9.3 Triage & Primary/Secondary Survey
Key Takeaways
CAB (compressions and AED) is the unresponsive/SCA path; ABC or catastrophic-hemorrhage-first (cABCDE) is used when airway trauma or massive bleeding dominates.
Primary survey is catastrophic hemorrhage, airway, breathing, circulation, disability (AVPU or GCS), and exposure—never a full orthopedic special-test battery on a downed athlete.
START (adult) and JumpSTART (child) sort multi-patient scenes into Red/Immediate, Yellow/Delayed, Green/Minor (walking wounded), and Black/Expectant; classic adult red flags are RR >30, CRT >2 seconds or no radial pulse, or inability to follow commands.
Secondary survey is SAMPLE history, a focused exam, and vitals after the primary survey is complete or after life threats are managed.
Stop the contest when the field is an MCI, an SCA, or an unsafe scene; transfer care to EMS with MIST or SBAR and complete incident documentation and debrief.
Quick Answer: After scene safety, triage severity (PA8 task 0302). Unresponsive collapse with agonal gasps = SCA until proven otherwise: CAB plus AED. Massive bleeding or airway trauma = stop the bleed and open the airway first (cABCDE). Never perform a full orthopedic exam before the primary survey. Multi-patient scenes (bleachers, bus) use START / JumpSTART colors: Red, Yellow, Green, Black.
The primary survey answers one question: what will kill this patient in the next few minutes? The secondary survey answers: what else is injured, and what is the history? Triage answers: who gets those surveys first when you do not have enough hands? Mixing those three jobs—especially starting a Lachman test on a silent, non-breathing athlete—is the Domain III fail the exam writers still use.
CAB Versus ABC (and Catastrophic Hemorrhage)
American Heart Association (AHA) adult basic life support for cardiac arrest uses C-A-B: compressions, then airway, then breathing, with an AED as soon as it is available. The 2010 AHA guidelines made that shift so that blood flow starts without a delay for two breaths; subsequent AHA updates have kept compressions and defibrillation as the SCA priorities. Agonal gasps are not effective breathing. A basketball player who collapses, is unresponsive, and is gasping gets CPR and an AED, not a prolonged pulse hunt and not a knee exam because “he grabbed his leg on the way down.”
ABC still matters when airway trauma or ventilation failure is the life threat: facial smash with blood in the airway, drowning (hypoxia first), hanging/clothesline, or anaphylaxis with stridor. Open the airway (jaw-thrust if spine is a concern), suction, insert an airway adjunct you are trained to use, and ventilate. Compressions without oxygen help less if the problem was never a primary cardiac arrest.
Catastrophic hemorrhage can kill faster than an unopened airway. On a trauma-dominant scene (open femoral bleed, amputation on an ATV trail, arterial spray on the mat), the field sequence is cABCDE:
- c — Catastrophic hemorrhage — direct pressure, wound packing, tourniquet high-and-tight on a limb.
- A — Airway — open, clear, maintain; protect the cervical spine when MOI warrants.
- B — Breathing — look, listen, feel; seal an open chest; support ventilation.
- C — Circulation — pulse, skin, remaining bleeders; prevent shock.
- D — Disability — AVPU or Glasgow Coma Scale (GCS); pupils; gross motor/sensory in the limbs.
- E — Exposure — remove enough equipment and clothing to find the hidden wound, then prevent hypothermia.
AVPU: Alert, responds to Verbal, responds to Pain, Unresponsive. GCS (E4-V5-M6, best 15): eyes 4/3/2/1 (spontaneous, voice, pain, none); verbal 5/4/3/2/1 (oriented, confused, inappropriate, incomprehensible, none); motor 6/5/4/3/2/1 (obeys, localizes, withdraws, flexion, extension, none). A falling GCS or a patient who is only P or U is a Red problem, not a “wait and see.”
Exam trap: doing a full orthopedic exam before the primary survey on a downed athlete. Special tests are a secondary or even a sideline tool after the athlete is breathing, perfusing, and neurologically accounted for.
Primary Survey, Then Secondary (SAMPLE)
Primary survey is rapid and repeatable. On a football player who does not get up:
- Scene already declared safer; gloves on.
- Unresponsive? CAB + AED while someone calls 911 per the EAP.
- Responsive but pale with a rapidly expanding thigh? Tourniquet / pressure, then airway and breathing.
- Helmet/shoulder pads come off only as needed for airway, CPR, or AED pads—equipment removal is a primary-survey decision, not a souvenir for the trainer’s bag.
- Disability: AVPU, “squeeze my hands / wiggle your toes,” obvious deformity that threatens the limb’s circulation.
- Exposure: look at the chest and abdomen for a hidden penetrating wound or flail segment the pads covered.
Secondary survey starts when life threats are managed or a second provider can do it without stealing hands from CPR. Use SAMPLE:
- S — Signs and symptoms (pain location, dyspnea, dizziness).
- A — Allergies (medications, latex, bees).
- M — Medications (including ADHD stimulants, insulin, inhalers, supplements).
- P — Past medical history (sickle cell trait, asthma, seizure disorder, cardiac workup, concussion).
- L — Last oral intake (for surgery risk and for hyponatremia/heat differentials).
- E — Events leading up (hit, collapse without contact, lightning, heat, pool).
