When do I call for an ambulance?
Is the victim’s condition life-threatening or could it worsen and become life threatening on the way to the hospital? Could moving the victim cause further injury? Does the victim need the skills or equipment of emergency medical technicians? Would distance or traffic conditions cause a delay in getting the victim to the hospital?
If the answer to any of these questions is “yes,” or if you are unsure, it’s best to call an ambulance. EMTs are trained to begin medical treatment on the way to the hospital and can alert the doctors of the patient’s condition in advance.

Example warning signs:
Severe burns, bleeding that won’t stop, severe or persistent vomiting, coughing up or vomiting blood, suicidal or homicidal feelings, difficulty breathing, chest or upper abdominal pain or pressure, fainting or sudden collapse, sudden dizziness, weakness or change in vision, change in mental status.
