EMS management

our agency has been contacted to participate in Career Day at the local high school. You have been told this is not the typical type of Career Day. For this event, you will need to develop a PowerPoint presentation to share the history and major milestones that have occurred in the field of emergency medical services (EMS) as well as a description of the clinical levels of emergency medical care today in order to show the high school students how much the EMS field has grown over the years.
You have been asked to provide the following historical descriptions:

how patients contacted EMS for service over the years,
what types of providers could be expected,
the level of care to be anticipated,
how patients were transported to the hospital emergency department, and
major milestones that have occurred in the field of EMS.

Following this, you will provide the high school students with a description of the four levels of care in EMS today, and you will describe how they have improved patient outcomes. In addition, describe how the improvement in patient outcomes is used by administrators and providers within EMS to plan and develop their agencies.
Consider how you would describe the information in layman’s terms.
Your presentation should consist of at least eight slides, not counting the title and reference slides.
Use two foundational resources to support your presentation. Resources that you may find useful can be found in the references section of the Unit I Lesson. Adhere to APA Style when creating ciations and references for this assignment. APA formatting, however, is not necessary.  EMS must be written out as emergency medical service .
