Study Notes
Hemoptysis Volume and Risk
- Life-threatening hemoptysis is defined as 400 mL blood loss in 24 hours, or 100–150 mL expectorated at once.
- These thresholds are based on the blood volume of the tracheobronchial tree, typically 100–200 mL.
- Patients are more likely to die from asphyxiation (blood blocking airways) rather than exsanguination (severe blood loss).
- Quantifying hemoptysis volume is often challenging for patients; using comparative references like cups (236 mL) can help.
- Fortunately, life-threatening hemoptysis is relatively uncommon, comprising only 5–15% of all hemoptysis cases.
