Respiratory Failure – Acute/Chronic – Symptoms and Treatment

Definition of Respiratory Failure The inability of the lungs to diffuse enough oxygen into the bloodstream to meet the body’s needs. Respiratory failure may arise from end-stage pulmonary disease, extensive trauma, severe cardiovascular disease (cvd) or crisis (such as heart attack), neurologic damage or injury (such as spinal cord injury, traumatic brain injury [tbi], stroke, or neurodegenerative disorder), or severe infection (sepsis). Respiratory failure […]

Asbestosis – Definition, Symptoms and Treatment

Definition of Asbestosis Asbestosis is damage to the lungs resulting from inhalation of asbestos fibers. During the first half of the 20th century asbestos, a natural substance mined from underground, became common in insulating materials because of its natural heat resistance. In the 1950s researchers linked chronic asbestos inhalation with pulmonary fibrosis and a rare form of lung cancer, mesothelioma, found […]

Hyperventilation Syndrome – Definition, Treatment, Symptoms

Definition and Symptoms of Hyperventilation Syndrome Hyperventilation syndrome is rapid, shallow breathing that causes carbon dioxide levels in the blood to drop below normal. As the balance between carbon dioxide and other gases in the blood is essential for normal pulmonary and cardiovascular function, the decrease triggers actions in the body designed to slow the breathing. Key among these is […]

Silicosis of The Lung – Symptoms and Treatment

Definition of Silicosis of The Lung Silicosis is an obstructive condition of the lungs that develops with repeated and usually long-term exposure to crystalline silica (silica dust). It is a disease of occupational exposure. The silica dust causes irritation and inflammation of the airways and lung tissue. Scar tissue forms when the inflammation heals, resulting in fibrosis that gradually overtakes healthy […]

Aspergillosis – Definition, Symptoms and Treatment

Definition of Aspergillosis Aspergillosis is an opportunistic fungal (yeast) infection that can manifest as pneumonia in people who have hiv/aids, are undergoing chemotherapy to treat cancer, receive immunosuppressive therapy after organ transplantation, or are otherwise immunocompromised. Aspergillosis may also occur as an allergic reaction (called allergic bronchopulmonary aspergillosis or ABPA) in people who have asthma or cystic fibrosis, causing airway inflammation and fluid accumulation in the lungs. Aspergillus, the infective fungus, is common in […]

Hypoxia Definition and Symptoms

Definition of Hypoxia Hypoxiais inadequate oxygen perfusion of the tissues. Hypoxia occurs when the blood cannot deliver adequate oxygen, which may result from pulmonary dysfunction, cardiovascular dysfunction, stroke, traumatic brain injury (tbi), disorders of the blood such as anemia that affect erythrocytes (red blood cells) or hemoglobin, and breathing disturbances such as apnea. It may involve only a defined organ or area, such as […]

Smoking and Pulmonary Disease

Pulmonary Disease and Smoking – Introduction Cigarette smoking is the leading cause of health conditions affecting the LUNGS and accounts for 90 percent of LUNG CANCER in the United States. It is also the leading cause of many forms of CARDIOVASCULAR DISEASE (CVD), including HYPERTENSION, ATHEROSCLEROSIS, ISCHEMIC HEART DISEASE (IHD), CORONARY ARTERY DISEASE (CAD), and PERIPHERAL VASCULAR DISEASE (PVD). Though the correlation between cigarette […]

Asphyxia Definition and Information

Definition of Asphyxia The inability of the lungs to take in air or conduct the oxygen-carbon dioxide exchange, depriving the body of oxygen. Asphyxia is a life-threatening emergency that requires immediate medical treatment. The emergency may occur as a consequence of water or other fluids in the lungs (drowning) that results in suffocation (inability of air to enter the […]

Interstitial Lung Disease – Symptoms and Treatment

Definition of Interstitial Lung Disease Interstitial Lung Disease is a broad term for chronic conditions that restrict the ability of the lungs to function properly, encompassing more than 150 diseases. Interstitial lung disorders, also called interstitial lung disease as a collective term, are typically obstructive, fibrotic (involve SCAR formation), and progressive. Many arise from occupational exposures such as […]

Tachypnea Definition

Definition of Tachypnea Tachypnea is an abnormally rapid respiration rate. Breathing is also usually shallow. The normal respiration rate for healthy adults is 15 to 20 respiratory cycles per minute. In tachypnea the respiration rate can be two to four times normal. Breathing may appear labored, and when the body is not able to meet its needs the person […]
