic techniques, treatment modalities, and recent advancements in the field. The respiratory system is divided into two primary regions: the upper and lower respiratory tracts. The upper respiratory tract includes the nose, nasal cavities, pharynx, and larynx. The lower respiratory tract comprises the trachea, bronchi, bronchioles, and lungs. The lungs are the central organs of the respiratory system, responsible for gas exchange. The right lung has three lobes, while the left lung has 2, accommodating the heart’s position.^1,2 Within the lungs, the bronchi further divide into bronchioles, leading to the alveoli, where oxygen and carbon dioxide are exchanged with the blood. Breathing is controlled by the diaphragm and intercostal muscles.

Description

The diaphragm contracts and moves downward during inhalation, increasing the thoracic cavity’s volume and allowing air to enter the lungs. During exhalation, the diaphragm relaxes, forcing air out. Understanding the physiology of respiration is essential in pulmonology. The primary function of the lungs is to maintain oxygenation and remove carbon dioxide. Any disruption in this process can lead to respiratory failure, a critical condition that requires immediate medical attention. Pulmonologists treat a broad spectrum of respiratory diseases. These diseases can range from acute, self-limiting conditions to chronic, life-threatening disorders. Asthma is a chronic inflammatory disease of the airways that leads to airway narrowing and bronchospasm, causing symptoms such as wheezing, shortness of breath, and chest tightness. It is often triggered by allergens, exercise, or environmental pollutants. The pathophysiology involves bronchial hyperresponsiveness, inflammation, and mucus production. Asthma is a major public health concern, affecting over 300 million people globally. Treatment typically involves the use of bronchodilators (e.g., shortacting beta-agonists) for acute symptoms and inhaled corticosteroids to reduce chronic inflammation. COPD is a progressive disease characterized by airflow limitation that is not fully reversible. It primarily includes chronic bronchitis and emphysema.^3,4 Smoking is the leading cause of COPD, but other risk factors include air pollution and genetic predispositions, such as alpha-1 antitrypsin deficiency.

Conclusion

Patients with COPD suffer from chronic cough, sputum production, and dyspnea. As the disease progresses, exacerbations become more frequent, leading to hospitalization and increased morbidity. Treatment focuses on smoking cessation, bronchodilator therapy, corticosteroids, and oxygen supplementation for severe cases. Pulmonary fibrosis is part of a broader group known as Interstitial Lung Diseases (ILDs). It involves scarring of the lung tissue, leading to stiffened lungs and reduced respiratory capacity. Idiopathic Pulmonary Fibrosis (IPF) is the most common form of this disease, with an unknown cause. Patients with pulmonary fibrosis experience shortness of breath, a dry cough, and fatigue. Treatment options are limited but include antifibrotic agents such as pirfenidone and nintedanib, which can slow disease progression.
