The PICU Essentials app was designed as a practical handbook for rotating residents, advanced practice providers and fellows. It is based on 20 years of PICU practices. While much of the content describes practices or protocols at UF Health Shands Children’s Hospital, it could be applied in most settings. The app is provided free of charge thanks to the Children’s Miracle Network and the UF Department of Pediatrics. For questions regarding the app please contact Charlene Pringle firstname.lastname@example.org.
