Massive haemoptysis DDx

Haemoptysis is the symptom of coughing up blood. Massive haemoptysis has no generally accepted definition. Suggested volumes range from 100 mL to more than 1000 mL. A more relevant definition of massive haemoptysis is the volume that is life threatening by virtue of airway obstruction or blood loss (anatomical dead space is only 100-200 mL)
