Practical First Aid Knowledge: Essential Skills That Everyone Should Know

For Businesses, Nursery Staff, Teachers, Sports Clubs & Everyday Heroes

Emergencies don’t wait for the “right” time; in fact, they can strike anywhere. For example, they may happen in the classroom, at work, during sports practice, or even at home around the dinner table. In those moments, a colleague might suddenly collapse, a child could choke on their lunch, or perhaps a teammate takes a bad fall on the pitch.

In that split second, people often look around, unsure of what to do. However, imagine if you could step forward confidently instead. In that case, you become the calm voice that guides the situation, providing life-saving care while everyone else freezes.

That’s the power of practical first aid knowledge.

At Kernow First Aid, we believe everyone—businesses, nursery staff, teachers, sports clubs, and families—should have the confidence to act in those critical moments. You don’t need to be a doctor or paramedic. With the right training, youcan be the difference.

To help you feel more confident, this guide will provide an overview of the most important first aid skills, explain why they matter, and show you how to prepare yourself effectively.

Core Life-Saving Skills

These are the foundation of first aid. They’re the skills most likely to save a life.

CPR for Adults, Children, and Infants

In situations where the heart has stopped, CPR (Cardiopulmonary Resuscitation) is crucial because it keeps oxygen flowing to the brain and vital organs until professional help arrives.

• Adults: Push hard and fast in the centre of the chest—about 5–6 cm deep at a rate of 100–120 compressions per minute. Add rescue breaths if you are trained and comfortable.

• Children: Use one hand for compressions. Their bodies are smaller and need less force.

• Infants: Use just two fingers and give very gentle breaths.

 Imagine this: You’re in the staffroom when a colleague collapses. They’re not breathing. You call 999, start CPR, and keep going until the paramedics arrive. That early action could double or even triple their chance of survival.

Many people hesitate because they fear “getting it wrong.” But here’s the truth: any attempt is better than doing nothing.

At Kernow First Aid, we use advanced CPR manikins that give you real-time feedback on your technique. This ensures you leave training confident in your ability to save a life. Read more about how cutting-edge CPR feedback technology is transforming our courses here.

Using an Automated External Defibrillator (AED)

AEDs are increasingly found in schools, offices, gyms, and community spaces. They’re designed to be simple: switch them on, and they talk you through each step.

In sudden cardiac arrest, every minute counts. Survival rates drop by 10% for every minute without defibrillation. Early CPR combined with AED use is the most effective way to save a life.

We often see people afraid to touch AEDs, worried they’ll “do it wrong.” Training shows you just how easy and safe they are to use.

The Recovery Position: When and How to Use It

If someone is unconscious but breathing, putting them in the recovery position helps keep their airway clear.

It’s a simple manoeuvre: roll them onto their side, tilt their head slightly back, and position their arm and leg for support. In our courses, we practise this step-by-step so it becomes muscle memory.

Recognising and Responding to Heart Attacks

Heart attacks don’t always look like dramatic TV scenes.

Signs can include:

For teachers, coaches, or business managers, recognising the signs quickly could save a colleague’s life.

Recognising and Responding to Strokes

Speed is critical with strokes—the faster the treatment, the better the outcome.

Use the FAST test:

• Face: Is one side drooping?

• Arms: Can they raise both arms?

• Speech: Is their speech slurred?

• Time: Call 999 right away.

Emergency Situations

Emergencies are unpredictable, but preparation means you can act instead of panic.

First Aid for Choking (Adult, Child, Infant)

Choking is frightening, but quick, decisive action saves lives.

• Adults/Children:Start with 5 back blows. If that doesn’t work, move to abdominal thrusts.

• Infants: Support the baby on your arm, give 5 back blows between the shoulder blades, then 5 chest thrusts. Never use abdominal thrusts on babies.

Training with manikins makes this second nature, so when a child suddenly starts coughing at lunchtime, you know exactly what to do.

First Aid for Severe Bleeding and Shock

A major bleed can become life-threatening in minutes.

