Medtronic ManoScan ESO
Medtronic · Model ManoScan ESO
Procedure can be performed in 10 minutes or less and requires minimal specialized training Data is depicted in spatiotemporal plots, making study interpretation easier Enhanced sensitivity provides useful results that help support a confident diagnosis Complete physiological mapping of esophageal motor function from the pharynx to the stomach Enables easy location of respiratory inversion point and LES to further aid in the diagnosis of a hiatal hernia.
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.

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 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: Excessive noise / high electrode impedance / flat or noisy channel
- Check and re-prep the electrode sites; confirm impedances are balanced and low.
- Swap the affected leads and try different headbox / amplifier inputs.
- Run the amplifier calibration / bio-calibration signal.
- Address mains interference (route cables, confirm the ground / reference).
- Replace the lead set or the headbox / amplifier as isolated.
Symptom: Stimulator gives no or weak output (EMG / NCS)
- Confirm the stimulator settings and that intensity ramps.
- Swap the stimulator probe / bar electrode and its cable.
- Test into a saline / test load per the manual.
- Check the stimulator output on a second channel.
- Refer the stimulator output stage if a good probe still gives nothing.
Symptom: Amplifier not detected / recording drops / data gaps
- Reseat the amplifier-to-PC link at both ends.
- Restart the acquisition software and the amplifier.
- Try a different port / cable.
- Update the driver / firmware if indicated.
- Replace the link cable or refer the amplifier.
