A death rattle is noisy breathing that often occurs in someone near death. [1] Accumulation of fluids such as saliva and bronchial secretions in the throat and upper airways is the cause. [ 2 ] Those who are dying may lose their ability to swallow and may have increased production of bronchial secretions, resulting in such an accumulation. [ 3 ]
This increase in sound exists because sound travels faster and thus with lower loss of intensity through liquid or solid ("fluid mass" or "solid mass," respectively, in the lung) versus gaseous (air in the lung) media. Whispered pectoriloquy is a clinical test typically performed during a medical physical examination to evaluate for the ...
Löffler's syndrome is a disease in which eosinophils accumulate in the lung in response to a parasitic infection. The parasite can be Ascaris , Strongyloides stercoralis , or Dirofilaria immitis [ 1 ] which can enter the body through contact with the soil. [ 2 ]
Throughout the dying process, patients will lose the ability to tolerate their secretions, resulting in a sound often disturbing and emotionally distressing to visitors termed the death rattle. [2] However, the death rattle is a separate phenomenon from agonal respirations specifically related to the patient's inability to tolerate their ...
Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
For many short term radiation deaths (3–30 days), the loss of two important types of cells that are constantly being regenerated causes death. The loss of cells forming blood cells ( bone marrow ) and the cells in the digestive system ( microvilli , which form part of the wall of the intestines ) is fatal.
Patients with the syndrome had hearing and vision loss and were found to have higher concentrations of lymphocytes and proteins in their cerebrospinal fluid. Treatment with immunosuppressive drugs like prednisone followed by Azathioprine were found to have significant effects and patients gradually regained lost function, in some cases after ...
Bronchophony may be caused by a solidification of lung tissue around the bronchi – which may indicate lung cancer – or by fluid in the alveoli, which may indicate pneumonia. However, it may also have benign causes, such as wide bronchi. As such, it is usually an indication for further investigation rather than the main basis of a diagnosis.
