Electrical exposure risk associated with hands-on defibrillation.
BACKGROUND The use of hands-on defibrillation (HOD) to reduce interruption of chest compression after cardiac arrest has been suggested as a means of improving resuscitation outcomes. The potential dangers of this strategy in regard to exposing rescuers to electrical energy are still being debated. This study seeks to determine the plausible worst-case energy-transfer scenario that rescuers mig...
متن کاملHands-On Defibrillation An Analysis of Electrical Current Flow Through Rescuers in Direct Contact With Patients During Biphasic External Defibrillation
Background—Brief interruptions in chest compressions reduce the efficacy of resuscitation from cardiac arrest. Interruptions of this type are inevitable during hands-off periods for shock delivery to treat ventricular tachyarrhythmias. The safety of a rescuer remaining in contact with a patient being shocked with modern defibrillation equipment has not been investigated. Methods and Results—Thi...
متن کاملHands-On Defibrillation—The End of “I'm Clear, You're Clear, We're All Clear”?
T he importance of closed-chest compression in maintaining at least a minimum of myocardial blood flow during cardiac arrest has been increasingly recognized. The adverse effect of interruptions of chest compressions on coronary perfusion pressure is immediate and important; Berg et al showed a 40% decrease in cumulative coronary perfusion after a 13-second pause in chest compression. The 2010 ...

متن کاملElevated Defibrillation Threshold: Are Defibrillation Vectors Important?
The evaluation of the defibrillation threshold (DFT) is common after the implantation of implantable cardioverter defibrillator (ICD) devices. The goal of this standard of care is to achieve successful defibrillation of ventricular fibrillation. In patients with elevated defibrillation thresholds, alternative techniques are required to correct the situation. We describe a case in which an uncom...
