Page 15: Chapter 1: Introduction
The AVEA has been designed to function using most commonly available accessories. It is easy to clean and its design does not allow liquids to pool on the casing, reducing the likelihood of fluid leakage into the body of the ventilator.
Page 16 When Artificial Airway Compensation is turned on, the ventilator automatically calculates the pressure drop across the endotracheal tube. The AVEA then adjusts the airway pressure to deliver the set inspiratory pressure to the distal (carina) end of the endotracheal tube. This calculation takes into account flow, gas composition (Heliox or...
Page 17 AVEA ventilator systems Chapter 1: Introduction Full range of Patient Size You can select a patient size of Adult, Pediatric, or Neonate. Once the selection is made, the ventilator offers only those parameters, which are available for your selected patient size.
Page 18 Heliox Delivery (Comprehensive only, option on Standard) Using patented “Smart” connector technology, the Comprehensive model AVEA can deliver Heliox blended gas instead of Medical air. By simply changing a connector on the back panel, the ventilator identifies the gas input and adjusts to accommodate the change.
Page 19 AVEA ventilator systems Chapter 1: Introduction WARNING Connection of a gas supply at the Helium-Oxygen mixture inlet that does not contain 20% oxygen can cause hypoxia or death. Although an 80/20 mixture of Helium and Oxygen is marketed as medical gas, the Helium/Oxygen gas mixture is not labeled for any specific medical use.

Installation Note: The AVEA Disposable Expiratory Filter / Water Trap is supplied non-sterile. It can be used as an alternative for the AVEA reusable filter assembly (reusable filter, a collector vial, a water trap, and a cartridge component). The AVEA reusable filter assembly is not required when using the Disposable Expiratory Filter / Water Trap.
Page 27 After you close the locking lever, the filter is ready for use. Figure 2–12: Completed installation of Filter / Water Trap combination WARNING Incomplete insertion of the AVEA Disposable Expiratory Filter may cause misalignment of the filter seal, which will result in patient circuit leakage. Note: The lever closes without great difficulty if the filter is fully inserted into the filter cavity.
Page 28 Chapter 2: Unpacking and Setup Operator's manual Drain Tube and Pinch Clamp. Inspect for any visible damage and make sure it is securely installed. Periodically inspect the filter-vial water level and empty it before it reaches the maximum-level line. To empty the fluid in the collection vial, press open the pinch clamp to empty contents of the collection vial into an appropriate receptacle.
Page 29: Additional Information
INSPECTION: Inspect for any visible damage to the plastic housing or the folded filter media before use. Discard if there is any damage. REPLACEMENT: AVEA Disposable Exhalation Filter, including the drain tube and the pinch clamp are single use items. Replace with a new unused filter at each circuit change.

Page 32 Attaching Flow Sensors The AVEA can accept either a hot wire or a variable orifice proximal flow sensor. These are in addition to the instrument’s internal inspiratory flow sensor and heated expiratory flow sensor. Three proximal flow sensors are available for the AVEA.
Page 33 Variable orifice flow sensors are also available on some AVEA models. The neonatal VarFlex flow sensor is compatible in neonatal and pediatric applications where the peak inspiratory flow rate is less than 30L/min and is not active in adult applications.
Page 34 Chapter 2: Unpacking and Setup Operator's manual Variable Orifice Flow Sensor 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. This is a locking connector. To attach, first pull back the plastic locking collar, then push firmly onto the ventilator receptacle.
Page 35 Figure 2–22: Attaching nebulizer tubing Note: 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.
Page 36 A proximal pressure sensor to monitor proximal airway pressure can be attached to the Comprehensive model of AVEA. On the Comprehensive AVEA the connector is labeled as Aux as shown in Figure 2–23 and is circled in purple. When active, this feature will display & alarm to proximal airway pressures.

Page 43 Setting up Independent Lung Ventilation (ILV) The AVEA has a 25 pin receptacle on the rear panel (Figure 2–33) to allow for Independent Lung Ventilation (ILV) .with another AVEA. The output for ILV provides a 5VDC logic signal synchronized to the breath phase of the master ventilator.
Page 44 To connect two AVEA ventilators together for independent lung ventilation function, the cable must be wired so that the ILV input (the slave) on one AVEA is connected to the ILV output (the master) on the other AVEA. As shown in Figure 2–33 below, the ILV slave is pin 18, and the ILV master is pin 6.

Page 94 Chapter 3: Ventilator Operation Operator's manual Airway Pressure Release Ventilation (APRV / BIPHASIC) APRV / BiPhasic is a Time Cycled Pressure mode in which the ventilator cycles between two different baseline pressures based on time, which can be synchronized with patient effort. Controlled ventilation can be maintained by timed cycling the transitions between baseline pressures.

Note: IF PSV level is insufficient to meet patient demand, premature termination of the breath may occur with auto- triggering.
Page 109 CAUTION If a proximal flow sensor is used it must be attached at both the patient wye and at the ventilator connection to ensure proper function of the AVEA. Note: To ensure adequate bias flow for inspiratory triggering the bias flow setting should be at least 0.5 liters per minute greater than the flow trigger threshold.

Page 114 Chapter 3: Ventilator Operation Operator's manual Note: To protect against larger changes in lung compliance, the machine volume should be set higher and Volume Limit should be added. Insp Rise The Inspiratory Rise setting controls the slope of the pressure rise during a mandatory breath. This control is a relative control with fast being a setting of 1, and slow a setting of 9.
Page 115 AVEA ventilator systems Chapter 3: Ventilator Operation Note: Should the patient’s inspiratory demand be sustained beyond the controlled inspiratory time plus the minimum expiratory time with the demand system turned off, auto-triggering or double triggering may occur. This is the result of the patient demanding more flow than available resulting in a breath trigger after the minimum expiratory time.
Page 116 Chapter 3: Ventilator Operation Operator's manual Vsync breath operation is as follows: When Vsync is selected, a decelerating flow, volume test breath to the set tidal volume with a 40 msec pause is delivered to the patient. The ventilator sets the target pressure at the end inspiratory pressure of the test breath or the first pressure control breath.
Page 117 AVEA ventilator systems Chapter 3: Ventilator Operation PSV Cycle Sets the percentage of peak inspiratory flow at which the inspiratory phase of a PSV breath is terminated.

You must select the size and type of balloon you intend to use before you will be able to conduct the Balloon Test.
Page 127 Before placing the balloon in the patient a balloon test should be performed. Connect the esophageal balloon extension tubing to the EPM panel on the AVEA as described in Chapter 2. Remove the new esophageal balloon from its package and connect it to the pinned connector on the patient end of the extension tubing.
Page 128 Chapter 4: Monitors, Displays and Maneuvers Operator's manual 3. Once placed using the above criteria appropriate balloon location can be confirmed by performing an occlusion technique. This requires that the airway be occluded and the esophageal and airway pressures compared for similarity. After the balloon has been inserted and turned on, the ventilator will fill the balloon to the appropriate level and begin monitoring data.
Page 129 AVEA ventilator systems Chapter 4: Monitors, Displays and Maneuvers MIP / P Maneuver Screen Figure 4–12: MIP Maneuver Settings The MIP (Maximum Inspiratory Pressure) / P maneuver measures the negative deflection in the pressure tracing during the patient’s active effort to demand a breath.
