Furthermore, mongolian spots, large birthmarks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. [ 2 ] [ 3 ] Appropriate physical examination and history taking is a crucial part to diagnose cyanosis.
The diagnosis is often suspected based on symptoms and a low blood oxygen that does not improve with oxygen therapy. [3] Diagnosis is confirmed by a blood gas. [3] Treatment is generally with oxygen therapy and methylene blue. [3] Other treatments may include vitamin C, exchange transfusion, and hyperbaric oxygen therapy. [3]
[6] [2] Specifically, it is used to treat methemoglobin levels that are greater than 30% or in which there are symptoms despite oxygen therapy. [2] It has previously been used for treating cyanide poisoning and urinary tract infections, but this use is no longer recommended. [6] Methylene blue is typically given by injection into a vein. [6]
The nail deformity often occurs in people suffering from heart and lung diseases that reduce the amount of oxygen in the blood. It can be a warning sign of a serious problem, doctors say.
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]
Nail clubbing - nails that curve down around the fingertips with nailbeds that bulge is associated with oxygen deprivation and lung, heart, or liver disease. Koilonychia - spooning, or nails that grow upwards. Associated with iron-deficiency anaemia or vitamin B 12 deficiency. [citation needed] Pitting of the nails is associated with psoriasis.
Hypoxemic hypoxia is a lack of oxygen caused by low oxygen tension in the arterial blood, due to the inability of the lungs to sufficiently oxygenate the blood. Causes include hypoventilation, impaired alveolar diffusion, and pulmonary shunting. [8] This definition overlaps considerably with that of hypoxic hypoxia.
A more recent treatment for severe Raynaud's is the use of botulinum toxin. The 2009 article [ 37 ] studied 19 patients ranging in age from 15 to 72 years with severe Raynaud's phenomenon of which 16 patients (84%) reported pain reduction at rest; 13 patients reported immediate pain relief, three more had gradual pain reduction over 1–2 months.