Then a focused exam of the injured region and vitals: pulse, respiratory rate, blood pressure if you have a cuff, oxygen saturation, skin, and a repeat AVPU/GCS. Reassess after every intervention. The secondary survey is not permission to delay the ambulance for a complete ligament battery.
START and JumpSTART: Four Colors
When number of patients exceeds immediate resources—bleacher collapse, team bus rollover, scaffolding failure, lightning with several down—you triage, you do not provide one-patient ICU care to the first person who groans.
START (Simple Triage and Rapid Treatment), adults, classic RPM / 30-2-Can Do:
- Direct anyone who can walk to a green collection area (Green / Minor, walking wounded). They still get a later re-triage.
- Remaining patients: Respirations. Apneic → open the airway. Still apneic → Black / Expectant (or deceased). Starts breathing after airway → Red / Immediate. Breathing but respiratory rate >30 → Red.
- Perfusion: no radial pulse or capillary refill >2 seconds → Red.
- Mental status: cannot follow simple commands → Red. Passes RPM → Yellow / Delayed.
| Color | Name | Meaning | Field examples |
|---|---|---|---|
| Red | Immediate | Life threat now; minutes matter | RR >30, shock, obstructed airway that you just opened, uncontrolled hemorrhage, cannot follow commands |
| Yellow | Delayed | Serious but can wait hours | Isolated closed long-bone fracture, stable perfusion, follows commands |
| Green | Minor | Walking wounded | Abrasions, minor lacerations, anxiety, small-bone injuries in people who walked to you |
| Black | Expectant / deceased | Unlikely to survive with resources on hand, or not breathing after airway | Apneic adult after positioning; unsurvivable injuries when many Reds still need you |
JumpSTART is the pediatric adaptation (commonly taught for children about 1–8 years). Differences you must not miss: expected respiratory rate band is about 15–45; <15 or >45 is Red. An apneic child with a pulse gets 5 rescue breaths before you assign Black; if breathing returns, that child is Red. Mentation uses AVPU (P or U → Red). Do not START-tag a second-grader with adult RR >30 cutoffs.
Only life-saving interventions during the first pass: open the airway, tourniquet or direct pressure, maybe a needle decompression if you are trained and it is in protocol. Then move to the next patient. That feels wrong until you remember the silent non-breather behind the bleacher.
Stop the Contest, Hand Off, Document
Stop the contest when the playing surface is the emergency: SCA, a suspected spine injury occupying the field, lightning, a mass-casualty in the stands, a chemical or fire problem, or violence. Officials and administrators in the EAP exist so this is a medical time-out, not a debate. A locker-room mental-health emergency may not stop a game in the other gym, but it does activate the EAP addendum and a dedicated responder.
Transfer of care to EMS is a skill, not a shrug. Use a structured hand-off:
- MIST — Mechanism; Injuries found; Signs/vitals; Treatment given (including time of tourniquet, number of AED shocks, last GCS).
- SBAR — Situation; Background (SAMPLE highlights); Assessment (your working impression: SCA, hemorrhagic shock, suspected C-spine); Recommendation (what you need them to continue).
Stay and assist until they have enough hands, then document: times, findings, interventions, who called 911, who received the patient. NATA 2024 rec. 18 requires an incident report after EAP activation; rec. 16 a debrief to improve the plan; rec. 17 CISD after a catastrophic event. Memory fades; the record is what protects the patient and the next rehearsal.
Put the whole chapter in one sentence for test day: write and rehearse venue EAPs (0301), refuse to die on the approach (0304), then sort and survey life threats before ligaments (0302).
A basketball player collapses without contact, is unresponsive, and has occasional agonal gasps. The knee looks swollen. What is the correct first survey approach?
Perform a full orthopedic examination of the swollen knee first so you do not miss a ligament injury the coach saw on the way down.
Take a complete SAMPLE history from the coach before touching the athlete, because past cardiac history changes whether you start CPR.
Use an ABC sequence that begins with two rescue breaths and a long pulse check, because agonal gasps prove the athlete is breathing effectively.
Treat as sudden cardiac arrest: CAB—high-quality compressions and an AED as soon as it is available; agonal gasps are not effective breathing, and orthopedic tests wait until after the primary survey.
Bleachers collapse at a volleyball match. An adult who cannot walk has a respiratory rate of 36, a palpable radial pulse, and follows simple commands. Using classic START, which category do you assign on the first pass?
Red / Immediate, because adult respirations greater than 30 meet a START immediate criterion even if the patient can follow commands.
Green / Minor, because anyone who can talk is walking wounded.
Black / Expectant, because a bleacher collapse is unsurvivable until a physician declares otherwise.
Yellow / Delayed, because following commands always overrides respiratory rate in START.
You completed a primary survey on a single football player with a closed tib-fib deformity, intact distal pulses, and a stable airway. EMS is rolling onto the field. What is the most appropriate next step?
Wave the crew in with “he’s hurt, good luck” and walk to the next event so you are not late for the junior-varsity kickoff.
Give a structured MIST or SBAR hand-off—mechanism, injuries, signs and vitals, treatment, or situation, background, assessment, recommendation—then complete written incident documentation and a later debrief.
Delay transfer until you finish a complete ankle special-test battery and insurance paperwork on the logo.
Refuse to stop the contest because a closed fracture is never a reason to interrupt play, and skip documentation because EMS will chart everything.
