Flashcards

Life-threatening hemoptysis

A serious condition in which a significant amount of blood is coughed up from the lungs, potentially leading to death.

Tracheobronchial tree blood volume

The amount of blood normally present in the airways of the lungs.

Using cups as a reference for blood loss

A method to estimate blood volume lost by a patient when they cannot quantify it in mL.

Asphyxiation as a primary risk in life-threatening hemoptysis

The immediate danger for patients with life-threatening hemoptysis is not blood loss itself, but rather suffocation from blood filling the airways.

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.
