Patients’ lung mechanics change constantly during ventilation. Clinicians, however, don’t always have the time to monitor and adjust settings for each patient, minute by minute and hour by hour. ASV helps by adapting to the changing conditions and needs of each patient, from intubation to extubation (Sulzer CF et al. Anesthesiology 2001;95:1339-45).
ASV delivers the optimal tidal volume safely at the lowest pressure possible, combining the benefits of pressure-controlled ventilation with a volume guarantee (Cassina T et al. J Cartiothorac Vasc Anesth 2003;17:571-75).
ASV optimizes levels of ventilatory support and CO2 removal allowing the clinician to concentrate on the patient rather than on the device.
ASV applies on a breath-by-breath basis an "assess, optimize and achieve" concept: - Assess breath by breath the patient's lung mechanics.
- Optimize breath by breath the tidal volume/respiratory frequency combination based on lung mechanics.
- Achieve optimum tidal volume/respiratory frequency by automatically adjusting mandatory rate and inspiratory pressure.
