Whether you're just stepping into your first cardiac arrest or you've been running them since the days of paddles, this one's for you. The 2025 resuscitation guidelines have landed after further collaboration between ILCOR, the ERC and the Resuscitation Council UK and in this episode we break down exactly what's new, what's stayed the same, and how it all fits into day-to-day practice.

Across the board the 2025 updates represent evolution, a steady refinement of evidence rather than wholesale change. Adult ALS remains rooted in early recognition, high-quality compressions and rapid defibrillation, but you'll notice sharper guidance around ventilation, pad positioning, and the sequence of vascular access and drugs. There's a new section on physiology-guided CPR and the emerging science behind arterial-line-driven resuscitation as we covered in the SPEAR epsiode.

We also take a look at the special circumstances algorithms from hypothermia to traumatic and obstetric arrest and discuss how an emphasis on reversible causes, data-driven debriefing and system performance might reshape post-event learning.

Paediatric and newborn life support see subtle but important refinements too, including pad placement, shock energy escalation, simplification of adrenaline timings and a new Out-of-Hospital Newborn Life Support algorithm aimed squarely at the pre-hospital world. All this and more in the episode!

Once again we'd love to hear any thoughts or feedback either on the website or via X @TheResusRoom!
