How would you recognize cyanotic skin?

Cyanotic skin is characterized by a bluish or purplish discoloration, typically noticeable on the lips, fingertips, and areas around the eyes. This condition occurs due to inadequate oxygenation of the blood, often associated with respiratory or circulatory problems. To recognize cyanosis, observe the skin's color in natural light and look for changes in color, particularly in areas where blood vessels are close to the surface. If cyanosis is present, it may indicate a medical emergency requiring immediate attention.
