Life-threatening hemoptysis: protect the airway and preserve the non-bleeding lung while definitive hemostasis is mobilized

Step 1 · Emergency

Recognize life threat

Airway obstruction, respiratory failure or hemodynamic instability defines severity better than reported volume
Call airway, bronchoscopy and interventional teams early
Correct immediately reversible coagulopathy/anticoagulant effects when appropriate

Step 2 · Treat

Airway first

High-flow oxygen, suction and large-bore access
Position suspected bleeding lung down when side is known
If intubating, use a large ETT suitable for therapeutic bronchoscopy
Protect/isolate the non-bleeding lung when feasible

Step 3 · Assess / decide

Localize + temporize

Bronchoscopy for airway clearance/localization when needed
Cold saline, topical agents or balloon blockade can temporize selected bleeding
CT/angiography when stable enough and diagnostically useful

Step 4 · Escalate / reassess

Definitive control

Bronchial artery embolization is a major definitive pathway
Surgical input for selected refractory/anatomic causes
Treat infection, malignancy, vascular lesion or other underlying cause

Bedside bottom line

The immediate lethal mechanism is often asphyxiation. Airway protection and preserving ventilation of the non-bleeding lung come before precise blood-volume estimation.

Recognize

Life-threatening hemoptysis is bleeding that causes airway obstruction, respiratory failure or hemodynamic instability. Reported blood volume is often unreliable.

Act

Hold/reverse anticoagulants when appropriate, correct severe coagulopathy and thrombocytopenia according to clinical context, and treat the underlying cause. Avoid blind correction of mildly abnormal INR in cirrhosis without considering the full hemostatic picture.

Escalate

Cold saline, topical vasoconstrictors, balloon blockade and other bronchoscopic measures may temporize bleeding while definitive therapy is arranged.
