🩸 Hemoptysis Grading & Management
This tool grades hemoptysis severity, recognizes massive hemoptysis, and frames the emergency management pathway.
Death in massive hemoptysis is mostly from asphyxiation rather than exsanguination, so airway protection and positioning take priority over volume replacement. (original synthesis · not guideline verbatim)

When to use
Use to triage from conservative workup for small-volume bleeding to the airway-first resuscitation and embolization pathway for massive hemoptysis.
How it works
Small-volume → conservative workup. Moderate → admit, monitor, localize. Massive (> 300–600 mL/24 h or respiratory failure/instability) → airway first, bleeding-side-down positioning, coagulation correction, CTA/bronchoscopy, bronchial artery embolization (first-line) or surgery.
Key points
- Death in massive hemoptysis is mostly from asphyxiation rather than exsanguination, so airway protection and positioning take priority over volume replacement. (original synthesis · not guideline verbatim)
- Bronchial artery embolization is the first-line definitive treatment, with surgery reserved for focal disease where it fails.
- An upper-GI or upper-airway source is excluded before attributing bleeding to the lungs.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Severity | Small volume (blood streaks/blood-tinged sputum, < 100 mL/24 h, no respiratory/circulatory involvement) |
|---|
→HemoptysisSmall-volume hemoptysis
- Management：Outpatient/ward evaluation, mostly conservative; find the cause (chest X-ray/CT, sputum tests, coagulation); treat the underlying disease (infection/bronchiectasis/tumor, etc.)
- Note：Exclude upper GI bleeding and an upper-airway source; assess bleeding risk in those on anticoagulants/antiplatelets
- Basis：Massive hemoptysis resuscitation and bronchial artery embolization literature (threshold definitions vary slightly between sources)
| Severity | Massive hemoptysis (> 300–600 mL/24 h, or with respiratory failure/hemodynamic instability/asphyxiation signs) |
|---|
→HemoptysisMassive hemoptysis (emergency)
- (1) Airway first：Protect the airway: intubate if needed (a large-bore tube aids suction/bronchoscopy); selective intubation of the healthy side or a bronchial blocker can isolate the bleeding lung to prevent asphyxiation
- (2) Positioning：Lateral decubitus with the bleeding side down to protect the healthy lung; thorough suction
- (3) Resuscitation & coagulation：Fluid/blood-product resuscitation, correct coagulation, stop anticoagulants/antiplatelets; tranexamic acid (TXA) may be used
