#MRPearls The bronchial artery circulation is a relatively high pressured system and is responsible for 90% of life threatening hemoptysis cases. (1/7) @VCU_IMRes #Tweetorial
#MRPearls In contrast, the pulmonary artery circulation is a low pressured system with most episodes of non-life threatening hemoptysis occurring from this circulation. (2/7) @mkashiouris
#MRPearls The initial management of massive hemoptysis should include protecting the non-bleeding lung by turning the patient to the bleeding side. Time is lung in this situation. (3/7)
#MRPearls Of note, massive hemoptysis was previously defined as 200-100mL/24h (hotly debated); however, should consider focusing on additional clinical factors such as briskness of bleed, availability of therapeutic options, and physiologic reserve. (4/7)
#MRPearls Tuberculosis, bronchiectasis, mycetoma, and cancer are the leading etiologies of massive hemoptysis. However, check out this awesome table from @accpchest and @samirashojaee listing other etiologies of life-threatening hemoptysis. (5/7)
#MRPearls A standardized algorithm and checklist of tools will improve emergency preparedness and rapid response to bleeding emergencies. Again, @chest and @samirashojaee provide us with an excellent table. (6/7)
#MRPearls For more information regarding massive hemoptysis, check out these resources. (7/7)
