Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Yeah but this is referencing the movie trope where the person has a fully stopped heart and they shock it back to life. In reality applying cpr is just keeping the blood pumping to supply the brain with oxygen in the hope the body restarts the heart itself. That's why modern defib machines check the nerve impulses to see if shocking it would help. Of there is no heartbeat, it won't help and will refuse to shock. Once the body restarts the heart but the rhythm isn't correct shocking can help. The shocks also aren't huge shocks where the person violently lurches up and putting in more energy won't help either. The machine checks the rhythm and applies a series of shocks to help the nerves regain their normal pattern and thus tell the heart to pump in the right sequence and speed. Just randomly zapping will probably do more harm than good.
It's pretty nice the emergency defib machines we have all over the place these days are smart enough to help without needing to know how it does their thing. Because 80s and 90s TV and movies have muddied the water quite a bit.
