In an emergency, by calling 911 you will be linked to a professionally trained dispatcher. They will be more likely to identify your location when you call 911 than if you call a routine phone number. The dispatcher will then ask you questions designed to get the appropriate resources to you. They are also able to provide you instructions on performing basic medical care if necessary.
Call 911 sooner rather than later!
Many conditions such as heart attack and stroke require treatment as soon as possible. The longer you wait with these conditions, the more damage is done.
Keep a personal medical information file and a copy of your ECG.
Ask you doctor to provide you a copy of your electrocardiogram (ECG) and keep it somewhere accessible. Update this every time you get a new ECG. Many persons have ECG tracings that differ from other people but are "normal" for them. When treating you, paramedics may acquire a new ECG. By having an previous one to compare, paramedics and doctors may be able to see important similarities or changes between the two that they otherwise could not. This can help in making critical treatment and transport decisions.
