The list
Open any one to read it before you drill it.
The Delta Model
The assessment model you are examined on. Same wording as your Field Handbook.
HEMPPAScene Survey
Keep yourself, your partner and your patient safe. It starts at dispatch, continues as you approach, and never stops.
- H
Hazards
Any danger to you, your partner, the patient or bystanders: fire, traffic, weapons.
- E
Environment
Surroundings and conditions: weather, lighting, confined space, indoors or out.
- M
MOI / NOI
Mechanism of Injury (trauma) or Nature of Illness (medical): it steers the whole assessment.
- P
Patient count
How many? It changes triage, resources and transport plans.
- P
PPE
Gloves, mask, eye protection, gown: chosen for the risk in front of you.
- A
Assistance / backup
Decide EARLY: fire, police, more medics, helicopter, hazmat, extrication.
PACERSGeneral Impression
The rapid patient scan you do from the doorway: sick or not sick, before you touch anyone.
- P
Position
Supine, tripod, fetal, slumped? Posture gives instant clues about distress, pain and LOC.
- A
Age & gender
Narrows the differential: elderly with stroke signs, teen with OD risk, middle-aged chest pain.
- C
Chief complaint (apparent)
What are they saying, or what do you see? Gasping, clutching the chest, or simply not right.
- E
Eye tracking / alertness
Tracking = awareness. Staring = altered LOC. Darting = anxious or hypoxic. Closed = GCS time.
- R
Respiratory distress
SOB, stridor, gurgling, accessory muscles, one-word answers: tells you if airway, BVM or O₂ is needed NOW.
- S
Skin signs
Colour, moisture, temperature. Pale, cool, diaphoretic, flushed, cyanotic: your first perfusion metric.
HEISTField Considerations
The decisions to make before you roll, while the scene is still yours.
- H
History from others
Family, bystanders, coworkers, fire, police: your verbal ECG. What happened? How were they before? Any meds, drugs, history?
- E
Early oxygen / oximetry
If PACERS showed SOB, stridor, altered LOC or abnormal work of breathing, delegate O₂ now. Do not wait for vitals.
- I
Interventions: SMR, deadly bleeds
If the mechanism suggests spinal risk, start or delegate spinal motion restriction right away. Control any deadly bleed now. Do not delay either to get set up.
- S
Scene distance / time
Minutes or miles from help? Long transport, remote scene, GPS and route: time is risk.
- T
Transport urgency / stability
Stable = full assessment, control the scene. Unstable = load and go, reassess en route.
