It affects the integumentary system by reducing the amount of oxygen in hemoglobin and raising the amount of deoxygenated blood in the blood supply. This may be seen in cases of shock, heart failure, diseases of blood circulation, and exposure to cold temperatures.
There are two types of Cyanosis: Central Cyanosis and Peripheral Cyanosis, which appear in differing ways in adults and newborns.

Following the physical exam, there is a respiratory examination which shows whether or not there is a poor chest expansion as is seen in asthma and chronic bronchitis. The final exam is a cardiovascular exam which shows abnormal heart sounds, such as murmurs, that may signifying heart
