Emergency Care for Adults — 24 Hours a Day

Adult emergency care at Montrose Emergency Room is immediate medical evaluation and treatment for adults with serious, sudden or rapidly worsening symptoms. Our ER is open 24/7, staffed by an emergency physician, and equipped with on-site imaging and laboratory testing so many conditions can be assessed and treated in one visit.

Some health problems can safely wait for a primary care appointment, while others need emergency-level evaluation. When symptoms are severe, come on suddenly, or get worse quickly, an emergency room is designed to evaluate and stabilize them and has broader diagnostic and treatment capabilities than a typical clinic. Montrose Emergency Room serves adults of all ages, including seniors, and welcomes walk-ins without an appointment.

Know the Warning Signs

Adult Symptoms That May Require Emergency Evaluation

The right level of care depends on how severe your symptoms are, how quickly they started and your overall health. The following symptoms are commonly evaluated in the emergency room. This list is educational and does not replace an individual medical evaluation.

Chest pain or pressure, especially with sweating, nausea or arm/jaw pain
Difficulty breathing or severe shortness of breath
Severe abdominal pain, sudden or worsening
Sudden severe headache unlike any before
Weakness or numbness, especially on one side
Stroke warning signs — face drooping, arm weakness, speech difficulty
Fainting or loss of consciousness
Severe or sudden dizziness
Signs of dehydration with vomiting or weakness
Persistent vomiting or inability to keep fluids down
High or persistent fever with worsening illness
Signs of serious infection
Severe allergic reaction
Possible broken bones or deformity
Deep or severe cuts and wounds
Urinary or kidney symptoms with severe pain or fever
Significant injuries from falls or accidents
Uncontrolled bleeding

If any symptom appears life-threatening — severe chest pain, major difficulty breathing, stroke signs, uncontrolled bleeding or loss of consciousness — call 911 immediately.

When Should an Adult Go to the ER?

An adult should go to the emergency room for symptoms that are severe, come on suddenly, or worsen quickly — such as chest pain, serious difficulty breathing, stroke warning signs, severe abdominal pain, uncontrolled bleeding, major injuries, fainting or a sudden severe headache. When symptoms may be life-threatening, call 911 rather than driving.

For milder, non-urgent problems — minor colds, small cuts or uncomplicated illnesses — an urgent care or primary care visit is often appropriate. When you are unsure and symptoms are significant, the safer choice is emergency evaluation. Montrose Emergency Room is open 24/7 for adults who need to be seen right away.

Choosing the Right Care

Adult ER vs. Urgent Care

Urgent care is generally intended for mild, non-life-threatening illnesses and injuries. An emergency room is designed for serious, severe or rapidly worsening symptoms and has broader emergency diagnostic and treatment capabilities. Capabilities vary by facility.

Choose the ER for

Chest pain or pressure
Serious difficulty breathing
Stroke warning signs
Severe abdominal pain
Major injuries or fractures
Uncontrolled bleeding
Fainting or confusion
Severe allergic reactions
Severe dehydration

Urgent care may fit for

Minor cold or flu symptoms
Minor cuts and scrapes
Mild sprains
Low-grade fever in an otherwise well adult
Uncomplicated rashes
Routine minor illnesses

If symptoms appear life-threatening, call 911. Read our full ER vs Urgent Care guide.

What to Expect

What Happens When You Arrive?

Check-In

Walk in without an appointment. Our team gathers your basic information and the reason for your visit.

Medical Evaluation

An emergency provider reviews your symptoms, history and current condition to guide next steps.

Diagnostic Testing

When appropriate, testing may include labs, EKG, X-ray, CT or ultrasound performed on site.

Treatment & Next Steps

Treatment is based on the findings and may include medication, IV fluids, monitoring or coordination of a higher level of care.

On-Site Diagnostics

On-Site Diagnostic Capabilities

When testing is medically appropriate, having imaging and laboratory services inside the emergency facility helps the care team evaluate your condition without sending you to a separate outpatient center.

CT Scan

CT imaging may help evaluate certain head, chest and abdominal emergencies when ordered by the physician.

Digital X-Ray

X-rays help assess possible fractures, certain chest conditions and other injuries.

Ultrasound

Ultrasound may be used for selected abdominal, pelvic and other evaluations when clinically appropriate.

On-Site Laboratory

Lab testing supports evaluation of infection, dehydration, cardiac concerns and other conditions.

EKG & Cardiac Testing

An EKG and related testing may be used for chest pain, palpitations or other heart-related symptoms.

Testing is selected based on your symptoms, examination and the physician's assessment.

Emergency Treatment

Emergency Treatment for Adults

Treatment depends on your evaluation and the results of any testing. Depending on the condition, emergency care may include appropriate medications, IV fluids, wound care, splinting or immobilization, breathing treatments, cardiac monitoring or other interventions. The emergency team focuses on evaluating and stabilizing your condition and explaining the next steps in your care.

Next Level of Care

If Hospitalization or Specialty Care Is Needed

Some patients need admission to a hospital, surgery or care from a specialist that is beyond the scope of a freestanding emergency room. When that is the case, the emergency team can arrange transfer and coordinate the appropriate next level of care. Our goal is to evaluate and stabilize your condition and help you move to the right setting safely.
