30:2 Compressions-to-Ventilation ratio for face mask application (30:2 mode) or Continuous compressions and 9 asynchronous ventilations for advanced airway application (CCV mode) Chest compressions at 100 per minute Adjustable chest compression depth from 0 to 3.2 inches (0 to 8cm) provides the AHA required “at least 2 inches (5cm)” for adults or 1.5 inches (4cm) if needed Compressions are 50:50 systolic to diastolic ratio (50% compression length) Automatic Transport Ventilator (ATV) delivers 0 to 1 L tidal volume coordinated with compressions Able to switch from 30:2 to CCV mode without interruption
