A person can bleed to death from a severe injury in minutes, often before an ambulance reaches the scene. That is why early action matters. The goal is not to “fix” the injury. The goal is to keep the person alive until trained responders take over.
This guide covers practical first aid steps a bystander can take after a shooting injury: how to stay safe, call 911, stop life-threatening bleeding, protect breathing, prevent shock, and avoid harmful mistakes. It is informational only and does not replace certified first aid, CPR, Stop the Bleed, or emergency medical training.
The order below follows a simple logic: scene safety first, then emergency response, then bleeding and breathing, then comfort and handoff.
1. Make sure the scene is safe before you rush in
The first rule is hard but necessary: do not become another victim.
If there is still a threat nearby, move away, take cover, and call 911 as soon as it is safe. Do not run toward gunfire, enter an active threat area, or try to disarm someone. Emergency medical care cannot help anyone if the scene is still dangerous.
Look for signs that the area is unsafe:
Ongoing gunfire or shouting
A visible weapon near the injured person
Traffic, fire, smoke, or unstable structures
Crowds that could turn chaotic
Broken glass, sharp metal, or other hazards
If the person can move, guide them to cover or a safer area. Use short, clear words.
“Come this way.”
“Stay low.”
“Keep pressure on that spot.”
If the person cannot move and the danger is active, prioritize your safety and give information to 911. Dispatchers can guide you based on the situation.
The American Red Cross and Stop the Bleed training both stress a basic point: a rescuer must first make sure the scene is safe enough to provide care. In a shooting, that may mean waiting for law enforcement or other trained responders before approaching.
2. Call 911 and give clear, useful information
Call 911 as early as possible. Put the phone on speaker if you need both hands free. If other people are nearby, point to one person and assign the call.
Say something direct:
“Call 911 now. Tell them there is a shooting injury and we need an ambulance.”
Do not assume “someone already called.” In emergencies, people often freeze or think another bystander has handled it.
Give the dispatcher:
The exact location, including building name, cross street, floor, apartment, room, or landmark
The number of injured people, if known
Whether the scene is safe or the threat is still nearby
Whether the person is awake and breathing
Where the heavy bleeding is coming from
What first aid is being done, such as direct pressure or a tourniquet
Stay on the line unless the dispatcher tells you to hang up or you must move for safety. Dispatchers can talk you through CPR, bleeding control, or positioning.
If someone else is available, send them to meet responders. A person standing outside, waving down police, fire, or EMS, can save critical time.
This is where saving lives, treatment, emergency response all connect. The faster dispatchers and responders know what is happening, the faster the right help reaches the patient.
3. Check responsiveness and breathing
Once the scene is safe enough to approach, quickly check whether the person responds.
Use a loud voice.
“Can you hear me?”
“What is your name?”
“Squeeze my hand.”
If they respond, keep them as calm and still as possible. If they do not respond, check breathing. Look for normal chest movement. Listen for breath sounds if you can. Feel for air from the mouth or nose if it is safe to get close.
Do not spend a long time checking. A few seconds is enough to decide what to do next.
If the person is not breathing normally, tell 911 and start CPR if you are trained or if the dispatcher instructs you. If an automated external defibrillator, known as an AED, is nearby, send someone to get it. An AED will not treat blood loss, but it can help if the person has a shockable heart rhythm.
If the person is breathing but unconscious, keep the airway open. If there is no suspected spine injury and you must leave briefly or they are vomiting, the recovery position may help keep the airway clear. In many trauma cases, though, it is best to avoid unnecessary movement unless breathing, bleeding, or safety requires it.
A simple order helps:
Check if they respond.
Check if they breathe normally.
Tell 911 what you find.
Start CPR if needed and instructed.
4. Find the life-threatening bleeding fast
With serious trauma, heavy bleeding is one of the most urgent threats. Stop the Bleed, a national public education campaign led by the American College of Surgeons and partner organizations, teaches that bystanders can often control severe bleeding before EMS arrives.
Look for bleeding that is:
Spurting or pumping
Flowing steadily and heavily
Soaking clothing or pooling on the ground
Coming from an arm, leg, neck, groin, shoulder, or chest area
Associated with confusion, pale skin, or weakness
A gunshot wound can have both an entrance and an exit wound. If you can do so without wasting time, check the other side of the body. Blood may be hidden under dark clothing, jackets, or the person’s body.
