Basic Life Support and Automated External Defibrillation for Adults, Children and Infants in Clinical Practice
This subtopic focuses on the practical application of basic life support and automated external defibrillation for casualties of all ages within clinical environments. Learners will develop the competence to safely assess emergency situations, deliver high-quality CPR, correctly operate an AED, and manage unresponsive casualties who are breathing normally, all in accordance with Resuscitation Council (UK) guidelines. Mastery of these skills is essential for healthcare professionals to respond promptly and effectively to life-threatening emergencies in clinical practice.
Assessment criteria
Topic Overview
The Highfield Level 3 Award in Basic Life Support and Automated External Defibrillation for Adults, Children and Infants (RQF) is a regulated qualification designed for individuals working in health and social care, education, or community settings. It equips learners with the knowledge and practical skills to recognise and respond to life-threatening emergencies, including cardiac arrest, choking, and unconsciousness, across all age groups. The course covers the chain of survival, CPR techniques, and safe use of an AED, emphasising the importance of early intervention to improve patient outcomes.
This qualification is critical because cardiac arrest can happen anywhere, and immediate bystander action can double or triple survival rates. In health and social care settings, staff are often first on scene, so competence in BLS and AED use is a legal and ethical requirement under the Health and Safety at Work Act 1974 and Care Quality Commission standards. The course also aligns with UK Resuscitation Council guidelines, ensuring learners apply evidence-based practices. Mastery of these skills not only saves lives but also builds confidence in emergency situations, making it a cornerstone of vocational training in care roles.
Key Concepts
Core ideas you must understand for this topic
- →Chain of Survival: Early recognition, early CPR, early defibrillation, and post-resuscitation care – each link is vital for survival.
- →DRSABCD: Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation – the systematic approach to assessing and managing an emergency.
- →Compression-to-ventilation ratios: 30:2 for all ages (adults, children, infants) when alone; 15:2 for children and infants if two rescuers are present.
- →AED safety: Ensure no one is touching the patient during shock delivery; remove metal jewellery and clothing; use paediatric pads for children under 8 or 25kg.
Learning Objectives
What you need to know and understand
- Be able to assess an emergency situation safely Be able to provide first aid to an unresponsive casualty who is not breathing normally Be able to provide first aid to an unresponsive casualty who is breathing normally
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a systematic scene assessment that identifies hazards and ensures personal safety before approaching the casualty.
- Award credit for performing effective chest compressions at the correct depth and rate appropriate to the casualty's age, with minimal interruptions.
- Award credit for correct placement of AED pads (or paediatric pads/attenuation for children/infants) and following voice prompts accurately without delay.
- Award credit for placing an unresponsive but breathing casualty in the recovery position while maintaining an open airway and monitoring for any changes in condition.
Assessment Guidance
Guidance for achieving higher grades
- 💡Throughout practical assessments, verbally explain your actions as you perform them to demonstrate your reasoning and adherence to protocols.
- 💡Stay updated with the latest Resuscitation Council (UK) guidelines, as assessments require current techniques for both adult and paediatric BLS.
- 💡Rehearse the recovery position multiple times to ensure a confident, fluid demonstration that protects the airway and allows for continuous monitoring of the casualty.
- 💡Tip 1: In the practical assessment, demonstrate the full DRSABCD sequence aloud – examiners award marks for clear communication and systematic approach, not just physical actions. For example, say 'I am checking for danger' and 'I am opening the airway using head-tilt chin-lift'.
- 💡Tip 2: When using an AED, remember to 'stand clear' before delivering a shock. A common mistake is forgetting to check that no one is touching the patient – this is a critical safety step that examiners will penalise if missed.
- 💡Tip 3: For infant CPR, use two fingers for compressions and ensure the head is in a neutral position (not over-extended) to avoid airway obstruction. Practise on a manikin to get the depth right (4cm) and rate (100-120 compressions per minute).
Common Mistakes
Common errors to avoid in your coursework
- Confusing the sequence of DRSABCD steps between age groups, particularly forgetting to 'shout for help' before starting CPR when alone.
- Using incorrect hand placement during adult CPR, such as placing hands too low on the sternum, reducing compression effectiveness.
- Neglecting to tilt the head and lift the chin to open the airway before checking for normal breathing, leading to missed signs of respiration.
- Assuming AEDs cannot be used on children or infants; failing to recognise that standard adult pads can be used if paediatric ones are unavailable, with appropriate placement.
- Mistake: Believing you can be sued for performing CPR incorrectly. Correction: In the UK, the Social Action, Responsibility and Heroism Act 2015 protects bystanders who act reasonably in an emergency, so you will not face legal repercussions for trying to help.
- Mistake: Thinking an AED is too complicated to use without training. Correction: AEDs are designed for untrained bystanders with clear voice prompts; however, training ensures you can act quickly and confidently, especially in high-stress situations.
- Mistake: Assuming you should check for a pulse before starting CPR. Correction: For lay rescuers, the UK Resuscitation Council advises starting CPR immediately if the person is unresponsive and not breathing normally – pulse checks are unreliable and delay life-saving compressions.

Before You Start
Prior knowledge that will help with this topic
- •A basic understanding of human anatomy, particularly the heart and lungs, is helpful but not mandatory.
- •Completion of a Level 2 qualification in health and social care or first aid is beneficial as it introduces concepts like infection control and communication.
- •Learners should be physically able to perform CPR on a manikin for at least two minutes, as the practical assessment requires sustained effort.
