Spacelabs 91369 Ultraview SL
Spacelabs · Model 91369 Ultraview SL
Portable monitor designed for use as a compact bedside monitor or as a battery-operated transport monitor. Spacelabs 91369 Ultraview SL Compact Monitor has a large 10.4 inch touchscreen display. Like the 90369, this unit uses dual-battery slots which make this Ultraview very portable. All prior and current Spacelabs modules are compatible with the 91369. The 91369 monitor is a lightweight, portable monitor designed for use as a compact bedside monitor or as a battery-operated transport monitor. The monitor features a five-wire, resistive touchscreen and can be operated on either AC mains or battery power. The single-high module slot on the right side of the monitor accepts all single-high modules, including the 90496 Ultraview® Command module and 91496 Ultraview SL™ Command module, to permit the monitoring of parameters such as electrocardiography (ECG), pulse oximetry (SpO2), temperature, and invasive pressure.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
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.
A parameter drops out or reads wrong
HighSymptoms: ECG, IBP, SpO2, temperature, CO2 or CO intermittently drops or is implausible.
Root cause: Worn patient cable / sensor, or a parameter-module / input-board fault.
NIBP will not measure or is inaccurate
MediumSymptoms: NIBP times out, cuff will not inflate / hold, readings implausible.
Root cause: Internal NIBP pump or valve, a cuff / hose leak, or a pressure-transducer fault.
Module / parameter not recognised
MediumSymptoms: The host does not display a plugged-in module or a built-in parameter.
Root cause: Docking / connector fault or an internal board fault.
Display / touchscreen fault
MediumSymptoms: Blank, dim or distorted display; unresponsive touchscreen.
Root cause: Display, backlight, or controller fault.
Battery / power fault
MediumSymptoms: Short battery run time, will not hold charge, will not power on.
Root cause: Aged battery pack or a power-supply fault.
Network / central-station connectivity fault
LowSymptoms: Monitor not shown at the central station, admit fails, intermittent drop.
Root cause: Wired / Wi-Fi network configuration or a communication board.

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: A parameter drops out or reads wrong (ECG / IBP / SpO2 / temp / CO2 / CO)
- Reseat the patient cable at the module and at the monitor.
- Swap in a known-good cable / sensor for that parameter and re-test.
- Move the module to another host or slot to tell module from host.
- Inspect the module docking connector for bent or recessed pins.
- Verify against a patient simulator; replace the cable, or refer the parameter module / input board if the fault stays with it.
Symptom: NIBP will not measure or is inaccurate
- Leak-test the cuff and hose (occlude and watch for pressure decay).
- Run the monitor's NIBP calibration-verification against a calibrated manometer.
- Confirm correct cuff size and placement and check for a kinked hose.
- Verify against a NIBP simulator at several pressures.
- Refer the monitor for internal pump / valve service if it still fails.
Symptom: Blank / dim / frozen display or unresponsive touchscreen
- Power-cycle the monitor fully (mains removed, battery out where possible).
- Check the display backlight and the display / touchscreen cable.
- Note any boot or self-test error code.
- Re-calibrate the touchscreen if the touch offset is the issue.
- Replace the display / touchscreen assembly or refer the main board.
Symptom: Not shown at the central station / network dropout
- Confirm the wired drop or Wi-Fi settings and that other monitors on that segment are online.
- Check the monitor's network address / unit-bed assignment and re-admit.
- Reseat the network card / cable.
- Restart the monitor's network interface.
- Escalate a whole-unit outage to the central-station server / IT.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The clinician did not realize the monitor was in END CASE mode and was expecting audible alarms. Visual alarms continue to work normally. The firm performed a retrospective analysis of all recalls since 2011 and discovered 222 additional serial numbers were missed and were not included in the previous recall under RES 59456 (recall number Z-3032-2011).
- RECALL
The clinician did not realize the monitor was in END CASE mode and was expecting audible alarms. Visual alarms continue to work normally.
- RECALL
Spacelabs received a report of the Model 91518 Multigas Analyzer trending low levels of an anesthetic agent that is not present during a particular case. The error is limited to only the trend table data.
- RECALL
Monitor may reset repeatedly which can result in a loss of patient monitoring for several minutes. Cause is a software problem.
- RECALL
Telemetry Modules are failing to alarm for low heart rate and asystole.
- RECALL
During battery insertion there is potential for patient waveforms to move to an open receiver module or to an occupied receiver causing the intermittent inappropriate monitoring of both patients for several minutes.
- RECALL
Inaccurate partial pressure readings; readings are not compensated for ambient pressure in mmHg or kPa.
