CRRT Family Education PICU

We are currently trying to develop some sort of handout/notebook to provide the families of the CRRT patients we care for a basic understanding of the purpose of CRRT, the method, what to expect and why the nurses all come RUNNING when the machine alarms! I hate to re-invent the wheel so if anyone has any feedback I would love to hear from you!
Thank you in advance for your help.... and if nothing else I will hopefully have some educational material SOON for these families.
