The “Call” step in first aid is the second action in the Check, Call, Care sequence: after you check the scene and the person for signs of a life-threatening problem, you immediately call 911 (or your local emergency number) to get professional help on the way. It also includes retrieving or sending someone to get emergency equipment like an AED. This step matters because the sooner paramedics are dispatched, the better the outcome for the person in trouble.
How Check, Call, Care Works Together
The American Red Cross teaches a three-step framework for responding to any emergency. First, you Check the scene to make sure it’s safe for you to approach, then check the person to assess what’s wrong. Second, you Call 911 or tell someone nearby to call. Third, you Care for the person by providing whatever first aid you can until help arrives. The Call step sits in the middle because you need information from the Check step to relay to the dispatcher, and you need the dispatcher’s guidance before or while you begin Care.
When to Make the Call
Not every injury requires a 911 call. You should call emergency services when the person is unresponsive, is not breathing or only gasping, is having trouble breathing, has life-threatening bleeding, or has any other obvious condition that could kill them. Beyond those clear-cut situations, call 911 when the person’s condition could worsen on the way to a hospital, when moving them could cause further injury (such as a suspected neck or spinal injury after a car crash), or when the person needs equipment or skills that only paramedics carry.
Traffic and distance matter too. If you’re in a rural area or heavy congestion would delay a drive to the emergency room, calling 911 gets an ambulance with lights and sirens dispatched to you instead.
What to Tell the Dispatcher
When the dispatcher answers, they’ll guide the conversation, but being ready with key details speeds everything up. Provide your exact address or location, including landmarks or cross streets if you’re outdoors. Describe what you see: whether the person is conscious, breathing, bleeding, warm or cold to the touch, or has visible injuries. Give your phone number so the dispatcher can call you back if the line drops. If you’re calling from a group home or a care facility, mention that and identify yourself as a caregiver, since it changes how responders prepare.
Stay as calm as you can and answer the dispatcher’s questions directly. They are trained to pull the right information from you quickly, even under stress.
The Dispatcher Can Coach You Through First Aid
One of the most valuable parts of the Call step is that it connects you to someone who can walk you through lifesaving actions in real time. Dispatchers are trained to give what’s known as pre-arrival instructions: step-by-step guidance tailored to your specific emergency. If someone’s heart has stopped, a dispatcher can talk you through chest compressions even if you’ve never done CPR. If someone is choking, they can guide you through abdominal thrusts. They can also help with controlling severe bleeding, assisting with childbirth, flushing chemical exposures from the skin or eyes, and protecting someone who is having a seizure.
These instructions are scripted in plain language so any non-medical person can follow them. Research shows that when dispatchers use a structured set of questions about consciousness and breathing, they correctly identify cardiac arrest more than 80% of the time. That accuracy matters because it means you’ll get the right guidance fast. Dispatchers assume you’re willing to help simply because you called. They won’t ask “are you willing to do CPR?” because phrasing it as optional can discourage people from acting.
Ask Someone to Get an AED
If you’re responding to someone who has collapsed and might be in cardiac arrest, the Call step also includes getting an AED (automated external defibrillator) to the scene. If other people are nearby, delegate: point at a specific person and tell them to call 911 while you point at another and tell them to find the nearest AED. Many public buildings, airports, gyms, and schools have AEDs mounted on walls. If you’re alone, call 911 first, put the phone on speaker, then retrieve the AED yourself if one is close by. Start chest compressions as soon as you return and keep going until the AED is powered on and gives you instructions.
Emergency Numbers Outside the U.S.
If you’re traveling, the number you call changes by country. In the United States, it’s 911. In the United Kingdom, dial 999 or 112. Across most of the European Union, 112 is the standard emergency number. In Australia, the landline number is 000, but dialing 112 from a cell phone also works. Saving the local emergency number in your phone before you travel is a simple step that removes one barrier in a crisis.
Using Your Smartphone’s Emergency Features
Modern smartphones have built-in tools that make the Call step faster and more effective. On most phones, pressing the power button five times rapidly triggers an Emergency SOS mode that automatically dials emergency services after a short countdown. When you place an emergency call from a smartphone, your phone’s GPS location can be sent to dispatchers automatically, which helps responders find you even if you can’t describe exactly where you are.
Setting up a Medical ID on your phone is another way to support the Call step, even if you’re the one who needs help. Emergency workers can view your Medical ID from the lock screen without needing your passcode. It displays critical details like drug allergies, medical conditions, medications, and emergency contacts. On iPhones, you can also enable a setting that automatically shares your Medical ID with emergency services whenever you place a 911 call or send an emergency text. If you come across an unconscious person carrying a smartphone, you can access their Medical ID the same way and relay that information to the dispatcher.
Tips for an Effective Call
- Don’t hang up first. Let the dispatcher end the call. They may have additional questions or instructions as the situation evolves.
- Use speaker mode. Putting your phone on speaker frees your hands to perform CPR, apply pressure to a wound, or operate an AED.
- Delegate when possible. Point at a specific person and give them a clear task: “You, in the blue shirt, call 911.” Singling someone out prevents the bystander effect where everyone assumes someone else will call.
- Stay with the person. Even after the call is placed, do not leave them alone. Continue providing care and relay any changes in their condition if you call the dispatcher back.
- Unlock doors or gates. If responders will need to get through a locked entrance, send someone to open it or prop it open so paramedics aren’t delayed at the door.
