CALL 999 - Use the hands-free speaker if possible.
START CPR - There's a "How To" guide in our Education Zone.
The 999 Operator will tell you where the closest defibrillator is.
Send someone else to retrieve this. Don't leave the patient. Don't stop CPR.
If there isn't one nearby the ambulance will bring one with them.
