What not to ask
How to document what staff actually observed
The Simple Version
Ask the user to walk through what they were trying to do, what actually happened, and what the device displayed or sounded. Then identify what still worked, what accessories and network connections were present, whether the problem repeats, and what changed before it began. These questions reconstruct the operating conditions instead of asking staff to diagnose the component.
Use neutral wording. “What did you see next?” preserves observations better than “Did the battery fail?” Capture exact alarm text, settings, patient connection state, time, room, and any workaround. A two-minute conversation at the device can prevent hours of testing under the wrong conditions.
Worked Example: “The Pump Stopped”
Ask whether the display went blank, delivery paused, or an alarm stopped the infusion. Ask for the exact alarm, programmed rate, tubing and channel, power source, door state, and what staff did next. “Downstream occlusion after the patient repositioned” leads to a different bench test than “screen went black when the power cord moved.”
Repeat the complaint back in technical but neutral language and document who observed it and when. Do not dismiss a symptom because it cannot be reproduced immediately; clinical context may identify an intermittent accessory, setup, environmental, or network condition that the empty bench lacks.
Start With What They Actually Saw
Ask:
- What exactly happened?
That is much better than:
- What's wrong with it?
You want observations.
Examples:
- Screen went black
- Pump stopped
- NIBP cuff would not inflate
- SpO2 disappeared
- Central station lost the monitor
- Device restarted
These are useful symptoms.
Avoid Leading Questions
Do not start with:
- Do you think the battery is bad?
Now you have introduced your theory into the conversation.
Ask:
- What happened when you unplugged it?
Let the evidence come first.
Symptom vs Interpretation
Clinical staff may say:
The battery is bad.
What they may actually mean is:
It shuts off when we unplug it.
Those are not the same statement.
Document the observed symptom.
Ask What They Were Trying to Do
Equipment behaves differently depending on mode and workflow.
Ask:
- What were you doing when it happened?
Examples:
- Taking NIBP
- Charging
- Printing ECG
- Transferring patient
- Starting ventilation
- Sending results to central
- Why Workflow Matters
A device may fail only during one function.
Example:
Monitor works normally until NIBP starts.
Then it reboots.
That points you toward a load-dependent power problem much more quickly than:
Monitor randomly restarts.
Ask Whether It Happens Every Time
This separates:
- Constant failure
- Intermittent failure
Ask:
- Can you make it happen again?
or:
Does it happen every time you do that?
If It Is Intermittent
Ask:
- How often?
- Any pattern?
- Only after running awhile?
- Only during transport?
- Only in one room?
- Only with one accessory?
Intermittent does not mean random.
Ask What the Screen Said
Error messages are valuable.
Ask:
- Did any message appear?
Try to get the exact wording.
"Some battery message" is less useful than:
Battery communication lost.
Ask About Alarm Sounds
Ask whether the device:
- Alarmed
- Beeped once
- Produced continuous tone
- Went silent
Different alarm behavior can tell you how far the system got before failing.
Ask What Still Worked
This is one of the best questions.
If a patient monitor loses SpO2 but:
- ECG works
- NIBP works
- Display works
that is very different from the whole monitor shutting down.
Ask Whether They Tried Another Accessory
This can be useful if they already performed a swap.
But verify what they mean by:
We tried another one.
Was it actually compatible and known good?
Ask Where It Happened
Location matters.
Ask:
- Did it happen in this room only?
This is especially useful for:
- Network issues
- Power issues
- Medical gas
- Nurse call
- Central monitoring
- Failure Follows Room
If two known-good devices fail in the same location:
Think infrastructure.
Failure Follows Device
If the same device fails in multiple known-good locations:
Think device or configuration.
Ask If Anything Changed
A very useful question is:
- Did anything change before this started?
Possible changes include:
- New cable
- New software
- Battery replacement
- Room move
- Network change
- Cleaning
- PM
- New disposable
Timing matters.
"It Started After..."
That phrase can be extremely valuable.
It does not prove cause.
But it gives you a strong place to investigate.
Power Problem Questions
For a device that shuts off or will not power on, ask:
- Did it work on AC?
- Did it fail after unplugging?
- Was it charging?
- Did the battery icon look normal?
Did the screen go dark instantly or shut down normally?
Instant Shutdown vs Normal Shutdown
Instant black screen may suggest:
- Power interruption
- Battery disconnect
A controlled shutdown may suggest:
- Software
- Low-battery logic
Different clue.
Charging Problem Questions
Ask:
- Does it run on AC?
- Does it run on battery?
- Does the charge icon appear?
- Does percentage increase?
- Does the problem occur with another battery?
