CareFusion T-Bird VS, VSO2, AVS, and AVS3
CareFusion · Model T-Bird VS, VSO2, AVS, and AVS3
The TBird Series provides the platform for all upgrades and future enhancements. The TBird AVS/VSO2/VS Series is an advanced ventilatory system. It is designed to move seamlessly with your patient throughout the entire acute care environment, Emergency Room to Operating Room to Patient Room. The TBird employs an advanced turbine delivery system in a compact, durable and lightweight package, TBird series provides uninterrupted mechanical ventilation for your critically ill patient. No longer do you need to change ventilators as you move your patient to perform therapeutic or diagnostic procedures. Unlike most ICU ventilator systems that depend on an air compressor or a piped air system, TBird Series is self-contained. Its powerful turbine technology provides excellent gas delivery without a need for a compressed air source. This turbine, together with an internal and optional external battery, allows the system to be completely independent and mobile. The TBird Series incorporated important safety features like Apnea backup ventilation automatically activates whenever patient apnea is detected. The internal battery provides emergency power during temporary power outage, or battery power during short duration transport. An optional external battery provides additional backup and power for longer transports. The front panel locking mechanism prevents accidental changes to control settings during movement. The TBird Series is designed with the user in mind. The pressure manometer bar graph displays real time pressure readings as well as high and low pressure alarm settings. Its color-coded controls and displays are easy to read and set. Central control knob provides one-button operation. Upgrades can be completed in just minutes by simply changing a Configuration Memory Card. Accommodating numerous mounting options as in a stationary or transport stand, tabletop or nightstand the TBird Series flexibly adapts to the situation. The Seamless Solution® for critical care. The TBird Series offers it all: performance, mobility, flexible mounting, and safety. It is the first and only ICU ventilator designed to take your patient seamlessly through the critical care environment.
Key tips
- ·Never disable a low-pressure/circuit-disconnect alarm while troubleshooting - silence it, don't disable it.
- ·Verify the O2 supply source and pressure before assuming an internal fault.
- ·Circuit type must match the patient population (adult/pediatric/neonatal) - a mismatched circuit invalidates delivered volumes.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Exhalation valve leak / failure
HighSymptoms: Low exhaled tidal volume, high leak alarm, inability to maintain PEEP.
Root cause: Diaphragm/valve degraded by secretions and cleaning cycles.
Flow / pressure sensor drift
MediumSymptoms: Inaccurate delivered volume, false volume/pressure alarms.
Root cause: Sensor contamination or aging of differential-pressure transducer.
Compressor / turbine failure
HighSymptoms: Unable to reach set pressure, low-flow alarm, loud noise.
Root cause: Worn bearings or failed blower motor.
Patient circuit leak
LowSymptoms: Leak alarm, low circuit pressure, volume loss.
Root cause: Disconnected or punctured patient circuit / humidifier.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily pre-use check: self-test, circuit integrity, alarm function
- ·Scheduled circuit and inspiratory filter replacement per manufacturer interval
- ·Flow and pressure sensor calibration verification
- ·Battery load test and runtime check
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Exhalation valve leak / failure
- Confirm the presentation - typically low exhaled tidal volume, high leak alarm, inability to maintain PEEP - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: diaphragm/valve degraded by secretions and cleaning cycles.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the exhalation valve assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
