Hi, I’ve never laughed as hard in my life as I did at the idea that you could kill someone by blowing air at them if they have the tiniest of cuts. That’s not how cuts or air work.
Do I even need to debunk that? Have you ever had a cut before? Did you die? Your cut was surrounded by air the entire time. Congratulations, myth busted.
Don’t shoot very high-pressure air at people, especially not inside people, because if the stars align and the air is under enough pressure then the force of the air can hurt them (think like how you can injure someone with a water cannon but not a tap).
But air going into your veins in most circumstances is not actually much of a risk… especially not via a tiny cut. The germs in the air is why your cuts close themselves up as fast as they can, not the air itself.
“However, according to Dr. Barry Wolcott MD, FACP, senior vice president of clinical affairs for WebMD Health, “In general, the small amount of air that can be introduced by a typical syringe is not large enough to cause a fatal air embolism (an air embolism is similar to a blood clot).”“
“Dr. Wolcott explained, “the large amounts of air that can quickly enter through a large plastic catheter which is open to the air — like those placed in the neck or under the collarbone during resuscitations in hospitals and at accident scenes — can be fatal, especially if the patient inhales forcefully while the catheter is open to the air.”“

A large amount of air quickly entering your blood stream, and not being broken up by you, can cause trouble in the same sort of way that a blood clot can… but a teeny tiny air bubble in your saline drip (as a nurse explained to me once when I was on one in hospital) is harmless.
As for blowing air into the vagina… if I was to say the percentage chance that it would happen, I’d actually discover tumblr’s character limit putting so many 0s after the decimal point.
"The Postgrad Medical Journal also reported in 1998 that a UK Department of Health enquiry had found three cases of death by embolism during sexual intercourse and one case of death by embolism during oral sex.”
“That said, it’s a very small risk, and not something that’s going to happen with a light blow to the vulva or vigorous sex session.”
“We got in contact with a number of gynaecologists in the UK and not one was able to speak on the issue since they’d had no personal experience of it. So it really is something of an anomaly.”

We’re talking about four cases and something no gynaecologist has ever even seen.
Oh, and the reason it’s occasionally briefly mentioned in pregnancy books?
“If your guy forms a seal around your vagina with his lips and forces air inside without allowing it to escape,” […] “For one thing, blowing air into the vagina is dangerous only when your below-the-belt blood vessels are engorged due to hormonal changes that occur during menstruation or pregnancy. Plus, your guy would have to be puffing darn hard to put you at risk.”

A dude would have to seal off your vagina so the air didn’t escape, blow exceptionally hard, you’d have to be pregnant or menstruating, Mercury would have to be in retrograde, and eight different gods would have to sign your death warrant. Since I don’t know of many guys who like to seal up a bleeding vagina with their lips, I’m guessing that “it will never happen” is why it’s not in everyday sex ed - not just because the risk is slimmer than my goal weight, but also because no dude is going to do that. Also they probably don’t want to fearmonger… unlike tumblr.
I guess it gets a brief mention in pregnancy stuff since the placenta and blood vessels both make you a little more at risk… and by a little I mean that maybe my list of 0s would now end just before tumblr’s character limit.
