Datascope · Model 98XT
Automated, one-button start-up. Simple menu allows users to customize preferences. Automated printing of waveforms and patient data on alarm and at scheduled intervals. All keys on one keypad. Keypad and Display are detachable for mounting on bypass machine. On-keypad switching between direct and slave signals. Integral saline/transducer pole. Fully automatic condensate removal. Built-in service diagnostics. Special cables reduce noise from electrocautery and motion.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Balloon gas leak / autofill fault
HighSymptoms: Frequent autofill cycles, low helium alarm, loss of augmentation, gas-loss shutdown.
Root cause: Micro-perforation in the IAB catheter or a loose luer/safety-disk connection at the extension line.
Trigger loss / poor ECG or pressure signal
HighSymptoms: "Trigger not detected" message, erratic timing, pump switches to internal trigger.
Root cause: Worn skin electrodes, damaged patient ECG cable, or a slaved monitor signal that drops out.
Condensate / water accumulation in the pneumatic line
MediumSymptoms: Erratic augmentation, moisture in the extension tubing, autofill failures.
Root cause: Automatic condensate-removal system clogged or its drain reservoir full.
Internal battery will not hold transport charge
HighSymptoms: Short run time on battery, battery alarm during patient transfer, unit powers down off mains.
Root cause: Aged sealed lead-acid / Li-ion battery pack past its service life.
Compressor / solenoid drive fault
MediumSymptoms: Unable to reach set augmentation pressure, noisy pump, pressure-limit alarm.
Root cause: Worn compressor, sticking fill/vent solenoid valve, or a failing drive board.

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.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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: Repeated autofill and low-augmentation alarm
- Confirm the helium cylinder is open and above the minimum-pressure mark; swap in a full spare.
- Inspect the full pneumatic path - safety disk, extension line, catheter luer - for loose fittings and re-seat.
- Run the pump's leak / integrity self-test.
- If the leak localises to the catheter, treat the IAB as failed and coordinate catheter exchange with the clinical team.
- After repair, verify stable augmentation on 1:1 timing before returning to service.
Symptom: Trigger not detected / erratic timing
- Check ECG electrode contact and skin prep; replace dry or lifting electrodes.
- Inspect the patient ECG cable and the slaved-monitor cable for breaks; substitute a known-good cable.
- Switch trigger source (ECG to pressure, or direct to slave) to isolate the failing input.
- Verify the arterial pressure transducer is zeroed and the line is free of air.
- Confirm timing markers track the dicrotic notch before leaving the bedside.
