  Cyanosis is characterized by bluish discoloration of skin and mucous membranes. Cyanosis is usually a sign of an underlying condition rather than being a disease in itself. […] The most common symptoms of the condition are bluish discoloration of the lips, fingers, and toes. […] This is manifested by bluish or purple discoloration of tongue and lips and mucous membranes of the mouth. […] It is seen in diseases of the heart or lungs and in abnormal haemoglobin conditions like methemoglobin and sulfhemoglobin etc. […] Here cyanosis is caused due to desaturation of central arterial blood due to diseases of the heart and lungs. […] This deoxygenated venous blood instead of going to the lungs for oxygenation moves to the general blood circulation of the body leading to symptoms of cyanosis.

• #4 Cyanosis – Wikipedia

  https://en.wikipedia.org/wiki/Cyanosis

  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. Cyanosis is apparent usually in the body tissues covered with thin skin, including the mucous membranes, lips, nail beds, and ear lobes. […] Central cyanosis occurs due to decrease in arterial oxygen saturation (SaO2), and begins to show once the concentration of deoxyhemoglobin in the blood reaches a concentration of 5.0 g/dL ( 3.1 mmol/L or oxygen saturation of 85%). This indicates a cardiopulmonary condition. […] Peripheral cyanosis happens when there is increased concentration of deoxyhemoglobin on the venous side of the peripheral circulation. In other words, cyanosis is dependent on the concentration of deoxyhemoglobin.

• #5 Cyanosis – Clinical Methods – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK367/

  Cyanosis is a bluish color of mucous membranes and/or skin. While this is most frequently attributable to increased amounts of unoxygenated hemoglobin (deoxyhemoglobin) in the vasculature, there are other causes of bluish skin color. […] According to Lundsgaard and Van Slyke (1923), as well as subsequent investigators, cyanosis generally becomes apparent when the subpapillary capillaries contain from 4 to 6 gm/dl of deoxyhemoglobin. […] The usual pattern of cyanosis noted in conditions of reduced blood flow is for peripheral sites, in particular the extremities, to be affected preferentially (acrocyanosis). Central portions of the body are typically spared. […] More than 20 hemoglobins with low oxygen affinities have been described. With most of them there are few clinical manifestations apart from cyanosis.

• #6 Blue Lips (Cyanosis): Causes and Treatment

  https://www.verywellhealth.com/blue-lips-5082283

  There are two types of cyanosis that typically cause blue lips: central and peripheral. However, blue lips are more likely to occur with the central type than the peripheral type. […] A bluish discoloration of a lot of your skin as well as your lips is called central cyanosis. It is usually a sign of a medical condition that is preventing your body from getting enough oxygen that needs to be treated right away. […] In general, blue lips and other cyanotic changes happen because of a medical problem. […] Heart disease is a major potential cause that must be checked for. In a newborn, blue lips can be a sign of a heart problem they were born with (congenital) that may need a surgical repair. […] In an adult, blue lips can be a sign of heart failure, a heart valve problem, or another type of heart condition.

• #7 Cyanosis | Symptoms, Diagnosis & Treatment

  https://www.cincinnatichildrens.org/health/c/cyanosis

  Cyanosis refers to a bluish-purple color of the skin. It is most easily seen where the skin is thin, such as the lips, mouth, earlobes and fingernails. […] Cyanosis means there may be decreased oxygen in the bloodstream. It may suggest a problem with the lungs or heart. Cyanosis is a finding based on what is seen, not by a laboratory test. […] Central cyanosis refers to cyanosis found on central parts of the body, including the mouth, head and torso. Central cyanosis is never normal in the newborn period and is almost always linked to a lower amount of oxygen in the blood. It could be due to a problem of the heart, lungs or blood. […] Cyanosis in congenital heart defects results when blue blood (oxygen poor) does not reach the lungs to make red blood, or when red blood (oxygen rich) is mixed with blue blood before it returns to the body. […] Cyanosis on the lips, tongue, head or torso is central cyanosis, and should be promptly evaluated by a doctor.

