CareFusion TBird Legacy
CareFusion · Model TBird Legacy
The Quality of Hospital Care in The Comforts of Home Sending a ventilator dependent patient home requires coordination among a group of dedicated professionals: pulmonologists, other specialists, durable medical equipment personnel, hospital administrators, respiratory therapists, nurses, and homecare providers including the patient's family. Family members will tell you; with the right piece of equipment, providing comfortable ventilation at home can be uncomplicated and dramatically improve the quality of life for their loved ones. Unfortunately, the limitations of most ventilators can make caring for homecare patients a real challenge. The TBird Legacy provides the solution for anyone who requires the quality of hospital care at home. Lightweight and compact in its design, the TBird Legacy was the first homecare ventilator to use a turbine, which provides the continuous flow needed for low Work of Breathing (WOB) and easy synchrony with the patient's efforts. The internal battery provides patients with unprecedented freedom and complete mobility. An optional external battery further extends the patient's range. The TBird Legacy is one of today's most dependable, high performance ventilators, for the homecare market. Designed with comprehensive features such as built-in PEEP, adjustable flow triggering and the synchrony of pressure support, TBird Legacy exceeds the expectations of professionals concerned with patient outcomes. Clinically proven to enhance patient comfort, pressure support greatly reduces the work of breathing as well as the time needed to wean users from the ventilator. Now with Pressure Control as a breath type, the Legacy offers even more flexibility in meeting the patient's needs and lowering the WOB. The re-usable internal exhalation valve allows for a simple and low cost breathing circuit. Reducing the already low cost of operation. Reliable and easy to use and maintain, the TBird Legacy supports the breathing demands of a wide range of patients, making it the homecare ventilator of choice for everyone concerned
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.
O2 blender / mixer fault
MediumSymptoms: FiO2 out of range, oxygen alarm.
Root cause: Failed solenoid or proportional valve in blender.

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.

- RECALL
The automated dispensing cabinet software update included a .dll file that is not compatible with MedBank Cabinet stations with MedCart Matrix drawers. The cabinet system will stop functioning (Matrix drawers will stop opening in the MedBank Application) leading to delay in access to medications or supplies needed in residential or procedural care facilities.
