First Aid Course with a CPR Trainer

An online first aid course for adults and teenagers: from checking for danger and calling for help to CPR, stopping bleeding, helping with choking, stroke, burns and road crashes. Eight stages based on the European Resuscitation Council guidelines; the compression rhythm is practiced on a trainer — your phone on a cushion, or taps.

How the course works

3 steps

Start with stage one

The first five lessons are open: safety, signs of life, calling for help and a first try at the CPR rhythm.

Practice with your hands

Lessons include scenarios with a decision timer, finding the right spot on a picture and a compression trainer: a phone on a cushion counts your rate.

Pass the stage exam

Each stage ends with an exam with an 80% pass mark; mistakes come back in “Review” after 1, 3, 7, 14 and 30 days.

Learn to save a life: CPR, bleeding, choking — with practice at every step

Program: stages — 8, lessons — 41

Open lessons: 5 of 41. The other lessons, the exams and the certificate come with Premium.

Stage 1

Getting started: safety, signs of life, calling for help

Know your part, protect yourself and decide within a minute whether resuscitation is needed.

Stage 2

Someone who is unresponsive

Protect the breathing of an unresponsive person, and help with fainting and seizures.

From here on — with Premium

Stage 3

Cardiac arrest: CPR and the defibrillator

Recognize cardiac arrest, do quality CPR for minutes and use an AED.

Stage 4

Choking and children

Clear a blocked airway in adults and babies and adapt CPR for children.

Stage 5

Bleeding and shock

Stop life-threatening bleeding within minutes and support a person in shock.

Stage 6

Sudden illness

Recognize a stroke, a heart attack, low blood sugar and anaphylaxis and act in the first minutes.

Stage 7

Injuries, burns, cold, heat, poisoning

Help with fractures, head and spine injuries, burns, temperature emergencies, poisoning and bites.

Stage 8

Road crash, several casualties and support

Secure a crash scene, set priorities, support people and hand over to the crew.

What is inside

A CPR trainer in your phone

A phone on a cushion under your hands counts compressions and shows your rate on a scale with a green 100–120 per minute zone; without a sensor — by tapping. It does not measure depth, and it says so.

Decisions against the clock

Branching scenarios with an 8–15 second timer: a man collapses in a gym, a guest chokes at dinner, a runner overheats in a race — what do you do?

Based on ERC guidelines

Every instruction follows the European Resuscitation Council 2021 guidelines for basic life support, first aid and pediatric life support.

8 stages, 41 lessons

Unresponsive people, cardiac arrest and the AED, choking in adults and babies, bleeding and the tourniquet, stroke and heart attack, burns, cold and heat, road crashes and several casualties.

Spaced review of mistakes

A task you get wrong comes back at the end of the lesson and then at intervals, so the steps stay with you for months, not just until tonight.

Questions about the first aid course

Does this course replace first aid training required at work?

No. A workplace first aid certificate comes from a licensed training provider after hands-on practice on a manikin. The course helps you understand and remember the steps and practice decisions and rhythm; its certificate confirms only that you completed the course.

How can a phone count compressions?

You lay it screen-up on a firm cushion and push with your palms: the accelerometer sees every push, and the same oscillation detector as the site’s pedometer counts them and your rate. On synthetic traces with 2–4 cm of travel its average error is 0.6 compressions per minute. A phone does not check depth or hand position — only a manikin does.

Do I have to give rescue breaths?

If you are not trained or not willing to breathe into a stranger, do continuous compressions only — for an adult whose heart suddenly stopped that is what matters most. Breaths matter more for children, whose hearts usually stop after breathing fails, so the course teaches breaths for children and babies separately.

Which emergency number should I call?

112 works across the European Union and in many other countries; elsewhere the number differs — 911 in the USA, Canada and Mexico, 999 in the UK, 119 in South Korea. The first stage asks you to look up and save the number where you live.

Where are the limits of this course?

It teaches what a bystander does before the ambulance arrives and makes no diagnoses. Your progress is saved in this browser — on another device the course starts from the beginning. When in doubt, call emergency services: the dispatcher will guide you step by step.
