Pulmonary Embolism Symptoms

8. Cyanosis
Of course, it is not only the brain that suffers from a lack of oxygen due to a pulmonary embolism. All the other tissues of the body also experience oxygen deprivation. The body has a mechanism that kicks in when it is not getting enough oxygen. It sends the blood flow to the areas that most need it, including the brain and other vital organs. Non-vital areas, such as the extremities, therefore receive even less oxygen.
The lack of oxygen can cause cyanosis, which is a bluish discoloration of the skin. You may notice it particularly in the fingers, especially under the nails, and around the lips.
