    Yeah realistically it isn’t a big concern. Like you should try not to inject air into people’s veins, but the minimum amount that is likely to cause problems is about 20 cc (which is a lot), but it’s likely to take much more than that to be fatal, usually in excess of 150 cc.

      Damn for real? Growing up id always heard even the tiniest bubbles can put you into shock/death. Made me terrified for a long while growing up… 20cc is a lot of air!

        It’s one of those situations where ~2cc can potentially cause complications and a bubble could theoretically cause problems but is also unlikely, so when you ask a doctor they’ll be like “technically yes, but” and everyone hears “confirmed, bubble=dead”

        Bread’s numbers appear to be for veinous air embolism. A much smaller embolism can kill you in other areas… 2 cc in cerebral, 0.5 cc in the coronary artery.

        Arterial, tiny bubbles cause strokes. Venous, giant bubbles cause air emboli.

        Sometimes there’s connections that shouldn’t be there that can cause venous bubbles to cross over and be a problem.

      cm3 (with markdown ^3^)

      cm³ (with unicode ³, which a bunch of keyboard layouts have on AltGr+3)

      ㎤ (one unicode character)

        You are a gentleman and a scholar. Now how do I figure out how to do this for other similar use cases? Is there a table I can look up?
