How fast
Within 30 minutes
Sooner if anything on the go-now list applies.
Go now if
- Systolic under 90 mmHg, or more than 40 below their usual
- HR over 130, cold peripheries, confusion
- Bleeding, or suspected sepsis
Ask on the phone
- BP now and their usual BP; manual reading?
- Heart rate, temperature, urine output.
- Any bleeding, drains, melaena? New drugs (antihypertensives, opioids)?
Every bleep: the basics
- Name, ward, bed, age, why they're in hospital.
- Full set of obs and the NEWS2 score — and what it was before.
- Resuscitation status (DNACPR / ReSPECT) and ceiling of care.
Ask the nurse to start
- Lie flat and raise the legs; manual BP.
- IV access, capillary glucose, ECG; hold antihypertensives.
- If sepsis is suspected, start the sepsis screen.
Call your senior if
- Systolic under 90 not responding to a first fluid bolus, lactate over 4, or any sign of shock.
When you get there
For healthcare professionals, as an aid to clinical judgement — not a substitute for it. Follow your local policy and ask a senior when in doubt.
