First Aid on Site — DRSABCD

The first minutes matter most. The DRSABCD action plan and the CPR numbers, in the order you do them — for the moment you hope never comes.
DRSABCD — the action plan
| D — Danger | Check the area is safe — for you, bystanders, then the casualty |
| R — Response | Squeeze shoulders, ask their name: 'can you hear me?' |
| S — Send for help | Call 000 (112 from any mobile). Send someone for the defib. |
| A — Airway | Open and clear the airway — tilt head, lift chin |
| B — Breathing | Look, listen, feel — is breathing normal? |
| C — CPR | Not breathing normally? 30 compressions to 2 breaths |
| D — Defibrillation | Attach an AED as soon as it arrives; follow the voice prompts |
CPR numbers
| Compressions to breaths | 30:2 (all ages) |
| Compression rate | 100–120 per minute |
| Depth (adult) | About one-third of chest depth (~5 cm) |
| Not trained / won't give breaths? | Compression-only CPR — and don't stop until help takes over |
