Both firefighting and EMS are in the business of doing a dangerous job safely. Not many other occupations put employees in austere environments with the job of saving a person’s life. In the aviation community, it was discovered that human error was the main cause of most aviation mishaps. Because of this, Crew Resource Management (CRM) was created and remains one of the pillars behind aviation safety. In this lecture, attendees will learn the fundamentals behind human error and how human errors occur. The focus will then shift to learning the guiding principles of CRM and how to implement them to reduce errors in patient care.
