Cottage uses the Essentials of Critical Care Orientation (ECCO) produced by the American Association of Critical Care Nurses as a resource and as support for our critical care training program. ECCO is a computer-based program that allows you to independently learn the material required to become a critical care nurse. You can proceed at your own speed, repeat courses as many times as needed, and review the course material for up to one year. Your independent learning is augmented by bi-weekly meetings with an expert critical care nurse.
