The Resuscitation Council UK (RCUK) has published updated Basic Life Support (BLS) and Advanced Life Support (ALS) guidelines, marking the most significant revision to UK resuscitation practice since the European Resuscitation Council's 2021 guidelines were adopted. The updated guidance reflects new evidence from large-scale resuscitation research programmes and introduces several changes that first aid trainers and healthcare professionals need to be aware of.

Key Changes to Basic Life Support

The most significant change in the updated BLS guidelines concerns the management of witnessed cardiac arrest in public settings. The RCUK now recommends that bystanders who witness a cardiac arrest should immediately call 999 and begin chest compressions without waiting for dispatcher instructions, reversing previous guidance that emphasised dispatcher-assisted CPR as the primary pathway.

Other notable changes include:

  • Compression depth guidance has been refined to 5–6cm for adults, with clearer guidance on avoiding over-compression beyond 6cm
  • The recommended compression rate remains 100–120 per minute, but the guidance now emphasises the importance of full chest recoil between compressions
  • Mouth-to-mouth ventilation is now recommended for all trained rescuers, with compression-only CPR reserved for untrained bystanders or situations where ventilation is not possible
  • New guidance on CPR in obese patients, including modified hand positioning and the potential need for higher compression forces

Changes to AED Use

The updated guidelines introduce clearer guidance on the use of automated external defibrillators (AEDs) in public settings. The RCUK now recommends that AED pads should be applied as soon as the device is available, even if CPR is ongoing, and that CPR should continue while the AED analyses the rhythm wherever possible.

Implications for First Aid Trainers

First aid trainers will need to update their training materials and delivery to reflect the new guidelines. The RCUK recommends that all training organisations update their programmes within six months of the guideline publication date.

Trainers seeking to ensure their qualifications are current should consider refresher training through an accredited provider. Abertay Training offers First Aid Trainer courses that are updated to reflect the latest RCUK guidelines, with details also available at FirstAidTrainer.com.
