It is intended to be operated by qualified medical personnel under the direction of a physician. • When the ventilator is connected to a patient, it is recommended that a trained clinician be in attendance at all times to take prompt action should an alarm or other indication of a problem occur. I 4.4.1 Ventilator Setup Assemble the ventilator system as described in Section 4.2, page 4-1. If using a Bird blender, attach the air and oxygen hose assemblies to the appropriate gas sources. If required, turn supply sou_rce valves open and check supply pressure. If using a humidificatio_L device to humidify the inspired gas, follow the manufacturer's operating instructions. If using an external power supply, connect the electrical AC power adapter to a properly grounded electrical outlet. Turn unit ON by switching the Mode control from the OFF po:sition to the applicable ventilation mode. 4.4.2 Description 4.4.2.1 of Ventilator Modes Control Mode All parameters of the delivered breath are controlled by the ventilator. The breath is initiated according to the Breath Rate control. Gas is then delivered to satisfy the :requirements of the Flow and Inspiratory Time or Tidal Volume settings. The sensitivity control is non-operational in the Control mode. 4.4.2.2 Assist/Control This mode allows the delivery of either a Controlled or an Assist/Controlled breath type. In effect, the patient is allowed to augment breath rate, but not flow or tidal volume/ inspiratory time. When this mode is selected, a visual indicator will light notifying the user that the patient trigger function is active. In the Assist/Control mode, the patient is able to initiate an Assist/Controlled breath if both of the following conditions exist: • The ventilator is not currently in inspiration minimum exhalation phase, and; 4-6 or the Section 4.4: Start-Up Instructions (continued) • The patient inspiratory effort exceeds the Sensitivity trigger setting. After the initiation of a breath, gas is delivered to the patient in accordance with the Control settings. The patient is not permitted to augment the flow in this mode. 4.4.2.3 SIMV In the SIMV (Synchronized Intermittent Mandatory Ventilation) mode, all control parameters are used, with PEEP and Sigh as optional controls. Depending on the control settings, ventilation can be totally patient controlled, or totally machine controlled with varying degrees of ventilator support between spontaneous breaths. There are two (2) types of breath periods in SIMV, both defined by the Breath Rate control. They are Spontaneous Breathing present, and Spontaneous Breathing not present. • Spontaneous Breathing is present: An "assist window" is opened at the beginning of a breath period. If a patient effort is detected (defined by the Sensitivity control), an Assist/Controlled breath is delivered in accordance with the ventilator settings. The patient is then allowed to breath spontaneously for the remainder of the breath period. At the beginning of the next breath period, the assist window is reopened. If patient effort is detected, an Assist/Controlled breath is delivered and the cycle repeats. • Spontaneous Breathing is not present: Following a complete breath period wherein spontaneous breathing is not present, at the beginning of the next breath period the ventilator will deliver a mandatory Controlled breath as determined by the ventilator settings. The assist window will then be immediately opened. If a patient effort is detected, an Assist/Controlled breath will be delivered. The patient is allowed to breath spontaneous for the remainder of the breath period. The next breath period will be as described in the "Spontaneous Breathing is present" paragraph. 4.4.2.4 CPAP Mode In CPAP mode, the patient is allowed to breath spontaneously over an elevated baseline pressure. All breaths are completely patient controlled. This mode is accessed by turning the Breath Rate control to "0" and adjusting the external PEEP valve to a level appropriate for the clinical situation. 4-7 nJfAml IIl,, flllllr SECTION 4.0: TRANSPORTOPERATING INSTRUCTIONS VENTII LATOR Tidal Volume or Inspiratory Time and Flow should be adjusted to appropriate levels for adequate minute ventilation should the patient become apneic and the ventilator reverts to Apena Back-Up ventilation. 