Topic Synopsis
This subtopic covers the fundamental techniques of basic life support (BLS) including cardiopulmonary resuscitation (CPR) and the safe use of automated external defibrillators (AEDs) in emergency situations encountered by fire and rescue personnel. It equips learners with the skills to manage cardiac arrest, integrate adjuncts for airway management, and ensure effective post-resuscitation care, while addressing special circumstances such as trauma or paediatric cases.
Key Concepts & Core Principles
- Primary and secondary survey: Systematic patient assessment using the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure) adapted for hazardous environments.
- Haemorrhage control: Application of tourniquets, haemostatic dressings, and pressure points to manage catastrophic bleeding, especially in entrapment scenarios.
- Airway management: Use of oropharyngeal airways, supraglottic devices, and manual manoeuvres (jaw thrust, chin lift) in patients with suspected spinal injury or smoke inhalation.
- Burns assessment and management: Estimating burn surface area using the Wallace Rule of Nines, cooling burns, and preventing hypothermia in fireground casualties.
- Crew resource management: Effective communication, leadership, and teamwork within a multi-agency response, including handover to ambulance crews using the ATMIST format.
Exam Tips & Revision Strategies
- Verbalise all actions during practical assessments to demonstrate underpinning knowledge and decision-making.
- Familiarise yourself with local fire service clinical governance and AED protocols to ensure compliance.
- In scenario-based exams, prioritise dynamic risk assessment and scene safety before patient contact.
- Use correct terminology such as 'agonal breathing', 'ventricular fibrillation (VF)', and 'return of spontaneous circulation (ROSC)' in written work.
- Understand the differences in compression-to-ventilation ratios and AED pad placement for paediatric versus adult patients.
Common Misconceptions & Mistakes to Avoid
- Inadequately releasing pressure during chest compressions leading to incomplete chest recoil.
- Misplacing AED pads over medication patches or internal pacemakers without checking for contraindications.
- Over-inflating lungs with bag-valve-mask leading to gastric distension and increased aspiration risk.
- Failing to consider spinal precautions when managing a traumatic cardiac arrest.
- Neglecting to call for immediate advanced medical support before commencing BLS in out-of-hospital settings.
Examiner Marking Points
- Correct hand placement and depth for chest compressions (at least 5-6 cm) on a manikin with complete recoil.
- Safe operation of AED including pad placement, analysis of rhythm, and delivery of shock if indicated, with verbalised safety checks.
- Effective insertion and sizing of an oropharyngeal airway with head-tilt chin-lift manoeuvre and assessment of ventilation.
- Clear, structured handover to emergency medical services, including patient status, interventions, and time of arrest.
- Identification of reversible causes (Hs and Ts) and appropriate action when assessing cardiac arrest.
