The 2025 Resuscitation Council UK guidelines represent an important update to how we approach Basic Life Support (BLS) — ensuring UK first aiders and bystanders are even better equipped to act in a cardiac emergency. These changes emphasise simpler, faster action, better support, and stronger community response.
🔹 Call 999 First, Then Assess
If you find someone unresponsive, you should now call 999 immediately before checking for normal breathing — reducing hesitation and speeding up help. Ambulance call handlers can guide you through recognising cardiac arrest and starting CPR.
🔹 Focus on Early, High-Quality CPR
Chest compressions remain at the heart of BLS: aim for 100–120 compressions per minute, to a depth of 5–6 cm, with minimal interruptions. Rescue breaths are encouraged if you’re trained — otherwise, compression-only CPR will be guided by emergency dispatch.
🔹 Defibrillator Use for All
Automated External Defibrillators (AEDs) should be accessible and used by anyone — they can significantly improve survival chances. Clear AED signage and 24/7 access are now strongly recommended.
🔹 Community & System Support
The updated guidance highlights the vital role of ambulance call handlers, first responders, and community AED networks in saving lives. There’s also recognition of the emotional impact on lay rescuers, with recommendations for support after a resuscitation event.
💡 Bottom Line:
These 2025 changes focus on reducing delays, empowering all rescuers, and strengthening community response to cardiac arrest. CPR fundamentals haven’t changed — but now it’s easier than ever for anyone to step in and make a difference.
