Severe Bleeding: What to Do in the First Three Minutes
Severe bleeding is the emergency a bystander is most likely to be able to fix. It is also the one where the folk technique — pile on more cloth and hope — actively works against you.
The Australian guidance is precise and slightly counterintuitive: pressure must be concentrated over the bleeding point, and adding more padding spreads the force out rather than increasing it. Getting that one detail right is most of the skill.
The 10-minute version
- Firm direct pressure over the bleeding point, with your hands or a pad. Hard enough to stop the bleeding, and held.
- One or two pads, not a stack. One to two pads over a small area achieve greater pressure over the bleeding point than continuing to layer more on top.
- A tourniquet is for life-threatening limb bleeding that direct pressure cannot control. Not over a joint or a wound, never covered by clothing or bandage, and a commercial windlass design beats an improvised one.
Do this, in this order
1. Look after yourself first. Gloves if you have them, a plastic bag if you do not. Check the scene is safe — traffic, machinery, power.
2. Call 000, or have someone else call while you work. Say the location first.
3. Apply firm direct pressure to the bleeding point. Hands if that is all you have, ideally with a pad. Press hard. This is not gentle, and it is uncomfortable for the casualty — that is expected.
4. Do not keep adding pads. If blood soaks through, resist the instinct to build a pile. One or two pads over a small area give more pressure over the bleeding point than a stack. If the first pad is saturated, keep pressing rather than diluting your force across layers.
5. Lay them down. Flat is better than sitting; sitting is better than standing. It helps blood pressure and it removes the risk of a fall if they faint.
6. Keep them warm. A blanket or jacket. Cold makes bleeding worse and shock more likely.
7. Maintain pressure until help arrives. Do not release to check every thirty seconds. Each release restarts the clot.
8. If bleeding is life-threatening, from a limb, and pressure is not controlling it — use a tourniquet.
Tourniquets, correctly
Australian guidance is clear that the risks of first aid tourniquet use are less than the risk of uncontrolled, life-threatening bleeding. The old fear of tourniquets has been substantially revised, and the modern position is that hesitation is the greater danger.
The rules:
- Only for a limb, and only for life-threatening bleeding not controlled by direct pressure.
- Not over a joint, and not over the wound.
- Never cover it with clothing or a bandage. It has to be visible to everyone who arrives after you.
- Commercially manufactured windlass tourniquets, of the type based on military designs, are more effective than improvised ones. If you carry one thing beyond bandages, carry one of these.
- Tighten until the bleeding stops. A tourniquet that is not tight enough to stop the bleeding is inflicting pain and doing nothing useful.
- Note the time it went on and tell the ambulance crew.
- Do not remove it. That decision belongs in hospital.
An improvised tourniquet — a wide strap and a rigid windlass — is better than nothing in a genuine limb emergency, but expect it to be harder to apply and less reliable. Narrow material like cord or wire causes damage without controlling flow.
Wound packing and haemostatic dressings
For severe, life-threatening bleeding from a site not suitable for a tourniquet — a groin, an armpit, a neck or torso junction — or from a limb where no tourniquet is available or one has failed, Australian guidance suggests a haemostatic dressing, if you are trained in its use and one is available.
That “if trained” is doing real work. Packing a wound is a physical technique: gauze pushed firmly into the cavity, right down onto the bleeding vessel, then pressure held on top for several minutes. Done half-heartedly, it does nothing. It is worth learning properly on a course rather than from an article.
What actually goes wrong
Stacking pads. The single most common mechanical error, and it reduces pressure at exactly the point that needs it.
Not pressing hard enough. Effective pressure is firmer than most people are comfortable applying to an injured person.
Releasing to check. Every look restarts the bleeding and disrupts clotting. Press and hold.
Hesitating over a tourniquet. The risk calculus has changed and the guidance is explicit that uncontrolled bleeding is the bigger danger.
Covering the tourniquet. Hospital staff need to see it immediately.
