First Aid Principles Without Pretending to Replace Training

First aid is not about performing every possible procedure. It is about protecting yourself, recognising immediate threats, calling for help early and giving simple support within your competence.

First aid is immediate help given to someone who is ill or injured before professional care is available. It can be provided by anyone, but it should remain within that person's knowledge, training and available support. The purpose is simple. Make the situation safer, call for help, support essential body functions and prevent avoidable worsening. Start with scene safety Look for danger before approaching. Traffic, fire, electricity, chemicals, unstable structures, violence and water can place the helper at risk. Do not create a second casualty. Move closer only when it is reasonably safe, and call the emergency services when specialist rescue is needed. If someone is in water, do not enter unless you are trained and it is safe. Reach or throw flotation from a safe position and call 999. A simple first assessment A structured assessment helps you focus on priorities. The professional term ABCDE stands for airway, breathing, circulation, disability and exposure. A lay responder can begin more simply. Check safety, ask for a response, assess whether breathing is normal, look for life threatening bleeding and call for help early. Responsiveness means whether the person reacts to voice or gentle touch. Do not shake someone forcefully, particularly after a significant fall or collision. If the person is unresponsive Call 999 and put the phone on loudspeaker. Open the airway as the call handler directs and look for normal breathing. Gasping or irregular breaths are not normal. If the person is unresponsive and not breathing normally, begin CPR and use an automated external defibrillator, or AED, as soon as possible. If the person is unresponsive but breathing normally, place them in the recovery position when appropriate. Keep checking their breathing because the situation can change. When major trauma is suspected, avoid unnecessary movement and follow the call handler. Airway and breathing always take priority if the person cannot breathe safely. Severe bleeding Life threatening bleeding may pour, spray, soak through clothing or continue despite initial pressure. Call 999 and press firmly and continuously on the bleeding site. Use a dressing or clean cloth when available. If an object is embedded in the wound, do not pull it out or press directly on it. Apply pressure around the object. Do not keep lifting the dressing to check. Maintain pressure and follow the call handler's instructions. Tourniquets and specialised dressings can save lives in selected injuries. They require correct use, so use them only when trained or specifically directed by emergency services. Choking in an adult A person with an effective cough should be encouraged to keep coughing. Do not slap their back while they are coughing effectively. Suspect severe choking when the person suddenly cannot speak, breathe or cough effectively. Ask, "Are you choking?" Give up to five back blows. If these do not work, give up to five abdominal thrusts. If the blockage remains after five abdominal thrusts, call 999 and continue alternating five back blows with five abdominal thrusts. If the person becomes unresponsive, begin CPR. Never perform a blind finger sweep inside the mouth. You may push the object deeper or injure the person. Babies, children, pregnant adults and people whose abdomen cannot be encircled require modified techniques. Practical first aid training teaches these differences. Burns and scalds Move the person away from the heat source when safe. Cool the burn under cool or lukewarm running water for at least 20 minutes. Do not use ice, iced water, butter, creams or greasy substances. These can worsen tissue injury or interfere with assessment. Remove jewellery and loose clothing near the burn before swelling develops. Do not remove anything stuck to the skin. After cooling, cover the burn loosely with cling film laid over the area or a clean non fluffy dressing. Do not wrap cling film tightly around a limb. Call 999 for severe burns, breathing problems, major electrical or chemical injury, or a person who appears seriously unwell. NHS 111 can advise when the required level of care is uncertain. Seizures During a convulsive seizure, protect the person from nearby danger and cushion their head. Do not restrain their movements and do not place anything in their mouth. Note the start and finish time. After the convulsions stop, check breathing and use the recovery position when appropriate. Call 999 if it is the person's first known seizure, it lasts more than five minutes, repeated seizures occur without recovery. The person is seriously injured, the seizure occurred in water, the person is pregnant, or breathing remains difficult after the movements stop. Some people with epilepsy have an emergency care plan and prescribed rescue medicine. Follow the plan only when you have been trained to do so. Severe allergic reactions and personal medicines A severe allergic reaction can rapidly affect the airway, breathing or circulation. Call 999 and help the person use their own adrenaline auto injector if it is available. Only use medicines or equipment that you are trained to use, that belong to the person, or that the emergency service directs you to use. Do not give food, drink or tablets to someone who cannot swallow safely. Stay, observe and hand over Stay with the person until help arrives unless remaining places you in danger. Recheck breathing, responsiveness and bleeding, and report any change to the call handler. Tell responders what happened, what you observed, when events occurred and what first aid was given. Include any medicines or devices used. Why practical training matters Reading can explain priorities, but it cannot teach hand position, pressure, timing or confidence as effectively as supervised practice. Skills such as CPR, AED use, choking response and recovery positioning improve with demonstration and rehearsal. Accredited first aid training also teaches adaptations for babies, children, pregnancy, disability, trauma and different settings. This lesson prepares understanding but does not certify competence. Follow the 999 call handler during a real emergency. Use this page to understand principles, not as a substitute for practical training or professional advice.

Safe first aid means checking danger, calling early, supporting breathing and circulation, controlling obvious threats and staying within your competence.
