New Resuscitation Guidelines Set to Transform First Aid in UK & Ireland

Both the Resuscitation Council UK (RCUK) and the European Resuscitation Council (ERC) have released their comprehensive 2025 Resuscitation Guidelines, with implementation rolling out across the UK and Ireland throughout 2026. These updates, developed through extensive scientific review and collaboration, aim to improve survival rates from cardiac arrest and strengthen emergency care systems. The new guidelines will affect healthcare professionals, first aid trainers, and the general public, emphasising earlier intervention and streamlined communication with emergency services.

The RCUK guidelines are informed by the International Liaison Committee on Resuscitation (ILCOR) 2025 Consensus on Science with Treatment Recommendations and the ERC Guidelines for Resuscitation 2025, ensuring a consistent, evidence-based approach.

Key Changes in Adult Basic Life Support

One of the most significant changes in the 2025 guidelines for adult basic life support (BLS) is the updated instruction for contacting emergency services. Rescuers are now advised to call 999 immediately upon finding an unresponsive person, *before* assessing breathing. Ambulance call handlers will then guide the caller through the breathing assessment and provide instructions for cardiopulmonary resuscitation (CPR) if needed. This simplified flow aims to reduce hesitation and initiate the emergency response more quickly.

The fundamental adult CPR ratio of 30 chest compressions to 2 rescue breaths remains unchanged. Chest compressions should be delivered at a rate of 100-120 per minute to a depth of 5-6 cm, with minimal interruptions. For untrained bystanders, call handlers will provide guidance on chest-compression-only CPR.

Regarding automated external defibrillator (AED) use, the guidelines reinforce that anyone can use an AED, and clear signage should indicate that no prior training is required. AED locations should be widely advertised and registered with The Circuit. If multiple rescuers are present, CPR should continue while AED pads are being attached.

Updates in Paediatric Resuscitation and First Aid

The 2025 guidelines introduce important updates for paediatric resuscitation, aiming to simplify techniques and improve outcomes for children and infants.

  • Age Definitions: New age definitions have been introduced: Baby/Infant (0-1 year), Child (1-12 years), and Adolescent (13-18 years).
  • Initial Rescue Breaths: For anyone under 18, CPR should begin with five initial rescue breaths, recognising that hypoxia is often the cause of cardiac arrest in children. This is particularly emphasised for drowning incidents, where five initial rescue breaths are now standard first aid guidance.
  • CPR Ratio: While the 30:2 ratio remains for adults, a 15:2 ratio is now recommended for children and babies, particularly for those who have attended dedicated paediatric training. However, if not specifically trained in paediatric resuscitation, the 30:2 ratio for everyone is acceptable and will be guided by emergency call handlers.
  • Infant CPR Hand Positioning: The two-thumb encircling technique is now the sole recommended method for infant chest compressions, replacing the previous two-finger guidance. This is believed to provide more consistent pressure.
  • Choking in Infants: Chest thrusts for a choking infant now utilise the same two-thumb encircling grip as infant CPR, simplifying the technique.
  • Calling Emergency Services for Children: For unresponsive children, the guidance now advises calling 999 *first*, before giving rescue breaths, a change from previous recommendations.
  • AED Pad Placement: For infants and children, pads should be placed front and back (one on the chest centre, one on the back between the shoulder blades). For adolescents, standard adult pad placement applies.

Broader Implications and Ethical Considerations

Beyond specific CPR techniques, the new guidelines place a stronger emphasis on a 'Systems Saving Lives' approach, advocating for better coordination between education, community response, emergency services, and hospitals to strengthen the chain of survival. This includes recommendations for mandatory CPR training for schoolchildren, students, and drivers, with annual training starting from age four, utilising engaging methods such as gamified learning and simulations.

Ethical considerations are also given greater prominence. The 2025 guidance promotes early, person-centred conversations about emergency and future care, supported by clear documentation such as ReSPECT (Recommended Summary Plan for Emergency Care and Treatment) forms. These forms are becoming increasingly accessible across the NHS, with full rollout across Northern Ireland expected in 2026. The guidelines also highlight the option for families to be present during resuscitation attempts, with appropriate support, and encourage ethical training for healthcare professionals.

The Resuscitation Council UK encourages all organisations to begin preparing for the implementation of these new guidelines throughout 2026, with updated training materials and manuals becoming available from January 2026. It is crucial for all those involved in first aid and emergency care to familiarise themselves with these updates to ensure best practice.
