Acronym Drill

Every acronym your course expects you to recite. Say it letter by letter and reveal, or tap each letter to check, and mark yourself honestly.

The drill

34 acronyms. Choose which, pick a way through them, and go.

How do you want to drill?

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.
