Why doesn’t a defibrillator work?

In movies (and mostly cartoons), it's often used as a solution to any 'death', so it's more just misleading

  • For the heart to pump blood, the muscles need to contract in a specific pattern. This is coordinated by a part of the heart using a form of electricity.
  • When these contractions get out of sync and blood stops being pumped (ex. certain types of heart attacks), we can use a defibrillator/AED to get everything in sync again.
  • If that is not the cause of the cause of the problem, the defibrillator wont' work.

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.
