If it Is a genuine emergency, call 999 and don’t panic. Always call 999 if someone is seriously ill or injured, and their life is at risk. Once you are connected to an ambulance 999 operator or call handler, they will ask you a series of questions to establish what is wrong. This will allow them to determine the most appropriate response as quickly as possible.
Do not hang up. Wait for a response from the ambulance control room as they might have further questions for you. The person who handles your call will let you know when they have all the information they need. You might also be instructed on how to give first aid until the ambulance arrives.
