Topic module

Breathlessness and Respiratory Disease

Assess acute breathlessness, asthma, COPD, pneumonia, pleural disease and respiratory failure using physiology and severity.

Long-form learning

Concept to Risk to Memory to Check-up

Practise recognising the immediate clinical task, ruling in or out dangerous alternatives, choosing the safest next step and closing the loop.

Core concepts

Concept 1

Oxygen is a treatment prescribed to a target range while the cause of hypoxaemia is addressed.

Exam cue: Use ABCDE, target oxygen and early escalation while refining the cause.

Concept 2

Severe asthma or COPD is recognised through physiology, exhaustion and response, not wheeze intensity alone.

Exam cue: Interpret blood gases in clinical context.

Risk pitfalls and guardrails

Being reassured by a quiet chest in severe asthma.

Guardrail: Avoid an option that names a plausible diagnosis but ignores physiology, contraindications, competence, patient priorities or follow-up.

Giving oxygen without a target or reassessment.

Guardrail: Avoid an option that names a plausible diagnosis but ignores physiology, contraindications, competence, patient priorities or follow-up.

Memory anchors

What frames acute breathlessness?

Airway, work of breathing, oxygenation, circulation, onset and immediate reversible threats.

What makes asthma life-threatening?

Severe physiological compromise, exhaustion, altered consciousness or poor respiratory effort.

How is oxygen prescribed?

State target saturation, delivery device, flow or concentration and monitoring.

What does a blood gas answer?

Ventilation, oxygenation and acid-base status when interpreted with the patient and treatment.

What supports chronic respiratory care?

Smoking support, inhaler technique, vaccinations, rehabilitation, exacerbation plan and review.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Knowledge Check (after reading)

Short check-up to confirm understanding of this module.

1-2 question checkpoint

A patient with asthma has a silent chest, exhaustion and oxygen saturation 86%. What is best?

A patient with acute severe asthma is hypoxic. What treatments are central?

Answer all questions to submit.
