From DR ABC to DR C ABCDE - What First Aiders Need to Know

Resuscitation guidance is regularly reviewed to reflect the latest evidence, research, and real-world experience. This in turn reflects how we respond to emergencies as First Aiders. The Resuscitation Council UK 2025 guidelines build on existing good practice, refining how we respond in those critical first moments to help save more lives.

As First Aiders, our training has been adjusted to align with the latest RCUK updates. Importantly, these updates don’t mean previous guidance was wrong. Instead, they focus on building on existing good practice to help us respond earlier, faster, and more effectively when it matters most.

What Has Changed?

One of the biggest updates is the move from:

DR ABC → DR C ABCDE

This change reflects three key priorities:

Earlier activation of emergency services
Immediate control of catastrophic bleeding
A more complete assessment of the casualty

The New Primary Survey: DR C ABCDE

Here’s how the updated approach works in practice:

• D – Danger

Ensure the scene is safe for you, the casualty, and others
Look for hazards before approaching

• R – Response

Check responsiveness using the ACVPU scale (Alert, Confused, Voice, Pain, Unresponsive)
If unresponsive, call 999/112 immediately (112 is the EU wide emergency number)
Ask a bystander to call if possible
Put the phone on speaker (or ask the bystander to do this) to receive instructions while you help

• C – Catastrophic Bleeding (NEW PRIORITY)

Check for severe, life-threatening bleeding straight away
Signs of life-threatening bleeding: spurting, pouring or heavy uncontrolled bleeding.
Act immediately:
- Apply direct pressure
- Use a tourniquet if trained

👉 This is a major shift: bleeding control now comes before airway and breathing

• A – Airway

Open and maintain a clear airway
For casualties over the age of one year, use the head-tilt, chin-lift method. Place one hand on the forehead and two fingers on the tip of the chin. Gently tilt the head back to open the airway. Ensure the airway is open while checking for breathing.

• B – Breathing

Check for normal breathing (no more than 10 seconds)
If not breathing normally, start CPR immediately

• C – Circulation

If the casualty is breathing look for:
- Signs of shock (pale, cold, clammy, breathing fast, confusion)
- Ongoing bleeding
Treat as needed
If there is no sign of spinal injury/major trauma the casualty can be placed in the recovery position to protect the airway. If there are signs of shock present, lay the casualty flat and raise the legs

• D – Disability (NEW)

Assess for neurological issues, including:

Confusion or unusual behaviour
Slurred speech
Unequal pupils
Weakness or numbness (especially on one side)
Seizures
Signs of stroke or head injury

• E – Exposure (NEW)

Check for hidden injuries
Look for:
- Burns, rashes, swelling
- Medical alert jewellery
Prevent heat loss:
- Keep the casualty warm after checks

Early 999 Call: A Key Change

Another critical update is when to call for help.

Previously:

Call after checking breathing

Now:

Call as soon as the casualty is unresponsive

You should:

Call before checking breathing
Check breathing while on the phone on loudspeaker
Follow instructions from the call handler

👉 This ensures help is on the way as early as possible, without delaying care

Using Call Handler Support

First aiders are now actively encouraged to:

Put phones on speaker mode
Follow real-time guidance from emergency call handlers
Begin treatment while receiving support

This can make a huge difference, especially for less experienced first aiders.

Why This Update Matters

These changes are based on evidence showing that:

Delays cost lives
Severe bleeding needs immediate control
Early emergency activation improves outcomes
Structured assessment reduces missed injuries

By updating the primary survey, the Resuscitation Council UK is helping first aiders:

Act faster
Prioritise life-threatening conditions correctly
Feel more confident in high-pressure situations

What This Means for First Aid Training

If you attend first aid courses, you’ll start to see:

DR C ABCDE replacing DR ABC in manuals and teaching
Greater emphasis on bleeding control skills
Stronger focus on early emergency calls
Inclusion of Disability and Exposure assessments

Final Thoughts

The move to DR C ABCDE is a practical, evidence-based evolution of first aid practice. It keeps what worked well but improves how we respond in those first crucial minutes.

For first aiders, the message is simple:
