"We may be able to make marginal increases (with the new procedure)," Turley said.
"One of the limiting factors is that most people who have cardiac arrest are quite elderly or have multiple medical problems in addition to heart problems that make it difficult to resuscitate them."
Special circumstances such as cardiac arrest related to automobile accidents, electrocution or pediatrics still may require a direct trip to the hospital.
Authority officials unveiled a ":20 for Life" logo, which represents the 20 minutes of uninterrupted chest compressions recommended for the best chance for survival.
An 8-inch vinyl decal bearing the logo will be placed on the back of Kanawha County ambulances to spread the message to the community.
Carolyn Karr Charnock, the authority's public relations director, designed the logo.
"I just batted around some ideas, and the logo showing 20 minutes has ticked stuck," Charnock said. "We want the message to stay out there -- not just announce that we're changing -- we want the community to be aware that this is a program that will save lives."
Mike Jarrett, authority safety officer, encourages people to enroll in public CPR classes.
"We want our community to know," he said. "We want CPR classes to be as common as walking down the street.
"We have public CPR classes that are available now every Friday. If we get on scene, and you've been doing CPR for five or 10 minutes, you've become the first first responder. Citizen responder is the term that came out of Sandy Hook. You're helping us."
The Kanawha County Commission is sending 23 members of its staff, including Commission President Kent Carper, to be trained on the CPR protocol. Carper also serves on the authority board.
"I know we are supportive of this initiative and feel like it will save lives," said Jennifer Sayre, Kanawha County manager.
