Fainting, Nosebleeds, and Minor Wound Care: Everyday First Aid Done Right
The emergencies that happen most — and the ones most people handle slightly wrong. Here is how to do them right, plus the simple test for whether a cut needs stitches.
Nosebleed: sit up, lean forward (never tip the head back), and pinch the soft part of the nose for a full 10–15 minutes without letting go. Seek care if it won’t stop after 20–30 minutes, is very heavy, or followed a head or face injury.
Fainting: lay the person on their back and raise their legs about 30 cm. Most recover in a minute or two. Call 911 if they don’t wake quickly, are injured, have chest pain or trouble breathing, or fainted without warning or during exercise.
Minor wound: stop bleeding with firm pressure, rinse under clean running water (no hydrogen peroxide or iodine inside the wound), then cover. Get stitches if a cut gapes open, is deeper than ~6 mm or longer than ~2 cm, is on the face or across a joint, or won’t stop bleeding.
Not every first aid moment is a dramatic one. Far more often it is a kid with a streaming nosebleed, a coworker who goes pale and crumples at the sight of a needle, or a deep slice from a kitchen knife while making dinner. These everyday situations are rarely dangerous — but they are surprisingly easy to get wrong, and the wrong response can make things worse or slow healing. This guide covers all three, and answers the question everyone eventually asks while staring at a cut: does this need stitches?
Fainting
Fainting (the medical term is syncope) happens when blood flow to the brain briefly drops, usually triggered by standing too long, heat, pain, fear, the sight of blood, dehydration, or standing up too fast. The person goes pale, feels dizzy or sweaty, and loses consciousness for a few seconds to a minute.
1Catch it early if you can
If someone says they feel lightheaded, sweaty, or “funny,” or looks suddenly pale, help them sit or lie down right away — before they fall and hurt themselves. Getting them down is the goal.
2Lay them down and raise the legs
If they have fainted, lay them flat on their back and raise their legs about 30 cm (a foot) on a chair, bag, or your arm. This helps blood flow back to the brain. Loosen tight clothing at the neck and waist and make sure they have fresh air.
3Check breathing and stay with them
Most people come round within a minute or two. Reassure them as they wake — fainting is disorienting. Keep them lying down for a few more minutes, then let them sit up slowly. Offer water once they are fully alert.

Nosebleeds
Most nosebleeds come from a cluster of small, fragile blood vessels at the front of the nose and look far scarier than they are. The trouble is that the most popular technique — tilting the head back — is exactly wrong. It sends blood down the throat, which can irritate the stomach and cause coughing or vomiting, and it hides whether the bleeding has actually stopped.
1Sit up and lean forward
Have the person sit upright and tip their head slightly forward, not back. This keeps blood draining out of the nose rather than down the throat.
2Pinch the soft part of the nose
Pinch the soft part just below the bony bridge — the fleshy section — firmly between thumb and finger. Hold steady pressure for a full 10 to 15 minutes without letting go to peek. Releasing early to check restarts the clock. Breathe through the mouth.
3Aftercare
Once it stops, avoid blowing the nose, bending over, or heavy lifting for several hours so the clot can settle. Do not pick or rub the nose. Avoid stuffing tissue up the nostril, which can dislodge the clot when removed.
Source: Canadian Red Cross first aid (sit-up, lean-forward, pinch 10–15 min). A cold pack on the bridge is sometimes suggested, but international resuscitation review (ILCOR, FA 7151) found insufficient evidence that cooling adds benefit — the pinch is what stops the bleed.
Minor Wound Care
For cuts, scrapes, and grazes that are not heavily bleeding, good wound care prevents infection and helps healing.
1Wash your hands and stop the bleeding
Clean your hands first (or wear gloves). Apply firm, direct pressure with a clean cloth or dressing until the bleeding stops. Most minor wounds stop within a few minutes.
2Rinse the wound with clean water
Hold the wound under clean running water to flush out dirt and debris. Avoid pouring hydrogen peroxide, rubbing alcohol, or iodine directly into the wound — they damage healthy tissue and slow healing. Plain water (or saline) is best.
3Dry, protect, and cover
Pat the area dry, apply a thin layer of antibiotic ointment or plain petroleum jelly if you have it (this keeps the wound moist and helps healing), and cover with a clean bandage or dressing.
4Change the dressing and watch for infection
Change the dressing daily, and whenever it gets wet or dirty. Watch for signs of infection: spreading redness, increasing warmth, swelling, pus, increasing pain, red streaks, or fever. See a doctor if any appear.

Does This Wound Need Stitches?
This is one of the most-searched first aid questions. As a guide, a wound likely needs stitches (or medical glue/closure) if it:
- Is deeper than about 6 mm, or you can see fat, muscle, or bone
- Gapes open — the edges do not naturally fall together
- Is longer than about 2 cm
- Keeps bleeding after 10 to 15 minutes of firm, direct pressure
- Is on the face, or across a joint (knuckle, knee, elbow) where movement pulls it open
- Was caused by something dirty, rusty, or a bite (human or animal)
- Has dirt or debris you cannot rinse out
- Causes numbness or loss of movement beyond the cut (possible nerve or tendon injury)
Source: Canadian Red Cross first aid and general medical wound-care guidance — deep wounds (fat, muscle, or bone visible), gaping or long (> ~2 cm) cuts, persistent bleeding after 10–15 minutes of direct pressure, and wounds to the face, over a joint, from a bite, or heavily contaminated warrant same-day medical assessment for closure.
For Serious Bleeding, Different Rules Apply
This article covers minor wounds. If bleeding is severe — spurting, soaking through dressings, or from a major injury — it is a life-threatening emergency: call 911 and apply firm, continuous direct pressure to the wound, adding more dressings on top rather than removing soaked ones. Controlling serious bleeding is a hands-on skill taught in every Standard First Aid course.
The Skills You’ll Actually Use Most
Cardiac arrest is rare; nosebleeds, faints, and cuts are weekly events in family life. A Life Safe first aid course gives you hands-on practice with all of them — wound dressing, the recovery position, bleeding control — alongside CPR, so you are genuinely ready for both the everyday and the emergency.
Frequently Asked Questions
What is the correct way to stop a nosebleed?
Sit upright and lean slightly forward — never tilt the head back, which sends blood down the throat. Pinch the soft part of the nose just below the bony bridge and hold firmly for a full 10 to 15 minutes without releasing to check. Breathe through your mouth. Seek care if it continues past 20 to 30 minutes, is very heavy, or followed a serious head or face injury. This is standard Canadian Red Cross / Heart & Stroke guidance.
What should you do if someone faints?
Help them sit or lie down before they fall if you sense it coming. If they have fainted, lay them on their back and raise their legs about 30 cm to help blood reach the brain. Loosen tight clothing and provide fresh air. Most recover within a minute or two. Call 911 if they don’t wake quickly, are injured, have chest pain or trouble breathing, or fainted without warning or during exercise.
How do I know if a cut needs stitches?
Likely yes if it is deeper than about 6 mm, gapes open, is longer than about 2 cm, won’t stop bleeding after 10 to 15 minutes of pressure, is on the face or across a joint, exposes fat, muscle, or bone, or came from something dirty or a bite. When in doubt, get it checked — stitches work best placed within a few hours.
How do you clean and dress a minor wound?
Wash your hands, stop bleeding with firm pressure, then rinse the wound under clean running water — avoid hydrogen peroxide or iodine inside it. Pat dry, apply a thin layer of antibiotic ointment if available, and cover with a clean bandage. Change the dressing daily and when wet or dirty, and watch for infection signs like spreading redness, warmth, pus, or fever.
