Symptoms that should make you call 911 right now
Not sure whether to drive to a freestanding ER or call 911? If you see any of the signs below, call 911 immediately. Don’t try to drive.
Clear, time‑sensitive warning signs
- Severe chest pain, pressure, or squeezing that lasts more than a few minutes or comes and goes.
- Sudden severe shortness of breath or trouble breathing that makes it hard to speak in full sentences.
- Any sudden loss of consciousness or a fainting spell that you cannot wake from easily.
- Major trauma, such as a head injury, a broken bone protruding through skin, or high‑speed car crash.
- Uncontrolled, heavy bleeding that soaks through bandages quickly or is spurting blood from an artery.
- Signs of stroke using BEFAST: sudden loss of Balance, blurred or lost Eyesight, Facial droop, Arm weakness, Speech trouble, and note the Time symptoms started.
- Any rapid neurological change like severe confusion, sudden weakness, or trouble speaking.
- No pulse, collapse, or obvious cardiac arrest. Every minute without CPR or defibrillation greatly lowers survival odds.
Why EMS matters for these cases
Calling 911 brings trained paramedics and equipment to you right away. They can give oxygen, start CPR, use a defibrillator, secure an airway, and give critical medications before you reach the hospital.
Those prehospital steps improve survival and reduce long‑term harm for heart attack, stroke, and major trauma. For example, every minute without CPR and defibrillation lowers survival by about 7% to 10%.
In Arlington, EMS response is designed for speed, with average response times around five and a half minutes. That quick response, plus hospital notification ahead of arrival, helps teams start definitive care faster.
When in doubt, call 911. It’s not only about transport. It’s about starting life‑saving care immediately.

When driving to PrimeCare is the faster, safer choice
Not sure whether to call 911 or drive to a freestanding ER? Drive to PrimeCare when a problem needs fast, hospital‑level testing but is not immediately life‑threatening.
According to the American College of Emergency Physicians, freestanding emergency centers offer on‑site CT, X‑ray, and full labs so clinicians can diagnose and treat quickly. At PrimeCare that means a board‑certified physician can order testing and start treatment without sending you to multiple locations.
Common reasons to drive here
- Moderate injuries like sprains or closed fractures when the patient is stable and does not need immediate ambulance care.
- Deep lacerations that likely need sutures or repair but are not causing heavy, uncontrolled bleeding.
- Suspected broken bones that are painful and swollen but where vital signs are stable and there is no bone protruding through skin.
- Severe abdominal pain that is constant or worsening but the patient is alert and has stable breathing and circulation.
- High fevers, persistent vomiting, or signs of infection that worry you but are not causing breathing problems or severe confusion.
- Urgent pediatric complaints such as high fever, dehydration, or painful limb injuries that need quick testing but are not life‑threatening.
How on‑site imaging, labs, and observation speed your care
On‑site CT and digital X‑ray let clinicians see internal injuries within minutes instead of hours. Research shows immediate imaging and labs compress the time to diagnosis and treatment for head trauma, suspected stroke, and abdominal emergencies.
Our full lab lets us run blood work while you wait, so doctors can quickly tell if infection, bleeding, or metabolic problems are present. A state‑certified 23‑hour observation unit provides short‑term monitoring when symptoms need watching but do not require full hospital admission.
That combination reduces trips between facilities and gets you definitive answers faster. If your situation matches the examples above, driving to a freestanding ER like PrimeCare usually shortens diagnosis and speeds treatment.

A 60‑Second decision checklist you can use now
Not sure whether to call 911 or drive to PrimeCare? Use this quick checklist to assess danger and act fast.
- Check breathing: Is the person breathing normally or struggling to breathe?
- Check circulation: Is there a pulse, or is bleeding heavy and persistent?
- Check consciousness: Are they awake, responsive, and oriented to person and place?
- Check severe bleeding: Is blood soaking through dressings or spurting from the wound?
- Check choking: Can they cough, speak, or breathe at all?
- Check stroke signs with BEFAST and note the time symptoms began.
Immediate first aid while you wait for help can save lives. Follow the actions below and call 911 if symptoms are life‑threatening.
- For severe bleeding, apply firm, continuous direct pressure to the wound. Red Cross bleeding control
- If someone is choking and cannot breathe, give up to five back blows, then abdominal thrusts. Red Cross choking guidance
- For suspected anaphylaxis, use an epinephrine auto‑injector immediately into the outer thigh. AAAI anaphylaxis guidance
- If the person becomes unresponsive, check for breathing and begin CPR if there is no normal breathing.
Do not self‑transport if the patient has altered mental status, unstable vital signs, uncontrolled bleeding, or any sign that could worsen in transit. In those cases call 911 so EMS can begin treatment and provide safe transport.
If the patient is stable, distance, traffic, and time of day matter. A nearby 24/7 freestanding ER can be faster for non‑life‑threatening issues when roads are clear.
For workplace injuries, take photos, note the time and witnesses, and get a medical evaluation for workers' compensation documentation. We offer workers' compensation evaluations and can help record what insurers need.
