DRAFT Comprehensive Fire Service Study MEDINA, MINNESOTA <br /> <br />Matrix Consulting Group Page 37 <br />For perspective, the following chart illustrates the survivability of cardiac patients related <br />to the time onset: <br /> <br /> <br /> <br />The graph illustrates the chances of survival of sudden cardiac arrest diminish <br />approximately 10% for each minute that passes before the initiation of CPR and/or <br />defibrillation. These dynamics are the result of extensive studies of the survivability of <br />patients suffering from cardiac arrest. <br /> <br />While the demand for services in EMS is wide ranging, the survival rat es for full arrests <br />are often utilized as benchmarks for response time standards as they are more readily <br />evaluated because of the ease in defining patient outcomes (a patient either survives or <br />does not). This research results in the recommended objective of provision of basic life <br />support within 4-minutes of notification and the provision of advanced life support within <br />8 minutes of notification. <br /> <br />Considering the response time continuum, the response time goal for emergency services <br />is to provide BLS within 6 minutes of the onset of the incident (including detection, <br />dispatch, and travel time) and ALS within 10 minutes. This is often used as the foundation <br />for a two-tier system where fire or other resources function as first responders with <br />additional (ALS) assistance provided by responding ambulance units and personnel. <br /> <br />2 Fire Suppression Services <br /> <br />The goal of fire suppression systems is to save lives and minimize property damage. <br />Every structure fire goes through the same process of development.
