HeartCode® ACLS Part 1 is an online self-paced instructional program that uses eSimulation technology to allow students to assess and treat patients in virtual healthcare settings. In this environment, students apply their knowledge to real-time decision making and skills development. Debriefings and coaching are provided immediately after each simulation to facilitate learning. After completing the cognitive portion of the course (www.OnlineAHA.org), students must practice and test their skills with an AHA Instructor or on a voice-assisted manikin (VAM) system for full course completion Unprepared or inexperienced students may require additional time to complete HeartCode ACLS Part 1. To be successful in any ACLS course, students should be able to identify ECG rhythms and should know pharmacology specific to cardiopulmonary arrest and other cardiopulmonary emergencies before beginning the course. It is strongly recommended that students review the ACLS course materials contained within the program and complete the Precourse Self-Assessment prior to attempting the patient cases.
