The cause of hemolytic crises in this disease is unknown (mainly due to intravascular haemolysis). There is rapid and massive destruction of red blood cells resulting in hemoglobinemia (hemoglobin in the blood, but outside the red blood cells), hemoglobinuria (hemoglobin in urine), intense jaundice, anuria (passing less than 50 milliliters of urine in a day), and finally death in the majority ...
Cyanosis is the change of body tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. [1] Cyanosis is apparent usually in the body tissues covered with thin skin , including the mucous membranes , lips, nail beds , and ear lobes. [ 1 ]
Human blood in veins is not actually blue. Blood is red due to the presence of hemoglobin; deoxygenated blood (in veins) has a deep red color, and oxygenated blood (in arteries) has a light cherry-red color. Veins below the skin can appear blue or green due to subsurface scattering of light through the skin, and aspects of human color ...
Color chart for the detection of the amount of methemoglobin in the blood The diagnosis of methemoglobinemia is made with the typical symptoms, a suggestive history, low oxygen saturation on pulse oximetry measurements (SpO2) and these symptoms (cyanosis and hypoxia) failing to improve on oxygen treatment.
Specific types of congenital heart defects that cause blood to pass directly from the right side of the heart to the left side result in cyanosis. [10] In these defects, some of the blood that is pumped to the body has not been oxygenated by the lungs and therefore will appear more blue.
A blood clot that reaches your brain can cause a stroke. Symptoms of a stroke include sudden: Numbness or weakness, often on one side of your body or face. Confusion. Trouble seeing in one or both ...
That means even when your body is at a normal temperature, the brain continues to turn the temperature up and down, causing hot flashes, explains Yves-Richard Dole, M.D., a board-certified ...
The main body tissues that store lead are the blood, soft tissues, and bone; the half-life of lead in these tissues is measured in weeks for blood, months for soft tissues, and years for bone. [30] Lead in the bones, teeth, hair, and nails is bound tightly and not available to other tissues, and is generally thought not to be harmful. [ 180 ]
