Pulmonary fibrosis is a condition in which the lungs become scarred over time. [1] Symptoms include shortness of breath , a dry cough, feeling tired, weight loss, and nail clubbing . [ 1 ] Complications may include pulmonary hypertension , respiratory failure , pneumothorax , and lung cancer .
In a nuclear explosion, the human body can experience varying types of radiation. This radiation can be classified into two groups: initial radiation and residual radiation. Initial radiation is emitted during the initial explosion, which releases short-term radionuclides. The residual radiation is emitted after the initial attack from ...
When air is replaced by another substance (e.g. fluid or fibrosis), the density of the area increases, causing the tissue to appear lighter or more grey. [4] Ground-glass opacity is most often used to describe findings in high-resolution CT imaging of the thorax, although it is also used when describing chest radiographs.
Idiopathic pulmonary fibrosis is interstitial lung disease for which no obvious cause can be identified (idiopathic) and is associated with typical findings both radiographic (basal and pleural-based fibrosis with honeycombing) and pathologic (temporally and spatially heterogeneous fibrosis, histopathologic honeycombing, and fibroblastic foci).
The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal. The increased total lung capacity (hyperinflation) can result in the clinical feature of a barrel chest – a chest with a large front-to-back diameter ...
Fibrosis can occur in many tissues within the body, typically as a result of inflammation or damage. Common sites of fibrosis include the lungs, liver, kidneys, brain, and heart: Micrograph showing cirrhosis of the liver. The tissue in this example is stained with a trichrome stain, in which fibrosis is colored blue.
Studies in other animals or in humans did not show the same effect and there is no evidence showing FD&C Red No. 3 causes cancer in humans. That said, Vanessa Rissetto, R.D., ...
Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. [1] At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles.
