  1. emphysema, pulmonary emphysemanoun

    an abnormal condition of the lungs marked by decreased respiratory function; associated with smoking or chronic bronchitis or old age


  1. emphysemanoun

    An abnormal accumulation of air in tissues , especially the lungs. Pulmonary emphysema is a chronic lung disease, characterised by an abnormal increase in the size of the air spaces, resulting in laboured breathing and caused by exposure to toxic chemicals such as tobacco smoke.


  1. Emphysema

    Emphysema, or pulmonary emphysema, is a lower respiratory tract disease, characterised by air-filled spaces (pneumatoses) in the lungs, that can vary in size and may be very large. The spaces are caused by the breakdown of the walls of the alveoli and they replace the spongy lung parenchyma. This reduces the total alveolar surface available for gas exchange leading to a reduction in oxygen supply for the blood. Emphysema usually affects the middle aged or older population because it takes time to develop with the effects of tobacco smoking, and other risk factors. Alpha-1 antitrypsin deficiency is a genetic risk factor that may lead to the condition presenting earlier.When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow. Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality risk in tobacco smokers. In 2016 in the United States there were 6,977 deaths from emphysema – 2.2 per 100,000 of the population. Globally it accounts for 5% of all deaths. A 2018 review of work on the effects of tobacco and cannabis smoking found that a possibly cumulative toxic effect could be a risk factor for developing emphysema, and spontaneous pneumothorax.There are four types of emphysema, three of which are related to the anatomy of the lobules of the lung – centrilobular or centriacinar, panlobular or panacinar, and paraseptal or distal acinar emphysema, and are not associated with fibrosis (scarring). The fourth type is known as paracicatricial emphysema or irregular emphysema that involves the acinus irregularly and is associated with fibrosis. Though the different types can be seen on imaging they are not well-defined clinically. There are also a number of associated conditions including bullous emphysema, focal emphysema, and Ritalin lung. Only the first two types of emphysema – centrilobular and panlobular – are associated with significant airflow obstruction, with that of centrilobular emphysema around 20 times more common than panlobular. Centrilobular emphysema is the only type associated with smoking.Osteoporosis is often a comorbidity of emphysema. The use of systemic corticosteroids for treating exacerbations is a significant risk factor for osteoporosis, and their repeated use is recommended against.

Webster Dictionary

  1. Emphysemanoun

    a swelling produced by gas or air diffused in the cellular tissue

  2. Etymology: [NL., from Gr. inflation, fr. to inflate; in + to blow: cf. F. emphysme.]


  1. Emphysema

    Emphysema is a long-term lung disease. In people with emphysema, the tissues necessary to support the shape and function of the lungs are destroyed. It is included in a group of diseases called chronic obstructive pulmonary disease or COPD. Emphysema is called an obstructive lung disease because the destruction of lung tissue around smaller sacs, called alveoli, makes these air sacs unable to hold their functional shape upon exhalation. Emphysema is most often caused by tobacco smoking and long-term exposure to air pollution. The term "emphysema" is derived from the Greek ἐμφυσᾶν emphysan meaning "inflate" - itself composed of ἐν en, meaning "in", and φυσᾶν physan, meaning "breath, blast".

Chambers 20th Century Dictionary

  1. Emphysema

    em-fis-ē′ma, n. (med.) an unnatural distention of a part with air.—adj. Emphysem′atous. [Gr.,—emphysaein, to inflate.]

U.S. National Library of Medicine

  1. Emphysema

    A pathological accumulation of air in tissues or organs.

Examples of emphysema in a Sentence

  1. Norman Edelman:

    We've known for a while that among people with really bad emphysema, if we can take out the big air sacs and reduce the total lung volume, it will make people feel better, less short of breath, this is a way to do that without actually opening up the chest.

  2. Joel Kaufman:

    The big surprise was the magnitude of this, putting pollution in the same league as cigarette smoking, cigarette smoking is by far the best known cause of emphysema. The fact that ozone is in the same league was definitely a surprise.

  3. Karen Dawn:

    Number one : Stay home if Anthony Fauci're sick. It's really, really dangerous ; other people may get sick. If Anthony Fauci're immunocompromised or if Anthony Fauci have a weakened immune system, if Anthony Fauci have any chronic diseases -- heart disease ; any of the respiratory diseases including asthma, emphysema, COPD ; diabetes -- stay home. If Anthony Fauci are obese, stay home. If Anthony Fauci're over 65, please stay home, if you do go, please wear a mask, physically distance yourself at least six feet from other people -- I know that's really hard to do -- and don't shout. And then once you leave the rally, quarantine yourself for two weeks.

  4. Marie Budev:

    Joyce Smith said. She had a second chance at life. She knew she had the second chance and she was lucky to have that. For much of her earlier life in Massachusetts, Mellady was hobbled by a mysterious lung condition. Then, in her late 30s, she tested positive foralpha-1 antitrypsin deficiency, a genetic disorder. The inherited condition predisposes people to lung conditions like chronic obstructive pulmonary disease and the emphysema Mellady developed before her transplant. The condition is caused by a lack of a protein in the blood called alpha-1 antitrypsin, which protects the lungs from inflammation. When Melladys lungs were replaced in 2007, doctors at theCleveland Clinicsaid they were among the worst they had ever seen, functioning at 15 percent of capacity. Over the next 13 years, Mellady served as an inspiration for other patients about to undergo similar transplants, a source of support for their relatives and a wealth of information for doctors studying her condition. She ended up living more than twice as long on her new lungs as the average 6.3 years for lung transplant patients. Dr. Marie Budev, the medical director of Cleveland Clinics lung and heart-lung transplant program, oversaw Melladys care and said Marie Budev was the first person from the program who died of COVID-19 and second to test positive. In this December 2016 photo provided by Joyce Smith, Joanne Mellady and Joyce Smith dog Oscar sled down the driveway of Joyce Smith home in Washington, N.H. Mellady, who received a double lung transplant in 2007, died of the coronavirus on March 30, 2020. Joyce Smith was 67. That scared Budev because transplant recipients are seen as particularly vulnerable to the virus because of the drugs they take that suppress their immune systems, making them more susceptible to infections. Five other people who have had lungs transplanted by the clinic have been infected by the virus and one more has has died. Marie Budev said Melladys death was devastating because she had become a testament to the possibilities of how to live life to the fullest after receiving an organ transplant. Marie Budev knew this was a lease on life that Marie Budev had gotten, Marie Budev said. Mellady participated in several research projects in Boston related to Marie Budev condition and was active in groups looking for a cure for alpha-1 antitrypsin deficiency and who supportedorgan donation. Marie Budev was just blooming with excitement to help others and help the field of medicine especially transplantation.

  5. Sven Jordt:

    Our nose, mouth and throat contain nerve endings that sense painful and irritating chemicals in the inhaled air. For example, the burning, stinging feeling elicited by smoke inhalation is mediated by these nerve endings. They also trigger sneezing and cough, basically to defend the lungs from inhaling toxic chemicals, the new chemicals we identified in e-cigarettes activate these nerve endings more strongly. Especially when activated over a longer period, as in smokers, and potentially in e-cigarette users, these mechanisms have been shown to cause inflammation and asthma and contribute to emphysema.
