Current Events > I don't get how CPR works. You're exhaling CO2 when human lungs need oxygen?

(+) Yeah! (+)

Does the other person's lungs just take any kind of air? If you're exhaling CO2 when the other person needs O2, how does that explain the other person getting oxygen when they're unable to breathe?

I thought it was to kickstart all of that up again but I'm an idiot so idk

Isn't it just filling the lungs up ao the body naturally wants to exhale it and start functioning again?

Your lungs ain't that efficient

---

No, your body isn't able to use most of the oxygen you inhale.

I thought I had him this time. I thought, this one time, Im going to see that @Complete_Idi0t made the topic before rushing in. Ugh.

It has nothing to do with oxygen or CO2, it's just the air being pushed in to expand the lungs to try and get them functioning again. It's like using a defibrillator on the heart.

@Complete_Idi0t

You are exhaling fresh breath that is still saturated with accessible oxygen.

The saving grace is you tonguing the person down and even though they're unconscious their penis and/or vagina aren't so they're like "wake up fam we about to get some"

this is wrong, you exhale about 16% oxygen in mouth to mouth resuscitation and no amount of compressions/oxygen can substitute actual defibrillation via an AED or whatever

Mouth to mouth actually doesn't do anything which is why they stopped teaching it over a decade ago.
Chest compressions on the other hand do work.

The purpose of CPR is to keep oxygenated blood continuing to circulate through the body. Mouth to mouth is fairly pointless.

it's too risky to perform cpr in the era of covid imho

Google waveform capnography, TC

god i hate this fucking board

Nothing compared to Twitter, where I routinely deal with people who think masks cause brain damage from hypercapnia.

i wasn't shitting on tc, i was shitting on the people coming in here just to be douchebags
it bothers them so much that tc doesn't know something yet they waste time not explaining it. truly they are very smart

If there's one thing I've learned from patients, it's that you should never overestimate the layman's understanding of biology, and that a lack of knowledge is not a lack of intelligence.

What?

I have to maintain a CPR (or BLS) certification and it requires doing the training every 2 years, and what Tropicalwood is saying is true. The last course I took, they did have us practice doing the mouth-to-mouth but there was a bigger emphasis on doing more chest compressions and less emphasis on doing the mouth-to-mouth portion. It was basically taught as a way to get you to stop pumping and listen / feel for signs of breathing and get a couple second rest in before you keep pumping again.

Myth: Proper CPR technique should include frequent use of mouth to mouth in between compressions.
In fact, the 2010 guidelines set out by the American Heart Association (AHA) do not recommend breathing for someone while performing CPR (and not for your health, as you might think, but for the person experiencing cardiac arrests chances of survival). If youre a person who was trained in CPR a long time ago, you might be familiar with the once staple 15 chest compressions then 2 breaths. If you followed the 2005 guidelines, then youre familiar with the 30 compressions then 2 breaths technique. In both cases, you should throw those out the window.
In 2010, ILCOR (International Liaison Committee on Resuscitation), reviewed hundreds of studies and found that breathing just wasnt necessary for people when doing CPR. Even for advanced medical personnel, like paramedics and doctors, breathing for someone in cardiac arrest has a limited role. The science behind this seemingly huge shift in treating someone has been around for over a decade, but it has only been recently that people in the U.S. have been paying attention (many European countries changed their recommended method well before the United States).
