What is the difference between anaphylaxis and a severe allergic reaction?

Anaphylaxis is a severe, life-threatening allergic reaction that involves two or more body systems (e.g., skin and respiratory, or cardiovascular and gastrointestinal). It is characterised by rapid onset and can lead to airway compromise, breathing difficulties, or circulatory collapse. A severe allergic reaction, while serious, may not involve multiple systems or pose an immediate threat to life. However, any severe allergic reaction should be treated as potential anaphylaxis until proven otherwise, as symptoms can escalate quickly.

Do I need to remove clothing before using an AED?

Yes, you must remove all clothing from the casualty's chest to ensure good pad-to-skin contact. This includes removing any bras, necklaces, or piercings that may interfere. If the chest is excessively hairy, you may need to shave the area where the pads will be placed (most AED kits include a razor). Also, ensure the chest is dry – wipe away any sweat or water. Do not delay defibrillation unnecessarily, but proper pad placement is crucial for effective shock delivery.

Can I use an AED on a pregnant woman?

Yes, an AED can and should be used on a pregnant woman in cardiac arrest. The procedure is the same as for any adult, but it is important to place the pads in the standard positions (upper right chest and lower left side). If the woman is visibly pregnant, you may need to manually displace the uterus to the left to improve blood flow during CPR. The AED will not harm the fetus, and defibrillation is necessary to save the mother's life.

How long should I continue CPR before stopping?

Continue CPR until the casualty shows signs of life (e.g., breathing normally, moving), an AED is ready to analyse or shock, emergency services arrive and take over, or you are physically unable to continue. In practice, you should keep going until help arrives. If you are alone and exhausted, you may need to stop, but ideally, switch with another trained person if available. The goal is to maintain circulation and oxygenation until advanced care can be provided.

What should I do if I accidentally inject myself with an adrenaline auto-injector?

If you accidentally inject yourself, seek immediate medical help by calling 999 or 112. Adrenaline can cause side effects such as increased heart rate, palpitations, and anxiety, but these are usually temporary. Do not attempt to drive yourself to hospital. Inform the emergency services that you have received an accidental dose of adrenaline. In most cases, the effects are not life-threatening, but it is important to be assessed by a healthcare professional.

Is it necessary to remove a casualty's jewellery or piercings before using an AED?

You do not need to remove jewellery or piercings unless they interfere with pad placement. If a necklace or piercing is in the way of where a pad needs to go, you can move it aside or remove it if possible. However, do not delay defibrillation for this. The pads should be placed at least 1 inch away from any metal jewellery to avoid arcing. Similarly, if the casualty has a pacemaker or implantable cardioverter-defibrillator (ICD), place the pads at least 1 inch away from the device.

VTCT Skills Level 3 Award in Adult Basic Life Support, AED and Management of Anaphylaxis

Topic Overview

The VTCT Skills Level 3 Award in Adult Basic Life Support, AED and Management of Anaphylaxis is a specialist qualification designed for individuals working in health and social care settings who may need to respond to life-threatening emergencies. It covers the essential skills of performing cardiopulmonary resuscitation (CPR) on an adult, using an automated external defibrillator (AED) safely and effectively, and recognising and managing anaphylaxis, including the administration of adrenaline auto-injectors. This award is particularly relevant for care workers, first aiders, and those in supervisory roles, as it equips them with the confidence and competence to act decisively in critical situations.

The qualification is structured around three key areas: basic life support (BLS), which includes assessing an unresponsive casualty, performing chest compressions and rescue breaths, and placing the casualty in the recovery position; AED usage, which involves understanding when and how to apply defibrillation pads, following voice prompts, and ensuring safety during defibrillation; and anaphylaxis management, which covers recognising the signs and symptoms of a severe allergic reaction, understanding the chain of events leading to anaphylaxis, and administering adrenaline via an auto-injector. Mastery of these skills is vital because prompt and correct intervention can significantly increase the chances of survival and reduce the risk of long-term harm.

