So I will try my best to answer your question as there is not much substance to to the question itself.

If you looking for the latest European guidelines for CPR (Cardiopulmonary resuscitation) you can find it at: https://www.cprguidelines.eu/

If you are looking for ACLS algorithms it would be: https://cpr.heart.org/en/resuscitation-science/cpr-and-ecc-guidelines/algorithms

There are probably other guidelines available however these should serve nicely as a guideline.
