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 ]
The most important factor for treating DAD or ARDS is to treat the underlying cause of the injury to the lungs, [9] for example pneumonia or sepsis. These patients will have problems with oxygenation, meaning they will likely need a breathing tube , medications to keep them comfortable (sedative, paralytic, and/or analgesic), and a mechanical ...
Usually spoken sounds of a whispered volume by the patient would not be heard by the clinician auscultating a lung field with a stethoscope. However, in areas of the lung where there is lung consolidation, these whispered spoken sounds by the patient (such as saying 'ninety-nine') will be clearly heard through the stethoscope. This increase in ...
The cause of TRALI is currently not fully understood. 80–85% of cases are thought to be immune mediated. [5] [6] Antibodies directed toward human leukocyte antigens (HLA) or human neutrophil antigens (HNA) have been implicated, with transfused antibodies shown to bind antigens expressed on pulmonary endothelial cells to initiate acute inflammation in the lungs.
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
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.
Rescue death (or reflow syndrome) is a hypothesized fatal condition that can occur after blood pools in a part of the body for a prolonged period such as during suspension trauma. There are several proposed mechanisms for this phenomenon.
Cytotoxic T-cell activity: Fas-induced apoptosis and the perforin pathway are the two main mechanisms by which cytotoxic T lymphocytes induce cell death in cells expressing foreign antigens. [13] Immune privilege: Cells in immune privileged areas such as the cornea or testes express Fas ligand and induce the apoptosis of infiltrating ...
