Diagnosis ?
PA Catheter Induced Pulmonary Hemorrhage
1. Initially position with bleeding lung dependent
2. ETT , oxygenate, suction
3. Lung isolation: DLT, Bronchial Blocker or single-lumen endobronchial tube?
4. Withdraw PA cath 2-3cm, do not inflate
5. Position with isolated bleeding lung non-dependent + PEEP
