• Details of what is wrong and what has happened
• The address where help is needed
• The phone number you are calling from

Once this information is given, appropriate help will start to be arranged. However, the control room personnel may need to ask some additional questions including:

• The casualty's age, sex and medical history
• Whether the casualty is breathing, conscious, bleeding seriously or has had persistent chest pain
• The type of injury and how the casualty was injured
  
• Asking these questions will not delay help being arranged but it enables the control room personnel to offer advice if needed and ensure the most appropriate assistance is provided.
  
  There are a number of things that you can do to help the ambulance crew before they arrive:
• If you are in the street, stay with the patient until the ambulance crew arrives and call back if their condition or location changes.
• If you are calling from home or work, get someone to open the doors and signal where the ambulance crew is needed.
• Lock away any family pets.
• If you can, write down the patient’s GP details and collect any medications that they are taking.
• Remember to stay calm
