A screenshot of the Guiding Pad app. The left-hand side of the screen displays the American Heart Association (AHA) pediatric advanced life support (PALS) ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT) cardiac arrest algorithm. The current step (eg, determining the shockable status of the arrhythmia) of the resuscitation process is surrounded by a blinking red line. Past actions already accomplished are shown as shaded. At the top right-hand side of the screen, a color-coded title depicts the current step in progress. Below, four pulseless dysrhythmias are displayed; the provider selects the right one under consideration. At the bottom right-hand side, a footer helps to anticipate the next cardiopulmonary resuscitation (CPR) step. IO: intraosseous; IV: intravenous.
