Vital capacity is the total amount of air you can expel after maximum inhalation. (orygenvalve.com)

The scores were compared with total and regional lung volumes, and differences in LUS scores between pressure increments were calculated. (bmj.com)
Total numbers and the ratio of FEV1 to FVC are used to assess lung function. (doterra.com)

It is sometimes referred to as a lung diffusion or gas transfer test. (aidsmap.com)

Some may argue that these shifts toward weakness - which include not only our physical strength, but the function of our vital organs and brain - were necessary as our species innovated key technologies. (movnat.com)
Idiopathic inflammatory myopathies often affect extramuscular organs such as the skin, joints, lungs, heart and gastrointestinal tract ( 1 ). (frontiersin.org)

Students create a model that approximates how the lungs, chest and diaphragm interact during breathing. (bioedonline.org)
A chest x-ray taken in January 1980 showed irregular opacities involving the lower halves of both lungs, with bilateral areas of subsegmental atelectasis. (cdc.gov)

They also found that a low forced vital capacity (FVC, a measure of lung capacity) was 5 times more likely among the non-smoking portion of their cohort than expected in the general US population (which includes smokers and non-smokers). (cdc.gov)

Pneumocystis organisms are commonly found in the lungs of healthy individuals. (medscape.com)

Having any of the above exposures does not necessarily mean that you will develop a lung problem. (stanford.edu)
For reasons that are not completely understood, some persons are at increased risk of having a lung reaction to exposures than others. (stanford.edu)
Firefighter exposures during overhaul have the potential to cause changes in spirometric measurements and lung permeability, and self-contained breathing apparatus should be worn during overhaul to prevent lung injury. (cdc.gov)

As you age, your lung capacity gradually decreases, and with it, the average and normal lung capacity changes as well. (orygenvalve.com)
Lower than normal lung vital capacity suggests the person has a respiratory condition. (orygenvalve.com)
In the for normal lung function measures taken from south Sudanese people case of respiratory parameters, predic- for adults and children of both sexes. (who.int)

If obliterative bronchiolitis is suspected, immediate protection from further exposure is crucial to prevent further deterioration of lung function. (cdc.gov)
Lastly, if a patient shows a progressive deterioration in lung function or shows no slowing in this decline, discontinuation of the immunosuppressive medications should be considered. (medscape.com)

[6] Participants also recorded readings from a peak flow meter each morning and night to monitor gradual changes in lung function. (wikibooks.org)

Some of the medications that can cause an inflammatory reaction in the lung include amiodarone, methotrexate, some chemotherapy agents used to treat cancers, and nitrofurantoin (sulfa drugs). (stanford.edu)
Pneumonia is an excess of fluid in the lungs resulting from the inflammatory process. (ukessays.com)
