Topic Synopsis
This element covers the essential knowledge and practical skills required to safely administer oxygen therapy in pre-hospital emergency care, specifically within a fire and rescue context. It includes understanding clinical indications, contraindications, delivery devices, and flow rates in line with current UK resuscitation guidelines. Mastery ensures effective management of hypoxia in trauma and medical emergencies, supporting airway management and patient stabilisation until handover to ambulance services.
Key Concepts & Core Principles
- Primary Survey and CABCDE approach: Catastrophic haemorrhage, Airway, Breathing, Circulation, Disability, Exposure – a systematic method to identify and treat life threats in order of priority.
- Cardiac arrest management: High-quality CPR, early defibrillation with an AED, and supraglottic airway insertion (e.g., i-gel) as per UK resuscitation guidelines.
- Haemorrhage control: Application of tourniquets for life-threatening limb bleeding and haemostatic dressings for junctional wounds, including correct indications and risks.
- Spinal motion restriction: Use of cervical collars and longboards when spinal injury is suspected, balancing immobilisation with the need for rapid transport.
- Scene safety and situational awareness: Dynamic risk assessment, use of personal protective equipment (PPE), and communication with other emergency services.
Exam Tips & Revision Strategies
- Always begin with a structured primary survey; oxygen therapy is part of the breathing assessment and management, not a standalone skill.
- Memorise the key JRCALC oxygen administration guidelines—know the indications, target saturations, and device choices by heart.
- During practical assessments, verbalise your actions clearly, including safety checks, flow adjustments, and re-assessments, to demonstrate understanding and competence.
- Practice calculating cylinder duration: (cylinder pressure in bar × cylinder factor) ÷ flow rate in L/min; this is often a written or oral question.
- Link oxygen therapy to the wider context of emergency care: it stabilises the patient but is only one component—state when further interventions or escalation are needed.
Common Misconceptions & Mistakes to Avoid
- Applying high-flow oxygen indiscriminately to all patients, ignoring the potential harm in conditions like COPD where controlled oxygen therapy is indicated.
- Failing to check the oxygen cylinder for adequate pressure and secure connection before administration, leading to delays or equipment failure.
- Forgetting to monitor oxygen saturation continuously after initiating therapy, risking over- or under-oxygenation.
- Using incorrect mask types or flow rates for the clinical scenario, such as a simple face mask instead of a non-rebreather for critically hypoxic patients.
- Neglecting infection control when setting up reusable equipment, or not disposing of single-use items properly.
Examiner Marking Points
- Award credit for correctly identifying clinical indications for oxygen therapy, such as hypoxia, major trauma, or carbon monoxide poisoning, referencing JRCALC or local protocols.
- Expect demonstration of selecting and setting up appropriate oxygen delivery devices (e.g., non-rebreather mask, bag-valve-mask) and adjusting flow rates accurately for the patient’s condition.
- Assess candidate’s ability to monitor oxygen saturation using pulse oximetry and interpret readings to titrate therapy, ensuring safe SpO2 targets (e.g., 94–98% or 88–92% in COPD patients).
- Look for evidence of safety checks on oxygen cylinders, including confirming cylinder type (e.g., CD, ZD), checking pressure gauge, and calculating remaining duration.
- Award marks for effective communication—explaining the procedure to the patient, reassuring them, and documenting therapy details accurately for clinical handover.
