1. Concentration claim

In the first minutes, outcomes concentrate in getting help coming, CPR for cardiac arrest, and pressure or a tourniquet for life-threatening bleeding.

2. Hard anchors

AHA CPR facts. https://cpr.heart.org/en/resources/cpr-facts-and-stats. Immediate CPR can double or triple survival after cardiac arrest. Not a general airway claim.
Stop the Bleed. https://www.stopthebleed.org/. Direct pressure. Tourniquet for life-threatening limb bleeding. Packing where a tourniquet will not fit. Elevation is not the step.

2b. Field 80/20 examples

Approx % claim	Field	Source	Where
Double or triple survival	Cardiac arrest, immediate CPR	AHA	CPR section, narrowed
Intro 20/80 hedged	rule of thumb	prose	Intro

3. Original observation

A three-row do/leave table: course, pressure then tourniquet, a named caller.

4. Ignored majority

A kit never opened, a diagram searched during the event, elevation as the bleeding plan.

5. Composite policy

Scenario	Keep as Illustrative?
Bystander who lifted the leg and never called	Yes

6. Vital few

Scene safety and a named call
Chest compressions for suspected cardiac arrest, learned in a course
Direct pressure, then tourniquet for a limb that will not stop

7. Device budget

Template C. One table. One 8020 move. No step-by-step CPR recipe. No viz.
