Phone Number. Thank You! Your question has been sent successfully. Quick view. Insert the completed cartridge assembly into the ventilator body as shown. Make sure it is completely seated in the well. Using an active humidifier, the adult patient circuit is set up as shown in figure 2. Attach your humidifier to the upright pole of the AVEA base. Adjust the height of the humidifier and the length of the humidifier tubing so that the tubing is relatively straight with no occlusions.
The setup for use with a passive humidifier or HME is per figure 2. The inspiratory limb of the patient circuit connects directly to the gas output of the ventilator. The AVEA can accept either a hot wire or a variable orifice proximal flow sensor. Three proximal flow sensors are available for the AVEA. This flow sensor is not active in adult applications.
A Hot Wire flow sensor attaches to the receptacle circled in light blue directly below the variable orifice flow sensor connection on the front panel. The receptacle is marked with the icon shown here. This is a locking connector. To attach, first pull back the locking collar, then push firmly onto the ventilator receptacle.
To disconnect, first retract the plastic collar then firmly pull the connector away from the ventilator. Do not pull up or down as this can damage the connector. Variable orifice flow sensors are also available on some AVEA models. Detailed information on the specifications of each flow sensor can be found in Appendix E: Sensor Specifications and Circuit Resistance. Variable Orifice sensors attach to the receptacle on the front panel of the ventilator circled in dark blue and marked with the icon shown here.
To attach, first pull back the plastic locking collar,. Then push the locking collar forward to lock the flow sensor in place. Fully retract the plastic locking collar before attaching these connectors. Failure to do this can cause damage to the connector. Attach the nebulizer tubing to the fitting at the bottom of the front panel as shown here. The fitting is marked with the icon shown here. To use the internal nebulizer, the AVEA must be connected to a high-pressure air source.
The nebulizer is not active while the AVEA is operating on its internal compressor. The ventilator incorporates an internal pneumatic compressor, which creates the drive pressure necessary to operate the nebulizer. The nebulizer requires an inspiratory flow rate of at least 15 liters per minute to activate and is flow compensated to maintain set tidal volumes. However, since flow from the internal nebulizer can vary, using the internal nebulizer may impact the tidal volumes delivered to the patient.
A proximal pressure sensor to monitor proximal airway pressure can be attached to the Comprehensive model of AVEA. In applications which generate high resistances within the breathing system monitored, Proximal Airway Pressure may be higher than set Inspiratory Pressure.
The connection intended for an esophageal balloon is circled in green at the top of the front panel as shown here. It is identified with the legend P ES. The connector is shown in figure 2.
To prevent the risk of excessive enclosure leakage current from external equipment attached to the RS, printer or video ports, the protective earth paths must be isolated to ensure proper connection. The AVEA has a standard 25 pin female Centronics parallel printer port for interfacing to an external printer. A SVGA output connector is provided to enable real time display of the screen from a separate external display device such as an LCD projector or remote monitor.
This output can be switched on and off on the utilities screen. This communication port is used for all serial communication from the AVEA. The oxygen sensor cell is located on the rear panel, between the two gas fittings. The oxygen sensor cable emerges from the rear panel directly above the sensor. Carefully align and then gently push the connector onto the oxygen sensor until it seats. When a good connection has been made, slide the protective cover down and push over the sensor.
There are two gas connections on the rear panel of the ventilator. The one on the left of the panel is for attaching the Air or Heliox gas source. Align the connector see figures 2. The fitting on the right of the panel is for attaching the Oxygen gas source.
Attach the Oxygen hose to the fitting on the right of the back panel see figure 2. If you have the upgrade for Heliox delivery, attach the Heliox hose. The air hose will not attach to the fitting designed for Heliox and vice versa. Allow 90 seconds for the accumulator to purge before initiating patient ventilation with Heliox gas. The fitting shown here is a DISS fitting. To change alarm sound levels depress and hold the increase or decrease soft keys until the desired level is reached.
The High and Low oxygen alarms can be disabled in the event of a failure of the oxygen sensor while the ventilator is in use. The oxygen alarms cannot be disabled while heliox is in use. Powering the ventilator off and back on again will automatically re-enable the oxygen alarms.
Although disabling the oxygen alarms will not effect oxygen titration an external analyzer should be placed in line in the breathing circuit until the oxygen sensor has been replaced. Default position is BTPS and should be used for all clinical applications. To enable Independent Lung Ventilation and define the Master and Slave ventilators, access the Utilities screen from the screens menu see figure 2. With both ventilators turned off, connect the ILV cable PN to the analog port of each ventilator.
