About This Site

Welcome to the Arizona Critical Care Hub!

This website serves to provide Housestaff an online ICU Handbook. Every topic in Critical Care is met with a quick run-down of the disease process, but then will take you the literature behind the topic at hand. We highly encourage trainees to ensure that they familiarize themselves with the Guidelines and salient literature behind these complex processes. This website is dynamic in that when new Guidelines come out, they are updated on the site. There is also section geared for Pulmonary/Critical Fellows with ACGME Requirements, Procedure Training Videos from ATS, Fleischner Society Thoracic Imaging Review and Lung Pathology for the Boards.