4.4.2.5 CAL Mode NOTE: Prior to entering CAL Mode, the patient should be disconnected from the ventilator and the patient port should be open. Upon entering CAL mode a display test will activate, illuminating specific LEDs. This function allows the user to verify the operation of membrane switches and associated LEDs. These LEDs will be Illuminated: ®PEEP Not Set • Apnea • Battery Low/Fail • External • Disconnect • Power • External Power (If Present) • All segments of the Airway Pressure Bar Graph Power Fail Membrane switches, when pressed, will cause the associated LED to illuminate. Switches that have associated variable controls or alarms Display when the of the control can through its range will display the value on the Monitor switch is pressed. The range and operation be checked by rotating the associated control after the switch is pressed. In CAL Mode, the ventilator will monitor the airway pressure transducer output for a maximum of 3 seconds. If the measured reading is within +4 cmH20 of 0, the unit will store this offset and will add or subtract it from the pressure reading during normal operation to obtain corrected pressure. The unit will display PASS to indicate that the calibration has been successfully completed, and the unit can be returned to normal operation. If the measured reading is greater than +4 cmH20, the unit will sound an audible alarm and flash FAIL in the LED display. The unit will not store this vallue, and if returned to normal operation the unit will not apply an offset to the pressure transducer signal. Causes for CAL. failure are excessive transducer drift and/or patient port not open. 4-B Section 4.4: Start-Up Instructions (continued) 4.4.2.6 OFF Setting When the Mode Control is in the OFF position, all controls, settings and alarms, except the Ventilator Inop Alarm, are deactivated and are rendered non-operational. To stop operations of the Avian Transport Ventilator, turn the Mode Control to the OFF position and press the Alarm Silence/Reset button. The visual inoperative light will continue to flash for approximately 30 minutes. 4.5 APNEA BACKUP VENTILATION This is an automatic function of the Avian Transport Ventilator. If the time between patient initiated breaths exceeds the 20 second Apnea Interval, the ventilator will automatically revert to the Assist/ Control mode of ventilation. An audible alarm will sound, and the visual Apnea Alarm indicator will flash. The breath rate will be 12 BPM. Apnea Backup Ventilation can be terminated by clearing the Apnea Alarm with the Alarm Silence/Reset button. The Apnea Backup Alarm is not mutable. 4.6 CLINICAL OPERATION 4.6.1 OF CONTROLS Mode Adjust the Mode selection control to the appropriate Control, Assist/Control, SIMV, or CPAP. 4.6.2 Inspiratory NOTE: Time/Tidal position for Volume Volume Cycled ventilation is the default form of ventilation. If the ventilator has been turned off, it will always revert to Volume Cycled ventilation when turned on. This is a multiplexed control that allows for direct setting of Tidal Volume for volume cycled ventilation or Inspiratory Time for time cycled ventilation. Selection of Volume cycled ventilation or Time cycled ventilation is made by depressing the Tidal Vol., or Insp. Time button. 4-9 A!J, iA al k,aliW SECTION 4.0: TRANSPORT OPERATING INSTRUCTIONS VENTI LATOR Once a selection is made (Tidal Vol. or Insp. Time), a transition phase is initiated, and the setting for the new type of ventilation will flash in the monitor window. During this transition phase, the ventilator will continue to ventilate the patient based on the former type of ventilation and at the former setting. The operator can adjust the new setting to the desired level. The new type of ventilation the following two actions: A) must be activated Pressing the Display button Volume) a second time. by performing one of for that control (Insp. Time or Tidal In this case, the value displayed in the monitor window cease flashing and will be displayed continuously. will or B) Adjusting the new setting for the new type of ventilation (Insp. Time or Tidal Volume), then adjusting the setting of, or pressing the Display button for another parameter on the ventilator (High Pressure Limit, Low Peak Pressure, Breath Rate, Flow, Manual PEEP Ref., MAP, PIP or Paw) In this case, the value for the selected parameter (High Pressure Limit, Low Peak Pressure, Breath Rate, Flow, Manual PEEP Ref., MAP, PIP or Paw) will be displayed in the monitor window. NOTE: • 4- 10 To activate the new form of ventilation under Section 4.6.2.B, an adjustment must be made to the new type of ventilation (Insp. Time or Tidal Volume) before adjusting the setting of, or pressing the display button of the listed parameters. In order to activate the newly selected form of ventilation, the operator must perform one of the actions outlined in Section 4.6.2. A or B. Failure to do so will result in the ventilator continuing to operate under the previous settings and previous type of ventilation. If, during the transition phase, the new setting will cause an inverse I:E ratio state, the ventilator will alternately flash "XXX" and "-IE" with "XXX" representing the Tidal Volume or Inspi_ratory Time setting. An audible alarm will be sounded if the new form of ventilation is activated in this condition. Section 4.6: Clinical Operation of Controls (continued) Should the operator wish to revert to the original form of ventilation during the transition phase, this can be done by depressing the display button for the original form of ventilation and following the same procedure outlined in Section 4.6.2. A or B. NOTE: 4.6.3 The Tidal Volume and Inspiratory Time controls are completely independent and do not correspond to each other. Breath Rate Adjust to the appropriate setting to establish the minimum machine breaths per minute. 