Emergency Medical Services (EMS), commonly known as the ambulance service, provides urgent pre-hospital treatment and stabilization for sudden illness or injury. This coordinated system includes trained professionals, specialized vehicles, and communication centers that bridge the gap between a medical crisis and definitive hospital care. Knowing how to engage this system effectively during a crisis is paramount, as the emergency call requires rapid, clear communication to ensure a swift response. The dispatcher’s ability to send the correct resources depends entirely on the accuracy and speed of the information you provide.
Deciding When Emergency Services Are Needed
The decision to call an ambulance should be reserved for situations where a person’s condition is life-threatening or could rapidly worsen during self-transport. Emergency transport is necessary when the patient requires the specialized skills, equipment, and medical intervention that only paramedics and Emergency Medical Technicians (EMTs) can provide on the scene and en route to the hospital. Conditions posing a risk of serious impairment to bodily functions warrant an immediate emergency call.
Clear, urgent examples include sudden, severe chest pain (indicating a heart attack) or symptoms of a stroke, often remembered by the acronym F.A.S.T. (Facial droop, Arm weakness, Speech difficulty, Time to call). Other situations demanding an ambulance are uncontrollable bleeding, sudden difficulty breathing, or the loss of consciousness. Attempting to move a patient with a suspected spinal or neck trauma, or severe second or third-degree burns, can cause further harm, making professional medical transport the only safe option.
The Steps for Initiating the Call
When an emergency occurs, locate the appropriate emergency number for your region, such as 911 in the United States or 112 across much of Europe. Dial this number immediately and try to remain composed. Dispatchers are trained to guide callers through the process, but a clear voice helps them process information quickly.
The most important instruction is to stay on the line until the dispatcher explicitly tells you it is acceptable to hang up. Even after services have been dispatched, the call-taker may provide crucial pre-arrival instructions, such as guidance on performing chest compressions or controlling severe bleeding. Following these instructions can provide life-saving treatment during the minutes before first responders arrive on the scene.
Essential Information to Give the Dispatcher
The conversation with the dispatcher follows a structured protocol designed to ensure the fastest and most appropriate response.
Location and Contact
The first information you must provide is your exact location. This should include the full street address, cross streets, apartment number, floor, or any distinguishing landmarks, as cell phone location tracking is not always perfectly precise. You must also clearly state the phone number you are calling from, which is necessary in case the call is disconnected.
Nature of the Emergency
Next, describe the nature of the emergency in a brief, accurate manner, such as “a car accident with injuries” or “an unconscious person.” This concise description helps the dispatcher determine the type of emergency service needed (medical, fire, or law enforcement).
Patient Details
The dispatcher will then ask specific questions about the patient or victims, including the number of people affected and their apparent condition. Be prepared to state the patient’s age, whether they are conscious, and if they are breathing normally. These detailed questions allow the dispatcher to categorize the severity of the incident and send the correct level of care, such as an Advanced Life Support (ALS) or Basic Life Support (BLS) unit. Answer every question clearly, even if the information seems repeated, because the dispatcher is simultaneously entering data while emergency resources are being sent.
Preparing for the Arrival of EMS
Once the call is complete, several actions can ensure a rapid and seamless transition of care while waiting for the ambulance.
Ensuring Access
If you are inside a residence, unlock the front door or have someone meet the responders outside to guide them to the exact location. This saves valuable time, as first responders will not have to search for the correct entry point. If the emergency occurs at night, turn on exterior lights, such as porch lights, to make the location more visible from the street.
Securing the Scene
It is also important to secure any household pets in a separate room or outside area to prevent them from interfering with the responders or potentially escaping.
Gathering Medical Information
While waiting, gather medical information helpful to the paramedics upon their arrival. This includes a current list of the patient’s medications, known allergies, and any significant medical history. Having this data ready can immediately inform the paramedics’ treatment decisions and accelerate care.
