Each of these modules is meant to cover the basics of a broad range of core critical care topics. Learning objectives for the module will be presented during the first segment and covered over the course of the subsequent parts. There will be occasional practice questions and worked examples to reinforce some of the most important concepts - try your best to pause the video, work through, and follow along each of these. Some sections might leave you with more questions than answers, and that is okay - bring those questions with you to the bedside in order to have more in-depth discussions with your ICU attending. We hope to continue adding modules over time, but hopefully this is enough of a foundation for which to have a fruitful learning experience in the ICU.
