PN System Pathways

Choose a system and follow the tutorials in order. Each pathway is built for perfusion-first clinical reasoning with NGN decision practice.

How to use this page

  • Start with the system you are struggling with most.
  • Finish the pathway in order to build clinical judgment.
  • Track weak cells + cues and revisit them weekly.
