Considerable evidence has been published since the 2020 Korean Cardiopulmonary Resuscitation Guidelines were reported.
The International Liaison Committee on Resuscitation (ILCOR) also publishes the Consensus on CPR and Emergency
Cardiovascular Care Science with Treatment Recommendations (CoSTR) summary annually. This review provides expert
opinions by reviewing the recent evidence on CPR and ILCOR treatment recommendations. The authors reviewed the
CoSTR summary published by ILCOR in 2021 and 2022. PICO (population, intervention, comparator, outcome) questions for
each topic were reviewed using a systemic or scoping review methodology. Two experts were appointed for each question
and reviewed the topic independently. Topics suggested by the reviewers for revision or additional description of the guide lines were discussed at a consensus conference. Forty-three questions were reviewed, including 15 on basic life support,
seven on advanced life support, two on pediatric life support, 11 on neonatal life support, six on education and teams, one on
first aid, and one related to coronavirus disease 2019 (COVID-19). Finally, the current Korean CPR Guideline was maintained
for 28 questions, and expert opinions were suggested for 15 questions
