How to read this visual
- Read across the columns for the phases of the pathway; the swimlanes are who acts — Emergency team, Monitoring and IV access, Critical care and specialist input.
- Bold marks the dose, threshold or time limit that decides the next step; the rest of a label is context.
- Treat airway, breathing or circulation problems as anaphylaxis when the clinical context supports it.
- Open node notes for repeat treatment, refractory symptoms and observation qualifications.
Clinical notes
- Do not delay intramuscular adrenaline for antihistamines or corticosteroids.
- Use local paediatric, obstetric and peri-operative pathways where those populations or contexts apply.
