Abstracts of Four Human Studies on the Effects of TASER Electronic Control Devices Presented At the Australasian College for Emergency Medicine Winter Symposium

Studies Find TASER Electronic Control Devices, Including XREP, Do Not Significantly Impair Breathing Nor Affect the Human Heart


SCOTTSDALE, Ariz., July 3, 2008 (PRIME NEWSWIRE) -- TASER International, Inc. (Nasdaq:TASR), a market leader in advanced electronic control devices, announced that four abstracts reporting on human testing on the safety of TASER(r) electronic control devices (ECDs) were presented at Australasian College for Emergency Medicine Winter Symposium 2008 during July 2-4 in Newcastle, New South Wales. The Australasian College for Emergency Medicine is an incorporated educational institution whose prime objective is the training and examination of specialist emergency physicians for Australia and New Zealand and the ongoing Maintenance of Professional Standards.

The four abstracts reporting data from human studies of TASER electronic control devices and their conclusions are:

The Effect of Cross Chest Electronic Control Device Exposure on Breathing.

"This study demonstrates that the cross-chest exposure does not significantly impair respiratory function."



   Donald Dawes, MD, Jeffrey Ho, MD and James Miner, MD. Hennepin
    County Medical Center, Minneapolis, MN.

The Effect of the eXtended Range Electronic Projectile (XREP) on Breathing.

"This study demonstrates that the XREP does not significantly impair respiratory functions."



   Donald Dawes, MD, Jeffrey Ho, MD, Jeremy Olsen, MD and 
    James Miner, MD. Hennepin County Medical Center, Minneapolis, MN.

Echocardiographic Determination of Cardiac Rhythm During Trans-Thoracic Wireless Conducted Electrical Weapon Exposure.

"Although motion artifact limited a few of the evaluations, we were able to document sinus rhythm in over half of the subjects and were able to obtain heart rates in all but three. In all but those three subjects, we saw no evidence of myocardial capture or arrhythmia during a 20-second trans-thoracic XREP exposure."



   Jeffrey Ho, MD, Donald Dawes, MD, Robert Reardon, MD, 
    Anne Lapine, MD and James Miner, MD. Hennepin County Medical
    Center, Minneapolis, MN.

Cardiac and Diaphragm ECHO Evaluation during TASER Device Drive Stun.

"We did not find a connection between measureable, worsening human physiology and ECD DS exposure. This work is consistent with previously reported findings of human ECD studies utilizing deployed probe methodology."
