🚑 BEYOND THE LIGHTS & SIRENS — PART 2
YOU CALLED 911. NOW WHAT?🤔
You dial 911. You hear, “911, what’s the address of your emergency?”
From that moment, a system starts moving—even while you’re still on the phone.
Most people only see the ambulance arrive. But what happens between “I need help” and our crew walking through the door involves dispatchers, EMS providers, sometimes multiple responding agencies, medical equipment, communication, and a lot of decision-making.
Here’s what’s happening behind the scenes.
📞 STEP 1: YOUR 911 CALL
One of the most important pieces of information you can give the 911 telecommunicator/dispatcher is your location.
Before EMS can help you, we have to find you.
The dispatcher will ask questions such as what happened, whether the patient is conscious and breathing, the patient’s approximate age, and whether there are any immediate dangers at the scene.
It can feel like a lot of questions during a stressful moment, but those questions have a purpose.
Answering them does not mean help is being delayed.
Information can be gathered and relayed to responders while resources are being dispatched. Depending on the emergency and local dispatch protocols, the telecommunicator/dispatcher may also provide instructions for things that can be done before responders arrive.
📻 STEP 2: THE CALL REACHES EMS
Once we're dispatched, the information available from the 911 call is passed along to our crew.
We may receive information such as:
“Chest pain.”
“Difficulty breathing.”
“Fall with injury.”
“Unresponsive patient.”
“Motor vehicle crash.”
That initial information gives us somewhere to start—but dispatch information isn't a diagnosis.
A call that sounds relatively minor can turn out to be life-threatening. A patient’s condition can also change between the time someone calls 911 and the time we arrive.
So while we're responding, we're already thinking ahead.
What could we be walking into? What equipment might we need first? What treatments might be necessary? Could additional resources be needed?
We don't wait until we're standing beside the patient to start preparing.
🚑 STEP 3: THE AMBULANCE RESPONDS
This is the part everyone recognizes: the ambulance heading toward the call.
Lights and sirens may be used when appropriate, but they aren't magic.
We still have to navigate traffic, intersections, weather, road conditions, construction, rural roads and other hazards safely.
If you see an emergency vehicle approaching with its emergency lights activated, please safely yield and give us room.
Those few moments matter.
And in rural EMS, location matters too. Our response area includes communities, highways, farms and rural properties—not just addresses a few blocks from an ambulance station.
🚨 STEP 4: WE ARRIVE—BUT WE DON'T AUTOMATICALLY RUN STRAIGHT IN
Before we can treat anyone, we have to be able to safely reach them.
EMS may encounter traffic, fire, downed power lines, hazardous materials, aggressive animals, violence, farm machinery or other hazards.
Depending on the call, law enforcement, fire departments or other resources may respond alongside us.
Once it's safe to approach, the medical assessment begins immediately.
We are figuring out how to get the patient from their location to the back of our ambulance safely and securely.
We're already looking at the patient as we walk toward them.
Are they awake?
Are they breathing normally?
What does their skin look like?
Can they speak normally?
Are they bleeding?
Are they sitting upright trying desperately to breathe—or walking around talking to us?
Sometimes those first few seconds tell us a lot.
🩺 STEP 5: NOW WE START PUTTING THE PUZZLE TOGETHER
This is where patients sometimes wonder:
“Why are you asking me so many questions?”
Because your answers matter.
We're gathering medical history, medications, allergies, symptoms, what happened before the emergency and when things changed.
At the same time, we may be checking blood pressure, pulse, respiratory rate, oxygen saturation, blood glucose, temperature or obtaining a 12-lead ECG.
We may perform a neurological assessment, examine an injury or listen to the patient's lungs.
We're combining what you tell us + what we see + what we find + what our equipment shows us.
That's how we begin determining what needs to happen next.
💊 STEP 6: TREATMENT CAN START RIGHT THERE
This is one of the biggest misconceptions about EMS:
We don't have to reach the hospital before medical care begins.
Depending on the patient's condition and the provider's level of care, treatment may include oxygen, airway management, ventilation, IV or IO access, medications, cardiac monitoring, 12-lead ECGs, defibrillation, pacing, bleeding control, splinting, CPR and other emergency interventions.
For a critically ill patient, several things may be happening at the same time.
One provider may be assessing the patient while another prepares equipment. Treatment may begin while we're gathering history. Additional resources may be requested while we're preparing to move the patient.
EMS is constantly prioritizing:
WHAT NEEDS TO HAPPEN FIRST?
🏥 STEP 7: WHERE SHOULD THE PATIENT GO?
Sometimes the answer is straightforward.
Sometimes it isn't.
The closest hospital isn't necessarily the right destination for every patient. Certain emergencies may require resources available only at particular facilities.
That means we may need to consider the patient's condition, severity, time, distance, available resources, protocols and hospital capabilities.
Getting a patient to the appropriate level of care is part of EMS.
This becomes especially important in rural Iowa, where specialized care may be a significant distance away.
🚑 STEP 8: CARE CONTINUES DURING TRANSPORT
Loading the patient into the ambulance doesn't mean our assessment is finished.
We're continually reassessing.
Did the medication help?
Is the oxygen level improving?
Has the blood pressure changed?
Is the patient's pain changing?
Has their mental status changed?
Is the heart rhythm different?
Do we need to change our treatment?
Meanwhile, we may communicate with the receiving hospital so its team can begin preparing before we arrive.
When we reach the hospital, we provide a report and transfer responsibility for the patient to the receiving healthcare team.
Only then is that portion of the EMS call complete.
🏠 YOU CAN HELP BEFORE WE ARRIVE
If you call 911, a few simple things can make a big difference when they're safe and practical:
🔹 Give dispatch the correct location and answer their questions as clearly as possible.
🔹 Turn on exterior lights at night.
🔹 Make sure your house number is visible from the road.
🔹 Secure pets before responders enter.
🔹 Unlock the door if you're able.
🔹 Have medications or an updated medication list available.
🔹 If someone can safely meet the ambulance outside, especially at a difficult-to-find rural location, it can help guide responders in.
And most importantly:
If the patient's condition changes while you're waiting, tell the dispatcher.

So what actually happens after you call 911?
📞 CALL → 📻 DISPATCH → 🚑 RESPONSE → 🩺 ASSESSMENT → 💊 TREATMENT → 🏥 TRANSPORT DECISION → 🚑 CONTINUED CARE → 🏥 HOSPITAL HANDOFF
You're not simply calling for an ambulance.
You're activating an emergency medical system designed to bring medical care to you.
The lights and sirens are the part everyone notices.
Everything happening before, during and after them is the part we want our community to understand.
