Haemoptysis

Haemoptysis is the coughing of blood originating from the respiratory tract below the level of the larynx. Haemoptysis should be differentiated from:

Haematemesis - vomiting of blood from the gastrointestinal (GI) tract.
Pseudohaemoptysis - where a cough reflex is stimulated by blood not derived from the lungs or bronchial tubes. This may be from the oral cavity or nasopharynx (eg, following an epistaxis) or following aspiration of haematemesis into the lungs.
