    7. 7 Ventilator Set-up

    8. 8 1. Connect to power source and turn on. Power switch on the back of machine.

    9. 9 After turning power ON Power source LED illuminates (if not plugged in will run off internal battery) Performs POST Begins operation with last used settings. A Flow Cal Alert is displayed in monitor window as reminder to perform manual FC Press MONITOR SELECT to clear display. Vent then displays the current Apnea Interval settings. Pressing MS again displays current Bias Flow

    10. 10 Vent Performance Check aka User Verification Tests Do before connecting to patient Press and hold down MONITOR SELECT button as turn the ventilator ON. Keep holding down Select until UVT ON appears (So if vent on already, turn off and back on). When you see UVT ON message and hear audible alarm ? Silence alarm Press MONITOR SELECT button again - see message REMOVE PT

    11. 11 Press MONITOR SELECT again to display tests 5 tests appear in order as the CONTROL KNOB is rotated: alarm, lamp, switch, filter, leak, and exit. Alarm test - Press MONITOR SELECT to start test. The audible alarm sounds. Press MONITOR SELECT again to silence alarm. exit test, and advance to next test. Lamp test checks the LEDs

    12. 12 Switch test check function of control panel. Pressing MS button should make SELECT appear in window. Press any front panel control and the name of the control should appear in the window. Filter test checks the turbine inlet filter. Activating this tests accelerates flow to 140 LPM and measures the pressure drop across filter. The message FILTER 4.5 P indicates the pressure and a P that the filter passed.

    13. 13 Leak Test Most important test. Can select it first by scrolling through with control knob. Before starting test block Pt wye. Press MONITOR SELECT to start test Vent holds a pressure of 60 cmH2O twice. If the difference between the two tests is < 6 cmH2O, the test passes. Press MS to exit test and advance to EXIT out of special function section.

    14. 14 After leak test Set Apnea Interval using Special Functions Set Bias Flow using Special Functions To access Special Functions - Press and Hold Control Knob until VENT SETUP appears in the monitor window. Accessing Special Functions does not interfere with ventilation.

    15. 15 Special Functions There are 7 chapters under Special Functions Vent Setup Group, Alarm Setup Group, Transducer Data, Transducer Test, Event Codes, User Verificiation Tests, Service Verification Tests. Vent Setup includes Bias Flow, and Control Lock. Alarm Setup includes apnea interval

    16. 16 Next after checking Bias Flow and Apnea Interval Set Over Pressure Relief valve - located lower right section of vent. Set High Pressure Alarm to 120 cmH2O Create high pressure in circuit (block pt wye) Adjust relief valve to the backup setting (~ 10 above high pressure alarm) Set mode Check volume of audible alarm (back panel)

    17. 17 Finally Set controls Set alarms

    18. 18 MODES Assist-Control in VC, PC and VAPS SIMV in VC, PC and VAPS Pressure Support Volume Assured Pressure Support (VAPS) CPAP

    19. 19 To set a mode press desired mode button (LED light flashes) & press again within 5 seconds to activate mode, otherwise the mode remains unchanged.

    20. 20 To set pressure control mode 1. Select A/C mode 2. Then push PC pad 3. Dial desired pressure. [To switch back to VC, turn Pressure Control pressure level to OFF.]

    21. 21 To add Pressure support 1. Select appropriate mode (SIMV or CPAP) 2. Push PS pad 3. Dial in PS setting

    22. 22 To set Volume Assured Pressure Support, Select A/C or SIMV mode, set VT, Peak Flow and Pressure Control level and push VAP button

    23. 23 VAPS for machine breaths only Will give a pressure breath that is flow cycled as long as inspiratory flow does not fall to Peak Flow setting before target tidal volume delivered. If flow falls to Peak Flow setting before target volume delivered, ventilator transitions to VC mode and delivers flow at the set peak flow until target tidal volume delivered.

    24. 24 VAPS

    25. 25 Ventilation Parameters

    26. 26 To set ventilation parameters. 1. Press desired parameter button & turn the control knob to change setting.

    27. 27 After setting parameters you can lock the control panel to prevent setting changes. 1. By pressing the control knob. 2. A light to the right of the knob will illuminate. 3. Press again to unlock

    28. 28 ALARMS

    29. 29 The main alarms to set on the TBird are: Apnea Alarm (10-60 seconds) Alarm Silence (lasts 1 minute) High pressure limit Low peak pressure Low minute volume High respiratory rate

    30. 30 To set alarms 1. Push the button for desired alarm 2. Turn the control knob to change the setting.

    31. 31 WAVEFORMS

    32. 32 The TBird has a optional Graphic monitor interface for viewing wave forms.

    33. 33 Special Functions These are accessed by pressing the control knob for 2 seconds. Clinical parameters found here include adjustment of bias flow & apnea period alarm. Bias flow can be adjusted from 10 20 LPM. Press control knob again to Exit.

    34. 34 Other Functions

    35. 35 Battery The battery lasts approximately for 1 Hour. Internal battery charges whenever vent plugged into AC source and vent turned off (standby). When power turned off, alarm sounds, press alarm silence. Flashing Vent Inop indicator continues to flash for several minutes (does not effect battery).

    36. 36 TBird VSO2 What the clinic has Similar to AVS but with less stuff (no NIF, Exp hold, VAPS or descending waveform)
