The 68-year-old patient was admitted to the hospital medical floor with a diagnosis of chronic bronchitis. His wife asks the nurse why his skin looks blue. How would you explain cyanosis to the patient and his wife?
What will be an ideal response
Cyanosis is a dusky bluish or grayish discoloration of the skin and mucous membranes that occurs with reduced oxygen levels. Without enough oxygen getting to the tissues the skin in Caucasians appears blue due to the color combination of dark maroon blood seen through the yellowish tint of skin. At close inspection of the conjunctiva and palms and soles may also show evidence of cyanosis.
