If you had to dial 999 in an emergency for an ambulance do you think they would be able to help you.....? - cardiac ambulance

Until the ambulance?
IE: if someone has suffered cardiac arrest, or who have invented or deliver your baby would you be willing to answer questions and offer practical help to the patient arrived at the scene before paramedics?
Take advantage of the panic and hysteria from the outside, because they trained to deal with that, do you think could help the phone or send an ambulance and go to the next emergency?