Adjust all primary and advances settings as desired. Adjust all primary and advanced settings as desired. Each ventilator maintains independent settings for FiO2 during independent lung ventilation.
Close monitoring of set FiO2 on each ventilator is recommended. Confirm alarm settings on each ventilator. Each ventilator will alarm independently based on alarm settings established for that particular ventilator. Apnea ventilation on the Slave ventilator is driven by the apnea ventilation rate of the Master ventilator only.
The Slave ventilator will alarm for Apnea and begin apnea ventilation at its own active settings. This could cause damage to the ventilator. A specially configured cable is required for ALL features associated with this connector. The AVEA has a 25 pin receptacle on the rear panel see figure 2.
Table 2. This connector also carries the Analog Input and the Analog Output signals. As shown in figure 2. In addition, at least one of the analog grounds pins 5, 9, 10, 11, 12 or 13 must be connected. We recommend using a shielded cable. Connect an analog ground on Vent 1 to analog ground on vent 2 See figure 2.
At least one analog ground is required for safe and accurate signal output and input. One analog ground is sufficient for any and all of the other signals.
Touch the language box and use the data dial to select the desired language. Use the Accept key to accept the change. All text displayed on the LCD screen will automatically be translated to the set language.
For ease of use all languages appear in their native text in the text selection box on the utilities screen. Sets the number of consecutive breaths with an exhaled tidal volume below the Low Vte Alarm setting which are required to sound the alarm. The default is 3 breaths; the range is breaths. Configures the step increase used during the increase oxygen maneuver. Sets the amount of oxygen the ventilator will increase above the current set FiO2. The settings will be reset to default values when New Patient is selected in the set up menu.
Using the touch turn touch technique use the data dial to set the correct barometric pressure for the current altitude. Failure to properly set the barometric pressure can affect accuracy of some of the instruments monitoring systems. If the full-scale output of the device you are interfacing with is less than 1 volt, select the volt scale button. If it is 5V or less, select the volt range.
Analog Input is configured on the same connector as the ILV. The pin configuration for cables to use this feature is shown in figure 2. Pin configuration of the connector for attachment to your other device must be supplied by the manufacturer of that device.
All applications using this connector require specially made cables. This could result in damage to the ventilator. The analog output flow signal can be selected between Wye Flow calculated flow to the patient or Machine Flow the flow measured by the inspiratory flow sensor within the ventilator. The pin configuration for pressure, flow, volume and breath phase analog outputs is shown above. Default position is off. The AVEA can be connected to a remote nurse call system via the modular connector on the rear panel shown in figure 2.
The jack is configured to interface with normally closed NC, open on alarm or normally open NO, closed on alarm signals. Using the touch turn touch technique use the data dial to set the correct month, day and year prior to use of the ventilator. Using the touch turn touch technique use the data dial to set the correct time in hours and minutes prior to use of the ventilator. To power up the ventilator, connect the power cord to a suitable AC power supply and turn on the power switch located on the back panel of the ventilator as shown here.
If the protective ground is lost, all conductive parts, including knobs and controls, which may appear to be insulated, can render an electric shock. If the integrity of the external power earth conductor arrangement is in doubt, unplug the ventilator from the mains AC and operate it from its internal battery or the optional external battery.
The User Verification Test consists of the three following sub-tests and should be performed before connection to a new patient. Normal ventilation commences at the culmination of the POST.
During this test the ventilator will perform:. Although failure of any of the above tests will not prevent the ventilator from functioning, it should be checked to make sure it is operating correctly before use on a patient.
This test is run automatically and performs the following checks: Processor Self Check. The EST function is accessed from the Setup screen as shown here. A message will appear instructing you to remove the patient and block the patient wye. After confirming that the patient has been disconnected and the circuit wye blocked press the Continue Cont button.
The patient circuit compliance measurement and leak test are performed simultaneously with the oxygen sensor calibration. The maximum time for the EST is 90 seconds. To restart the EST at any time select the Cancel button to return to the set up screen.
Once the test is complete press the continue button to return to the set up screen. If you do not connect the ventilator to an oxygen supply, the O2 Sensor Calibration will immediately fail. To ensure proper calibration of the oxygen sensor, you should always perform an EST prior to conducting Manual Alarms Testing. Following each alarm verification test, ensure that the alarm limits are reset to the recommended levels shown in this chapter before proceeding to the next test. To perform the Alarms Test on the AVEA ventilator using default settings, complete the following steps A table describing the default settings for Adult, Pediatric and Neonatal patient sizes is included at the end of the Alarms Test section.
