Airway Disease, Infection and Obstruction
Use severity, blood gases and imaging to manage asthma, COPD, pneumonia and airflow obstruction.
How to prepare for MRCP(UK) Part 2 Written
Use the official likely question distribution to protect breadth, then practise extracting decisive clinical and visual evidence before selecting one best answer.
Core concepts
Concept 1
Work of breathing, oxygenation, ventilation, fatigue, infection, airflow pattern, trigger and treatment response.
Exam cue: Life-threatening asthma, hypercapnic decompensation, severe pneumonia, exhaustion or impending respiratory arrest.
Concept 2
Prescribe oxygen to target, treat bronchospasm and infection, support ventilation and plan prevention and rehabilitation.
Exam cue: Use peak flow or spirometry when safe, blood gases, microbiology and imaging according to acute severity.
Risk pitfalls and guardrails
Being reassured by a quiet chest or relying on oxygen saturation to assess ventilation.
Guardrail: Do not select an option merely because it is true; choose the one that best fits the exact clinical task, urgency and time point.
Selecting an option that is true in isolation but does not best answer the exact clinical task.
Guardrail: Do not interpret a visual pattern without the modality, clinical context and the exact task in the stem.

Being reassured by a quiet chest or relying on oxygen saturation to assess ventilation.
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 28-year-old woman with asthma is unable to complete sentences, respiratory rate 34/min and peak flow 28% predicted. What is the immediate treatment?
A patient with asthma becomes quiet and drowsy. PaCO2 is normal despite severe distress. Why is this concerning?
Answer all questions to submit.
