Seven Los Angeles International Airport (LAX) police officers have earned recognition for saving the lives of three passengers since 2003 through the use of automated external defibrillators (AEDs) as the passengers traveled through LAX.

Mayor Antonio Villaraigosa and Fire Chief William Bamattre presented Certificates of Commendation to Airport Police Officers William Handley, Vern Williams, Richard Taylor, Gregg Iwamiya, Tanansuk Chow, Thomas Dye and Sergeant Steven Zouzounis.

The officers were recognized for saving the lives of three cardiac arrest victims by using automatic external defibrillators, mechanical/electrical instruments used to apply an electrical shock to a person whose heart is in fibrillation, airport officials said.

The shock is intended to cause the heart to defibrillate and return to a more normal rhythm.

Villaraigosa and Bamattre used the officers’ City Council commendations to highlight a new public service announcement about the lifesaving utility of defibrillators.

LAX started installing defibrillators in terminals in 2003 and they are now in all LAX terminals. All airport police officers have received training in the use of external defibrillators.
