  • Page 19: Installing The Flow Sensor

    Installing the flow sensor EVE measures pressure and flow via the flow sensor (PNT). The measurement is taken proximally between the Y-piece and the tube connector. For this purpose, a flow sensor head is fitted between the two parts. The diff erential pressure resulting from the flow sensor head‘s resistor is a measure of...

  • Page 22: Function Fields

    Function fields Values Pressing this function field opens the „Values“ sub-menu. This provides an overview of the measured values currently determined by the ventilator. The logbook data can be saved on the internal SD card.
  • Page 23 Function fields Limits Pressing the „Limits 1-3“ fields lets you view all the alarm limits and adjust them to the patient‘s needs. If limits are breached during the current ventilation, the corresponding parameter field turns yellow or red, depending on the alarm priority. 1 Name and unit 2 Upper limit Alarms...
  • Page 24 Parameters Pressing this function field opens a sub- menu with all configurable parameters and additional functions for the currently active ventilation mode. 1 Optionally selectable additional functions 2 Current ventilation mode indicator 3 Ventilation parameters To change a parameter, select the corres- ponding field.

  • Page 25: Graphic Display

    Graphic display Pressing the „Graph“ button opens the graphic display, which can be customized. The initial layout can be pre-configured in the system settings. Three different layout versions are available. 1 Display of three curves 2 Display of two curves 3 Display of one curve, loop or trend The top field of the graphic display always shows the pressure curve.
  • Page 26 Configuring the measurement curves Select a measurement curve on the display to change it. A window with all available measurement curves (volume, flow, CO and plethysmogram) opens. You can now select the desired option. For a better view, the measurement curves can be frozen on the display.

  • Page 28 Flow This sub-menu consists of functions to check and configure (as needed) the flow sensor and trigger. In addition, the following can be selected here: use of an expiration valve with either distal or proximal pressure measurement and use of either an emergency hose system or high flow nasal cannula for ventilation.

  • Page 29: Standby Mode

    Standby mode If the selftest is passed, the standby screen appears. Initially, it always shows the ventilation mode and settings for the most recent ventilated patient. To keep these settings, press the „Continue Ventilation“ field to activate ventilation. Press the „New Patient“ field to create a new patient.
  • Page 30 Using fast tracking keys The easiest way to start a new ventilation process is by using the fast tracking keys on the front panel of the ventilator. These provide a quick and easy way to select the default ventilation parameters for preterm infants and newborns, children and adults.

  • Page 31: New Patient

    New patient This menu lets the user switch between settings for preterm infants and newborns, children and adults. This selection corres- ponds to the function of the fast tracking keys. After selecting the patient type, the system suggests pre-configured ventilation with ventilation parameters adapted to the corres- ponding patient type.

  • Page 32: Ventilation Settings

    Ventilation settings Selecting the ventilation mode This example uses invasive PC-SIMV to describe the selection of the ventilation mode. Proceed as follows: Press the „Invasive“ field in the menu. All available ventilation modes are displayed. Select „PC-SIMV“ and press the „Next“ field.
  • Page 33 Ventilation settings Parameters The configuration menu for PC-SIMV opens. 1 Additional functions for the selected mode 2 Current ventilation mode 3 Configurable ventilation parameters Possible additional options for PC-SIMV (here PRVC and PSV) and tube compensation are listed on the left side. The relevant confi- gurable ventilation parameters are listed on the right side.
  • Page 34 Ventilation settings Setting parameter The selected parameter turns yellow. The value can now be changed using the control knob. Press the control knob or the „Confirm“ field to complete your entry. Proceed analogously to configure the other ventilation parameters. Press the „Confirm“ button to save the settings and return the ventilator to the „Standby“...
  • Page 35 Ventilation settings Setting parameter PRVC This option lets the user select a target volume that guarantees a tidal volume with minimum required pressure during breaths. Depending on the patient‘s spontaneous breathing efforts and lung compliance, the inspiration pressure varies with the intention to apply the selected tidal volume with the minimum required pressure.
  • Page 36 Ventilation settings Setting parameter CPAP PSV PSV is designed to support insufficient spon- taneous breathing. It combines the benefits of pressure-controlled ventilation with the patient‘s spontaneous breathing activity. The ventilator uses the selected trigger threshold to detect the patient‘s inhalation efforts and then triggers a mandatory breath using the selected pressure support (Psupp).
  • Page 37 Ventilation settings Parameter setting CPAP backup ventilation CPAP can be combined with backup ventilation. The user can set the maximum desired apnea duration in the „Apnea“ field. If there is no spontaneous breathing during this time, the ventilator begins mandatory ventilation using the preset parameters.
  • Page 38 Ventilation settings Tube compensation All invasive ventilation modes can be combined with tube compensation. This function lets you adjust the ventilation pressure to the resistance of the tracheal or endotracheal tube. Adjustable parameters: • Compensation (%) • Tube diameter (mm)
  • Page 39 Stop ventilation To end the ongoing ventilation and switch to Standby mode, press and hold the „On/Off/Standby“ button for 3 s. Pressing the button for another 3 s turns the ventilator off.
