AB  - Aim: To evaluate the hypothesis that using an automated external defibrillator (AED) with video telephony-directed cellular phone instructions for untrained laypersons would increase the probability of successful performance of AEDs. Real-time communication with visual images can provide critical information and appropriate instructions to both laypersons and dispatchers.Methods: A prospective observational study was undertaken. 52 public officers with no previous experience in the use of a defibrillator were presented with a scenario in which they were asked to use an AED on a manikin according to the instructions given to them by cellular phones with video telephony. The proportion who successfully delivered a shock and the time interval from cardiac arrest to delivery of the shock were recorded.Results: Placement of the electrode pads was performed correctly by all 52 participants and 51 (98%) delivered an accurate shock. The mean (SD) time to correct shock delivery was 131.8 (20.6) s (range 101–202).Conclusion: Correct pad placement and shock delivery can be performed using an AED when instructions are provided via video telephone because a dispatcher can monitor every step and provide correct information.
