Blue Lips or Fingertips
A bluish discoloration of the skin, particularly of the lips, fingertips, and extremities, is sign of cyanosis. Cyanosis occurs when there is poor blood circulation or a lack of oxygen in the blood.
When a person has a heart murmur and is showing signs of cyanosis, it is an indication that the body’s vital organs are not receiving enough blood. This can be a life-threatening medical emergency.
