Explain With Confidence. Defend Your Decisions. Adapt Across All Four SOEs.
Build the confidence to explain physiology, defend anaesthetic decisions, respond to critical incidents and interpret ICU investigations. This practical guide brings together the official Structured Oral Examination format, high-yield viva topics, original examiner-style practice, and a repeatable study plan.
If you are searching for EDAIC Part II preparation books, EDAIC 2 viva questions, SOE practice cases, high-yield anaesthesia notes or a structured oral-exam study plan, this guide starts with what the examination actually asks you to demonstrate: a clear, clinically sound explanation that stands up to examiner follow-up. Knowledge matters, but so do prioritisation, safe decision-making, communication and the ability to change your plan when new facts appear.
The European Diploma in Anaesthesiology and Intensive Care (EDAIC) Part II differs from the written Part I examination. Rather than selecting answers on an MTF paper, you must think aloud, explain mechanisms, interpret findings and justify actions. A resource designed for speaking and decision defence is therefore more useful than merely rereading basic-science notes.
01 EDAIC Part II Examination Format: How the Four SOEs Work
The EDAIC Part II is a structured oral examination organised into four separate SOEs. The first two focus on applied basic sciences, while the later two assess clinical anaesthesia and critical care. Candidates are expected to communicate coherent answers, respond to prompts and adapt when the examiners explore limitations, complications or alternative approaches.
ESAIC describes four 25-minute SOEs, usually two covering applied basic sciences and two covering clinical topics. The preparation guidance describes a short preparation period before each SOE. Always check current ESAIC candidate instructions for venue, online requirements, timing and eligibility, which may change independently of the academic structure.
A polished answer is not a speech containing every fact you know. Start with the specific question, use a short logical structure and leave time for follow-up. If asked to compare two drugs, discuss the mechanism, practical indication, important contraindication and clinically significant differences instead of giving two unrelated textbook summaries. If asked for management, place safety and urgency before the exhaustive differential.
Do not confuse the EDAIC Part II SOE with the separate EDIC Part II OSCE. EDIC has a different examining body and station system. This guide and the linked EDAIC Part II eBooks are specifically for European anaesthesiology structured orals.
02 SOE 1–4: The Exam-Focused Content Map and High-Yield Revision Topics
An effective EDAIC Part II revision strategy covers all four stations while adapting depth to the kind of answer each station expects. The following map groups frequently useful preparation topics under their corresponding official SOE domains; it is a practical study aid, not a replacement for the full ESAIC syllabus.
SOE 1: Physiology, pathophysiology and applied anatomy
- Oxygen delivery and consumption: link cardiac output, haemoglobin, arterial oxygen saturation and tissue extraction; explain why a normal SpO₂ cannot exclude inadequate oxygen delivery.
- Cardiovascular physiology: preload, afterload, contractility, venous return, shock physiology and the limitations of relying on one haemodynamic number.
- Respiratory physiology: shunt versus V/Q mismatch, compliance and resistance, ventilation–perfusion relationships, CO₂ elimination and positive-pressure ventilation.
- Renal and acid–base: filtration, sodium and water handling, compensation, respiratory and metabolic disturbances and bedside interpretation.
- Applied anatomy: upper airway and laryngeal innervation, neuraxial spaces, relevant nerve blocks, circulation and clinically important risk structures.
“Oxygen delivery depends mainly on cardiac output and arterial oxygen content. I would first define these variables, then explain what happens in anaemia, hypoxaemia and low-output states, before connecting the mechanism to monitoring and treatment priorities.”
MedicoKeys EDAIC II Volume 1 is organised specifically around the morning SOEs, with mechanisms, applied anatomy, pharmacology and clinical measurement in guided oral-answer format.
SOE 2: Pharmacology, equipment and clinical measurement
- Induction agents and haemodynamics: compare effects on circulation, breathing, intracranial physiology and recovery; know why patient context changes drug choice.
- Neuromuscular blockers and reversal: mechanisms, monitoring, residual blockade risk, reversal principles and circumstances affecting the safest strategy.
- Volatile agents and opioids: pharmacokinetics, context-sensitive recovery, analgesia, adverse effects and organ dysfunction.
- Anaesthesia monitoring: pulse oximetry, capnography, blood pressure measurement, pressure transducers, gas analysis and sources of artefact.
