YSK - for all the things that can make your life easier!

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with YSK.

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.



Rule 2- Your post body text must include the reason WHY YSK:

In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-YSK posts.

Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you harass or discriminate against any individual member, you will be removed.

If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- The majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.



Rule 11- Posts must actually be true:

Disinformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated. We are not here to ban people who said something you don't like.



Rule 12- Linking directly to a video as a source is not acceptable.

Video only posts are responsible for an outsized portion of rules violations. Your post must contain text and meet the requirements of the previous rules.



Rule 13- If you file a report, include what specific rule is being violated and how.

On OpenStreetMap, there's an emergency=defibrillator object. It can be tagged with information like opening hours (e.g. if it's inside a location that's only open certain hours), a description of the location ("at the front desk"), etc.

For example, on the Android/iOS app OsmAnd, you can select 'Defibrillator' as a point of interest (POI) Additionally, choosing 'Healthcare' POI type will show not just hospitals, clinics, etc., but also AED locations.

Other emergency devices, like emergency phones, are also mappable.


Why YSK: quick access to defibrillators can save lives and significantly improve quality-of-life outcomes. The more complete this data is, the more useful somebody can actually expect it to be in an emergency. Even if the data isn't queried during the emergency, seeing it on the map could help users know where they are ahead of time.

Depends where you live. Pretty sure here you need a code to open it which you can get while calling for an ambulance and they direct you to the nearest one.

[–] cynar@lemmy.world 12 points 1 week ago

It's a mix here. Those in private businesses tend to be open and easy to grab. The ones in a box on a street corner are code locked.

I suspect it makes sense. The slight delay would be fairly minimal. You are likely on the phone to emergency services already.

It's quite effective at stopping people messing with them however. Unfortunately, it only takes a few idiots to ruin things. Both thieves and bored teenagers could take an interest in them, and render them useless. A simple code lock makes it clear it's not to be touched without need.

I've not looked closely enough to see if any have a "break glass" type access system as well.

Wow, that sucks. A few minutes can be the difference between life and death during these events. I would be so fucking mad (and litigious) if my wife died because someone couldn't get the AED open since they didn't have some magic code.

Here, they're programmed not to shock if they don't detect a shockable heart rhythm, so there's pretty low risk as long as the spoken instructions are listened and adhered to. They were even easier to use than I thought they would be when I took my first aid training.

Why is someone looking for an AED and not calling for an ambulance? Delayed ambulance response is more likely to result in death.

[–] bumblefumble@mander.xyz 9 points 1 week ago

The person getting the AED and the person on the phone with emergency services might not be the same.

If I have to choose between going for an AED that is close by and I know the location of and calling for an ambulance, I'm going for the AED. If I can call the ambulance on the way, great, if not, I'll call it after the AED is applied. Even better would be to dial emergency services on speaker while I'm doing CPR and send someone else for the AED.

Every minute your brain goes without oxygen your chances of survival goes down by 10%. CPR is your best chance of survival, and AED is your next best chance. An ambulance can do a lot of things, but even with EMS the best things they can do to improve survival rates are early defibrillation and good CPR, and even with great response times they're probably several minutes out.

[–] HerbGrower@slrpnk.net 0 points 1 week ago (1 children)

The ambulance has drugs that you and the AED don't. Not every cardiac arrest is even shockable in the first place either.

Although even with all that, they will probably still die. Its just that having that stuff gives a small chance at survival.

[–] lonefighter@sh.itjust.works 2 points 1 week ago

I'm well aware of that. I do this for a living. But the AED and CPR still give a much better chance of survival than all the drugs in the world. Statistics don't lie and there's no bringing back someone whose brain has been deprived of oxygen for too long. I mean, you might bring them back to life, but they'll be a vegetable in a nursing home for the rest of their life.

[–] Tar_alcaran@sh.itjust.works 6 points 1 week ago (1 children)

Can't really speak for most places, but here in the Netherlands, you can sign up for a service/app that alerts nearby CPR-certified people when there's a call. It will tell you to either go to the location, or grab an AED first and then go. If you need a code/key/whatever, that's also listed.

[–] HerbGrower@slrpnk.net 2 points 1 week ago

I remember thinking of such a system for voluntary first aiders. We don't have it here. Also for more than just CPR. Sometimes an ambulance is called out because someone fell and it takes hours if there are higher priority things. Someone else who lives nearby could potentially help in that case if they knew about it.

I know my first aid certificates are all long expired now but I haven't really had a need to update them and it costs money which I no longer have anyone else willing to pay for. Got my last one on scheme for unemployed people over a decade ago. 99% of the scheme was bullshit but first aid was genuinely useful to be training people on.

I had done first aid before so for me it was more of a renewal but for many they had no experience at all. Did get to play with the CPR dummies which I hadn't on previous first aid courses.
