CYANOSIS : Causes, Symptoms, Types, Treatment I What is cyanosis? Peripheral and Central Cyanosis

Cyanosis: Causes, Symptoms, Types, Treatment | What is cyanosis? Peripheral and Central Cyanosis WELCOME TO DAILY DOSE OF MEDICINE Today we will learn about cyanosis. WHAT IS CYANOSIS? Cyanosis is an unusual bluish cast or discoloration of the skin and mucous membranes, which is commonly noticed around the lips, mouth, palms of the hands, fingernails and soles of the feet. This condition commonly called “blue hands or feet,” signifies hypoxemia, or an abnormally low level of oxygen in the blood. It is also called deoxygenated hemoglobin. TYPES OF CYANOSIS Cyanosis can be divided into Central Cyanosis, Peripheral Cyanosis, Differential Cyanosis, or Cyanosis, amongst new-borns and babies. Symptoms of peripheral cyanosis People with peripheral cyanosis may notice the following symptoms: the skin on the fingertips, toes, palms, or feet is bluey-green the affected body part feels cold to the touch the color returns to normal after warming up the body part Common causes of peripheral cyanosis include: Raynaud’s syndrome. Raynaud’s disease is a condition where the fingertips and toes become painful and become blue or white in cold temperatures. This happens when the blood vessels narrow, preventing blood from reaching the extremities. Low blood pressure. Low blood pressure is when there is not enough pressure to push blood and oxygen to the hands and feet. Low blood pressure is also called hypotension. Hypothermia. This is where the body temperature drops to dangerously low levels. Hypothermia is a medical emergency. Vein or artery problems. If a person has problems with their veins or arteries, their bodies may not send enough blood and oxygen to their hands and feet. Possible causes include venous insufficiency, peripheral vascular disease, or blockages in the veins or arteries. Heart failure. When a person has heart failure, their heart may not be able to pump blood around the body effectively. Problems with the lymph system. Lymphatic dysfunction is a condition where the lymph fluid does not flow and drain as it should. This often results in tissues that swell up with lymph fluid. Deep vein thrombosis. This is caused by clots that form in the veins in the leg or limb extremities. Hypovolemic shock. When a person experiences hypovolemic shock, their body diverts blood from the skin towards the internal organs. Peripheral vs. central cyanosis The key difference between peripheral and central cyanosis is how they affect the body. Peripheral cyanosis affects a person’s hands or legs, especially the extremities, such as fingertips, fingernails, and feet. It may affect just one side of the body or both sides equally. Central cyanosis affects the core organs of the body, causing a blue-green tint across central areas of the body, the lips, or the tongue. The symptoms of central cyanosis do not get better when the body part is heated up. Diagnosis Doctors diagnose peripheral cyanosis through a combination of physical tests, imaging scans, such as X-rays, and blood tests. These tests can identify the presence of other conditions that affect the heart or lungs or that alter the body’s normal oxygen levels. It is vital to follow the doctor’s advice about diagnosing the underlying cause of peripheral cyanosis. When to see a doctor: In most cases, peripheral cyanosis is a symptom of another condition rather than being a medical condition by itself. Some of the underlying conditions could be life-threatening, so anyone experiencing any of the following signs and symptom must seek medical treatment immediately: difficulty breathing or gasping for breath chest pain profuse sweating sudden pain or numbness in the limbs, hands, or feet inability to concentrate or disorientation fever- or flu-like symptoms How do you check for cyanosis? What is the cause of cyanosis? Does cyanosis go away? How long does cyanosis last? OVERVIEW Cyanosis is the medical term for a bluish color of the skin and the mucous membranes due to an insufficient level of oxygen in the blood. For example, the lips and fingernails may show cyanosis. Cyanosis can be evident at birth due to the presence of a heart malformation that permits blood that is not fully oxygenated to enter the arterial circulation. Cyanosis can also appear at any time later in life and often accompanies conditions in which lung function is compromised (resulting in an inability to fully oxygenate the blood) or conditions in which the heart's pumping function is compromised. The presence of abnormal forms of hemoglobin or other abnormalities of the blood cells can also sometimes cause cyanosis. The medical term for lowered oxygen levels is hypoxia; the term anoxia refers to the absence of oxygen. Pseudocyanosis is the appearance of cyanosis that is not associated with reduced oxygen delivery to tissues. Most causes are related to the ingestion of metals (such as silver or lead) or drugs/toxins.