This award sits within the broader context of health and social care by emphasising the importance of emergency preparedness and person-centred care. It aligns with national guidelines from the Resuscitation Council UK and the UK Resuscitation Guidelines, ensuring that learners are trained to current best practice. By completing this qualification, students not only enhance their own professional development but also contribute to a safer environment for service users, colleagues, and the public. It is a practical, hands-on qualification that requires both theoretical understanding and physical demonstration of skills, making it essential for anyone responsible for the well-being of others in a care setting.

Key Concepts

Core ideas you must understand for this topic

→DRSABCD: The systematic approach to emergency response – Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation. This mnemonic guides all actions in basic life support.
→Chain of Survival: The four critical steps (early recognition and call for help, early CPR, early defibrillation, and post-resuscitation care) that maximise survival from cardiac arrest.
→Anaphylaxis recognition: Identifying sudden onset of symptoms such as difficulty breathing, swelling of the tongue or throat, persistent dizziness, or collapse, often with skin changes like hives or flushing.
→Adrenaline auto-injector administration: Correct technique for using devices like EpiPen, Jext, or Emerade, including the 'blue to the sky, orange to the thigh' rule and the importance of holding in place for 10 seconds.

Assessment Guidance

Guidance for achieving higher grades

💡In practical assessments, verbalize your actions step-by-step to demonstrate knowledge of the protocols and rationales.
💡Remain calm and methodical; assessors are looking for safe and effective practice according to current UK Resuscitation Council Guidelines.
💡When demonstrating CPR, maintain a steady rhythm and avoid interruptions; quality of compressions is key.
💡For anaphylaxis management, clearly state when and how you would administer an adrenaline auto-injector, and be aware of the correct injection site (usually the outer thigh).
💡Always practice within your scope of competence and be prepared to explain what additional help you would seek (e.g., paramedics, second auto-injector after 5 minutes if no improvement).
💡When demonstrating CPR, ensure you verbalise your actions clearly, especially the ratio of 30 compressions to 2 breaths, and the depth (5-6 cm) and rate (100-120 per minute) of compressions. Examiners look for smooth, confident sequences that follow the DRSABCD algorithm without hesitation.
💡For AED use, remember to state that you would 'power on the AED and follow the voice prompts' – do not just place pads and press shock. Also, emphasise safety checks: ensure no one is touching the casualty, and that the chest is dry and free of excessive hair before pad placement.
💡In anaphylaxis management, be specific about the injection site (mid-outer thigh) and the need to call 999 or 112 immediately after administering adrenaline. Also, mention that a second dose can be given after 5-10 minutes if no improvement, but only if you have a second auto-injector.

Common Mistakes

Common errors to avoid in your coursework

Not checking for dangers before approaching the scene, compromising personal safety.
Performing chest compressions too slowly, too shallow, or with incorrect hand position.
Forgetting to call emergency services or sending for the AED before starting CPR.
Failing to tilt the head back adequately when giving rescue breaths, leading to ineffective ventilations.
Placing the AED pads incorrectly (e.g., on a pacemaker site) or not removing medication patches.
Confusing the signs of anaphylaxis with less severe allergic reactions, delaying life-saving treatment.
Misconception: You should always give two rescue breaths before starting chest compressions. Correction: In adult BLS, if you are untrained or unwilling to give rescue breaths, you can perform compression-only CPR. However, if trained and able, give 30 compressions followed by 2 breaths, but do not delay compressions for breaths.
Misconception: Anaphylaxis always involves a rash or skin symptoms. Correction: While skin changes are common, anaphylaxis can present without them. Respiratory or cardiovascular symptoms alone (e.g., stridor, hypotension) can indicate anaphylaxis, so always assess the whole picture.
Misconception: AEDs are dangerous and can shock someone who is not in cardiac arrest. Correction: Modern AEDs are designed to only deliver a shock if they detect a shockable rhythm (ventricular fibrillation or pulseless ventricular tachycardia). They will not shock a person with a normal heart rhythm, making them safe for use by untrained bystanders.