Using something narrow as an improvised tourniquet. Cord, wire and cable ties cause harm without stopping arterial flow. Wide and rigid, or not at all.
Forgetting the casualty’s temperature. Shock and cold compound each other, and a jacket is free.
Standing the person up. Fainting on top of a serious bleed adds a head injury.
Thresholds
| Situation | The rule |
|---|---|
| Any severe bleeding | Firm direct pressure over the bleeding point, immediately |
| Padding | 1–2 pads over a small area. Never a growing stack |
| Blood soaking through | Keep pressing. Do not layer more on |
| Life-threatening limb bleed not controlled by pressure | Tourniquet — high, tight, visible, timed |
| Tourniquet placement | Not over a joint, not over the wound |
| Junctional bleeding (groin, armpit, neck) | Pressure, and a haemostatic dressing if trained and available |
| Casualty position | Lying down, kept warm |
| Removing anything | Never. Bandages, packing and tourniquets come off in hospital |
| Embedded object | Do not pull it out. Pressure around it, not on it |
Building the capability
In the house: a proper first aid kit with real quantities of gauze and two decent bandages, not a box of small plasters.
In the car: the same, plus gloves and shears. Road trauma is the most likely scenario in which you will use any of this.
In a walking or work pack: two wide elasticised bandages cover both severe bleeding and snake bite, which is a good return for 200 grams.
In your head: a first aid course. Bleeding control is physical, and reading it does not transfer. Compression, packing and tourniquet application are all things your hands need to have done once.
What it costs
| Tier | Spend | What it buys |
|---|---|---|
| Free | $0 | Knowing to press hard on the point, not to stack pads, and not to release. Improvised pads from a clean t-shirt |
| Solid | ~$40–70 | Gloves, sterile gauze in useful quantity, two wide elasticised bandages, blunt-nosed shears |
| Better | ~$120–180 | The above plus a commercial windlass tourniquet and a haemostatic dressing |
| Best value | ~$150–250 | A hands-on first aid course, refreshed every three years |
The drill: ten minutes, twice a year
- Find your kit. In the dark, from where you actually sleep. If it takes more than a minute, move it.
- Open it and check the gauze quantity. Most retail kits have enough for a nosebleed and nothing more. Add to it.
- Practise pressure. On your own forearm, with a folded pad, for three full minutes without looking. Three minutes is longer than it sounds, and that is the point.
- If you own a tourniquet, apply it to your own thigh over clothing — snug, not fully tightened. Learn where the windlass sits and how the strap feeds. Doing this once removes most of the hesitation.
- Check expiry dates on dressings and replace what has aged out.
- Say the sequence out loud: call, pressure, one or two pads, lie down, keep warm, do not release.
Frequently asked questions
How do I stop severe bleeding?
Firm direct pressure over the bleeding point with your hands or a pad, hard enough to stop the flow, held continuously. Call 000, lie the person down, keep them warm, and do not release to check.
Should I keep adding bandages if blood soaks through?
No. One or two pads over a small area produce more pressure over the bleeding point than a growing stack. Keep pressing rather than layering.
When should I use a tourniquet?
For life-threatening bleeding from a limb that direct pressure cannot control. Place it not over a joint or the wound, tighten until bleeding stops, leave it visible, note the time, and do not remove it.
Are tourniquets dangerous?
Australian guidance is explicit that the risks of first aid tourniquet use are less than the risk of uncontrolled, life-threatening bleeding. Commercially made windlass tourniquets work better than improvised ones.
What about bleeding I cannot put a tourniquet on?
For severe bleeding at a junction — groin, armpit, neck — apply pressure, and use a haemostatic dressing if you are trained in its use and have one. Wound packing is a physical technique best learned on a course.
Should I remove an object stuck in a wound?
No. Leave it in place and apply pressure around it rather than on it — the object may be limiting the bleeding, and removing it can make things dramatically worse.
