When to Go to the ER in Five Minutes
When to Go to the ER: the whole thing in five minutes, for when you want the numbers and nothing else.
The hospital emergency room (emergency department), open around the clock for serious injury and illness.
Key takeaways
- What it is for: chest pain, trouble breathing, heavy bleeding, loss of consciousness, signs of stroke, severe injury
- Order of treatment: by medical need (triage), not by arrival time
- Most useful single change: Call 911 rather than driving yourself if someone may be having a heart attack or stroke.
- Commonest mistake: Going for prescription refills, work notes or long-standing problems.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The numbers, in one place
| Measure | Figure |
|---|---|
| What it is for | chest pain, trouble breathing, heavy bleeding, loss of consciousness, signs of stroke, severe injury |
| Order of treatment | by medical need (triage), not by arrival time |
| Your rights | ERs must screen and stabilize anyone with an emergency, regardless of ability to pay |

| Alternatives | your doctor's office, a nurse line, telehealth, urgent care or a pharmacist |
In one paragraph
It is the right place for emergencies and usually the slowest and most expensive place for everything else.
Worth doing
- Call 911 rather than driving yourself if someone may be having a heart attack or stroke
- For urgent problems that are not life-threatening, call your doctor's office or nurse line first
- Take a list of your medicines, or the bottles themselves, and your insurance card
- Tell the triage nurse clearly what the worst symptom is, not the whole history
Worth avoiding
- Going for prescription refills, work notes or long-standing problems
- Driving yourself if you feel faint or have chest pain
- Eating or drinking before you have been assessed, in case you need surgery

When to speak to a doctor
Call 911 immediately for chest pain or pressure, sudden weakness or drooping on one side, difficulty speaking, severe breathlessness, heavy bleeding that will not stop, or someone who is unresponsive. Do not wait to see whether it passes. Follow up with your own doctor after any ER visit.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarized or generalized beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
