Nose Bleeding

Causes of Nose Bleeding most commonly are, trauma to the nose. Trauma to the outside of the nose, such as a blow to the face, or trauma inside the nose, such as nose picking or repeated irritation from a cold, can cause a nosebleed.
Less commonly, an underlying disease process, such as an inability of the blood to clot, may contribute to the bleeding. Abnormal blood vessels or cancers in the nose are rare causes of nosebleeds. High blood pressure may also contribute to bleeding but is almost never the only reason for a nosebleed.

Blood Transfusion

A blood transfusion is the transfer of blood or blood products from one person (donor) into another person's bloodstream (recipient). This is usually done as a lifesaving maneuver to replace blood cells or blood products lost through severe bleeding, during surgery when blood loss occurs or to increase the blood count in an anemic patient.

Blood transfusions can be a life saving measure. Volunteer donor blood usually is readily available, and when properly tested has a low incidence of adverse events. The likelihood of contracting infections from a blood transfusion is very low. Blood conserving techniques are an important aspect of limiting transfusion requirements. Blood banks are responsible for collecting, testing and storing blood. People with Type O, negative blood are considered universal donors as it is safe to transfuse to nearly everyone.
