Superior Result Oriented Medically Approved Drager Evita 2 for Spontaneous Breathing in Ventilation Therapy

Spontaneous breathing strategy  

One of Evita 2 ’s strengths is its implementation of our "Room to Breathe" concept. Spontaneous breathing reduces the risk of atelectasis and improves the ventilation/perfusion ratio by maintaining a higher functional residual capacity. BIPAPTM*/PCV+, the universal mode for ventilation and weaning, gives a patient the freedom to breathe spontaneously at any time. AutoFlow®, the next step in volume-oriented ventilation, encourages spontaneous breathing in all volume modes and another option, Automatic Tube Compensation (ATC), gives a patient the feeling of virtual extubation by eliminating the work involved in breathing with a tracheal tube.

The right mode for every patient
Since an Evita 2 can be used to ventilate neonatal, pediatric or adult patients, it is the ideal “workhorse” for everyday clinical routine. The wide range of patients covered also reduces the amount of staff training required and ensures a greater flexibility in the use of resources.

Two-in-one ventilation
Mask ventilation can assist the weaning process by reducing the reintubation rate or even preventing intubation in the first place. The option of mask ventilation (NIV) adds to an Evita 2 ’s versatility so an ICU only requires one device for conventional and non-invasive ventilation.

Everything in view
The Evita 2 provides patient and ventilator-related monitoring with user interaction reduced to a minimum. The high-resolution full-color screen displays comprehensive information on a patient’s status, always showing two ventilation curves and six monitored values, and the screen configuration can be customized to show the most important values for a particular ICU.

One knob, simplified settings
This ventilator has a clearly arranged front panel consisting of a monitoring screen and various setting soft keys. The rotary knob plays a key role. The active setting parameters are visible at a glance and changes can be made by the well-established “select-adjust-confirm” principle.

Ventilation at a glance
The principle of only showing the necessary parameters reduces the complexity of everyday monitoring. Additional functions are located in the various screen menus. The ventilator provides you with a full-text message in the event of alarms so you have a clear idea of the problem.

Simpler and speedier standard procedures
The Evita 2 contains numerous functions to speed up and simplify routine procedures. Start-up settings can be configured to specific ICU practices. Suction procedures are simplified with the touch of a button, the exhalation valve can be changed in seconds to minimize downtime and sensors are automatically calibrated daily. However, manual calibration is also possible without interruption to ventilation. All these functions assist in reducing time for standard procedures.
