The origin of blood can be identified by observing its color. Bright-red, foamy blood comes from the respiratory tract, whereas dark-red, coffee-colored blood comes from the gastrointestinal tract. Sometimes hemoptysis may be rust-colored. [citation needed] Lung cancer, including both non-small cell lung carcinoma and small cell lung carcinoma ...
Blood cultures should be performed in patients with symptoms, signs, or laboratory abnormalities compatible with mycobacterium infection. Blood cultures are not routinely recommended for asymptomatic persons, even for those who have CD4+ T-lymphocyte counts less than 100 cells/uL. [14]
Eosinophilic bronchitis is also defined by the increased number of eosinophils, a type of white blood cell, in the sputum compared to that of healthy people. [2] As patients with asthma usually present with eosinophils in the sputum as well, some literature distinguish the two by classifying the condition as non-asthmatic eosinophilic ...
Blood-streaked sputum –an indicator of possible inflammation of the throat (larynx and/or trachea) or bronchi; lung cancer; other bleeding erosions, ulcers, or tumors of the lower airway. Pink sputum – it indicates sputum evenly mixed with blood from alveoli and/or small peripheral bronchi as is seen in potential pulmonary edema.
The primary site of infection in the lungs, known as the Ghon focus, is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. [13] Tuberculosis of the lungs may also occur via infection from the blood stream. This is known as a Simon focus and is typically found in the top of the lung. [91]
Primarily white blood cells, mainly mononuclear cells, generate the inflammation. [60] As well as damaging the lungs, many viruses simultaneously affect other organs and thus disrupt other body functions. Viruses also make the body more susceptible to bacterial infections; in this way, bacterial pneumonia can occur at the same time as viral ...
Acute posthemorrhagic anemia (also known as acute blood loss anemia) is a condition in which a person quickly loses a large volume of circulating hemoglobin. Acute blood loss is usually associated with an incident of trauma or a severe injury resulting in a large loss of blood. It can also occur during or after a surgical procedure. [19]
[citation needed] An abrupt worsening in COPD symptoms may cause rupture of the airways in the lungs, which in turn may cause a spontaneous pneumothorax. [4] In infection, there is often weakness, fever and chills. If due to a bacterial infection, the sputum may be slightly streaked with blood and coloured yellow or green. [5]
