Fun fact, small air bubbles won't cause problems. I can't remember how big they have to be. I'm not going to look it up because I don't want to be on a list.

I'm pretty sure using the fediverse already has you on one

NSA, check

MOSSAD, check

FSB, check

No MOSSAD.

Not enough innocent bystander causalities.

Doing Something Awesome, check

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!

[–] [email protected] 10 points 8 months ago* (last edited 8 months ago)

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.

Fun fact - we will intentionally inject (small) bubbles of air into your veins to look for connections between chambers of your heart that shouldn’t be there. It’s called a Bubble Study. https://www.health.harvard.edu/heart-health/what-is-a-bubble-study

[–] [email protected] 2 points 7 months ago

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.

cm^3^ (with markdown ^3^)

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

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?

Cubic centimeter it's a measurement used for medications

learned this when i saw an inch long airbubble in an IV line slowly making its way towards my arm and i panic called a nurse who said that it'd take a lot more air than that to cause a problem, but disconnected the line and squeezed the air bubble out anyway.

[–] [email protected] 5 points 7 months ago

it's a lot. like 50ml plus.
