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

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

Vent Performance Check akaUser 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

• 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

• 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
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 cmH2O, the test passes.
• Press MS to exit test and advance to EXIT out of
  special function section.

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
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
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
Finally

• Set controls
• Set alarms

18
MODES

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

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

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
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.

Flow falls to set Peak Flow before target volume
delivered, switches to VC

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

ALARMS
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
To set alarms 1. Push the button for desired
alarm 2. Turn the control knob to change the
setting.
31
WAVEFORMS
32
The TBird has a optional Graphic monitor
interface for viewing wave forms.
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
Other Functions
Insp hold press and hold button before start of
inspiration. Set pause time by pressing button
and turning control knob.
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
TBird VSO2

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