Evone: Full respiratory control

Evone is the only commercially available ventilator applying FCV^® , directing both the inspiration and the expiration of an anesthetized patient requiring mechanical ventilation. Evone’s FCV^® ventilation mode is based on a controlled inspiration and expiration flow from a set PEEP to a set peak pressure and vice versa, relying on intratracheally measured pressures. The inspiratory flow is continuously controlled by advanced mass flow regulators; the expiratory flow is controlled by regulated suctioning. FCV^® ventilation needs a sealed airway to fully control the inspiration and expiration.

Evone’s FCV^® ventilation mode can be used with any adult endotracheal tube (single or double lumen, at least size 5 mm ID). This mode allows the use of Ventinova’s Tritube, an ultrathin endotracheal tube (outer diameter 4.4 mm) with an inflatable cuff to secure the airway.

Additionally, Evone has a (High Frequency) Jet Ventilation mode, which requires an open airway. Jet ventilation can be used as breathing support while emerging the patient from mechanical ventilation to spontaneous breathing. Therefore, Evone is able to fully ventilate in case of an obstructed (sealed) airway and an open airway.

 Features

• More efficient ventilation as compared to conventional Volume Controlled Ventilation (VCV) and Pressure Controlled Ventilation (PCV) protocols
• Increase alveolar aeration, lung recruitment and oxygenation in both healthy and diseased lungs
• Because FCV® gradually changes airway pressure and volume over time, this ventilation mode effectively reduces the net energy applied to the lungs as compared to both VCV and PCV
• When using Tritube, the patient can be liberated from ventilation using Evone’s jet ventilation mode with a deflated cuff, reducing cuff-related stimuli in the trachea.
• Patient ventilation independent of airway patency, this with either an obstructed (sealed) airway or open airway.

Applications

Evone can be used in the operating room and intensive care unit (ICU) in sedated patients under direct supervision. FCV^® enhances aeration of the lungs and maintains lung recruitment. Also studies show an increased ventilation efficiency, meaning a better oxygenation and CO₂ removal. Therefore FCV may be beneficial in patients prone to develop atelectasis or to desaturate during surgery. Successful use of FCV during single lung ventilation and in obese patients are described on our Evidence pages ‘Higher efficiency’.

In severely ill ARDS patients the higher efficiency together with its minimized energy dissipation, FCV^® may be considered as an option to allow adequate ventilation and to support the lungs to heal. The use of FCV® in ICU, in-vivo studies and theory are described on our Evidence page ‘lower energy’.

Evone, in combination with Tritube, is being used during a wide variety of surgical procedures. Especially during ENT/laryngeal surgery this combination offers several new surgical options for treatment. Our ventilation techniques FCV^® and EVA^® enable full ventilation through small bore lumen, providing adequate ventilation even in cases involving critically obstructed airways. In comparison to jet ventilation, it strongly reduces the risk on barotrauma. The use of FCV® during laryngeal /airway surgery is described on our Evidence page ’small lumen’.
