Compliance Compliance refers to the distensibility of an elastic structure (such as the lung) and is defined as the change in volume of that structure produced by a change in pressure across the structure.

- The vital capacity was defined by Hutchinson 1 as the quantity of air a person is capable of expiring after the deepest possible inspiration. Although many thoracic diseases are known to diminish the vital capacity, in few, if any, is the reduction more striking than in pneumonia.The sudden fall of the vital capacity in pneumonia and the subsequent increase incident to uncomplicated convalescence are sufficiently uniform to be of diagnostic significance.BSTRACT | REFERENCES. The vital capacity was defined by Hutchinson1 as the quantity of air a person is capable of expiring after the deepest possible inspiration. Although many thoracic diseases are known to diminish the vital capacity, in few, if any, is the reduction more striking than in pneumonia.

Definition Few sensations are as frightening as not being able to get enough air. Shortness of breath — known medically as dyspnea — is often described as an intense tightening in the chest, air hunger or a feeling of suffocation. Very strenuous exercise, extreme temperatures, massive obesity and high altitude all can cause shortness of breath in a healthy person. Outside of these examples, shortness of breath is likely a sign of a medical problem.

- Idiopathic pulmonary fibrosis (IPF) is a chronic and ultimately fatal disease characterized by a progressive decline in lung function. The term pulmonary fibrosis means scarring of lung tissue and is the cause of worsening dyspnea (shortness of breath). Fibrosis is usually associated with a poor prognosis.ung tissue from people with IPF shows a characteristic histopathologic pattern known as usual interstitial pneumonia (UIP). UIP is therefore the pathologic counterpart of IPF. The term ' idiopathic ' is used because the cause of pulmonary fibrosis is still unknown.

Overview Pulmonary fibrosis. Overview. Pulmonary fibrosis Pulmonary fibrosis scars and thickens the tissue around and between the air sacs (alveoli) in your lungs, as shown on the right. A normal lung with normal alveoli is shown on the left. Pulmonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly. As pulmonary fibrosis worsens, you become progressively more short of breath.

Diffuse Interstitial Lung Disease Diffuse interstitial lung disease (ILD) is a group of disorders that affect the connective tissue (interstitium) that forms the support structure of the alveoli (air sacs) of the lungs. In a normal lung, the alveoli fill with air during inhalation.

About Spaghnum Moss, Peat Pots and Pellets This wonderful gardening material is also what peat pots and pellets are made of. Peat pots holds seed starting soil, yet is soft enough for the plant roots to grow right through the walls of the pots. At transplanting time, the plant and pot are planted in the garden soil.

- Atelectasis (Definition) Atelectasis (from greek: ἀτελής, incomplete + ἔκτασις, extension) is defined as the collapse or closure of the lung resulting in reduced or absent gas exchange. It may affect part or all of one lung. It is a condition where the alveoli are deflated, as distinct from pulmonary consolidation.

Pulmonary fibrosis Pulmonary fibrosis (literally scarring of the lungs) is a respiratory disease in which scars are formed in the lung tissues, leading to serious breathing problems. Scar formation, the accumulation of excess fibrous connective tissue (the process called fibrosis), leads to thickening of the walls, and causes reduced oxygen supply in the blood.

Symptoms of Lung Disorders Chronic lung conditions such as asthma, COPD, and interstitial lung disease may wax and wane in severity and can worsen quickly and markedly if another problem, such as a lung infection, occurs. Common symptoms of lung disorders include shortness of breath, coughing, noisy breathing, and chest pain. Some people, however, have only mild symptoms or none at all. In these individuals, the disorder may be detected by a physical examination, on a chest x-ray, or by a test to check lung function.

Bradypnea Shortness of breath. Shortness of breath, also known as dyspnea, is a feeling like one cannot breathe well enough. The American Thoracic Society defines it as a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity, and recommends evaluating dyspnea by assessing the intensity of the distinct sensations, the degree of distress involved, and its burden or impact on activities of daily living. Distinct sensations include effort/work, chest tightness, a

- Pulmonary fibrosis (PF) is one of a family of related diseases called interstitial lung diseases that can result in lung scarring. As the lung tissue becomes scarred, it interferes with a person's ability to breathe. In some cases, the cause of pulmonary fibrosis can be found. But most cases of pulmonary fibrosis have no known cause. These cases are called idiopathic pulmonary fibrosis (IPF).

Obstructive lung disease Obstructive lung disease. Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.

- A pulmonary consolidation is a region of (normally compressible) lung tissue that has filled with liquid, a condition marked by induration (swelling or hardening of normally soft tissue) of a normally aerated lung.It is considered a radiologic sign.he liquid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or hemorrhage from a pulmonary artery). It must be present to diagnose pneumonia: the signs of lobar pneumonia are characteristic and clinically referred to as consolidation.

Medical Terminology Ch.7 pulmonary condition characterized by the destruction of the walls of the alveoli, resulting in fewer overexpanded air sacs. Can occur as a result of long-term heavy smoking. Air pollution also worsens this disease. The patient may not be able to breathe except in a sitting or standing position.

Diffusing capacity The diffusion capacity for oxygen is the proportionality factor relating the rate of oxygen uptake into the lung to the oxygen gradient between the capillary blood and the alveoli (per Fick's laws of diffusion).he single-breath diffusing capacity test is the most common way to determine. The test is performed by having the subject blow out all of the air that he/she can, leaving only the residual lung volume of gas.

Pulmonary fibrosis Pulmonary fibrosis is a respiratory disease in which scars are formed in the lung tissues, leading to serious breathing problems. Scar formation, the accumulation of excess fibrous connective tissue, leads to thickening of the walls, and causes reduced oxygen supply in the blood. As a consequence patients suffer from perpetual shortness of breath. In some patients the specific cause of the disease can be diagnosed, but in others the probable cause cannot be determined, a condition called idiopat

Forced Vital Capacity (FVC) Updated June 27, 2016. Forced vital capacity, or FVC, is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. FVC is used to help determine both the presence and severity of lung diseases.

It could mean anything from scar to mass to pneumonia to collapse of a small lung segment. Without the images to review, it is difficult to determine. Likewise, there are both acute and chronic causes of cystic changes.

What is Lung Volume? Lung volume is the percentage of air that lungs can hold at any given period of time. This differs from person to person. The physical differences that accompany lung volume are known as lung volumes.
