Viasys Vela
Viasys · Model Vela
Impressive technology in a small package. Pediatric through Adult ventilation, a host of impressive features, all neatly packaged in a compact mobile ventilator. Patented turbine technology for optimized response times and impressive flow and pressure capabilities provide you with the power to support your most challenging patients. Improved patient-ventilator synchrony and low work of breathing are possible through highly responsive inspiratory flow support. Vela's reliable, robust platform, including proven turbine performance means reduced downtime and low operating costs. A patented exhalation valve, driven by a linear-actuated voice coil, Bicore(r) sensor technology and proven algorithms provide consistently accurate volume delivery. Precise monitoring is essential for clinical effectiveness and patient safety. Vela's six-hour internal battery and turbine technology provide independence from compressors and wall air for the ultimate in mobility and uninterrupted ventilatory support. Vela provides you with the flexibility and safety that you demand. Impressive standard features include a high pressure oxygen inlet with blender, a low pressure oxygen inlet with accumulator, integrated FiO2 monitoring and continuous display of delivered FiO2 with high and low alarm settings.
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.
Compressor / turbine failure
HighSymptoms: Unable to reach set pressure, low-flow alarm, loud noise.
Root cause: Worn bearings or failed blower motor.
Power supply / battery failure
HighSymptoms: Unexpected shutdown, persistent low-battery alarm.
Root cause: Aged internal battery or failed PSU.
Patient circuit leak
LowSymptoms: Leak alarm, low circuit pressure, volume loss.
Root cause: Disconnected or punctured patient circuit / humidifier.
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.
Symptom: Flow / pressure sensor drift
- Confirm the presentation - typically inaccurate delivered volume, false volume/pressure alarms - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: sensor contamination or aging of differential-pressure transducer.
- 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 flow / differential pressure sensor 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 graphical user interface may become slow in its response and in some cases non-responsive. Under some circumstances this situation may cause the ventilator to delay the annunciation of alarms.
