WELCH ALLYN, INC. · Model 901060
Welch Allyn Connex 6800 Vital Signs Monitor with Masimo SpO2, Masimo Acoustic Respiratory Monitoring (RRa), SureTemp Plus Thermometry, SureBP Non-invasive Blood Pressure, Pulse Rate, MAP, BP Averaging, Nurse Call, Four USB Ports for Accessories, Internal 802.11 a/b/g Wireless Radio; 100-240 V, 50-60 Hz AC, IEC Plug Type-B
Intended use: An electrically-powered device/device assembly designed for the continuous assessment of several vital physiologic parameters (e.g., ECG, blood pressure, heart rate, temperature, cardiac output, apnoea, and respiratory/anaesthetic gas concentrations) of one patient in intensive or general healthcare settings. It typically set-up by the patient bedside and often includes programmable alarms, portable radio transmitters, receivers, and antennas (telemetry systems) to allow monitoring during patient ambulation or transportation; it is not dedicated to neonatal use and is not intended to be worn on the body.
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
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.
Exhalation valve leak / failure
HighSymptoms: Low exhaled tidal volume, high leak alarm, inability to maintain PEEP.
Root cause: Diaphragm/valve degraded by secretions and cleaning cycles.
Flow / pressure sensor drift
MediumSymptoms: Inaccurate delivered volume, false volume/pressure alarms.
Root cause: Sensor contamination or aging of differential-pressure transducer.
Power supply / battery failure
HighSymptoms: Unexpected shutdown, persistent low-battery alarm.
Root cause: Aged internal battery or failed PSU.
O2 blender / mixer fault
MediumSymptoms: FiO2 out of range, oxygen alarm.
Root cause: Failed solenoid or proportional valve in blender.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Exhalation valve leak / failure
- Confirm the presentation - typically low exhaled tidal volume, high leak alarm, inability to maintain PEEP - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: diaphragm/valve degraded by secretions and cleaning cycles.
- 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 exhalation valve assembly 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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
A defective electrical component in the battery charging circuit in two lots of the ProBP 2400 may potentially cause an over-voltage battery charging condition when the device is connected to the external power supply/battery charger. This potential defect resides with the device, not the battery. The over-voltage condition can result in high NiMH battery temperatures that, in some cases, can reach levels sufficient to cause melting of the plastic battery door and other adjacent plastic and foam device components.
- RECALL
The firm became aware that the KleenSpec 788 Corded Illuminator has the potential to be incorrectly connected to a commonly available AC power cord instead of the illuminator low voltage transformer power cord which is supplied with the illuminator. This may result in a shattered lamp bulb and a potential electric shock hazard.
- RECALL
GMP deficiencies
- RECALL
Incorrect location of inflatable portion of cuff that may result in cuff falling off patient's arm, error code when used with patient monitor, or an inaccurate reading.
