It’s come up a lot lately, so I want to talk about large-bore IV (LBIV) access for a sec


A big IV can be the difference between life and death for a bleeding or severely volume-down patient


But what's "good enough"?


Here's some of why LBIVs matter
🧵 🔑 Points:

🩸Large bore = 16g or 14g pIV (or a venous sheath).

🩸20g and 18g don’t cut it.
 
🩸Central lines, PICCs, other long catheters don’t cut it either.
 
🩸No claves or connectors!

(1/) I want to bounce around a disease model for #COVID19. This is hypothesis, some parts are hand-wavy, but I'd like to think a lot is also based on evidence. I'll try to clearly distinguish knowns from assumptions as we go...

#COVID2019 #SARSCoV2 #medtwitter #FOAMcc #FOAMed Would love to hear some #ICU/#CriticalCare/#PCCM tweeps thoughts on this idea.