These questions separate:
- Charger
- Battery
- Communication
- NIBP Questions
Instead of:
NIBP doesn't work.
Ask:
- Does the pump run?
- Does the cuff inflate at all?
- Does pressure build and then dump?
- Is there a leak message?
- Does it fail with another cuff/hose?
- Is it every patient?
- Pump Runs but No Inflation
Now think:
- Leak
- Valve
- Hose
- Cuff
rather than no-power condition.
SpO2 Questions
Ask:
- Sensor recognized?
- Pleth waveform present?
- Numeric missing or just unstable?
- One sensor or all sensors?
- Does it work on another monitor?
These separate recognition from signal quality.
ECG Questions
Ask:
- One lead off or all?
- Artifact or no waveform?
- Same cable on another monitor?
- Did it happen during movement?
- Was ESU in use?
- Network Problem Questions
Ask:
- Does the monitor work locally?
- Does it have network link?
- Is it missing only from central?
- One room or multiple rooms?
- Did anything move or change recently?
- Do other monitors in that room work?
- Central Failure With Local Monitoring Normal
That immediately moves you away from patient measurement and toward communication.
Integration Problem Questions
If data is not reaching the EMR, ask:
- Is it visible at bedside?
- Is it visible at central?
- Is patient association correct?
- Is the problem one device or many?
- Did interface or network maintenance occur?
- Follow the Data
The goal is to determine where the data stops.
Alarm Complaint Questions
If staff says:
Alarm isn't working.
Ask:
- Which alarm?
- Did the condition actually cross the threshold?
- Was the alarm paused?
- Did a visual alarm appear?
- Did sound fail but message appear?
- Local only or central too?
- Audible vs Visual Alarm
If visual alarm works but speaker does not:
That is very different from alarm logic not detecting the condition.
Printer Complaint Questions
Ask:
- Does printer make any noise?
- Paper feeds?
- Blank paper?
- Jam message?
- Happens on every print type?
Again, isolate the function.
Touchscreen Complaint Questions
Ask:
- Entire screen unresponsive?
- One area only?
- Works after reboot?
- Physical buttons work?
- Happens after cleaning?
A single dead zone suggests something different from full UI lockup.
Intermittent Complaint Questions
For intermittent problems, ask:
- How long after startup?
- Does movement trigger it?
- Does temperature matter?
- Does it happen on battery only?
- Does it occur with one user workflow?
- Any error before recovery?
- Reproduce the Conditions
If the problem happens after 45 minutes, a five-minute bench test proves very little.
Try to recreate the conditions.
Serious Event Questions
If the device was involved in a serious patient-care event, the approach changes.
Do not casually manipulate or erase evidence.
Gather:
- Exact device
- Time
- Patient-care context
- Reported behavior
Then follow facility incident and preservation procedures.
Do Not Clear Logs First
In a serious event, logs may be important evidence.
Do not reboot, update, or reset unnecessarily before following the required process.
Ask Who Saw It
Sometimes the person dropping off the device did not witness the event.
Ask:
- Who actually saw what happened?
That can prevent secondhand descriptions from becoming distorted.
Firsthand vs Secondhand Information
Document when a complaint is:
- Directly observed
- Relayed by someone else
That matters when the description is unclear.
Ask for Timing
The exact approximate time can help match:
- Device logs
- Central station events
- Network logs
Example:
- It happened sometime overnight
is weak.
Around 02:15 during transport
is much more useful.
Ask What Happened Immediately Before the Failure
Examples:
- Battery swapped
- Cable connected
- Cart moved
- Mode changed
- Patient admitted
- Device unplugged
This can identify the trigger.
Ask What Happened Immediately After
Did the device:
- Recover itself?
- Need reboot?
- Continue working?
- Shut down completely?
Recovery behavior is useful.
Ask Whether Staff Already Tried Anything
Find out what was changed.
Examples:
- Rebooted
- Replaced cable
- Changed outlet
- Moved room
This can provide useful evidence.
But Be Careful With the Result
If they say:
We rebooted it and it worked.
You proved:
It worked after a reboot.
You did not prove:
Software caused the problem.
Ask One Question at a Time
Avoid firing ten questions in one breath.
Staff may be busy.
Start with the highest-value questions.
A Good First Five Questions
For many complaints:
- What were you trying to do?
- What exactly happened?
- Did any error message appear?
- Does it happen every time?
- Was anything specific connected or changed?
That alone may get you most of what you need.
Use Their Language First
If a nurse says:
- The pressure cuff wouldn't pump up,
you do not need to correct them with:
You mean the NIBP pneumatic subsystem failed to generate cuff pressure.
Translate it mentally.
Get the information first.
Do Not Make Staff Feel Tested
The goal is not to quiz clinicians on device theory.
