A calm, plain-English guide to the first aid basics that matter most - the DRABC approach, CPR awareness, choking and bleeding - plus why a hands-on course beats anything you can read.
Most people will face a first aid situation at some point - a relative who collapses, a child who chokes, a colleague with a deep cut - and the difference between freezing and acting often comes down to knowing a few basics. This is a plain-English guide to the first aid everyone should have in their head. It is general information, not a substitute for proper training or medical advice, and the single best thing you can do is book a hands-on course. But knowing the fundamentals is far better than knowing nothing.
First aid is the immediate help you give someone who is injured or suddenly unwell, before professional medical care arrives or takes over. Its goals are simple and worth remembering as the "three Ps": preserve life, prevent the situation getting worse, and promote recovery.
You are not expected to be a paramedic - only to keep someone as safe as possible, get the right help on the way, and do a few high-value things well. In a serious emergency in the UK, that nearly always starts with calling 999 (or 112, which also works) and asking for an ambulance.
When you come across someone who has collapsed, panic makes you skip steps. A simple sequence keeps you on track. The most widely taught version is DRABC.
| Letter | Stands for | What you do |
|---|---|---|
| D | Danger | Check the area is safe for you and them before approaching |
| R | Response | Gently shake the shoulders and ask loudly, "Are you OK?" |
| A | Airway | Tilt the head back and lift the chin to open the airway |
| B | Breathing | Look, listen and feel for normal breathing for up to 10 seconds |
| C | Circulation | Once help is called, treat serious bleeding and shock |
The first letter is the most important and the most often forgotten: Danger. A hero who becomes a second casualty helps no one. Watch for traffic, electricity, fire, water or anything else that could injure you.
If the person responds, leave them where they are if it is safe, find out what is wrong and get help if needed. If they do not respond, shout for help and move quickly to checking their breathing.
If someone is unresponsive but breathing normally, the priority is to keep their airway clear, because an unconscious person lying on their back can choke on their tongue or vomit. Rolling them onto their side into the recovery position does this.
Broadly, you place the near arm out at a right angle, bring the far hand against their cheek, bend the far knee and use it to roll them towards you onto their side, then tilt the head back so the airway stays open. Call 999 and keep checking that they are still breathing until help arrives. The exact technique is far easier to learn by practising than by reading - one more reason a course pays off.
If an adult is unresponsive and not breathing normally (occasional gasping is not normal breathing), they need cardiopulmonary resuscitation (CPR) without delay. This is the headline skill of first aid, and acting fast genuinely saves lives.
Keep going until emergency services take over, the person starts breathing normally, or you are too exhausted to continue. CPR for children and babies differs (it begins with rescue breaths and uses gentler compressions), which is exactly the kind of detail a course covers properly. The same body that produces this guidance also explains how the immune system works in keeping us well day to day, but in a cardiac arrest it is your hands that matter most.
A blocked airway is frightening and fast-moving. The response depends on whether the person can still move air.
Choking advice differs for babies (back blows and chest thrusts, never abdominal thrusts), so treat infants differently - another reason to train.
Heavy bleeding looks alarming but usually responds well to simple, firm action. The principle is pressure.
Keeping the person warm, calm and lying down helps guard against shock, a dangerous drop in circulation. Knowing the signs - pale, clammy skin, a fast pulse, confusion - and acting on them complements other everyday health knowledge such as understanding your blood pressure.
You do not need much. A basic kit, kept somewhere everyone knows, makes you far readier:
Pair it with the habit of looking after yourself day to day - the kind of small choices covered in the benefits of walking and broader mental health basics.
Reading builds awareness, but it does not build skill. Chest compressions are more tiring than people expect; the recovery position is fiddly the first time; an abdominal thrust needs practice to do safely. A few hours with a trainer from St John Ambulance or the British Red Cross, practising on manikins, turns vague knowledge into something your hands remember under pressure. Many courses are inexpensive, and some employers fund them.
First aid comes down to staying calm and doing a few things well: check for danger, call 999 early, follow DRABC, put a breathing but unresponsive person in the recovery position, start CPR if someone is not breathing, clear a choking airway with back blows and thrusts, and stop serious bleeding with firm pressure. This article gives you the map; a hands-on course gives you the skill. Learn the basics, keep a simple kit at home, and book the training - it is one of the most useful few hours you will ever spend.
