Breas Vivo 40 System
Breas Medical AB · Model US
A portable, electrically-powered device intended to provide long-term alveolar support for patients who do not require complex critical care ventilation. It typically uses positive pressure to deliver gas to the lungs at normal breathing rates and tidal volumes through invasive ventilation (i.e., with an artificial airway); it may also be used non-invasively (e.g., with a mask). It includes a control system and alarms, and may include a built-in humidifier. Several methods of cycling and ventilation modes may be used. It may be line and/or internal/external battery-powered for use in the home or a healthcare facility (including ambulatory).
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not power on or unexpected shutdown
HighSymptoms: The ventilation & respiratory is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

- ·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
Error Codes
Extracted directly from this unit's own service manual.
Low Pressure AlarmA low pressure alarm will be given when the Vivo 40's pressure fails to reach the low pressure alarm limit for 15 seconds.
The Vivo 40 will continue to give breaths with the same settings.
High Pressure AlarmA high pressure alarm will be given when the Vivo 40's pressure exceeds 10 cmH2 O more than IPAP/IPAPmax, for 3 consecutive breaths.
The Vivo 40 will terminate inspiration from the first high pressure breath. The Vivo 40 will then continue to give breaths with same settings.
Low Volume AlarmA low volume alarm will be given when the Vivo 40's volume fails to reach the low volume alarm limit for 15 seconds (45 seconds after startup and after cancelling a high leakage alarm).
The Vivo 40 will continue to give breaths with the same settings.
High Breath Rate AlarmA high breath rate alarm will be given when the delivered breath rate exceeds the high breath rate alarm limit for 15 seconds.
The Vivo 40 will continue to give breaths with the same settings.
Low Leakage AlarmA low leakage alarm will be given when the measured flow is lower than the expected leakage flow at set pressure.
The Vivo 40 tries to continue delivering breaths according to settings.
High Leakage AlarmA high leakage alarm will be given when the measured flow exceeds the expected leakage flow at set pressure during more than 15 seconds.
The Vivo 40 tries to continue delivering breaths according to settings.
Low Internal Battery WarningA low internal battery warning will be given when the internal battery is the last power source, and it falls below the voltage warning limit. Under normal circumstances, the low battery alarm can be triggered prematurely by a sudden increase in flow, such as an excessive leakage, a large breath or a mask off event. If this should happen, restart the Vivo 40 on internal battery. If the low battery
If the low battery alarm persists, the internal battery needs to be charged.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Fails the pre-use self-test / circuit check
- Run the self-test with the exact circuit, filter and humidifier that will be used.
- Leak-test the circuit and the expiratory valve; fit fresh flow sensors and an O2 cell if due.
- Repeat the self-test and note which check fails.
- Calibrate the flow sensors and O2 cell per the manual.
- Remove from service and refer an internal pneumatic fault to the OEM / biomed.
Symptom: Delivered tidal volume / flow or FiO2 inaccurate
- Verify tidal volume and flow with a calibrated gas-flow analyser and FiO2 at the wye with an O2 analyser.
- Calibrate the flow sensors and the O2 cell.
- Inspect the inspiratory and expiratory valves / diaphragms.
- Check the air and O2 supply pressures and the inlet filters / water traps.
- Refer the blender / proportioning valve if the mix is still wrong.
Symptom: PEEP not held / high circuit-pressure or auto-PEEP
- Inspect the expiratory valve / diaphragm for wear or moisture and replace it.
- Check the exhalation path and the expiratory flow sensor.
- Confirm the circuit and water trap are not obstructed.
- Run the valve / compliance calibration.
- Re-verify PEEP against the analyser.
Symptom: Low-supply / O2 alarm or turbine / compressor fault
- Confirm wall / cylinder supply pressure and the inlet hose and filter.
- Check the internal blender / regulator.
- For a turbine unit, listen for turbine noise and check it can meet flow demand.
- Replace the O2 cell if the FiO2 reading is the issue.
- Refer the turbine / compressor for replacement if it cannot meet demand.
