This app was designed to be used as a practical handbook for rotating residents, advanced practice providers, and fellows. It is based upon 20 years of PICU practice, and while much of the content describes practice or protocols here at UFHealth/Shands Children’s Hospital, it could be applied in most settings. This app is now in use in over 50 countries. All content is peer-reviewed, and content is reviewed for currency every 1-2 years and as needed. All proceeds from this app go toward maintaining and developing the app itself.
