“Guiding Pad” screenshots. Two screenshot examples of the Guiding Pad app. The left-hand side of the screen displays the AHA pediatric advanced life support (PALS) ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT) cardiac arrest algorithm. The current step (e.g., 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. On the right-hand side of the screen, the sequence of actions to be taken (e.g., to select the right pulseless dysrhythmias under consideration [left screenshot]) are displayed in a stepwise manner to facilitate accurate progression along the algorithm. The current action (e.g., to resume compression and ventilation [right screenshot]) is brought to the attention of the provider by a red-box warning and requires validation by a simple click. Once completed, the next action will be to deliver the weight-based epinephrine dose automatically calculated by the app and then to prepare amiodarone). At the bottom right-hand side, a footer helps to anticipate the next cardiopulmonary resuscitation step. CPR: cardiopulmonary resuscitation; IO: intraosseous; IV: intravenous; PEA: pulseless electrical activity