4.6.4 number of Flow Adjust to the appropriate setting to establish the peak level of gas flow during a machine controlled and/or assisted breath and for Apnea Backup Ventilation. 4.6.5 Sensitivity Adjust to the appropriate level to determine the threshold level at which an assisted or a spontaneous breath will be initiated. 4.6.6 PEEP/CPAP PEEP is provided by a removable PEEP valve located at the patient valve. Adjust the PEEP valve to establish the baseline pressure for all breath types. 4.6.7 Manual PEEP Reference An external PEEP valve is used to establish elevated baseline pressures on the Avian Transport Ventilator. As stated in Section 3.2.5 on page 3-4, the ventilator is PEEP compensated. The level of PEEP set at the external PEEP valve is automatically recognized by the ventilator through the monitoring of the airway pressure. This information, used in conjunction with the Sensitivity setting, determines the level at which an assisted or spontaneous breath is triggered. The level of PEEP read by the ventilator for triggering assisted and spontaneous breaths can also be set manually via the Manual PEEP Reference function. 4-11 _j ArB _ _W 4f,,llliv-,,mllV SECTION 4.0: TRANSPORT OPERATING INSTRUCTIONS VENTILATOR i By depressing the Manual PEEP Reference button, an LED indicator is illuminated and the current level of PEEP measured by the ventilator is displayed in the monitor window. The display will read "A XX" where "A" indicates that the unit is automatically measuring the PEEP level set at the external PEEP valve, and "XX" is the value of PEEP the ventilator is measuring. Holding the button depressed for longer than 3 seconds will cancel this automatic function and initiate scrolling of the display from 0 to 20 cmH20. Releasing the button will freeze the display at the current setting, and the ventilator will use this value as its reference level of baseline pressure for triggering assisted and spontaneous breaths. The LED indicator will remain lit for as long as the Manual PEEP Reference function is active. To deactivate the Manual PEEP Reference and return to the automatic measurement of PEEP, depress the button and keep it depressed until the LED displays an "A O'. Releasing the button at this point reactivates the automatic PEEP reference function. 4.6.8 Sigh ON/OFF Depress the Sigh button to deliver a Sigh breath in the next breath cycle. An LED will light indicating that Sigh has been activated. A sigh breath will continue to be delivered once every 100 breaths or 7 minutes, whichever comes first, regardless of breath type. Sigh can be deactivated by depressing the Sigh button again, at which point the LED indicator will extinguish. 4.6.9 Manual Breath Depress this button to deliver one machine controlled breath in accordance with the current Flow and Inspiratory Time or Tidal Volume settings. A manual breath will not be delivered if activated during an inspiratory or minimum exhalation phase of a breath cycle of any breath type. 4.6.10 Pressure Relief Valve Turn the control knob clockwise (increase) or counterclockwise (decrease) to set the appropriate maximum allowable pressure in the patient circuit. This function can be used as an added safety feature to the High Peak Pressure Alarm. 4-12 5/97 Rev. D Section 4.6: Clinical Operation of Controls (continued) To use the Pressure Relief Valve as an added safety feature set the control 5 - 15 cmH20 (or according to hospital protocol) above the High Peak Pressure Alarm. This can be accomplished by attaching a Bird test lung (P/N 04845 or equivalent) to the patient circuit and turning the High Peak Pressure alarm to MAXIMUM (100 cmH20). Set the Pressure Relief Valve by depressing the Peak Inspiratory Pressure monitor button (PIP) and viewing the peak inspiratory pressure in the monitor window. Once the desired pressure level is achieved, adjust the High Peak Pressure Alarm 5 - 15 cmH20 (or to hospital protocol) below the pressure level of the Pressure Relief Valve. 4.7 WARNING CLINICAL OPERATION • ! 4.7.1 OF ALARMS It is the responsibility of the clinician or user to establish and monitor the appropriate alarm settings for each patient and mode of ventilation. High Peak Pressure Adjust to an appropriate setting higher than the peak pressure reading on the Monitor display to establish the High Pressure limit, above which an audible alarm will sound, inspiration will be terminated and exhalation will begin. This alarm is active for all breath types. NOTE: 4.7.2 The alarm limit is automatically increased by 1.5 times the display setting (up to 100 cmH20 ) during the delivery of a Sigh breath. Low Peak Pressure Adjust to an appropriate setting lower than the peak pressure reading on the Monitor display.