Use gloves if available. If not, use a barrier such as a clean plastic bag, cloth, or several layers of gauze. Personal protection matters, but do not delay urgent bleeding control if the situation is severe and you choose to help.
If there are multiple injuries, treat the worst bleeding first. A small amount of bleeding from one spot matters less than bright, heavy flow from another.
Do not get distracted by dramatic but less urgent issues. A person may be screaming from pain, but heavy bleeding can be the immediate life threat. Stay focused on what can kill fastest.
5. Put firm, direct pressure on the bleeding
Direct pressure is the foundation of bleeding control. Use gauze, a clean cloth, a shirt, a towel, or your gloved hand if nothing else is available.
Press directly on the bleeding site. Use the heel of your hand and lean your body weight into it. This may feel like more pressure than expected. Severe bleeding needs firm, constant force.
Do this:
Expose the wound enough to find the source of bleeding.
Place gauze or cloth directly over the bleeding point.
Press hard and do not keep lifting the dressing to check.
Add more cloth or gauze if blood soaks through.
Keep pressure until EMS arrives or until another bleeding control method is needed.
Do not remove a soaked dressing. Pulling it away can disturb early clotting. Add more layers on top and keep pressing.
If the person can help, have them press on their own wound while you call 911, gather supplies, or check for other bleeding. Give clear instructions.
“Press hard right here.”
“Do not let go.”
“I’m going to add more gauze.”
Pain is expected. Pressure can hurt, especially over damaged tissue. Explain what you are doing, but do not ease up if bleeding is severe.
For wounds in areas where pressure is hard to hold, such as the neck, shoulder, groin, or armpit, pack the wound if you have training and supplies. More on that next.
6. Pack deep bleeding wounds when pressure alone is not enough
Wound packing is used for severe bleeding from places where a tourniquet cannot be applied, such as the groin, armpit, shoulder, or deep muscle areas. Stop the Bleed courses teach packing as a core skill because pressure on the surface may not reach the bleeding vessel in a deep wound.
Use hemostatic gauze if available. Hemostatic gauze contains agents that help blood clot. If you do not have it, use regular gauze or clean cloth.
Basic steps:
Find the bleeding source.
Push gauze firmly into the wound cavity.
Keep feeding gauze in until the space is packed tightly.
Place both hands over the packed wound.
Hold steady pressure for several minutes or until help arrives.
This is not gentle first aid. It is lifesaving first aid. Severe bleeding from a deep wound may not stop unless the material fills the space and pressure reaches the source.
Do not pack wounds in the chest or abdomen. For those areas, use direct pressure around the wound when appropriate and follow dispatcher guidance. Chest wounds have special concerns because air can enter the chest cavity and interfere with breathing.
If the person becomes pale, sweaty, confused, or very weak, tell 911. These can be signs of shock from blood loss.
7. Use a tourniquet for severe arm or leg bleeding
A tourniquet can save a life when an arm or leg is bleeding heavily and direct pressure is not enough, or when you cannot maintain pressure because of danger, multiple victims, or the need to move.
Modern emergency guidance supports tourniquet use for life-threatening extremity bleeding. Military experience and civilian trauma training helped change older advice that treated tourniquets as a last resort. Current Stop the Bleed instruction teaches bystanders to use them when severe arm or leg bleeding is present.
Use a commercial tourniquet if available. Common emergency tourniquets have a strap and a windlass, which is the rod used to tighten the band.
Place it:
On the injured arm or leg
Two to three inches above the bleeding wound if visible
Not directly over a joint
Higher on the limb if you cannot see the wound clearly
Tighten it until bleeding stops. This will hurt. A loose tourniquet does not help and may make bleeding worse by blocking veins without stopping arterial flow.
After applying it:
Secure the windlass or tightening device.
Note the time it was applied.
Tell EMS where it is and when it went on.
Do not remove it.
Do not loosen it to “let blood flow.”
If bleeding continues, tighten the tourniquet more. If it still does not stop, apply a second tourniquet above the first if available.
Avoid improvised tourniquets unless there is no commercial device and the bleeding is life-threatening. Belts, cords, and thin materials often fail or cause extra harm. A wide cloth with a rigid windlass can work in some emergencies, but training matters.
