It refers to a characteristic boomerang-shaped area of restricted diffusion in the splenium of the corpus callosum due to cytotoxic edema. [1] This sign is associated with various neurological conditions and is considered a non-specific marker of splenial pathology, often reversible depending on the underlying cause. [2] [3]
Medical treatment for restrictive lung disease is normally limited to supportive care since both the intrinsic and extrinsic causes can have irreversible effects on lung compliance. [10] The supportive therapies focus on maximizing pulmonary function and preserving activity tolerance through oxygen therapy, bronchodilators, inhaled beta ...
In addition, gas transport is only diffusion limited in extreme cases, such as for oxygen uptake at very low ambient oxygen or very high pulmonary blood flow. [citation needed] The diffusing capacity does not directly measure the primary cause of hypoxemia, or low blood oxygen, namely mismatch of ventilation to perfusion: [2]
Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that enables the measurement of the restricted diffusion of water in tissue in order to produce neural tract images instead of using this data solely for the purpose of assigning contrast or colors to pixels in a cross-sectional image.
Causes include hypoventilation, impaired alveolar diffusion, and pulmonary shunting. [8] This definition overlaps considerably with that of hypoxic hypoxia. Pulmonary hypoxia is hypoxia from hypoxemia due to abnormal pulmonary function, and occurs when the lungs receive adequately oxygenated gas which does not oxygenate the blood sufficiently.
The health regulator has cleared the drug's use as an add-on treatment for some adults with inadequately controlled chronic obstructive pulmonary disease (COPD), a condition that progressively ...
COPD causes restricted airflow and breathing problems and is also known as 'smoker's lungs' because in Western countries, it primarily affects cigarette smokers. Nucala is a monoclonal antibody ...
A new survey found that 1 in 5 adults “who say they have no personal or family history of heart attack or stroke,” reported “routinely” taking a low-dose aspirin
