Phase one looked at subjects exposed to a TASER at rest, and phase two looked at subjects exposed to a TASER after vigorous exercise. Methods: This is a prospective controlled two phase trial investigated the effects of a single TASER exposure. As part of their police training, healthy law enforcement officers received a 5-second TASER electrical discharge. Measures followed before and for 60 minutes after a exposure included: minute ventilation (VE), tidal-volume (TV), respiratory rate (RR), end-tidal PCO2 (PETCO2), oxygen saturation (O2sat), heart rate (HR), blood pressure (SBP/DBP), arterialized blood for pH, pO2, pCO2, and lactate, and venous blood for bicarbonate, and electrolyte. Data were analyzed using a repeated measures ANOVA and paired t-tests. Results: VE, TV, and RR increased from baseline at 1-min post exposure. Blood pH decreased statistically, but clinically unimportantly, from baseline at 1-min post exposure. Blood lactate increased from baseline through 30 min post exposure. Bicarbonate decreased from baseline through 30 min post exposure. All of these measures returned to baseline levels. HR and SBP were higher before the TASER exposure than any time afterwards. All troponin I values were less than 0.2 ìg/L. Ventilation was not interrupted and there was no evidence of either hypoxemia or CO2 retention. Preliminary results from Phase 2 (n=22) indicate no significant differences between control and taser groups after exercise. Conclusions: A 5 s exposure of a TASER X-26 to healthy law enforcement personnel either at rest or following vigorous exercise does not result in clinically significant changes of markers physiological stress.  aTASER  aARMA NÃO LETAL  aENSAIO  aTHE EFFECT OF TASER ON CARDIAC, RESPIRATORY AND METABOLIC PHYSIOLOGY IN HUMAN SUBJECTS
