Yes. When you call 999 about a cardiac arrest, the emergency dispatcher can guide you through CPR step by step over the phone \u2014 even if you have never done it before and feel completely unsure. This is called dispatcher-assisted CPR or telephone CPR.
The dispatcher will ask you a few quick questions to confirm the person is in cardiac arrest, then give you clear, calm instructions on where to place your hands and how fast to compress. You do not need to remember anything in advance \u2014 just call 999 and follow what you are told.
Telephone CPR has been shown to increase bystander CPR rates and improve survival. Do not hesitate to call because you are worried about doing it wrong. The dispatcher is there to help you.
If someone else is with you, one person can stay on the phone with the dispatcher while the other does the compressions.
