Basic First Aid Everyone Should Know: Step-by-Step Guide for Emergencies

In a medical emergency, what you do in the first minutes can save a life. This guide gives everyday people clear, step-by-step actions for common emergencies—from CPR and choking to burns, bleeding, heart attack, and more. It’s designed for parents, caregivers, teachers, coworkers, and anyone who wants to feel prepared to help until professionals arrive.

Stay Calm and Assess the Scene: Safety, Hazards, and Obtaining Consent

Take a breath and scan for danger. Your safety comes first. Look for traffic, electricity, fire, chemicals, unstable structures, violence, or aggressive animals. If the scene is unsafe, do not enter—call for help and keep others away. If it’s safe, introduce yourself, explain what you intend to do, and ask for consent. For a child, ask a parent/guardian if present. If the person is unresponsive or confused, consent is implied.

When and How to Call Emergency Services: What to Say and What to Expect

Call your local emergency number (e.g., 911 in the U.S., 112 in the EU, 999 in the UK, 000 in Australia). Put your phone on speaker so you can act while talking. Provide:

Location (address, landmarks, GPS if possible) and callback number
What happened and hazards present
Number of people injured and their age/sex if known
The person’s condition (responsive/unresponsive, breathing/not breathing, severe bleeding)
Expect the dispatcher to give pre-arrival instructions (e.g., CPR, AED use, bleeding control). Follow them. Do not hang up until told.

Primary Survey (DRABC): Danger, Response, Airway, Breathing, Circulation

Danger: Ensure the scene is safe.
Response: Tap and shout. Look for purposeful movement or speech.
Airway: If unresponsive, open the airway.
Breathing: Look, listen, and feel for normal breathing for up to 10 seconds. Agonal gasps are not normal.
Circulation/Catastrophic bleeding: Control life-threatening bleeding immediately. If not breathing normally, start CPR.

Airway and Breathing: Opening the Airway, Recovery Position, and Monitoring

Open the airway using head-tilt/chin-lift. If spinal injury suspected, use jaw-thrust if trained; otherwise prioritize opening the airway.

If breathing normally and no major trauma, place in the recovery position: roll onto side, top knee bent forward, head tilted slightly back, mouth downward to drain fluids. Avoid this if you suspect spinal, hip, or major pelvic injury unless vomiting.
Continuously monitor breathing and color. If breathing stops or becomes abnormal, begin CPR.

CPR Basics: Adult, Child, and Infant Recognition and Step-by-Step Actions

If unresponsive and not breathing normally, start CPR immediately.

Adults: Push hard and fast in the center of the chest at 100–120/min, depth 2–2.4 in (5–6 cm). Allow full recoil, minimize pauses. Ratio 30 compressions to 2 breaths if trained; otherwise do compression-only CPR.
Children (1 year to puberty): Same rate; depth about 1/3 chest (≈2 in/5 cm). Use one or two hands.
Infants (5 minutes, repeats without recovery, it’s the first seizure, the person is pregnant, injured, has trouble breathing afterward, or has diabetes.

Diabetic Emergencies: Low vs. High Blood Sugar Signs and Quick Treatments

Low blood sugar (hypoglycemia) signs: shakiness, sweating, hunger, irritability, confusion, seizure.
- If awake and able to swallow, give 15–20 g fast carbs (glucose tablets/gel, juice, regular soda). Recheck in 15 minutes; repeat if needed. Follow with a snack if the next meal is far away.
- If unconscious, do not give food/drink. Use glucagon if available and trained; call emergency services.
High blood sugar (hyperglycemia): thirst, frequent urination, fruity breath, drowsiness. Encourage fluids if alert; seek urgent care if vomiting, abdominal pain, or deep rapid breathing.

Poisoning and Overdose: Ingestion, Inhalation, Skin/Eye Exposure, and Poison Control

Call Poison Control (U.S.: 1-800-222-1222) or local equivalent. Do not induce vomiting.
Inhaled: move to fresh air. Skin: remove contaminated clothing, rinse skin with water. Eyes: irrigate with clean water for at least 15 minutes.
Suspected opioid overdose: slow/no breathing, pinpoint pupils. Call emergency services and give naloxone if available; repeat per instructions if no response.

Heat Illnesses: Heat Exhaustion vs. Heat Stroke—Cooling and Escalation

Heat exhaustion: heavy sweating, weakness, cool clammy skin, nausea, dizziness. Move to shade, cool with fans/ice towels, give cool fluids with electrolytes, loosen clothing.
Heat stroke (medical emergency): hot skin (may be dry or sweaty), confusion, seizure, fainting, temperature ≥104°F/40°C. Call emergency services. Begin rapid cooling: cold water immersion if available and safe; or ice packs to neck, armpits, groin; mist and fan. Cool first, transport second when possible.