The lower ambient pressure at altitudes above ground level will cause the air to assume a larger volume. In other words, the actual volume delivered by the ventilator at altitudes above ground level will be greater than the tidal volume displayed on the unit. The actual volume delivered by the Avian Transport Ventilator can be calculated from the displayed tidal volume and pressure altitudes as shown in the Volume vs. Pressure Altitude Chart, Figure 4.1 on page 4-17. The Volume vs. Pressure Altitude Chart, Figure 4.1 on page 4-17 can be used to determine the tidal volume corrected for altitude. For example, if the Avian Transport Ventilator tidal volume is set for a 600 ml breath, at 6000 feet pressure altitude (1), the actual tidal .volume is determined by following the volume-pressure line. In this case, the 600 ml setting will deliver tidal breaths of 702 ml (2). If a 500 ml (3) tidal volume breath is desired at 8000 feet pressure altitude, then the ventilator should be set to deliver 404 ml (4). Care must be taken in determining the altitude in a pressurized aircraft since the cabin altitude is usually significantly lower than the flight altitude. The correction should be for the ambient altitude (pressure) where the Avian Transport Ventilator is used. 4 - 1F; Figure 4.1: Volume vs. Pressure Altitude Chart Figure 4.1 VOLUME NOTE: VS PRESSURE The Volume estimation altitudes. verified ALTITUDE vs. Pressure of various CHART Altitude changes Chart is provided in volume This chart is an approximation through a volume monitoring at various and volume as an levels of should be device. 2000 1900 .............................................................................. 00 1 1500 1200 _ = 1100 1000 900 800 -_ 700 6oo 50O 400 300 200 _ -._-'''_"-=" ,.,..--..- --=--. ---'_'-- "'--"-'-"'=""- 100 ""--'_"_ ,_ .=.._ -,,_= .-=-, .=..,._, -__..J_ _ _ ..,,.,-=- ........................................................ 0 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 1000011000 12000 13000 14000 15000 Pressure Altitude (feet) 4-q7 A!al !l I. flllW SECTION 5.0: TRANSPORTCLINICAL TROUBLESHOOTING VENTILATOR ! 5.1 INTRODUCTION This section consists of the Operator • WARNING. 5.2 Troubleshooting Chart.

The unit can operate from a wide range of DC and AC power sources, and requires a gas source at 40 to 60 PSI. The electronic control system is microprocessor based, and interfaces to the pneumatic ventilation system through a series of solenoid valves and a pressure transducer. The ventilator uses an exhalation valve and PEEP valve to complete the ventilation system and can also be equipped with an external air/ oxygen blender to provide variable oxygen concentrations. The following theory of operation described in Section 7.2 refers to the Pneumatic Schematic, Figure 7.1 on page 7-7. 7.2 THEORY OF OPERATION 7.2.1 Gas Inlet and Pressure Conditioning Air, oxygen, or blended gas from an external blender at 40 to 60 psig is connected to the ventilator 02 DISS gas inlet port. The gas flows to the PRESSURE REGULATOR where it is regulated clown to 30 psig. This provides a stable pressure supply to the remaining flow control system and insures that the delivery of tidal volumes and demand "flow is unaffected by inlet pressure variations. 7.2.2 Main Flow Control System Gas then flows to the MAIN SOLENOID VALVE, which controls the flow of gas for controlled and assist controlled breaths. At the start of inspiration, the valve opens and gas flows through the FLOW CONTROL VALVE which throttles the flow to the desired level. The FLOW CONTROL POTENTIOMETER is attached to the FLOW CONTROL VALVE poppet and senses the valve position. This information is used by the microprocessor to calculate tidal volume. Flow continues through the CHECK VALVE and out the inspiratory leg of the patient circuit to the patient. At the end of inspiration, the MAIN SOLENOID VALVE closes and stops the gas flow. 7-I A!HA D=flIEIF SECTION 7.0: TRASPORT OVERVIEW OF SYSTEM OPERATION VE NTI LATO R 7.2.3 Exhalation Valve and Control System When inspiratory flow is present as described in the previous section, a slight pressure drop exists across the CHECK VALVE. The upstream elevated pressure is fed to the EXHALATION VALVE balloon through the exhalation valve drive line that closes the EXHALATION VALVE at the beginning of inspiration. The balloon ihas an advantageous area ratio with the seat that, coupled with the elevated pressure, holds the EXHALATION VALVE closed during the inspiratory phase. When inspiratory flow is stopped, the exhalation balloon pilot pressure is bled off through the ORIFICE. A removable spring loaded PEEP valve can be attached port of the EXHALATION VALVE if PEEP is needed. 