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 ]
Vivien Theodore Thomas (August 29, 1910 [1] – November 26, 1985) [2] was an American laboratory supervisor who, in the 1940s, played a major role in developing a procedure now called the Blalock–Thomas–Taussig shunt used to treat blue baby syndrome (now known as cyanotic heart disease) along with surgeon Alfred Blalock and cardiologist Helen B. Taussig. [3]
Blue baby syndrome can refer to conditions that cause cyanosis, or blueness of the skin, in babies as a result of low oxygen levels in the blood. This term has traditionally been applied to cyanosis as a result of:. [1] Cyanotic heart disease, which is a category of congenital heart defect that results in low levels of oxygen in the blood. [2]
These are acute hypoxia spells, characterized by shortness of breath, cyanosis, agitation, and loss of consciousness. [ 20 ] : 200 This may be initiated by any event – such as anxiety, pain, dehydration, or fever [ 20 ] – leading to decreased oxygen saturation or that causes decreased systemic vascular resistance, which in turn leads to ...
This characteristic blue-violet cyanosis in expiring patients led to the name 'purple death'. [ 24 ] [ 25 ] [ 26 ] The Aldershot physicians later wrote in The Lancet , "the influenza pneumococcal purulent bronchitis we and others described in 1916 and 1917 is fundamentally the same condition as the influenza of this present pandemic."
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [1]
Methemoglobinemia, or methaemoglobinaemia, is a condition of elevated methemoglobin in the blood. [2] Symptoms may include headache, dizziness, shortness of breath, nausea, poor muscle coordination, and blue-colored skin (cyanosis). [2]
Symptoms include a blueish or greenish coloration of the blood (cyanosis), skin, and mucous membranes, even though a blood count test may not show any abnormalities in the blood. This discoloration is caused by greater than 5 grams per cent of deoxyhemoglobin, or 1.5 grams per cent of methemoglobin, or 0.5 grams per cent of sulfhemoglobin, all ...