Cold Emergencies: Hypothermia and Frostbite—Rewarming and Protection

Hypothermia: shivering, slurred speech, confusion, drowsiness. Move indoors, remove wet clothing, insulate with blankets, warm the trunk first. Handle gently; severe hypothermia can cause heart rhythm problems. Be ready to use an AED.
Frostbite: numb, hard, pale or waxy skin. Rewarm in warm (not hot) water 98–102°F (37–39°C) for 15–30 minutes only if refreezing won’t occur. Do not rub or use dry heat. Protect and seek medical care.

Drowning and Near-Drowning: Safe Rescue Priorities and Post-Resuscitation Care

Prioritize rescuer safety: reach, throw, row, then go (enter water only if trained).
If unresponsive and not breathing, start rescue breathing as soon as safely possible; begin CPR on firm ground with an AED when available.
After rescue, even if they seem okay, coughing, breathing difficulty, or fatigue warrants medical evaluation.

Eye Injuries: Irrigation, Shielding, and Chemical vs. Physical Trauma

Chemical exposure: irrigate immediately with clean water or saline for at least 15 minutes; remove contact lenses during flushing. Seek urgent care.
Penetrating injury: do not remove objects. Cover with a rigid shield (paper cup) without pressure and seek emergency care.
For minor debris, blink or rinse; avoid rubbing.

Dental Emergencies: Knocked-Out or Broken Teeth—Storage and Urgent Care

Knocked-out adult tooth: handle by the crown, not the root. Rinse gently if dirty. Reinsert into the socket if possible and bite on gauze. If not, store in milk, saline, or the person’s saliva (cheek pouch) and see a dentist immediately (ideally within 60 minutes). Do not store in water.
Broken tooth: save fragments, rinse mouth, control bleeding with gauze, use cold pack for pain/swelling.

Bites, Stings, and Ticks: Allergy Risk, Removal Techniques, and Infection Prevention

Bee stings: scrape stinger out quickly with a card or edge; wash area; ice for swelling. Monitor for anaphylaxis.
Animal/human bites: wash thoroughly with soap and water for 5 minutes, control bleeding, cover, and seek care—high infection risk; assess for tetanus and rabies.
Tick removal: use fine-tipped tweezers, grasp close to skin, pull steadily upward. Clean skin afterward. Watch for rash, fever, or flu-like symptoms.

Nosebleeds and Minor Ailments: Proper Techniques and When to Escalate

Nosebleed: sit up, lean forward, pinch the soft part of the nose continuously for 10–15 minutes. Spit out blood; avoid blowing. A topical decongestant spray (e.g., oxymetazoline) may help. Seek care if bleeding >20 minutes, very heavy, from injury, or on blood thinners.
Minor ailments: use over-the-counter pain relievers as labeled (avoid aspirin in children with viral illness). Hydrate and rest.

Secondary Survey: Head-to-Toe Check, SAMPLE History, and Vital Signs

After life threats are addressed, perform a systematic check for other injuries.

SAMPLE history: Symptoms, Allergies, Medications, Past medical history, Last oral intake, Events leading up.
Observe and record vital signs: breathing rate and quality, pulse rate and strength, skin color/temperature/moisture, level of responsiveness, pupils, capillary refill in children.

Infection Control: Hand Hygiene, PPE, Bloodborne Pathogen Precautions, and Cleanup

Use PPE (gloves, eye protection, mask) when possible. Avoid direct contact with blood/body fluids.
Perform hand hygiene before and after care.
Clean surfaces with appropriate disinfectant (e.g., 1:10 bleach solution for blood spills). Dispose of sharps safely and contaminated materials per local guidelines.

When to Stop First Aid: Handover to Professionals and Scene Changes

Stop or modify care when:

A trained professional takes over
You are too exhausted to continue
The scene becomes unsafe
The person recovers and has capacity to refuse care (document this if possible)

Aftercare and Monitoring: Red Flags, Follow-Up, and Pain Management Basics

Monitor for red flags: worsening pain/swelling, numbness, fever, shortness of breath, chest pain, confusion, repeated vomiting, new weakness.
Use rest, elevation, and appropriate over-the-counter pain relief as labeled unless contraindicated. Seek medical advice if symptoms persist or worsen.

