CareFusion ReVel
CareFusion · Model ReVel
Integrating tools that help clinicians make safe predictive decisions with Spontaneous Breathing Trial (SBT), studies have found that patients who tolerate a SBT for 30-120 minutes were found to have successful discontinuation of ventilation at least 77% of the time1. Integrated Pulse Oximeter allows monitoring of patient’s SpO2 and pulse rate during transport or in lieu of central monitoring.
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.
Fails the pre-use / extended self-test
HighSymptoms: Self-test aborts with a diagnostic code, circuit-leak or compliance test fails, ventilator not released for use.
Root cause: Patient-circuit leak, an exhalation-valve / flow-sensor fault, or an internal pneumatic / electronic fault (see the diagnostic-code table).
Oxygen / air delivery or blender fault
HighSymptoms: FiO2 not matching the setting, low or high supply-pressure alarm, gas-mix alarm.
Root cause: Blender fault, a wall-supply / hose issue, or a failing internal compressor / turbine.
Flow / pressure sensor drift
MediumSymptoms: Monitored tidal volume, pressure or flow implausible, frequent nuisance alarms.
Root cause: Flow sensor(s) or the internal pressure transducers aging or contaminated.
Exhalation-valve fault
MediumSymptoms: PEEP not held, auto-PEEP, high circuit pressure, exhalation-valve alarm.
Root cause: Worn or wet exhalation-valve diaphragm / assembly.
Battery / power fault
MediumSymptoms: Short battery run time, will not ride through a power interruption, will not charge.
Root cause: Aged internal / external battery.

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
Error Codes
Extracted directly from this unit's own service manual.
Battery Empty (Bat Empty)A Battery Empty alarm (a fixed alarm) is generated when the ventilator is operating from the Removable Battery Pack and the battery charge level falls below the 5% charge threshold.
To avoid possible Vent Inop immediately insert a charged Removable Battery Pack or connect the ventilator to an external source of power.
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: Self-test / circuit test fails
- Run the extended self-test (EST) with the exact circuit that will be used, and note the diagnostic code.
- Look the code up in the service manual's diagnostic-code table and follow the sequenced repair actions.
- Leak-test the patient circuit, humidifier and water traps.
- Fit a fresh flow sensor and exhalation valve and repeat.
- Verify secure connections of all cables and modules; replace CPU / main boards only after all other remedies.
Symptom: FiO2 or supply-pressure fault
- Confirm the O2 (and air) supply pressures and hoses.
- Verify FiO2 with a calibrated analyser at the wye.
- Calibrate the O2 sensor / blender per the service manual.
- Listen for the internal compressor / turbine cycling correctly on air-supply loss.
- Refer the blender / compressor for service if the mix is still wrong.

CareFusion has identified a potential for damage to the power connector on the EnVe and ReVel ventilators due to misconnection by the operator. The input port on the ventilators must have the adapters correctly aligned to function properly. Incorrect alignment may cause the pins in the connector to bend, causing the PTV AC power adapter and/or PTV Auto Lighter Power Cord to be shortened, and pre