A tourniquet is for arms and legs. It is not used around the neck, chest, abdomen, or pelvis.
8. Seal an open chest wound if air is moving through it
A shooting injury to the chest can create a dangerous problem: air may enter the chest cavity through the wound. This can make it harder for the lung to work. Signs may include trouble breathing, bubbling or sucking sounds from the wound, coughing blood, worsening anxiety, or bluish lips.
If you see an open chest wound and have a commercial chest seal, use it. These seals are designed to stick to the skin and help block air from entering the wound. Many trauma kits include vented chest seals, which allow trapped air to escape.
If no chest seal is available, dispatchers may guide you based on what you have. Some emergency training programs teach using a clean plastic wrapper or similar airtight material taped on three sides, but current advice varies by training program and local protocol. If you are unsure, follow 911 instructions.
Key points:
Keep the person as still as possible.
Help them sit or lie in the position that makes breathing easiest, unless CPR or bleeding control requires another position.
Watch for worsening breathing.
Be ready to start CPR if they stop breathing normally.
Tell EMS if you applied any seal or covering.
Do not press deeply into the chest wound. Do not try to remove a bullet or object. Do not give food or drink.
If there is both heavy external bleeding and breathing trouble, do the best you can with help from others. One person can maintain pressure while another talks to 911 or watches breathing.
9. Do not remove bullets, clothing stuck to wounds, or large objects
In movies, someone often digs out a bullet with whatever tool is nearby. In real life, that can cause more bleeding, more tissue damage, and infection risk. Leave bullets and fragments alone.
If there is an object stuck in the wound, such as glass, metal, or another foreign object, do not pull it out. It may be pressing against a damaged blood vessel. Removing it can trigger severe bleeding.
Instead:
Stabilize the object with bulky dressings around it.
Apply pressure around the wound, not directly on the object.
Keep the person still.
Tell EMS what you found.
If clothing blocks access to heavy bleeding, cut or tear it away if you can. Do not waste time trying to preserve clothing. If fabric is stuck inside the wound, do not yank it out. Work around it and control the bleeding.
Do not clean a severe wound with water, alcohol, hydrogen peroxide, or antiseptic during the emergency. Infection prevention matters later, but bleeding and breathing come first. Pouring liquid into a deep wound does not save time and may interfere with clotting.
Avoid giving the person medication unless a dispatcher or medical professional tells you to. Aspirin, ibuprofen, naproxen, alcohol, or other substances can worsen bleeding or complicate care.
10. Treat for shock while you wait for EMS
Shock happens when the body cannot circulate enough oxygen-rich blood to vital organs. Severe bleeding is a common cause after trauma. A person in shock can look alert at first, then decline quickly.
Watch for:
Pale, cool, or clammy skin
Fast breathing
Weakness or dizziness
Confusion or agitation
Nausea or vomiting
Sleepiness or loss of consciousness
A feeling of doom or extreme fear
Keep the person as still as possible. Movement can worsen bleeding. Help them lie down if that is comfortable and does not make breathing harder. If they have a chest injury or trouble breathing, they may breathe better sitting partly upright.
Cover them with a jacket, blanket, or emergency blanket. Trauma patients can lose body heat fast, even in warm weather. Hypothermia can make bleeding harder to control because the body’s clotting process works poorly when core temperature drops.
Do not give food or drink. Surgery or anesthesia may be needed, and eating or drinking can increase risk if they vomit or need airway support.
Keep talking in a calm voice.
“Help is on the way.”
“You’re doing well.”
“Keep breathing slowly.”
“I’m staying with you.”
Reassurance is not just kindness. Panic can increase movement and make first aid harder. Calm, clear instructions help the person cooperate.
11. Keep reassessing until responders take over
Emergency first aid is not one action. It is a cycle of checking and correcting.
Every minute or so, reassess:
Is the scene still safe?
Is the person awake or becoming less responsive?
Are they breathing normally?
Has the bleeding restarted?
Is the tourniquet still tight?
Is pressure still firm and directly over the bleeding?
Are they getting colder?
Has anything changed that 911 needs to know?
If bleeding starts again, press harder, adjust your hand position, add more gauze, or tighten the tourniquet if one is being used. If the person stops breathing normally, tell 911 and start CPR if instructed.