Building a First Aid Kit: Essentials, Medications, and Personal Adaptations

Include: non-latex gloves, CPR face shield, assorted gauze, adhesive bandages, adhesive tape, triangular bandage, elastic wrap, sterile saline, alcohol/antiseptic wipes, hemostatic gauze, tourniquet, instant cold pack, tweezers, scissors, thermometer, space blanket, flashlight, splint, notepad/pen.
Medications: acetaminophen, ibuprofen, oral antihistamine (cetirizine or diphenhydramine), hydrocortisone cream, oral rehydration salts, glucose gel/tablets, adult aspirin (for suspected heart attack in adults).
Personalize with prescription meds (inhaler, epinephrine, nitroglycerin), copies of medical info, and emergency contacts. Check expirations regularly.

Special Considerations: Infants and Children, Older Adults, and Pregnancy

Infants/children: adjust techniques for size (e.g., CPR depth), use pediatric dosing, keep choking hazards in mind.
Older adults: higher fall and bleed risk; be cautious with neck/spine injuries; polypharmacy affects decisions.
Pregnancy: for choking use chest thrusts. For anaphylaxis or severe illness, position on left side if possible. In cardiac arrest, start standard CPR immediately; professionals may adjust positioning.

Mental Health First Aid: Panic Attacks, Suicidal Ideation, and Supportive Communication

Panic: speak calmly, coach slow breathing (in through nose 4 seconds, out 6 seconds), use grounding (5 senses). Rule out medical issues if in doubt.
Suicidal thoughts: ask directly if they’re thinking of harming themselves. Stay with them, remove means if safe, and contact help (U.S. call/text 988; use local crisis lines elsewhere).
Listen nonjudgmentally, validate feelings, avoid minimizing, and encourage professional support.

Legal and Ethical Considerations: Consent, Good Samaritan Laws, and Documentation

Obtain consent when possible; implied consent applies if unresponsive or unable to decide.
Good Samaritan protections often cover lay rescuers acting in good faith within their training; laws vary by location.
Respect privacy. Document care factually and objectively.

How to Document an Incident: What to Record and How to Communicate Handover

Record: date/time, location, patient details (age/sex if known), mechanism of injury/illness, findings (DRABC, vitals), care provided, times (CPR started, AED shocks, medications given), allergies/medications, witnesses, and patient statements. During handover, concisely share this information and give written notes if available.

Preparedness and Practice: Drills, Refreshers, and Certification Options

Practice builds confidence. Refresh skills annually or per certificate requirements. Consider courses from the American Red Cross, American Heart Association, St John Ambulance, or your local accredited provider. Learn where nearby AEDs are located and log emergency numbers into your phone.

Common First Aid Myths vs. Evidence-Based Practices

Do not put anything in a seizing person’s mouth; you can’t swallow your tongue.
Do not apply butter/ointment/ice to burns; use cool running water and cover.
Do not tilt the head back for nosebleeds; lean forward and pinch.
Do not induce vomiting for poisoning.
Tourniquets, when applied correctly for life-threatening bleeding, save lives.
Do not suck, cut, or tightly tourniquet snakebites; immobilize and seek urgent care.
Do not use raw meat on bruises or black eyes; use cold packs.
Hydrogen peroxide can damage tissue; prefer clean running water or saline for wound irrigation.

FAQ

How deep should I push during adult CPR?
- At least 2 inches (5 cm) but not more than 2.4 inches (6 cm), at 100–120 compressions per minute with full chest recoil.
Should I do back blows or abdominal thrusts for a choking adult?
- Either approach can work. Many guidelines support 5 back blows followed by 5 abdominal thrusts, repeating until relief. Use chest thrusts for pregnancy or obesity.
Can I give someone with a stroke aspirin?
- No. Call emergency services immediately and keep the person NPO. Aspirin may be harmful in hemorrhagic stroke; imaging is needed first.
How long do I hold an epinephrine auto-injector?
- Follow device instructions; many modern devices recommend about 3 seconds, while some older ones suggest up to 10 seconds.
Is it safe to use an AED on a wet person?
- Yes—quickly dry the chest where pads will go, remove from standing water, then apply pads. Do not use in an explosive/flammable environment.
When should I use a tourniquet?
- For severe, life-threatening bleeding from a limb that doesn’t stop with direct pressure and hemostatic dressings. Apply 2–3 inches above the wound, avoid joints, and note the time.
What should I do for a minor burn blister?
- Do not pop it. Keep it clean, dry, and covered with a non-stick dressing. Seek care if large, very painful, or signs of infection develop.