- Equipment and safety: breathing-system faults, oxygen failure, ventilation alarms, waveform changes and how to check the patient first.
“Your capnography waveform suddenly becomes flat. What is your immediate approach? How would you distinguish disconnection, airway displacement and circulatory collapse? Which data would change your conclusion?”
SOE 3: Clinical anaesthesia, perioperative care and critical incidents
For SOE 3, a persuasive answer combines a safe plan with a clear rationale. Prepare to assess risks, choose an appropriate anaesthetic technique, describe monitoring, anticipate complications and state what would make you change course.
- Airway assessment and difficult-airway planning, including oxygenation strategy, rescue options and communication with the theatre team.
- Preoperative optimisation: comorbidity, aspiration risk, anticoagulants, relevant investigations and shared risk discussions.
- Regional, obstetric, paediatric and other subspecialty anaesthesia, always considering contraindications and local resources.
- Intraoperative hypotension, severe bronchospasm, perioperative anaphylaxis, haemorrhage, local-anaesthetic toxicity and postoperative deterioration.
- Human factors: early help, closed-loop communication, task allocation, documentation and focused reassessment.
SOE 4: Critical care, emergency medicine and image interpretation
- Shock: distinguish causes, identify inadequate perfusion and explain resuscitation, source control, vasoactive support and response targets.
- ARDS and mechanical ventilation: oxygenation/ventilation goals, compliance, driving pressure, dynamic hyperinflation, weaning readiness and escalation.
- Sepsis, organ support, acute kidney injury, electrolyte emergencies, neurocritical care, trauma and toxicology.
- Chest X-ray, ECG, ultrasound, CT, physiological waveforms, blood gases and laboratory patterns: describe before interpreting, then connect abnormalities to a safe plan.
- ICU communication: prognosis, multidisciplinary escalation, limits of treatment and compassionate shared decisions when relevant.
Name the modality and quality; describe objective findings; give the most likely interpretation and important alternative; link the interpretation to urgency, patient safety and the next action.
03 How to Answer EDAIC Part II Viva Questions Clearly and Convincingly
A strong viva answer often follows a repeatable sequence. It should make it easy for an examiner to understand what you recognise, why you believe it, what you would do and how you would respond to new information.
For a pure science question, swap the action stage for a clear mechanism, directional prediction and clinical application. For an emergency, verbalise the immediate threat, call for appropriate help and stabilise first—then expand into differential diagnosis and definitive management. The order matters more than rehearsed filler.
Do not begin with a ten-minute list of possible diagnoses when the examiner asks for the immediate response to a deteriorating patient. Conversely, do not give a treatment algorithm when the actual question asks you to explain physiology. Identify the requested task before speaking.
Practise giving a 60–90 second opening answer, then let a study partner ask “Why?”, “What if?”, “How do you know?” and “What could make this unsafe?”—four follow-ups that reveal whether knowledge is exam-ready.
04 Eight Original EDAIC Part II Viva Practice Scenarios With Model Responses
These original, independently written viva scenarios are designed for active revision. They illustrate appropriate mechanisms and structured reasoning, but are not recalled ESAIC questions or predictions of live exam content. Answer each prompt aloud before expanding the response. In real clinical practice, follow senior advice, local protocols and current authoritative guidance.
Oxygen delivery during hypotension
Opening scenario: A patient becomes hypotensive after induction. The pulse oximeter reads 99%, but peripheral perfusion is poor.
Examiner follow-up: Explain oxygen delivery (DO₂). Why might a normal saturation coexist with inadequate tissue oxygenation?
Reveal model viva response and teaching points
Suggested answer: Oxygen delivery is approximately cardiac output multiplied by arterial oxygen content. Arterial oxygen content depends chiefly on haemoglobin concentration and oxygen saturation, with a smaller dissolved oxygen component. A normal SpO₂ describes saturation, not cardiac output or haemoglobin concentration; low cardiac output or severe anaemia may still reduce overall delivery.
Defend your reasoning: Explain how cardiac output, haemoglobin, lactate trends, perfusion examination and the clinical context guide prioritised assessment rather than treating saturation as proof of adequate perfusion.
Common trap: Confusing normal arterial oxygen saturation with adequate systemic oxygen delivery.
Airway anatomy and laryngeal nerves
Opening scenario: An anaesthetist is explaining the risk of nerve injury during airway manipulation or neck surgery.
