OVERVIEW:

Definition:

expectoration/ coughing of blood originating from tracheobronchial tree


Sources:

Bronchial arteries (90%): under systemic circulatory pressure to supply supporting structures of the lung → heavier bleeding
Pulmonary arteries (5%): under low pressure to supply alveoli → milder bleeding
Nonbronchial arteries (5%): intercostal arteries, coronary arteries, thoracic/ upper/ inferior phrenic arteries


Quantification:

Mild: <20mL/ 24h
Massive defined anywhere from >300mL-1L/ 24hr
Mortality: 38% for massive (>500mL/ 24hr) vs 4.5% for nonmassive




Etiology (in adults):
