Just the information you need, organized for quick access and the way you think. HONEST ABOUT WHAT THIS IS Rapid Reference is a reference and education tool designed for health care professionals working in critical care in the ICU. It is not medical advice, not a diagnostic device, and not a replacement for your institution's policies, procedures, the laws and regulations of your licensing governing body, or the orders of a qualified prescribing provider.
