Emergency Department

The Emergency Department at Mammoth Hospital is open 24-hours; seven days a week for anyone needing immediate medical attention. We welcome walk-in visits; no appointment is needed.

Our modern facility is supported by

  • first-rate equipment
  • a seven-bed triage area
  • a decontamination room
  • a two-bay trauma resuscitation suite
  • nine private examination rooms

Our specially-trained emergency staff are ready to provide acute medical care to visitors and residents alike. 

Adjacent to the Emergency Department is Mammoth Hospital’s Imaging Department with digital X-ray, fluoroscopy, diagnostic ultrasound, multi-detector CT scan, and MRI. Additional support is provided by the hospital’s Respiratory Department, in-patient Pharmacy, and Laboratory with blood bank. 

Emergency patients needing further care can be admitted to the Med/Surg unit, ICU, Labor & Delivery ward, or operating room. Should any patient’s medical needs exceed the resources of Mammoth Hospital, we will arrange for transport to a larger medical center.
