WELCH ALLYN, INC. · Model 901047
Welch Allyn CardioPerfect Workstation with PC-Based 12-Lead Resting Electrocardiograph, Noninterpretive, AHA ECG Cable, ABPM-7100S Ambulatory Blood Pressure System, PC-Based SpiroPerfect Spirometer
Intended use: An electrically-powered, noninvasive device designed to be worn by a patient (typically on the arm or wrist) during daily activities for 24-hour recording of blood pressure; it is not intended to detect cardiac arrythmias. The recorded measurements can be downloaded and analysed at a medical facility, typically using a computer with a dedicated software. The device typically incorporates display and controls and may include a cuff with connection tubing and/or calibration device.
Key tips
- ·Don't extend filter/tubing replacement intervals to save cost - this is an infection-control issue, not just a performance one.
- ·Flow accuracy drift is often the earliest sign of a failing sensor, well before an outright alarm.
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.
Oxygen concentrator sieve bed wear
HighSymptoms: Low O2 purity, alarm.
Root cause: Zeolite sieve exhaustion.
Compressor fault
HighSymptoms: Low flow, overheat.
Root cause: Worn compressor.
Suction pump failure
MediumSymptoms: Low vacuum, no suction.
Root cause: Diaphragm/motor wear.
Humidifier element fault
LowSymptoms: No humidity, overheat.
Root cause: Heater plate failure.

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.
- ·Filter and tubing replacement
- ·Flow accuracy check
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Flow sensor calibration drift
- Confirm the presentation - typically readings out of spec, failed daily calibration check - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: sensor fouling or transducer aging.
- 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 sensor / transducer 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: Display / touchscreen fault
- Confirm the presentation - typically unresponsive screen, frozen UI - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: digitizer or display aging.
- 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 disposable mouthpiece / bacterial filter 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.