1. Apply firm, direct pressure.

2. Use a clean cloth or dressing.

3. Keep the casualty lying down to reduce shock.

Signs of shock include pale, cold skin, rapid breathing, and confusion. Acting quickly keeps the casualty stable until paramedics arrive.

First Aid for Seizures and Epileptic Episodes

Seizures can be distressing to witness. The key is to keep the casualty safe.

• Do not restrain them.

• Protect their head with something soft.

• Move nearby objects away.

• Time the seizure (over 5 minutes = call 999).

Teachers and sports coaches often encounter seizures; knowing when to call for help is vital.

What to Do Before the Ambulance Arrives

Those minutes before professional help arrives can feel endless. What you do matters:

• Keep the casualty safe.

• Monitor breathing and responsiveness.

• Stay calm and reassure them.

One of the most important parts of training is knowing when the situation is serious enough for emergency services. Read our guide on when to call 999 as a first aider here.

First Aid for Unconscious Casualties

If someone is unconscious, check:

* Are they responsive?

* Are they breathing normally?

If not, begin CPR. If yes, place them in the recovery position.

Common Injuries

Not every situation is life-threatening, but knowing how to respond to everyday injuries prevents complications and reassures the casualty.

• Cuts, Scrapes, and Grazes: Clean gently, apply a sterile dressing. Don’t forget gloves if available.

• Burns and Scalds: Cool under running water for at least 20 minutes. Never apply creams, ice, or butter.

• Nosebleeds: Sit upright, lean forward, pinch the soft part of the nose for 10 minutes. Don’t tilt the head back!

• Broken Bones, Sprains, and Strains: Immobilise the area, apply ice wrapped in a cloth, and seek medical attention.

• Eye Injuries:** Flush with clean water, cover with a sterile dressing. Never rub the eye.

Practical training helps you distinguish between what can be treated on-site and what requires professional care.

Environmental Conditions

Nature can be just as dangerous as accidents indoors.

• Hypothermia and Frostbite: Wrap casualties in blankets, warm them gradually. Avoid direct heat.

• Heat Exhaustion and Heatstroke: Move to a cool area, give fluids, apply damp cloths. Heatstroke requires 999 immediately.

• Drowning and Near-Drowning: Prioritise your own safety. Once the casualty is out, check for breathing and start CPR if needed.

• Electrical Shock: Switch off the power before approaching. Then assess breathing and injuries.

• Poisoning: Call 999, identify the substance if possible, but never induce vomiting.

Sports clubs, outdoor education centres, and workplaces benefit hugely from training in these areas.

Bites, Stings, and Allergies

Reactions vary from mild discomfort to life-threatening emergencies.

• Insect Stings and Animal Bites: Remove stingers, clean thoroughly, seek help for deeper wounds.

• When it comes to snake bites, the first priority is keeping the casualty as still as possible, because any movement can cause the venom to spread more quickly. Instead, focus on staying calm and controlling the situation. Most importantly, avoid common myths—don’t cut the wound, don’t try to suck out the venom, and don’t apply a tourniquet, as these actions can make things worse.

• Anaphylaxis: Look for swelling of the lips, face, or throat; difficulty breathing; dizziness.

• Using an Epipen:Inject into the outer thigh immediately. Quick action can save a life.

First aid isn’t just for adults. Kids can learn how to respond too. Discover our Mini Medics First Aid courses for children here.

Preparedness and Everyday Safety

First aid isn’t just about emergencies—it’s about being ready.

• How to Build a First Aid Kit:** Include plasters, bandages, gloves, antiseptic wipes, scissors, and a face shield for CPR. Tailor kits for workplaces, nurseries, and sports teams.

• Why First Aid Matters in Daily Life:** You never know when a child, colleague, or teammate might need help.

• Staying Calm in Emergencies:** Training helps you stay focused and confident when others panic.

• Top First Aid Mistakes:** Tilting the head back in nosebleeds, using butter on burns, delaying 999 calls.

• Why Training Matters:** Skills fade. Refresher courses keep you confident and capable.
