Quick Reference

The mnemonics, sequences, and ranges you want at your fingertips. Always defer to your patrol’s current protocols.

Primary Assessment

Find and fix life threats, in order

X
eXsanguinating hemorrhage — control massive bleeding first
A
Airway — open and clear; jaw thrust if spine suspected
B
Breathing — rate, depth, effort; assist if inadequate
C
Circulation — pulse, skin color/temp/moisture, cap refill
D
Disability — AVPU, pupils, gross neuro check
E
Expose/Environment — see the injury, protect from cold

AVPU Scale

Rapid level of responsiveness

A
Alert — awake, oriented, interacting
V
Verbal — responds to voice
P
Pain — responds only to painful stimulus
U
Unresponsive — no response

SAMPLE History

Structured patient history

S
Signs & symptoms
A
Allergies
M
Medications
P
Pertinent past medical history
L
Last oral intake
E
Events leading up to the incident

OPQRST

Exploring a chief complaint

O
Onset — what were you doing when it started?
P
Provocation/Palliation — what makes it better or worse?
Q
Quality — sharp, dull, crushing, burning?
R
Radiation — does it move anywhere?
S
Severity — 0–10 scale
T
Time — how long, constant or intermittent?

DCAP-BTLS

What your hands look for in the exam

D
Deformities
C
Contusions
A
Abrasions
P
Punctures / penetrations
B
Burns
T
Tenderness
L
Lacerations
S
Swelling

Normal Adult Vital Signs

Typical resting ranges — trends beat single values

Respirations
12–20 breaths/min, quiet and effortless
Pulse
60–100 beats/min, strong and regular
Systolic BP
Roughly 90–140 mmHg
Skin
Pink (nail beds/membranes), warm, dry
Cap refill
Under 2 seconds
Pupils
Equal, round, reactive to light (PERRL)

Pediatric Vitals (approx.)

Faster is normal — know the shift by age

Infant (<1 yr)
RR 25–50 · HR 100–160
Toddler (1–3)
RR 20–30 · HR 90–150
Preschool (3–6)
RR 20–25 · HR 80–140
School age (6–12)
RR 15–20 · HR 70–120
Adolescent
RR 12–20 · HR 60–100

Shock: Early vs Late

Catch it while it's still treatable

Early
Anxiety, tachycardia, pale/cool/clammy skin, thirst, delayed cap refill
Late
Falling BP, weak thready pulse, altered mental status
Care
Control bleeding · supine · insulate above AND below · O₂ · NPO · rapid transport

START Triage

30 seconds per patient at an MCI

Walks
→ Minor (green), send to collection point
No breathing after airway opened
→ Deceased/expectant (black)
RR > 30
→ Immediate (red)
No radial pulse / cap refill > 2s
→ Immediate (red)
Can't follow commands
→ Immediate (red)
Everyone else
→ Delayed (yellow)

Hypothermia Stages

Core temp below 95°F / 35°C

Mild
Shivering, clumsiness, poor judgment, withdrawn
Moderate
Shivering slows/stops, confusion, slurred speech
Severe
Unresponsive, slow pulse/breathing — handle GENTLY
Care
Shelter · remove wet layers · insulate + vapor barrier · warm sweet drinks only if fully alert

RICES

Sprains, strains, and soft-tissue care

R
Rest
I
Ice (barrier between ice and skin)
C
Compression
E
Elevation
S
Splinting / support
