Standard first aid classes teach you how to keep someone stable until an ambulance arrives. Survival first aid teaches you how to keep them alive when you are the only ambulance.

If the grid falls, or you are deep in the wilderness, relying on bandaids and CPR is insufficient. The absolute most critical skill you can possess is the ability to stop massive bleeding (hemorrhage) within 60 seconds, as arterial bleeding can cause exsanguination before any other intervention matters.

The M.A.R.C.H. Assessment

Adopted directly from Tactical Combat Casualty Care (TCCC), the M.A.R.C.H. algorithm dictates the strict order of operations for saving a dying patient. Do not skip steps. Do not focus on a broken arm if their femur artery is bleeding.

• M - Massive Hemorrhage Identify and immediately stop life-threatening bleeding. Apply a CoTCCC-approved tourniquet "High and Tight" over clothing for extremity arterial bleeds. Pack junctional wounds (groin, armpits) with hemostatic gauze and hold immense pressure for 3 minutes.

• A - Airway Ensure the casualty can breathe. If unconscious, use the chin-lift or jaw-thrust maneuver. Insert a Nasopharyngeal Airway (NPA) if their airway is compromised but they still have a gag reflex.

• R - Respirations Check for tension pneumothorax (collapsed lung caused by penetrating trauma to the chest box). Seal chest wounds with a vented chest seal.

• C - Circulation Check for signs of shock and reassess earlier tourniquets to ensure they haven't loosened. Stop minor bleeding.

• H - Hypothermia / Head Injury Keep the patient warm. A trauma patient who gets cold will enter the "trauma triad of death" where their blood stops clotting. Wrap them in a mylar survival blanket immediately, even in warm weather,, to prevent shock-induced hypothermia.

Building a Proper IFAK (Individual First Aid Kit)

Do not buy pre-made kits from big-box stores unless they specify TCCC compliance. A proper trauma kit requires specific life-saving equipment that the 200-piece bandaid kits lack.
