Overview
Hemoptysis or haemoptysis (see American and British spelling differences) is the expectoration (coughing up) of blood or of blood-stained sputum from a source below the vocal cords such as the bronchi, larynx, trachea, or lungs (e.g. in tuberculosis or other respiratory infections). It is not the same as hematemesis, which refers to vomiting up blood.
Pathophysiology
In most cases of hemoptysis, bleeding comes from the bronchial arteries as opposed to the pulmonary arteries.
Causes
Common Causes
Common causes of hemoptysis include:
- Bronchitis
- Pneumonia
- Lung neoplasm (in smokers, when hemoptysis is persistent)
- Aspergilloma
- Tuberculosis
- Bronchiectasis
- Coccidioidomycosis
- Pulmonary embolism
- Pneumonic plague
- Idiopathic - in 20% cases

Natural Hisotry, Compilcations and Prognosis
Although uncommon, massive hemoptysis may be fatal.
Diagnostic
Laboratory Findings
- Complete blood count (CBC)
- Sputum for acid-fast stain
- Cytology
- Gram stain / culture
- Prothrombin time/partial thromboplastin time (PT / PTT)
- Pulse oximetry
- Urinalysis
- Blood urea nitrogen (BUN)/creatinine)
- Possible immunologic tests
- Arterial blood gases
Electrolyte and Biomarker Studies
Chest X Ray
- Chest X-ray for both major and minor hemoptysis
CT
- Chest CT scan to show focal bleeding
Other Diagnostic Studies
Treatment
- Treat underling etiologies for minor hemoptysis
- Special attention to airway, breathing and circulation
- Administration of supplemental O2
- Stablize hemodynamics
- Cough suppression
- Intubation
Acute Pharmacotherapies
- IV estrogen
Surgery and Device Based Therapy
- Bronchoscopic balloon tamponade
- Arteriography and embolization
- Emergent thoracic surgery