• #8 Cyanosis – Wikipedia

  https://en.wikipedia.org/wiki/Cyanosis

  Central cyanosis is often due to a circulatory or ventilatory problem that leads to poor blood oxygenation in the lungs. It develops when arterial oxygen saturation drops below 85% or 75%. […] Peripheral cyanosis is the blue tint in fingers or extremities, due to an inadequate or obstructed circulation. The blood reaching the extremities is not oxygen-rich and when viewed through the skin a combination of factors can lead to the appearance of a blue color. […] Signs of severe anemia may include pale mucosa (lips, eyelids, and gums), fatigue, lightheadedness, and irregular heartbeats.

  https://passport.world.rugby/player-welfare-medical/world-rugby-first-aid-in-rugby/chapter-6-breathing-assessment-and-chest-injuries/pallor-andor-cyanosis/

  The red pigment in blood is known as haemoglobin and is responsible for binding to oxygen and carrying it around the body. […] Haemoglobin without oxygen turns pale or grey/blue. If breathing is inefficient and sufficient oxygen cannot get through the lungs to bind to haemoglobin, then the lips and tongue may appear pale or grey/blue. This grey/blue discolouration is called cyanosis. […] Central cyanosis is always significant and should be looked for during an assessment of breathing. If you see central cyanosis, the casualty is not able to get enough oxygen into the body and you need help urgently. Lack of oxygen is known as hypoxia and hypoxic people can die.

• #12 Central and Peripheral Cyanosis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK559167/

  Peripheral cyanosis occurs due to the inability of the body to deliver oxygen-rich blood to the peripheral tissues. Congestive peripheral cyanosis can be caused due to the slowing of blood flow. Ischemic peripheral cyanosis occurs when vasoconstriction leads to diminished peripheral blood flow. In peripheral cyanosis, there is normal arterial oxygen saturation but increased oxygen extraction by the peripheral tissue in the capillary bed in the setting of peripheral vasoconstriction and decreased peripheral blood flow. This results in a significant difference in the saturation between the arterial and venous blood, with increased deoxygenated blood on the venous side of the capillary beds. […] The goal of managing peripheral cyanosis is to identify and treat the underlying cause of vasoconstriction and the limited supply of oxygen-rich blood to the extremities. Peripheral cyanosis is usually reversible, restoring oxygenated blood flow to the extremities. It can rarely pose a life-threatening emergency. However, timely management is important to improve outcomes and prevent complications.

  Peripheral cyanosis occurs due to the inability of the body to deliver oxygen-rich blood to the peripheral tissues. Congestive peripheral cyanosis can be caused due to the slowing of blood flow. Ischemic peripheral cyanosis occurs when vasoconstriction leads to diminished peripheral blood flow. In peripheral cyanosis, there is normal arterial oxygen saturation but increased oxygen extraction by the peripheral tissue in the capillary bed in the setting of peripheral vasoconstriction and decreased peripheral blood flow. This results in a significant difference in the saturation between the arterial and venous blood, with increased deoxygenated blood on the venous side of the capillary beds. […] The goal of managing peripheral cyanosis is to identify and treat the underlying cause of vasoconstriction and the limited supply of oxygen-rich blood to the extremities. Peripheral cyanosis is usually reversible, restoring oxygenated blood flow to the extremities. It can rarely pose a life-threatening emergency. However, timely management is important to improve outcomes and prevent complications.

• #81 Central and Peripheral Cyanosis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK559167/

  Peripheral cyanosis occurs due to the inability of the body to deliver oxygen-rich blood to the peripheral tissues. Congestive peripheral cyanosis can be caused due to the slowing of blood flow. Ischemic peripheral cyanosis occurs when vasoconstriction leads to diminished peripheral blood flow. In peripheral cyanosis, there is normal arterial oxygen saturation but increased oxygen extraction by the peripheral tissue in the capillary bed in the setting of peripheral vasoconstriction and decreased peripheral blood flow. This results in a significant difference in the saturation between the arterial and venous blood, with increased deoxygenated blood on the venous side of the capillary beds. […] The goal of managing peripheral cyanosis is to identify and treat the underlying cause of vasoconstriction and the limited supply of oxygen-rich blood to the extremities. Peripheral cyanosis is usually reversible, restoring oxygenated blood flow to the extremities. It can rarely pose a life-threatening emergency. However, timely management is important to improve outcomes and prevent complications.
