Clinical evaluation of breath sounds is the first and most common method of assessing lung health. The stethoscope placed on the back and chest lets the physician listen to the breath sounds. This process is called auscultation. Read more: What Is Breath Sound Assessment? Article

Pleural Effusion (Fluid in the Pleural Space)
Pleural effusion is a buildup of fluid in the chest or on the lungs. There are two types of pleural effusion, transudate and exudate. Causes of transudate pleural effusion include congestive heart failure, kidney failure, and cirrhosis. Exudate pleural effusion can be caused by malignancy (cancer) or lung infection. Typically, transudate pleural effusion is more easily treatable. Symptoms of pleural effusion include chest pain, pain when breathing, difficulty breathing, and cough. Treatment depends on the source or cause of the pleural effusion.
Pulmonary Embolism (Blood Clot in the Lung)
A pulmonary embolism (PE) occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery in the lung where it blocks the artery and damages the lung. The most common symptoms of a pulmonary embolism are shortness of breath, chest pain, and a rapid heart rate. Causes of pulmonary embolism include prolonged immobilization, certain medications, smoking, cancer, pregnancy, and surgery. Pulmonary embolism can cause death if not treated promptly.
Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due to tobacco smoke. Lung cancers are classified as either small-cell or non-small-cell lung cancers.
Smoker's Lung: Pathology Photo Essay
Smoker's lung photo essay is a collection of pictures and microscopic slides of lung disease caused by cigarette smoking. Smoker's lung refers to the diseases and structural abnormalities in the lung caused by cigarette smoking.
Collapsed Lung (Pneumothorax)
A pneumothorax is free air in the chest outside the lung, that causes the lung to collapse (collapsed lung). There are two types of pneumothorax, spontaneous or primary pneumothorax and secondary pneumothorax. Symptoms include sudden chest pain, shortness of breath, rapid heart rate, rapid breathing, cough, and fatigue.
Emphysema is a COPD (chronic obstructive pulmonary disease) that often occurs with other obstructive pulmonary problems and chronic bronchitis. Causes of emphysema include chronic cigarette smoking, exposure to secondhand smoke, air pollution, and in the underdeveloped parts of the world. Symptoms of emphysema include chronic cough, chest discomfort, breathlessness, and wheezing. Treatments include medication and lifestyle changes.
Small Cell Lung Cancer vs. Non-Small Cell Lung Cancer
Non-small cell lung cancers (NSCLC) consist of large cell carcinomas, adenocarcinomas, and squamous cell carcinomas. Small cell lung cancer (SCLC) usually starts in the bronchi and typically appears in those who smoke. SCLC and NSCLC are staged in different manners, and SCLC tends to metastasize more quickly than NSCLC. Signs and symptoms of NSCLC and SCLC include shortness of breath, coughing up blood, recurring lung infections, and chest pain. Treatment may involve radiation therapy, chemotherapy, and surgery.
Popcorn Lung (Bronchiolitis Obliterans)
Popcorn lung is a term for the lung disease bronchiolitis obliterans. Popcorn lung is caused by diacetyl and 2,3-pentanedione, chemicals used when manufacturing flavorings for food certain products like popcorn, coffee. E-cigarettes also may cause popcorn lung. Diacetyl and 2,3-pentanedione damage lung tissue that is irreversible. Symptoms of popcorn lung develop gradually over time. The main symptoms are chronic cough and shortness of breath. Other symptoms may include night sweats, weight loss, and fever. Symptoms of severe exposure to diacetyl and 2,3-pentanedione include inflammation of the skin, eyes, nose, and/or throat. Popcorn lung often resembles tobacco-related COPD (chronic obstructive pulmonary disease) so it often is difficult to diagnose. Lung biopsy and surgery may be necessary. There is no cure for popcorn lung. Life expectancy for a person with (bronchiolitis obliterans) depends upon how early the disease was diagnosed and level of exposure to diacetyl and 2,3-pentanedione.
Lung Anatomy (Structure and Function)
The lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
Interstitial Pneumonitis (Interstitial Lung Disease)
Interstitial lung disease refers to a variety of diseased that thicken the tissue between the lungs' air sacks. Viruses, bacteria, tobacco smoke, environmental factors, cancer, and heart or kidney failure can all cause interstitial lung disease. Shortness of breath, cough, and vascular problems are symptoms caused by interstitial lung disease, and their treatment depends on the underlying cause of the tissue thickening.
Nontuberculous Mycobacterial Lung Disease (NTM, Symptoms, Treatment, Side Effects)
Nontuberculous mycobacteria (NTM), most commonly, M. avium complex or MAC, is a mycobacteria that causes lung infections and disease. Nontuberculous mycobacteria are commonly found in soil, air, and water. Examples of how NTM lung infection are transmitted include swimming, using a hot tub (NTM bacteria are aerosolized), or playing with or handling soil. The most common symptoms of NTM lung infection are chronic, dry cough, and shortness of breath. Sometimes the cough may have mucous or blood. Other symptoms of NTM lung disease include fatigue, chest pain, malaise, and weakness. As NTM lung disease progresses, fevers, night sweats, and appetite loss may occur. Treatment guidelines for NTM lung disease depend upon the type and extent of the infection, and the person's health.
Rat Lungworm (Angiostrongylus cantonensis)
Rat lungworm (Angiostrongylus cantonensis) is a parasite that infects rats. The parasite can infect people if ingested by eating undercooked or raw infected snails or slugs. Though rat lungworm often causes no signs and symptoms, the parasite can cause eosinophlic meningitis in some. Stiff neck, headach, vomiting, nausea, and fever are symptoms of eosinophilic meningitis. Treatment is usually unnecessary. For more severe infections, treatment focuses on alleviating symptoms.
How Serious Is a Blood Clot in the Lungs?
A blood clot is a solid or semisolid clump of blood. When the tissues of our body are injured, excessive blood loss is prevented by the clotting of blood. When a blood clot occurs inside the blood vessels it may lead to serious medical conditions. When a blood clot occurs inside the arteries to the lungs, the condition is called pulmonary embolism (PE).
