Topic Synopsis
This element focuses on the practical application of cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) skills in line with current UK Resuscitation Council guidelines. Learners will develop the competence to assess an emergency situation, deliver effective chest compressions and rescue breaths, and safely operate an AED on a casualty. Mastery of these skills is essential for responding to cardiac arrest incidents in community and workplace settings, emphasising prompt action and adherence to safety protocols.
Key Concepts & Core Principles
- Chain of Survival: Early recognition, early CPR, early defibrillation, and post-resuscitation care. Each link is crucial for increasing survival rates.
- Chest Compression Technique: Compress at least 5-6 cm deep at a rate of 100-120 compressions per minute, allowing full chest recoil. Use the heel of one hand, with the other hand on top, interlocking fingers.
- AED Safety: Ensure no one is touching the casualty when the AED analyses or delivers a shock. Remove any medication patches, and avoid using an AED near water or flammable materials.
- Recovery Position: For an unconscious casualty who is breathing normally, place them in the recovery position to maintain an open airway and allow fluids to drain.
- Rescue Breaths: Give two rescue breaths after 30 compressions, each lasting about 1 second, ensuring the chest rises visibly. Use a pocket mask or face shield if available.
Exam Tips & Revision Strategies
- During the practical assessment, verbalise every step of the primary survey (DRSABC) to demonstrate understanding and ensure no component is missed under pressure.
- If you lose count or rhythm during compressions, stay calm and adjust; assessors look for overall competency, not perfection.
- Familiarise yourself with the specific AED model used in your training centre, as operational nuances (e.g., button layout, pad cartridge) can boost confidence.
- When troubleshooting AED problems, show safe practice—check connections, pad adhesion, and battery; never compromise casualty safety.
- For post-resuscitation, clearly state how you would hand over information to paramedics using a structured approach like SBAR (Situation, Background, Assessment, Recommendation).
Common Misconceptions & Mistakes to Avoid
- Not ensuring the chest is dry and clear of medication patches or excessive hair before applying AED pads, which can hinder pad adhesion and shock delivery.
- Failing to call emergency services (or delegate the call) immediately after establishing unresponsiveness and abnormal breathing, delaying advanced care arrival.
- Interrupting chest compressions for too long during pad application or shock delivery, reducing coronary perfusion pressure.
- Placing AED pads incorrectly, such as too close together or over a pacemaker, which may reduce defibrillation effectiveness.
- Neglecting to verbalise safety checks (e.g., 'stand clear') before delivering a shock, a critical assessor observation point.
- Forgetting to remove metallic items like piercings or underwired bras that could cause arcing or burns during defibrillation.
Examiner Marking Points
- Award credit for demonstrating correct hand placement (centre of the chest) and compression depth of 5-6 cm at a rate of 100-120 per minute on an adult manikin.
- Award credit for performing a safety check of the environment and casualty assessment, including checking for response and normal breathing before initiating CPR.
- Award credit for following AED voice prompts accurately, ensuring everyone stands clear during shock delivery, and resuming CPR immediately after shock or as instructed.
- Award credit for correct placement of AED electrode pads on the bare chest, with the right pad below the right collarbone and the left pad on the left side of the rib cage.
- Award credit for carrying out post-resuscitation procedures, such as placing the casualty in the recovery position if breathing normally returns, while monitoring vital signs until emergency services arrive.
- Award credit for performing basic AED user maintenance checks, including visual inspection for damage, checking battery status and pad expiry, and recording the outcome in the equipment log.
