THE SCIENCE. THE DECISION. THE PATIENT.
Know why.
Show how.
A learning atlas for the changing FRCA. Connect the science to the patient, then practise explaining your decisions.
Start with oxygen deliveryLEARNING LIBRARY
Choose a question worth understanding.
56 lessons · Primary and Final filters include shared lessons
Oxygen carriage and delivery
Why a reassuring saturation can coexist with inadequate tissue oxygen delivery.
Ventilation, dead space and control
Separate the gas moving at the mouth from the gas reaching exchanging alveoli.
Respiratory mechanics
Read pressure and flow together to distinguish resistance from compliance.
V/Q mismatch, shunt and diffusion
Explain hypoxaemia using the relationship between ventilation and perfusion.
Acid–base interpretation
Identify the primary process, then test whether compensation fits.
Cardiac output and perfusion
Connect pressure, flow, preload, afterload and contractility.
Renal physiology and fluids
Use filtration and tubular handling to explain fluid and electrolyte changes.
Cerebral physiology
Understand why pressure, CO₂ and venous drainage matter to the brain.
Metabolism, endocrine function and temperature
Link the surgical stress response to glucose, energy and heat balance.
Haemostasis and transfusion reasoning
Think about oxygen carriage, clot formation and the cause of bleeding separately.
Pharmacokinetics and infusion models
Distinguish the dose needed to fill a distribution volume from the rate needed to replace elimination.
Receptors and dose–response curves
Separate potency, efficacy, affinity and the therapeutic window.
Intravenous anaesthetic agents
Choose a drug by the physiological trade-offs it creates.
Inhalational anaesthesia
Relate uptake, solubility and potency to the changing alveolar concentration.
Analgesic pharmacology
Balance analgesia with ventilation, sedation and recovery.
Neuromuscular block and recovery
Immobility is not anaesthesia, and visible strength is not complete recovery.
Local anaesthetics and toxicity
Use ionisation and sodium-channel binding to explain block and systemic toxicity.
Autonomic and vasoactive drugs
Predict cardiovascular effects without reducing a drug to one receptor label.
Airway anatomy in practice
Connect landmarks and innervation to airway protection and injury.
Neuraxial and peripheral nerve anatomy
Learn each block as a relationship between nerves, targets and nearby structures.
Gas laws, flow and resistance
Use equations with their assumptions, not as universal rules.
Oximetry, capnography and arterial pressure
Know what each monitor measures and what can make it misleading.
Machines, breathing systems and vaporizers
Follow gas from supply to patient, then follow exhaled gas out.
Ultrasound and imaging physics
Trade penetration against resolution and interpret artefacts deliberately.
Electrical safety and heat transfer
Explain hazards through current paths and energy transfer.
Statistics and critical appraisal
Translate a study result into an absolute effect and a judgement about validity.
Preoperative assessment and shared planning
Turn a list of diagnoses into a plan for this patient and this operation.
Airway strategy and rescue
Plan oxygenation, intubation, rescue and extubation as one sequence.
Emergence, recovery and postoperative problems
Explain delayed recovery as a differential diagnosis, not a single drug effect.
Regional anaesthesia decisions
Choose a technique around expected benefit, contraindications and rescue.
Acute, chronic and neuropathic pain
Assess pain in its functional and personal context.
Procedural sedation
Prepare for the level of sedation the patient may reach, not only the level intended.
Obstetric anaesthesia
Balance maternal physiology, urgency and fetal considerations.
Paediatric anaesthesia
Start with age-specific physiology, then plan with the child and family.
Cardiac disease and cardiac surgery
Describe the lesion’s physiology before naming anaesthetic drugs.
Thoracic surgery and one-lung ventilation
Predict the consequences of deliberately excluding one lung from ventilation.
Neuroanaesthesia and brain injury
Prevent avoidable secondary injury while arranging definitive treatment.
Vascular, abdominal and orthopaedic surgery
Anticipate the physiological consequences of the operation itself.
Trauma and major haemorrhage
Resuscitate and control the cause in parallel.
Sepsis and shock
Identify the cause, support organs and reassess the response.
Intensive care and organ support
Explain what support can achieve and how you will know when it is no longer needed.
Resuscitation and safe transfer
Treat transport as a period of care with constrained access and resources.
Anaesthesia outside theatre
Preserve anaesthetic standards when the environment makes access harder.
Communication, consent and professional judgement
Make decisions with the patient using information they can use.
Teamwork, handover and crisis communication
Make priorities and responsibility visible to the whole team.
Safety, quality improvement and sustainability
Turn an observed problem into a measurable change.
Safeguarding and vulnerable patients
Recognise concerns, protect immediate safety and escalate through the right route.
Learning, teaching and reflective practice
Practise retrieval, explanation and decision-making, then use feedback to change the next attempt.
Cardiac arrest and peri-arrest reasoning
Recognise arrest, begin effective treatment and search for reversible causes.
Perioperative anaphylaxis
Recognise unexplained circulatory or respiratory collapse even without a rash.
Malignant hyperthermia
Link a hypermetabolic pattern to triggering exposure and act early.
Liver, gastrointestinal function and nutrition
Connect hepatic function to drug handling, haemostasis and metabolic reserve.
Obesity, sleep apnoea and frailty
Individualise reserve, airway planning and drug response.
ECG and investigation interpretation
Use a reproducible sequence, then explain the clinical implication.
Infection prevention and antimicrobial reasoning
Prevent contamination and use antimicrobial treatment for a defined purpose.
ENT, eye surgery, burns and transplantation
Identify the feature that makes each procedure or population different.
