Massive Hemoptysis — Management Pathway

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Is the airway threatened?
   Massive hemoptysis — is the airway threatened / hemodynamically stable? (Definitions of massive hemoptysis vary (often >100–600 mL/24 h, or any hemoptysis threatening the airway/ventilation); death is usually from asphyxiation rather than blood loss. Causes: bronchiectasis, tuberculosis, tumor, fungal, vascular, coagulopathy, etc. Involve respiratory/interventional radiology/thoracic surgery early.)
   • Airway-threatening / large-volume / unstable → Airway-threatening → airway first + BAE
   • Small–moderate, stable → Small–moderate · stable
2. [End] Small–moderate · stable
   Stable airway: oxygen, cough suppression, affected-side-down positioning (bleeding lung down) to protect the healthy lung; correct coagulopathy, nebulized/IV tranexamic acid if needed; CT/CTA to localize + bronchoscopy; monitor and escalate if bleeding worsens. Find and treat the cause.
3. [End] Airway-threatening → airway first + BAE
   1) Airway first — large-bore endotracheal intubation (≥8 mm to allow suction/bronchoscopy), thorough suction; affected-side-down positioning (bleeding lung down) to protect the healthy lung, with selective intubation of the healthy main bronchus or a bronchial blocker if needed. 2) Resuscitate, correct coagulopathy, IV/nebulized tranexamic acid. 3) Once stable, CT/CTA + bronchoscopy to localize. 4) Definitive hemostasis = bronchial artery embolization (BAE, mainstay) ± bronchoscopy (blocker/local) ± surgical resection. Involve interventional radiology/thoracic surgery early.