Examiner follow-up: How would you explain the relevant innervation of the larynx and the clinical implications?
Reveal model viva response and teaching points
Suggested answer: The recurrent laryngeal nerve supplies most intrinsic laryngeal muscles other than the cricothyroid; the external branch of the superior laryngeal nerve supplies the cricothyroid. The internal superior laryngeal branch supplies sensation above the vocal cords and the recurrent laryngeal nerve contributes below the cords.
Defend your reasoning: Connect motor injury with altered vocal-fold movement and airway/voice symptoms; explain how bilateral dysfunction can become an airway concern requiring prompt expert assessment.
Common trap: Giving one undifferentiated “laryngeal nerve” without distinguishing motor and sensory supply.
Neuromuscular blockade and reversal
Opening scenario: A patient has received a non-depolarising neuromuscular blocker and is approaching the end of anaesthesia.
Examiner follow-up: How do you judge recovery and discuss safe reversal?
Reveal model viva response and teaching points
Suggested answer: Use appropriate quantitative neuromuscular monitoring, interpret train-of-four findings, and choose reversal according to the agent, depth of block, patient-specific risks and current clinical guidance. Adequate recovery should be objectively demonstrated before extubation when feasible.
Defend your reasoning: Show awareness of residual paralysis, airway protection, respiratory complications, drug-specific limitations and the need to match the reversal strategy to block depth.
Common trap: Saying that visible movement or a single clinical sign alone reliably excludes residual neuromuscular blockade.
Sudden loss of a capnography trace
Opening scenario: During anaesthesia the end-tidal CO₂ waveform abruptly disappears.
Examiner follow-up: Give your immediate diagnostic framework and explain how you differentiate patient and equipment problems.
Reveal model viva response and teaching points
Suggested answer: Assess the patient and oxygenation immediately, check ventilation and airway position, inspect circuit continuity and sampling integrity, and consider serious physiological causes such as profound loss of pulmonary perfusion. Call for help if instability is present and verify the clinical findings instead of trusting a single monitor.
Defend your reasoning: Contrast disconnection or sampling-line blockage with airway displacement, severe ventilatory failure and circulatory collapse; correlate with chest movement, airway pressures, oxygen saturation and circulation.
Common trap: Assuming that every flat trace is “just a monitor fault” or proceeding to lengthy troubleshooting while a patient is unstable.
An anticipated difficult airway
Opening scenario: A patient requiring urgent surgery has predictors of difficult mask ventilation and difficult tracheal intubation.
Examiner follow-up: Present an anaesthetic plan and explain how your strategy changes if oxygenation becomes difficult.
Reveal model viva response and teaching points
Suggested answer: Clearly state the predicted airway risks, assess aspiration and physiological concerns, plan an appropriate airway approach including whether awake techniques are indicated, brief the team and prepare equipment, assistance and rescue pathways. Maintain oxygenation as the central safety priority.
Defend your reasoning: Defend the strategy with patient and procedure factors; describe clear stopping points, escalation, alternatives and the importance of checking relevant local difficult-airway guidance.
Common trap: Listing several airway devices without specifying a primary plan, backup plan or oxygenation rescue strategy.
Profound hypotension after an antibiotic
Opening scenario: Soon after intravenous antibiotic administration during anaesthesia, a patient develops severe hypotension, bronchospasm and difficulty ventilating.
Examiner follow-up: What serious diagnosis must you consider, and how do you prioritise action?
Reveal model viva response and teaching points
Suggested answer: Consider perioperative anaphylaxis promptly alongside other causes of collapse. Stop a suspected trigger where feasible, summon assistance, prioritise airway/oxygenation and circulation, give appropriate emergency treatment including adrenaline according to current protocols, and reassess response while organising ongoing support.
Defend your reasoning: Explain why the skin findings of anaphylaxis may be absent, and discuss the role of documentation, later investigation and clear communication after acute stabilisation.
Common trap: Waiting for a rash to establish anaphylaxis or spending too long obtaining a full allergy history during severe instability.
Septic shock and an evolving lactate
Opening scenario: An adult in ICU is febrile, hypotensive and confused with suspected infection, raised lactate and poor peripheral perfusion.
Examiner follow-up: Present your opening assessment and management priorities, and say how you judge treatment response.
