Hemoptysis is the coughing up of blood or bloody sputum from the lungs or airway. It may be either self-limiting or recurrent. Massive hemoptysis is defined as 200-600 ml of blood coughed up within a period of 24 hours or less. Hemoptysis can range from small quantities of bloody sputum to life-threatening amounts of blood. The patient may or may not have chest pain.
