This is an official ODERSA website. Here’s how you know

The official domain

The address of this site ends in odersa.org. Every service the association runs sits on a subdomain of odersa.org and nowhere else. If the address in your browser’s address bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

In a session

Teaching material that is free, works offline, and asks nobody to create an account.

This game was made to be projected, argued over and interrupted. Here is how we would use it in a room, and what not to ask of it.

What the game brings to a session

A situation runs three to four minutes and stops dead on a decision. That is exactly the shape of a question put to a group: you project it, you stop on the three choices, you take a show of hands, you click, and the consequence plays out in front of everybody before the verdict.

That is what the traps are for. A group that votes overwhelmingly for “I take the helmet off” remembers the correction far better than a group that was warned in advance.

Three session plans that work

  1. A

    Show of hands, fifteen minutes

    One situation on the projector, stop on every decision, vote, click, verdict. At the end, the summary card on screen and the sources open in a tab, to show where each rule comes from. Best at the start of a session, before any theory.

  2. B

    The rhythm mini-game, ten minutes

    The cardiac arrest situation contains a rhythm test: thirty seconds of compressions to hold between 100 and 120 per minute, with fatigue making the rhythm slip. Passing the device from hand to hand around the group teaches in ten minutes why rescuers swap every two minutes.

  3. C

    Pair work, half an hour

    A whole level per pair, on phone or tablet, then a debrief: which mistake did you make, and why did it look reasonable to you? Those answers are what makes the session.

The practical constraints, no surprises

  • No account, not for you and not for the participants. Nothing to install, nothing to create, nothing to delete afterwards.
  • Genuinely offline: once a situation has been opened one time, it replays with no connection. Useful in a basement room, and it is the point of the project's tagline.
  • Installable as an app from the browser, full screen, by keyboard as well as by finger.
  • Fully playable with reduced animation, fully playable by keyboard, subtitles for every sound, body text at 18 pixels minimum outside the scenes.
  • CC BY 4.0 licence: projecting it, photocopying the cards, reusing them in a booklet, all of that is allowed as long as you credit where it comes from.

What not to ask of it

It validates nothing. There is no transferable assessment, no certificate, no group tracking: each person's dashboard lives in their own browser and stays there. If you need to record attendance or a competence, this is not the tool.

It does not replace contact with the manikin. A rhythm tapped on a screen teaches the tempo and the fatigue; it does not teach depth, or where the body really has to be. The order stays: play here, then sit a PSC1.