Reveal model viva response and teaching points
Suggested answer: Prioritise ABC assessment, immediate resuscitation, timely appropriate antimicrobials, investigation of the infection source and early source control planning. Individualise fluid administration; use vasoactive support when indicated, with careful haemodynamic and organ-perfusion reassessment.
Defend your reasoning: Use dynamic examination, urine output, lactate trends, perfusion parameters, physiological response and context rather than chasing a single fixed measurement without reconsidering the cause of shock.
Common trap: Delaying source control and antimicrobials while seeking one perfect investigation or indiscriminately giving fluids despite signs of intolerance.
An abnormal chest radiograph and oxygenation
Opening scenario: An intubated ICU patient becomes hypoxaemic. A portable radiograph shows a largely opaque left hemithorax.
Examiner follow-up: How would you describe, differentiate and connect the image to immediate patient management?
Reveal model viva response and teaching points
Suggested answer: Start with the study quality, equipment and tube position, then describe opacity and whether there are signs of volume loss, shift, air bronchograms or pleural fluid. Consider collapse, large effusion, infection or other causes in clinical context; examine the patient and use appropriate bedside tests to refine the diagnosis.
Defend your reasoning: Explain why signs of volume loss may suggest atelectasis while contralateral shift or meniscus may suggest a large effusion, and match urgency to oxygenation and haemodynamic stability.
Common trap: Jumping to a single diagnosis on an unseen image without a systematic description or ignoring displaced tubes and lines.
If an intubated patient has pH 7.26, PaCO₂ 61 mmHg and HCO₃⁻ 26 mmol/L, the primary disturbance is respiratory acidosis. Your viva answer should connect the result to alveolar ventilation, check for sampling or contextual issues, and address the cause of impaired ventilation rather than only reciting the numbers.
Practise the scenarios twice: first under time pressure without looking at the answers, then again after building a compact error log. In the second run, ask a colleague to change one variable—new haemodynamic instability, unexpected drug contraindication or a new radiological finding—and test whether your answer adapts coherently.
05 An Adaptable Eight-Week EDAIC Part II Oral Examination Study Plan
A repeatable routine matters more than a rigid “best” timetable. An eight-week EDAIC II revision plan may be appropriate for candidates who already have a substantial anaesthesia and intensive-care foundation. If your baseline is different, extend or compress the plan while maintaining all four station types and regular spoken practice.
Daily viva routine: learn, speak, defend, retrieve
- 15 minutes — retrieval: close the notes and recite the previous day’s physiology, pharmacology or crisis priorities.
- 35–45 minutes — focused content: read one coherent topic from an authoritative reference or high-yield study note set.
- 25–35 minutes — speaking practice: give timed oral openings and respond to three to five examiner follow-ups.
- 10–15 minutes — error repair: note missing explanations, wrong physiological assumptions, unsafe actions, and failure to reassess.
- Short spaced return: revisit difficult questions after a delay and explain them again without prompts.
Candidate-focused tip: if you freeze while speaking, use a simple recovery sentence—“I would first define the problem, prioritise safety, and then work through the mechanism and my response.” A clear restart is better than guessing aggressively.
06 Choosing EDAIC Part II Study Notes, Viva Books and Mock Examination Resources
When comparing EDAIC Part II books, SOE viva revision resources, anaesthesia oral exam notes or mock-viva preparation, choose materials that train the actual spoken task. Dense notes alone rarely reveal whether you can explain, defend and adapt under questioning. A useful resource should include mechanisms, clinical application, original questions, examiner follow-ups, answer structures, interpretation drills and a realistic strategy for fixing weak areas.
MedicoKeys.com EDAIC Part II: what is included?
The MedicoKeys.com library contains three coordinated downloadable PDF eBooks totaling 914 pages. Each volume focuses on different SOE demands, while the full package makes it possible to rehearse one consistent answer method from science to anaesthetic emergencies and critical care.

How to judge any EDAIC II oral-exam resource
- Correct examination identity: choose EDAIC Part II SOE resources, not a written MTF-only book or the different EDIC critical-care OSCE.
- Scientific depth: the resource should explain physiology, drug mechanism, limitations and clinically important distinctions, not only provide mnemonic lists.
- Reasoning and safety: look for patient safety, contraindications, communication and escalation questions, not only perfect uncomplicated cases.
- Authentic oral practice: rehearse answers out loud, use follow-ups and challenge changed-variable scenarios.
