• Expectoration of blood that originated in the lungs or bronchial tubes
• Differential
• Extrapulmonary: Oral, GI, epistaxis
• Airways: Tracheobronchitis (most common cause), bronchiectasis (esp with CF), foreign body, tracheostomy related
• Pulmonary parenchyma: PNA, cavitary lesions, tumor (often metastatic), trauma, TB
• Pulmonary vasculature: IPH, Heiner syndrome (assoc w/ cow’s milk), vasculitis (Wegener, Goodpasture, HSP, SLE), pulm HTN (arterial or venous), pulm infarction/PE, AVMs, coagulopathies
• Diagnostic studies
• Labs: CBC, ANA, anti-GBM, ANCA, U/A (eval for hematuria), BUN/Cr, PT/PTT, PPD
• pH analysis of sample (hematemesis: ↓ pH vs. hemoptysis: ↑ pH)
• Radiographic studies: CXR (patchy or diffuse alveolar opacities in DAH)
• Consider helical chest CT
• Consider echocardiography to r/o heart disease
• Diagnostic procedures
• Flex bronch/BAL: Hemosiderin-laden macrophages present from 3 d–wk after bleed
• Open lung biopsy
• Management
• Treat underlying cause once identified
• Mild hemoptysis: No immediate treatment required
• Massive hemoptysis: Provide O2, decubitus position (w/ bleeding side down to
promote oxygenation), selective intubation or main stem bronchus on nonbleeding side, bronchial artery embolization, rigid bronchoscopy, surgical resection
