ABC's of nose bleeds: Nosebleeds usually occur on the septum at a point where superficial blood vessels come together. This area is very accessible and can be compressed by simply squeezing on both sides, just below the bony pyramid of the nose. Tilt the head back to elevate the nose and keep compression for approximately 3-5 minutes. If continued bleeding hold for 5 more. Seek medical attention soon!