- Readable design: meaningful red/blue/green coding and selective highlighting should make key decisions easier to locate without substituting for clinical understanding.
- Independent verification: compare time-sensitive policies and management recommendations with current official exam information and professional guidelines.
For adjacent examinations, the MedicoKeys.com EDAIC Part I written-exam library is designed for MTF Paper A/B preparation, while Primary FRCA eBooks are organised around a separate UK anaesthesia pathway. Intensive-care candidates may also explore the EDIC Part I and EDIC Part II libraries; these are distinct examinations, not interchangeable with EDAIC Part II.
If you are preparing for more than one examination, the complete MedicoKeys.com medical and healthcare exam eBook directory makes it easy to select the right dedicated library rather than accidentally purchasing content for a different exam stage.
07 Common EDAIC Part II Viva Mistakes—and How to Avoid Them
- Starting with a lecture: define the question and give a relevant first answer before expanding into the full mechanism.
- Overconfidence without limits: acknowledge uncertainty intelligently; do not invent physiological facts or management details when unsure.
- Unsafe sequencing: instability and time-critical priorities must come before exhaustive investigation.
- Not explaining comparisons: “I choose this drug” is weaker than “I choose it because these patient-specific effects and limitations matter.”
- Failing to respond to examiner prompts: new results are information, not an attack on your answer. Reassess and update the plan clearly.
- Under-practising SOE 4 images and data: describe objectively first, then interpret and link to urgency.
- Ignoring the sciences after passing Part I: SOE 1 and 2 still require active physiology, pharmacology and measurement explanations.
- Passive reading only: oral examinations reward organised thinking under questioning; practise speaking with another person.
For every weak case, keep one small note: “Question asked → mechanism missed → safest answer → examiner follow-up.” This turns mistakes into reusable high-yield material without duplicating long textbook passages.
08 EDAIC Part II Preparation FAQs
What is the EDAIC Part II examination format?
ESAIC describes four Structured Oral Examinations in a single examination day. The two morning SOEs address applied basic sciences; the two later SOEs examine clinical anaesthesia, critical care and emergency medicine. Each SOE is 25 minutes in the official preparation guidance. Check the latest candidate rules for current logistical arrangements.
What topics appear in SOE 1 and SOE 2?
SOE 1 covers physiology, pathophysiology and applied anatomy; SOE 2 covers pharmacology and clinical measurement. A good response explains mechanisms, clinically significant distinctions and limitations, rather than listing isolated facts.
What is tested in SOE 3 and SOE 4?
SOE 3 focuses on clinical anaesthesia and critical incidents. SOE 4 focuses on critical care and emergency medicine, including image interpretation. The actual examiner follow-ups can explore different variables and clinical priorities.
What is the best way to practise EDAIC Part II viva questions?
Use active spoken rehearsal. Open with a clear definition, clinical problem or priority; explain why; describe safe actions and limitations; then ask a colleague to change a variable and challenge your response. Record weak mechanisms and repeat them after a delay.
Are viva books and high-yield notes enough on their own?
No single eBook replaces clinical training, current professional guidance or independent practice. A useful viva library supplements them by organising core science, important clinical decisions, high-yield comparisons, guided questions and mock SOEs.
How does EDAIC Part II differ from EDAIC Part I?
Part I is a written multiple true/false examination across basic and clinical sciences; Part II is a structured oral examination requiring explanation, reasoning, scenario management and examiner follow-up. The MedicoKeys.com eBook libraries are separate for those different tasks.
Does the MedicoKeys.com EDAIC II library include mock vivas and image interpretation?
Yes. The live library describes guided oral drills, follow-up prompts, model response structures, full mock SOE circuits and ICU/image interpretation in its three volumes. Check the actual product listings and free previews to see the current contents.
Can I purchase EDAIC Part II volumes separately?
Yes. The three downloadable PDF volumes can be purchased separately, or as a complete package. Volume 1 covers SOE 1–2, Volume 2 concentrates on SOE 3, and Volume 3 on SOE 4 and advanced mock-viva performance.
Are MedicoKeys EDAIC Part II eBooks official ESAIC publications?
No. MedicoKeys.com is an independent educational provider. Its materials are designed for EDAIC Part II exam preparation but are not official examination questions or endorsed exam publications. Always confirm policies against current ESAIC communications.
