The ED provides emergency services via a three-bed unit. Care in the ED is provided by the best physicians, emergency nurse practitioners (ENPs), registered nurses, and EMT/ED techs in the region. The ED team is supported by a 24-hour on-call lab and radiology staff.

The ED maintains 24-hour emergency services that meet the needs of acutely-ill patients of all ages, including:

  • Patient assessment and treatment directed by physician’s orders, as well as hospital and departmental policies
  • Patient education and discharge planning
  • Therapeutic and diagnostic procedures
  • Medication administration
  • Transfer, if necessary, to the appropriate tertiary care center
  • Stabilization

Each patient is individually evaluated for a plan of care by a physician or ENP specializing in emergency medicine.
