Evaluation: Draeger Evita Infinity V500 Intensive Care Ventilator
December 16, 2015 | Evaluations & Guidance
- The Draeger Evita Infinity V500 is an intensive care ventilator—a critical life-support device that delivers positive-pressure breaths to patients who require total or partial assistance to breathe.
- This model can also be used as an oxygen (O2) therapy device, in which oxygen is delivered via an oxygen mask, hood, or nasal cannula to patients who can breathe on their own.
- Major device components and software:
- Infinity C500—The medical cockpit, or control and display unit, containing the control console and data monitor
- Evita V500—The ventilation unit, producing the artificial ventilation
- Trolley 2—The transport supply unit, consisting of a mobile cart to house the cockpit, ventilation unit, and gas supply unit, with mounting rails for ventilation accessories.
- Software features: Note: To classify ventilation modes, ECRI Institute uses the taxonomy created by Robert Chatburn (Chatburn et al. 2014, Mireles-Cabodevila et al. 2013). As such, all ventilation modes and mode adjuncts are described using this nomenclature. ECRI Institute defines an advanced ventilation mode as one with either an intelligent or optimal breath targeting scheme per the Chatburn taxonomy. For more information, see the sources listed in the References tab.
- AutoFlow—An additional setting that can be activated on all of the Draeger volume-control modes. When activated, this option changes the mode from a volume-control mode to a pressure-control mode, wherein pressure is gradually adapted to account for changes in compliance in order to administer the set tidal volume.
- Airway Pressure Release Ventilation with AutoRelease—A pressure-control ventilation mode that allows the setting of an inverse inspiratory/expiratory (I:E) ratio and permits spontaneous breathing. APRV allows the clinician to set a desired ratio of expiratory flow relative to peak flow. AutoRelease then controls the amount of time spent at the low-pressure component of APRV based on the patient's compliance and resistance changes (compared to a clinician-determined amount of time in normal APRV). Draeger's APRV with AutoRelease may help manage patients with changing lung compliance and/or airway resistance.
- Graphical display of lung mechanics: Smart Pulmonary View—A graphical display of the lung, showing lung mechanics as the patient breathes. This graphic illustrates diaphragm movement, airway resistance, and lung compliance. If selected, a plot of tidal volume versus respiratory rate illustrates spontaneous breathing in relation to mandatory ventilation. (This option is standard only in the United States.)
