Airway, Breathing and Circulatory Failure
Stabilise advanced respiratory and cardiovascular emergencies through definitive support.
How to prepare for MRCEM SBA
Build clinical synthesis across stable adult care, resuscitation, injury, paediatrics, procedures and complex decisions while preserving the full RCEM clinical-syllabus breadth.
Core concepts
Concept 1
Airway obstruction, respiratory failure, ventilation, severe asthma, pulmonary oedema, arrhythmia, acute coronary syndromes, cardiac arrest and post-resuscitation care.
Exam cue: Identify diagnosis, investigation, immediate treatment, longer management, disposition or professional action in the lead-in.
Concept 2
Integrate physiology, rhythm, blood gas, ultrasound and response to select airway, ventilation, electrical or circulatory intervention.
Exam cue: Use acuity, age, physiology, time course, comorbidity and response to treatment to rank plausible options.
Concept 3
Recognise peri-arrest deterioration, failed oxygenation or ventilation and reversible causes of cardiac arrest.
Exam cue: Choose the single fully correct action at this point in care and know when senior, specialty or critical-care escalation is required.
Concept 4
Use the current Year 1-3 RCEM capabilities and the full clinical syllabus at the understanding-and-applying level expected before higher specialist training.
Risk pitfalls and guardrails
Following an algorithm mechanically without recognising the underlying physiology, contraindication or failure of response.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Choosing a true statement that does not answer the exact time point or clinical task.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Inventing a paper-specific or subcategory weighting that RCEM has not published.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Memory anchors
Airway, Breathing and Circulatory Failure: scope
Airway obstruction, respiratory failure, ventilation, severe asthma, pulmonary oedema, arrhythmia, acute coronary syndromes, cardiac arrest and post-resuscitation care.
Airway, Breathing and Circulatory Failure: clinical synthesis
Integrate physiology, rhythm, blood gas, ultrasound and response to select airway, ventilation, electrical or circulatory intervention.
Airway, Breathing and Circulatory Failure: safety boundary
Recognise peri-arrest deterioration, failed oxygenation or ventilation and reversible causes of cardiac arrest.
Airway, Breathing and Circulatory Failure: common trap
Following an algorithm mechanically without recognising the underlying physiology, contraindication or failure of response.
Airway, Breathing and Circulatory Failure: MRCEM SBA sequence
Identify the clinical task and acuity, synthesise history, examination and investigations, choose the safest evidence-based decision, then check disposition and escalation.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A 46-year-old man with a massive intracranial haemorrhage has GCS 6, repeated vomiting and gurgling respirations. Oxygenation improves with suction and bag-mask ventilation. What is the definitive airway plan?
A severely hypoxaemic patient needs rapid sequence intubation. He is conscious and breathing spontaneously. Which preoxygenation strategy is most appropriate?
