The 2015 advanced life support guidelines: a summary and evidence for the updates

The International Liaison Committee on Resuscitation recently released updated 2015 recommendations for resuscitation. The guidelines form the basis for all levels of resuscitation training, now from first aid to advanced life support (ALS), and for trainees of varying medical skills, from schoolchildren to medical students and consultants. We highlight major updates relating to intra-arrest and postarrest care, and the evidence for their recommendation. We also summarise areas of uncertainty in the evidence for ALS, and highlight current discussions that will likely inform the next round of recommendations.
