What This Guide Helps With
This guide addresses situations where the integrated scale on the Stryker ProCuity bed:
- Shows weight readings that drift over time
- Displays inconsistent measurements between uses
- Fails to stabilize at a correct weight
The focus is on external, logical troubleshooting first—connections, calibration, and environmental factors—before assuming internal scale failure.
Step-by-Step Troubleshooting
Verify Bed is on a Level Surface
- Ensure the bed is placed on a flat, stable floor.
- Uneven surfaces can cause scale readings to drift.
Check for Obstructions or Load on the Bed
- Remove any items on the mattress except the patient (if safe) or test weight.
- Make sure side rails or accessories are not applying uneven pressure.
Inspect Power Connection and Battery Status
- Confirm the bed is properly plugged in if the scale requires mains power.
- If the bed uses battery backup, ensure batteries are charged.
Confirm Calibration Status
- Review the bed’s scale calibration logs if available.
- Some models allow a manual recalibration; follow manufacturer prompts.
Perform a Zero or Tare Function
- Activate the scale’s zero/tare function with no weight on the bed.
- Observe if the scale stabilizes or continues to drift.
Environmental Considerations
- Ensure temperature and humidity are within recommended ranges.
- Vibrations from nearby equipment can cause drifting readings.
Swap Mattress or Mattress Support Pads
- If the bed uses specialized pads or mattress sensors, remove and reseat them.
- Check for uneven wear or compression affecting weight distribution.
If the Problem Persists
If scale drift continues after external checks:
- Remove the bed from clinical use.
- Label as Out of Service.
- Contact Stryker service or authorized repair personnel for bench evaluation or scale replacement.
- Avoid further use until verified safe, as unreliable weight readings can affect medication dosing, patient monitoring, and safety.
Clinical Use Tip
- Do not rely on the scale for patient weight when readings are inconsistent.
- Move the patient to another bed with a functioning scale before attempting procedures that require accurate weight.
- Document all observations and actions taken before escalation.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Integrated scale shows drifting weight readings and fails to stabilize.”
Cause
What was observed during troubleshooting.
Example:
“Bed on uneven surface; calibration may be out of spec; potential mattress sensor issue.”
Resolution
What action was taken.
Example:
“Verified surface, cleared obstructions, performed zero/tare, reseated mattress sensors; bed removed from service and sent for calibration/repair.”
Helpful Details to Include
- Bed location and floor type
- Battery status and power connection
- Zero/tare attempts and results
- Any unusual noises or resistance from bed mechanisms
- Environmental factors (temperature, vibration)
- Final status before sending for repair
Final Thought
Patient safety requires that weight measurements are accurate and reliable. Logical, stepwise troubleshooting—starting with simple external checks and escalating appropriately—ensures that potential risks are mitigated and proper documentation supports follow-up and maintenance.
That is successful troubleshooting.