7.2.4 to the outlet Demand System When a spontaneous breath is triggered, the DEMAND SOLENOID VALVE opens and gas flows through the valve and the DEMAND ORIFICE where it is throttled to 60 LPM. Gas then flows out through the inspiratory leg of the patient circuit to the patient. Since the flow bypasses the CHECK VALVE, the exhalation balloon drive pressure does not rise, leaving the exhalation valve open. Excess flow not demanded by the patient flows out of the EXHALATION VALVE. Demand flow stops when airway pressure rises above the reference baseline. 7.2.5 Pressure Relief Function/Anti-suffocation Valve The pressure relief valve acts as a redundant safety feature or can be used to deliver pressure limiting breaths by establishing the maximum pressure in the patient circuit. If airway pressure exceeds the PRESSURE RELIEF VALVE setting, gas is vented to the room and the pressure is held constant at this level. When the inspiratory phase is complete or in case of a malfunction, the ventilator flow is shut off. In case of a ventilator failure or insufficient ventilatory support, patient can breathe directly from room air through the ANTI SUFFOCATION VALVE. 7-2 the Section 7.2: Theory of Operation (continued) 7.2.6 Airway Pressure Transducer Pressure at the patient airway is measured and converted to an electrical analog signal by the AIRWAY PRESSURE TRANSDUCER. This pressure is used for the bar graph display, breath triggering, and the pressure alarms. 7.3 ELECTRONIC 7.3.1 CIRCUIT DESCRIPTIONS Power Supply Board 7.3.1.1 Overview The power supply has four basic functional sections: Input power conditioning, battery charger, charger bypass power, and output voltage regulation. The schematic of this circuit board is found in Section 9.0, Figure 9.5.1 on page 9-27. 7.3.1.2 Input Power Conditioning External input power is applied through a bridge rectifier that allows application of a DC voltage without regard to polarity. AC voltage is also acceptable because a rectifier rectifies the AC. A capacitor provides the necessary filtering. The input can be DC voltage, (11 to 30 VDC), or an AC Voltage, (11 to 24 VAC, peak to peak). Fuse F700 protects against catastrophic failures such as shorted diodes. 7.3.1.3 Battery Charger The battery charger is a temperature compensated, current limited, dual-level float charger with a dead cell lockout. The charge cycle normally takes less than 24 hours. Input power from the external power source turns on the charger. The battery is charged at the trickle current rate until the battery terminal voltage exceeds the charge enable threshold of 3.96 volts. This protects the system against high charging current applied to a battery with a shorted cell, or a battery that is installed backwards. 7-3 AwE$ It, fllill f SECTION 7.0: TRANSPORTOVERVIEW OF SYSTEM VE NTI LATOR II NOTE: OPERATION Batteries that do not meet the charge enable criteria (3.96 volts) within 24 hours are probably defective and should be replaced. This condition will be indicated by the front panel Battery Low/ Fail Indicator being lighted while external power is present (even if the front panel Mode switch is in the OFF position). Once the battery voltage exceeds the charge enable threshold, the battery is placed in the bulk charge state. During the initial stages of charging a discharged battery, the ,charger may reduce the charge voltage to prevent the charge current from exceeding the 500 mA charge current limit. The charger will provide currents of zero to 500 mA as required and maintain the regulated standby float voltage. If the battery terminal voltage drops to 90% of the standby float level, the charger will switch back to the bulk charge mode. 7.3.1.4 Charger Bypass Power The Charger Bypass Power circuit provides power to the ventilator electronics without passing that energy through the battery charger control circuit. This helps improve accuracy of the battery charging process, which helps maximize the battery service life. 7.3.2 Main Printed 7.3.2.1 Circuit Board Overview The Main Printed Circuit Board contains the circuits used to operate and control the Avian Transport Ventilator.
