When you call an ambulance, a dispatcher will answer your call and ask for information about your emergency. They will then dispatch a team of paramedics and an ambulance to your location. Paramedics will assess your condition and provide medical treatment, such as first aid or CPR, if necessary. Depending on the situation, they may also transport you to a hospital for further treatment.
In some cases, the paramedics may be able to provide on-site medical care and transport you to a hospital in the same ambulance. In other cases, a separate ambulance may be dispatched to take you to the hospital.
