Peripheral cyanosis is the blue tint in fingers or extremities, due to an inadequate or obstructed circulation. [5] 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 .
The normal peripheral pulses rule out peripheral arterial occlusive disease, where arterial narrowing limits blood flow to the extremities. Pulse oximetry will show a normal oxygen saturation . Unlike the closely related Raynaud's phenomenon , cyanosis is continually persistent.
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]
Someone with mitral stenosis may present with rosy cheeks, whilst the rest of the face has a bluish tinge due to cyanosis. This is especially so in severe mitral stenosis. Because low cardiac output in mitral stenosis produces vasoconstriction, peripheral cyanosis is often seen in the lips, the tip of nose, and the cheeks.
Cyanosis of the hand in an elderly person with low oxygen saturation: Specialty: Pulmonology, toxicology: Symptoms: Cyanosis, numbness or pins and needles feeling of the extremities: Complications: Gangrene, necrosis: Risk factors: Diabetes, coronary artery disease, heart attack, stroke, embolism, thrombosis, deep-vein thrombosis, tobacco smoking
Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
Cyanosis, a bluish tinge of the extremities (peripheral cyanosis), or of tongue (central cyanosis) [4] Pursed-lip breathing [5] Accessory muscle use, including the scalene and intercostal muscles [5] Diaphragmatic breathing, paradoxical movement of the diaphragm outwards during inspiration; Intercostal indrawing
Peripheral cyanosis (eg. bluish color on mucosal membranes or fingers and/or toes) Tachypnea (faster breathing rate) [6] Pale conjunctiva [6] People with respiratory failure often exhibit other signs or symptoms that are associated with the underlying cause of their respiratory failure.
