Sudden Cardiac Arrest

Sudden cardiac arrest – the leading cause of death in the United States!

Contra Costa Emergency Medical Services (EMS) believes that a community can improve survival from sudden cardiac arrest (SCA) when a comprehensive, community-wide, systems-based approach to the treatment of cardiac arrest is in place.

The cardiac arrest system of care is described on this webpage.

  • Our Goals


    A comprehensive countywide cardiac arrest system of care designed to increase:
    Recognition of sudden cardiac arrest,
    Bystander CPR rates,
    AED availability, readiness and utilization;

    To provide:
    Dispatch assisted CPR – decreasing the time to first compression,
    Quality CPR and resuscitative care, and
    Integrated post-cardiac arrest care
    Resulting in increase in survival!


    The Contra Costa Cardiac Arrest System will consist of a collaborative network of citizens (HeartSafe Communities), 9-1-1 prehospital providers, and hospital personnel who are able to identify victims of sudden cardiac arrest and rapidly care for them preventing sudden cardiac arrest from becoming sudden cardiac death.

  • Key Principles & Definitions

    Key Principles

    Rapid recognition and treatment of a victim of SCA is a key component to survival. Knowing the signs of sudden cardiac arrest -

    If someone collapses and is:

    • Not responding
    • Not breathing or only gasping

    Calling 9-1-1 – Acting in Time – beginning CPR and using an AED as soon as one arrives doubles the victims chance of survival.


    Sudden cardiac arrest: (Also known as cardiac arrest) is the abrupt loss of heart function in a person who may or may not have diagnosed heart disease. Sudden cardiac arrest occurs when the heart's electrical system malfunctions and the heart suddenly stops beating, often without warning.

    Sudden cardiac death: Sudden cardiac death can occur when someone in sudden cardiac arrest is not treated promptly.

    Cardiopulmonary Resuscitation (CPR): is an emergency procedure performed in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It is indicated in those who are unresponsive with no breathing or abnormal breathing.

    Automated external defibrillator (AED): a lightweight, portable device that delivers an electric shock through the chest to the heart. The shock can stop an irregular rhythm and allow a normal rhythm to resume in a heart in sudden cardiac arrest.

    Cardiac Receiving Center: A hospital designated by Contra Costa County EMS with cardiac capabilities, (cardiac catheterization, laboratory and/or cardiovascular surgery), designed to provide rapid intervention for SCA patients and integrated post-cardiac arrest care.

  • Background

    Heart disease – with its most common manifestation, sudden cardiac arrest – is the leading cause of death among adults in Western countries. Nearly 383,000 out-of-hospital sudden cardiac arrests occur annually, and 88 percent of cardiac arrests occur at home - half of these are sudden and unexpected. Many victims of SCA appear healthy with no known heart disease or other risk factors. Statistically speaking, if called on to administer CPR in an emergency, the life you save is likely to be someone at home: a child, a spouse, a parent or a friend

    Components of a Cardiac Arrest System of Care

    • HeartSafe Community partnerships to promote sudden cardiac arrest recognition and response by our citizens
    • Expeditious EMS dispatch and response
    • Pre-arrival Instructions by EMS dispatch to assist in providing bystander CPR to the victim – decreasing the time to first compression and utilization of nearby AEDs
    • PulsePoint – to bring nearby citizen responders to the victim to provide CPR
    • AED Link – to request trained AED responders to bring their AED to the victim of a SCA decreasing the time to the first shock – the one major factor in survival
    • Public Safety AED programs – providing rapid defibrillation
    • Pre-hospital patient assessment and high quality resuscitation
    • Communication with receiving facilities
    • Cardiac arrest centers to provide rapid, appropriate post arrest care
    • Cardiac arrest system of care post event analysis and review

    Early Action is Key:
    For the best chances of recovery, don't wait, call 9-1-1 immediately! Begin CPR and send someone to get an AED if there is one nearby.
    When an AED is available, turn it on and follow the prompts.

  • Public Education

    Know the Signs of Cardiac Arrest

    If someone collapses and is:

    • Not responding
    • Not breathing or only gasping

    If someone experiences these symptoms

    Call 911 Act In Time

    Begin Hands Only CPR;
    Use an AED as soon as one arrives

    Survivor Network

    If you have survived a sudden cardiac arrest or you are the spouse of a survivor – join us on the second Thursday of each month - Mended Hearts is dedicated to “Inspiring hope and improving the quality of life for heart patients and their families through ongoing peer-to-peer support”

    There will be educational presentations, time for questions to be answered and time to listen or share your experience with others.

  • Cardiac Arrest Receiving Centers

    A Cardiac Arrest Receiving Center is a hospital designated by Contra Costa County EMS with cardiac capabilities (cardiac catheterization, laboratory and/or cardiovascular surgery), designed to provide rapid, appropriate post arrest care.

    As of January 1, 2014, the following hospitals have been designated as Cardiac Arrest Receiving Centers in the Contra Costa County Cardiac Arrest System of Care:

    • John Muir Medical Center, Walnut Creek
    • John Muir Medical Center, Concord
    • Kaiser, Walnut Creek
    • San Ramon Regional Medical Center, San Ramon
    • Sutter Delta Medical Center, Antioch
    • Valley Care Medical Center, Pleasanton
    • Alta Bates Summit Medical Center – Summit Campus, Oakland

  • Cardiac Arrest System of Care Performance

    CPR Report

    Our cardiac monitors gather data on rhythms, compressions, ventilations, timing of shocks and other events. We can now create a CPR Report that summarizes these events. Feedback to crews in a timely fashion allows for post-event analysis - data, to improve care.

    We have set goals for compression rate and compression ratio (chest compression fraction).
    Compression ratio is greater than 80%
    Compression rate is to be between 100 and 120

    Contra Costa County Emergency Medical Services (CCCEMS) participates in CARES (Cardiac Arrest Registry to Enhanced Survival. CARES is a database developed by the CDC and Emory University that enables CCC EMS to perform internal benchmarking and improve the response to cardiac arrest by strengthening the chain of survival in our communities.