If several bystanders are helping, assign jobs.
One person calls 911.
One person controls bleeding.
One person watches breathing.
One person guides responders to the exact location.
Simple roles reduce confusion. They also stop people from crowding around and doing nothing useful.
Do not let the injured person stand up or walk around just because they feel better. Adrenaline can hide the severity of blood loss. A person can speak clearly and still be in danger.
12. Give EMS a clear handoff
When police, firefighters, or EMS arrive, make room and follow instructions. They may move quickly. They may ask direct questions while working.
Give a short handoff:
What happened, if known
When it happened, approximately
Where you found bleeding
What first aid you provided
Whether a tourniquet was used
What time the tourniquet was applied
Whether the person lost consciousness
Any changes in breathing or responsiveness
If you applied pressure, do not suddenly let go unless a responder tells you to. They may want you to keep holding pressure while they prepare equipment.
If you used a tourniquet, point to it. If clothing or blankets cover it, make sure EMS sees it. Tourniquet time matters for hospital care.
After responders take over, step back unless they ask you to assist. You may be shaken, even if you stayed calm during the emergency. That is normal. If police need a statement, give facts, not guesses.
Common mistakes that can make things worse
Good intentions are not enough in severe trauma. Some actions can delay care or increase harm.
Avoid these common mistakes:
Moving the person without a safety or medical reason
Spending time looking for the bullet
Removing a stuck object
Giving food, water, alcohol, or pain pills
Using a loose tourniquet
Taking a tourniquet off after bleeding stops
Checking the wound every few seconds
Pressing near the bleeding instead of directly on it
Packing a chest or abdominal wound
Waiting to call 911 until after trying first aid
The best approach is simple and focused: get help coming, stop major bleeding, support breathing, prevent shock, and keep reassessing.
What to keep in a basic trauma kit
A standard home first aid kit often has bandages for small cuts, pain relievers, and antiseptic wipes. Those items are useful, but they do not control severe bleeding well. A trauma kit is different.
Useful supplies include:
Nitrile gloves
Several rolls of sterile gauze
Hemostatic gauze
Pressure dressing
Commercial tourniquet
Vented chest seals
Trauma shears
Emergency blanket
Permanent marker
CPR face shield
Small instruction card
Store kits where people can reach them fast: car, workshop, range bag, school safety cabinet, church, community center, or home entry area. Check expiration dates on packaged medical supplies. Replace damaged or opened items.
Training matters more than gear. A tourniquet in a drawer helps only if someone knows when and how to use it. Stop the Bleed classes are often taught by hospitals, fire departments, emergency medical services, schools, and community groups across the U.S. The American Red Cross and American Heart Association also offer first aid and CPR training.
FAQ
Can I use a belt as a tourniquet?
A belt is usually a poor tourniquet because it is hard to tighten enough to stop arterial bleeding. Use a commercial tourniquet if available. If there is life-threatening arm or leg bleeding and no commercial device, follow 911 instructions and use the best wide material available with a rigid windlass if trained.
Should I remove the bullet if I can see it?
No. Do not remove bullets, fragments, or objects stuck in a wound. Removing them can cause more bleeding and tissue damage. Control bleeding, keep the person still, and wait for EMS.
What if I do not have gloves?
Use gloves if you have them. If not, use a barrier such as a clean plastic bag, towel, or layers of cloth if available. Severe bleeding is time-critical, so make the safest choice you can without delaying lifesaving care.
Should I pour water or alcohol on the wound?
No. In the emergency phase, focus on bleeding control and breathing. Do not pour water, alcohol, hydrogen peroxide, or antiseptic into a deep wound. Medical teams can clean and treat the wound later.
What if the person says they feel fine?
Do not let them walk around. Adrenaline can hide pain and blood loss. Keep them still, monitor breathing and bleeding, cover them to prevent heat loss, and wait for responders.
The lifesaving takeaway
The best first aid for a shooting injury is fast, simple, and focused. Get to safety. Call 911. Stop severe bleeding with direct pressure, wound packing, or a tourniquet when appropriate. Protect breathing. Keep the person warm and still. Give responders a clear handoff.
You do not need to perform surgery. You do need to act early, stay calm, and use the right priorities. In the minutes before help arrives, those choices can keep someone alive.
