Abstract

Hemoptysis is the coughing up of blood from the respiratory tract. The blood can come from the nose, mouth, throat, the airway passages leading to the lungs, or the lungs. Hemoptysis refers specifically to blood that comes from the respiratory tract. Often when a person spits up blood, however, it has come from somewhere else the nose, the back of the throat, or part of the gastrointestinal tract. When blood originates outside of the respiratory tract, the spitting is commonly known as \"pseudohemoptysis\". Vomiting up blood, hematemesis is one type of pseudohemoptysis. Differentiating between hemoptysis and hematemesis is an integral part of diagnosis. Since they involve different parts of the body, the prognoses (the prospect of recovery) and treatments are entirely different. Classifying hemoptysis as mild or massive (some classify it as trivial, moderate, or massive) is somewhat arbitrary, since it is difficult to accurately quantify the amount of blood that a person spits up. It is required to differentiate the life-threatening, \"massive\" hemoptysis requiring immediate medical attention from less severe cases.
