Hemoptysis may be classified into several subtypes based on duration of symptoms, severity and origin of the bleeding. Based on the duration of symptoms, hemoptysis may be classified as either acute or chronic. Hemoptysis may be classified according to severity into 3 groups of mild, moderate, and massive bleeding. Based on the origin of bleeding, hemoptysis may be classified into two groups of pulmonary versus extrapulmonary bleeding.


  • Hemoptysis may be classified into several subtypes based on:[1][2][3]
  • Based on the severity of bleeding, hemoptysis may be classified as mild, moderate, and massive:[4][5][6][7]
Category Amount
Mild bleeding <30 ml blood in 24 hours
Moderate bleeding 30-200 ml blood in 24 hours
Massive bleeding 200-600 ml blood in 24 hours
