| Assistant commissioner of the charity Gerard Shortall said the incident showed how vital portable defibrillating equipment has become. |
| The machine automatically analyzes a victim's heart rhythm and signals the user to push a button to deliver a defibrillating shock if necessary. |
| Pacing must be turned off before defibrillating with a second defibrillator. |
| If it is needed, a defibrillating shock interrupts the potentially lethal rhythm and gives it the chance to start beating normally. |
| Both models' video and audio provide guidance on where to place the defibrillating pads and give step-by-step lifesaving instructions. |
| For such patients, a fracture that stops Fidelis from gently pacing the heart is an even more certain death sentence, Dr. Magovern said, than a fracture that stops it from delivering a defibrillating shock. |
