About Emergency Medical Services

If you get very sick or badly hurt and need help right away, you should use emergency medical services. These services use specially trained people and specially equipped facilities.

You may need care in the hospital emergency room (ER). Doctors and nurses there treat emergencies, such as heart attacks and injuries. For some emergencies, you need help where you are. Emergency medical technicians, or EMTs, do specific rescue jobs. They answer emergency calls and give basic medical care. Some EMTs are paramedics - they have training to do medical procedures on site. They usually take you to the ER for more care.

If you or someone you know needs emergency care, go to your hospital's emergency room. If you think the problem is life-threatening, call 911.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Emergency Medical Services

459 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
