Backwoods First Aid
This chapter is not a substitute for a wilderness first aid course — take one before you need one. It covers the highest-stakes situations a forager or backwoods traveler meets, anchored to Wilderness Medical Society (WMS) guidance. When in doubt: stabilize, keep warm (or cool), and get to professional care.
Scene safety and calling for help
Before touching a patient: make the scene safe (falling limbs, water, traffic, the thing that caused the injury). Then get help moving — send your exact location, number of injured, and what happened. In no-signal country, a whistle (3 blasts), signal mirror, and bright clothing are your call for help.
Severe bleeding — direct pressure first
For life-threatening limb bleeding: press HARD directly on the wound with the heel of your hand through cloth or gauze — your body weight behind it. Pack deep wounds with clean cloth if you can. Do not remove soaked dressings; add more on top.
- Keep pressure continuous — peeking restarts the clock.

Tourniquets — when pressure isn't enough
If direct pressure cannot control limb bleeding, place a WIDE band (improvised: 2+ inches — never wire or cord) 2–4 inches above the wound (not over a joint), tighten with a windlass (stick) until bleeding stops, lock it, and NOTE THE TIME on the patient's skin or the band. Do not loosen it in the field — that decision belongs to professionals.
- A tourniquet that doesn't stop the bleeding needs tightening or a second one above the first.
- Time-marking matters: write it where rescuers will see it.

Splinting fractures and sprains
Immobilize the joints ABOVE AND BELOW the injury with rigid material (sticks, trekking poles, rolled magazines) padded with clothing, and bind snugly — not tight enough to cut circulation. Check fingers/toes for warmth, color, and feeling before and after splinting. Sling the arm or buddy-tape the leg as needed.
- Pad all rigid edges.
- Recheck circulation after any swelling change.

Tick removal
Grasp the tick with FINE-TIPPED tweezers as close to the skin as possible and pull STRAIGHT up with steady pressure — no twisting, jerking, or squeezing the body. Clean the bite with soap and water or alcohol. Save the tick in a bag with the date in case symptoms develop.
- Do NOT burn it, smother it with oil/nail polish, or use bare fingers — all raise infection risk.
- Watch for expanding rash, fever, or joint pain for 30 days; see a clinician if they appear.

Hypothermia — the backwoods killer
Hypothermia kills in mild weather, not just blizzards — wet + wind + exhaustion is enough. Signs: uncontrollable shivering, then shivering that STOPS, confusion, clumsiness, drowsiness. Treatment: get the person out of wind and wet clothes, insulate from the ground, wrap in dry layers plus a vapor barrier (tarp, emergency blanket), and put heat packs or warm bodies at the ARMPITS, CHEST, and NECK — not hands and feet. Handle gently; give warm sweet drinks only if fully alert.
- No alcohol — it dilates vessels and accelerates heat loss.
- A hypothermic person who stops shivering is getting worse, not better.

Heat stroke — cool first, transport second
Heat stroke (hot skin, confusion, collapse — with or without sweating) is a race against organ damage. WMS guidance: COOL FIRST, TRANSPORT SECOND. Immerse the person in cold water (tub, stream, trough) if possible; otherwise douse continuously with water and fan aggressively. Ice packs to neck, armpits, and groin help. Stop active cooling if shivering starts; get to emergency care regardless — this is always a 911-level emergency.
- Heat exhaustion (heavy sweating, weakness, nausea, still thinking clearly) is the warning — rest, shade, fluids, and electrolytes then.
- Do not give fluids to a confused or unconscious person.

Making water safe
Boil: a rolling boil for 1 minute (3 minutes above ~6,500 ft / 2,000 m) kills bacteria, viruses, and Giardia. If you can't boil: filter (0.2 micron) plus chemical treatment, or chemical treatment alone with full contact time — iodine and chlorine dioxide both work when dosed right. Let silty water settle first and use the clear top.
- Never drink untreated backcountry water on the assumption it 'looks clean.'
- Chemical treatments don't kill Cryptosporidium reliably — filter or boil where it's a concern.
Severe allergic reaction (anaphylaxis) — VERIFY BEFORE PRINT
[Editorial note: the researcher flagged this section as not yet verified against current WMS guidelines — confirm against the originals before any print edition.] General guidance only: trouble breathing, throat/tongue swelling, widespread hives with dizziness, or collapse after a sting, bite, or food are emergency signs. Epinephrine auto-injector users should follow their prescribed plan and call emergency services immediately; a second dose may be needed after 5–15 minutes if symptoms persist. Keep the person lying down with legs raised (or on their side if vomiting), and do not leave them alone.
- Anyone who has had anaphylaxis before should carry TWO auto-injectors in the backwoods.
- Antihistamines are not a substitute for epinephrine in severe reactions.
