  • Expectoration of blood originating from the tracheobronchial tree
  • Source of bleeding:
    • Bronchial arteries (90%), usually causes profuse bleeding
    • Pulmonary arteries (5%), usually causes small amounts of bleeding
    • Nonbronchial arteries (5%) including intercostal arteries, coronary arteries, thoracic, upper, and inferior phrenic arteries
  • Threshold of massive hemoptysis defined has been defined from 100 mL to 1 L/24 hr:
    • >8 mL/kg/day in children
    • Most common definition is >300–600 mL/24 hr
  • Mortality:
    • Massive hemoptysis (>500 mL/24 hr): 38%
    • Trivial to moderate hemoptysis (<500 mL/24 hr): 4.5%
    • Malignancy and coagulopathy increase the risk of mortality


  • Infectious (most common cause):
    • Acute or chronic bronchitis
    • Pneumonia
    • Necrotizing pneumonia or lung abscess (Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae)

    • Anticoagulants
    • Penicillamine, amiodarone, propylthiouracil, bevacizumab
    • Cocaine (“crack”) lung
    • Organic solvents
  • Trauma:
    • Tracheobronchial rupture
    • Pulmonary contusion
  • Iatrogenic:
    • Bronchoscopy/lung biopsy
