A proximal expiration valve is used only with the emergency hose system for adults. The distal expiration valve is used for all other hose systems. Carefully insert the expiration valve in the corresponding connection on the right side panel and allow to engage. Do not tilt the expiration valve or press it in with force. Danger of breakage! The distal expiration valve is connected directly to the expiration port and linked to the tube system. Installing the flow sensor Flow sensor connection with proximal expiration valve Flow sensor connection with distal expiration valve Turn the flow sensor measurement line connectors upward to prevent condensate from entering the measurement lines. 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 differential pressure resulting from the flow sensor head`s resistor is a measure of the volume flow. Separate flow sensors are available for adults and children. The flow sensor is connected between the expiration valve and the endotracheal tube (ETT). The images show the additional connection of a bacterial filter. Ventilation mode display This display indicates the current ventilation mode, the active additional functions, the patient type and the flow sensor type. Selecting a non-invasive ventilation mode causes the display to turn orange. In addition, the icon for non-invasive ventilation appears. 1 Flow sensor type 2 Icon for invasive ventilation 3 Additional function for ventilation mode 4 Ventilation mode 5 Patient type 6 Icon for non-invasive ventilation Selecting this field opens a ventilation menu where you can adjust the settings to the current ventilation scenario. Invasive ventilation mode Non-invasive ventilation mode Measured value display This display gives a quick view of the relevant measured values together with the alarm limits shown after the measured value. 1 Function field for toggling between the measured value display and the display of the active measured block 2 Time display 3 Measured value 4 Name of measured value including unit 5 Alarm limits display Five measured values are displayed. Three sets of 5 measured values each are available. Only one set can be displayed at a time. Use the function field to switch between the sets. 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. 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. Alarms The ,,Alarms" sub-menu shows the ,,Alarm History" and all measured values that are monitored by alarm limits. Pressing the ,,Alarm History" field or the alarm indicator opens a list of the seven most recent alarms. 1 Name and unit 2 Upper limit 3 Current measured value 4 Lower limit Parameters Pressing this function field opens a submenu 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 corresponding field. The field then turns orange. You can now change the value using the control knob. If additional functions exist for the currently active ventilation mode, these can also be activated from this menu. Press the ,,Confirm" field to save the new settings and close the sub-menu. 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. The remaining fields can be freely configured by selecting them. Configuring the measurement curves Select a measurement curve on the display to change it. A window with all available measurement curves (volume, flow, CO2 and plethysmogram) opens. You can now select the desired option. For a better view, the measurement curves can be frozen on the display. To do this, press the ,,Stop" field in the selection window. After activation, the measurement curves run until the end of the scale and are then frozen. This mode is ended by pressing the ,,Stop" field or automatically after 20 s have passed. System settings This lets you access the following sub-menus: Info Display Time Function 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. 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. To switch to Standby mode from a current ventilation process, press and hold the ,,On/Off/Standby" button for 3 s. 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. To prevent operator errors, the desired fast tracking key must initially be pressed for 0.5 s, after which it starts to flash green. Pressing the key again for 0.5 s will then start or switch to the selected ventilation mode. Fast tracking key assignment can be customized in the Setup menu. New patient This menu lets the user switch between settings for preterm infants and newborns, children and adults. This selection corresponds 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 corresponding patient type. Press the ,,Confirm" button to save the settings and return the ventilator to the Standby screen. You can now select the ,,Start Ventilation" field. Press the ,,Mode Settings" field to change the ventilation mode. 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. 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 configurable ventilation parameters are listed on the right side. After the user selects the desired PC-SIMV option, the corresponding ventilation parameters are displayed and can be adapted to the patient`s needs. 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" menu. Select ,,Continue Ventilation" to activate the ventilation. 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. Increase the upper pressure alarm limit to e.g. 40 mbar to avoid pressure limitation. Ventilation settings Setting parameter CPAP PSV PSV is designed to support insufficient spontaneous 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). With PSV enabled, the ventilator stores the inspiratory peak flow during inhalation. Expiration is initiated as soon as the flow has dropped to the previously set percentage for the inspiratory peak flow. The Expiration Trigger Sensitivity (ETS %) is used for this setting. In pure CPAP ventilation, the Pinsp setting acts as an parameter for Insp.-Hold. 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. The parameter settings for backup ventilation are comparable to PC-SIMV ventilation. 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) 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.
