What is cyanosis?

Hypoxia and Hypoxemia:

Hypoxia is a condition in which the supply of oxygen in the tissues is insufficient for supporting normal life functions. Hypoxemia is a term that refers to the low levels of oxygen in the blood. Hypoxia or Hypoxemia are characterized by symptoms such as shortness of breath, light-headedness or dizziness, headaches, pain in the chest, confusion, and high blood pressure.

Answer and Explanation:

Cyanosis is an abnormal bluish or purplish discoloration of the skin and mucous membranes. The bluish appearance of skin and mucous membranes occurs due to the insufficient level of oxygen in the blood. Cyanosis can affect skin, lips, fingers, toes, and nails. Cyanosis can develop due to various external environmental factors such as extremely cold temperature or due to certain health problems and diseases such as pneumonia, anemia, cyanide poisoning, suffocation, asthma, and Raynaud's phenomenon (reduced blood supply to fingers or toes).
