Topic Synopsis
This unit provides learners with the essential knowledge and practical skills to assess emergency situations safely and deliver immediate life-saving interventions, including cardiopulmonary resuscitation (CPR), automated external defibrillator (AED) use, and the management of anaphylaxis for adult, child, and infant casualties. It emphasises the correct sequence of actions, the differences between age groups, and the importance of prompt, confident application in real-world emergencies to improve survival outcomes.
Key Concepts & Core Principles
- The Chain of Survival: Early recognition, early CPR, early defibrillation, and post-resuscitation care are critical for improving outcomes in cardiac arrest.
- DRSABCD: Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation – the systematic approach to assessing and managing an unresponsive casualty.
- Anaphylaxis recognition: Sudden onset of breathing difficulties, swelling (especially of the face and throat), and circulatory collapse; requires immediate administration of adrenaline via auto-injector.
- Age-specific techniques: Differences in CPR ratios (30:2 for all ages, but compression depth and hand placement vary for infants, children, and adults) and AED pad placement (anterior-lateral for adults, anterior-posterior for children under 8).
- Safe use of an AED: Ensuring no one is touching the casualty, checking for chest hair or medication patches, and following voice prompts without delay.
Exam Tips & Revision Strategies
- During practical assessments, verbalise each step clearly (e.g., 'I am checking for danger, putting on gloves, opening the airway, looking, listening and feeling for breathing for up to 10 seconds') to demonstrate understanding even if the assessor observes the actions.
- Memorise the age-specific differences: adult CPR uses two hands; children use one or two hands depending on size; infants use two fingers or two thumbs with encircling technique. For AED, know when to use paediatric pads or settings (under 8 years or 55 kg).
- Practise the 'chain of survival' sequence repeatedly: early recognition and call for help, early CPR, early defibrillation. In anaphylaxis management, remember 'Adrenaline first, then ambulance' and always carry two auto-injectors.
- When using an AED during an assessment, do not turn it off if instructed by voice prompt to continue CPR; follow the prompts exactly, and ensure the casualty's chest is dry and clear of medication patches or excessive hair.
- For the recovery position, demonstrate the technique without causing injury, ensure the airway remains open (head tilt maintained), and state that you would continue to monitor breathing and keep the casualty warm.
- Check equipment and environment before starting any scenario: ensure the manikin is on a firm surface, AED trainer is present, and auto-injector trainer is in date, and remind assessor you would use appropriate barriers (gloves, face shield) in a real situation.
Common Misconceptions & Mistakes to Avoid
- Mistaking agonal gasps for normal breathing and delaying or failing to start CPR.
- Performing chest compressions with the casualty on a soft surface (e.g., bed) instead of a firm, flat surface, reducing compression depth effectiveness.
- Failing to remove clothing from the casualty's chest before applying AED pads, causing poor pad adhesion and ineffective shock delivery.
- Placing an unresponsive casualty who is not breathing normally into the recovery position instead of immediately initiating CPR.
- Failing to check for danger or wearing personal protective equipment before approaching the casualty, compromising personal safety.
- Using adult AED pads on a child or infant when paediatric pads or settings are available, potentially causing harm or ineffective therapy.
Examiner Marking Points
- Award credit for demonstrating a systematic scene assessment: identifies hazards, ensures personal and bystander safety, and wears appropriate personal protective equipment before approaching the casualty.
- Award credit for correctly checking responsiveness using the 'shout and shake' method for adults and children, and foot-tap or shoulder-tap for infants, followed by a clear call for help or emergency services.
- Award credit for opening the airway using head tilt-chin lift (or jaw thrust if trauma suspected) and checking breathing for no more than 10 seconds, recognizing agonal gasps as absent or abnormal breathing.
- Award credit for performing high-quality CPR: correct hand position (lower half of sternum for adults/children, two fingers or two thumbs for infants), depth (5-6 cm adults, at least one-third chest depth children/infants), rate (100-120 compressions per minute), allowing full chest recoil, and minimising interruptions.
- Award credit for safe and prompt AED use: activates device, exposes chest and wipes if wet, attaches pads correctly (antero-lateral for adults, paediatric pads/pad positions for children/infants), ensures nobody touches casualty during analysis and shock delivery, and follows voice prompts.
- Award credit for placing an unresponsive, breathing casualty in the recovery position, maintaining an open airway, monitoring breathing, and regualrly reassessing for any deterioration.
- Award credit for recognising anaphylaxis signs (skin changes, airway swelling, breathing difficulty, shock) and administering adrenaline auto-injector correctly: removes safety cap, holds for appropriate duration (3 seconds for EpiPen®, 10 seconds for Jext®), injects into the outer mid-thigh through clothing if necessary, and calls emergency services immediately.
- Award credit for providing aftercare: positions casualty lying down with legs raised (unless breathing difficulties necessitate sitting up), monitors vital signs, and administers a second auto-injector after 5 minutes if no improvement and ambulance not yet arrived.
