1.Horizontal axis for respiratory rate (f) 2.Vertical axis for tidal volume (Vt) 3.Minute volume curve – see next page 4.Safety frame in which target point may move 5.Target point, formed by intersection of target tidal volume and target rate 6.Current patient values, formed by intersection of measured tidal volume and current respiratory rate ASV adjusts the settings to guide the patient’s current values to the target point. This may be achieved for spontaneous breathing or passive patients. When the patient condition meets the target, the patient is considered optimally ventilated according to ASV. It is not an indication of the patient’s clinical condition. 1

ASV focuses on simplification of mechanical ventilation. This means: 1. Eliminating separate modes for passive and active patients 2.Reducing controls relevant for CO2 elimination to just %MinVol 3.Adding direct access to controls relevant for oxygenation (PEEP/CPAP and Oxygen) ASV maintains an operator-preset minimum minute volume independent of the patient‘s activity. The breathing pattern (tidal volume, rate, and inspiratory time) is calculated, based on the assumption that the optimal breathing pattern results in: 1.The least work of breathing 2.The least amount of ventilator-applied inspiratory pressure