They should not need to know:
- Flow sensors
- Network architecture
- Internal valves
Ask about what they observed.
Bad Question
Did the expiratory valve fail?
They may have no idea.
Better Question
Was pressure staying high between breaths?
Now they can answer from what they saw.
Ask for Photos When Appropriate
If an intermittent error disappears before the device reaches biomed, a photo of:
- Error screen
- Alarm
- Connection setup
can be extremely useful.
Ask Staff Not to Recreate Unsafe Conditions
Do not ask someone to repeat a dangerous event just to prove it happened.
Use logs, controlled bench testing, and safe reproduction.
Clarify "Not Working"
That phrase can mean:
- No power
- No measurement
- Wrong measurement
- Alarm
- Network loss
- Physical damage
Always translate it into an actual symptom.
Clarify "Dead"
"Dead" might mean:
- Screen blank
- Battery dead
- No network
- No ECG
Do not assume.
Clarify "Keeps Disconnecting"
Disconnecting from what?
Patient cable?
Wi-Fi?
Central station?
Power?
The noun matters.
Clarify "It Was Fine Yesterday"
Ask:
- What changed between yesterday and today?
Sometimes the answer is:
- New battery
- New room
- New cable
- New software
Ask Whether Another Device Had the Same Problem
This is especially useful for infrastructure issues.
If several devices fail similarly at once:
Think shared cause.
Ask Whether Another Device Worked There
This gives you a comparison.
Example:
Original monitor cannot connect.
Replacement monitor also cannot connect.
Now think room/network.
Ask If It Was Patient-Specific
Some measurement complaints only occur on certain patients.
If the device works on:
- Simulator
- Other patients
the equipment may be fine.
Patient Conditions Can Affect Measurement
Examples include:
- Low perfusion
- Motion
- Poor electrode contact
Do not automatically diagnose a device failure from one difficult measurement.
Ask If It Was Accessory-Specific
If a problem only occurs with:
- One probe
- One hose
- One cable
the main device may not be the issue.
Ask About Cleaning
If a problem started after cleaning:
Ask whether:
- Fluid entered connector
- Device was still wet
- Strong cleaner used
Cleaning-related damage is common.
Ask About Drops and Impacts
Staff may say:
It just stopped working.
Ask:
- Did it fall or get hit recently?
Physical events matter.
Do Not Accuse
Phrase it neutrally.
You are looking for technical history, not assigning blame.
Ask About Transport
Some failures happen only during movement.
Examples:
- Battery connection
- Wi-Fi roaming
- Cable strain
Ask whether failure occurred:
- At bedside
- During transport
- In elevator
- On battery
- Ask About Environmental Conditions
Was the device:
- Wet?
- Very warm?
- Used outside normal area?
- Near heavy electrical equipment?
Context can matter.
Ask for the Exact Accessory
If there are multiple compatible-looking accessories, note:
- Model
- Part number
- Type
A wrong accessory can create a legitimate complaint.
What Not to Ask
Avoid:
- Are you sure you used it correctly?
That is defensive and usually unhelpful.
Better:
Can you walk me through what was happening when it failed?
Same information, better interaction.
Avoid Immediate Blame
Do not begin with:
IT problem.
or:
User error.
You have not proven either yet.
Avoid Diagnosing Before Reproducing
A complaint can sound obvious and still be misleading.
Gather enough evidence before deciding.
Document the Complaint Accurately
A good work order might say:
Nursing reports monitor intermittently shuts off immediately when AC power is removed despite battery icon showing approximately 80%.
That is much more useful than:
Battery issue.
Separate Reported From Observed
A strong note may distinguish:
Reported: Device shut down twice during transport.
Observed: Unable to reproduce during 45-minute battery test.
That preserves the evidence honestly.
Do Not Rewrite Staff's Complaint Into Your Diagnosis
If staff says:
- NIBP cuff won't inflate,
do not document:
- Pump failed
until you prove it.
Useful Work-Order Language
Use phrases like:
- Staff reports
- User states
- Reproduced
- Observed
- Unable to reproduce
- Verified
These distinguish evidence levels.
Example
Staff reports: Intermittent ECG lead-off during patient movement.
Observed: Reproduced RA lead-off by flexing lead wire near connector.
Now the complaint and your finding connect clearly.
A Useful Troubleshooting Conversation
Start with:
- What were you doing?
Then:
- What happened?
Then:
- What did the device say?
Then:
- What still worked?
Then:
- What was connected?
Then:
- Can it be reproduced?
Then:
- Did anything change recently?
That is a very efficient sequence.
What Did You Actually Prove?
If staff says:
- The battery is bad,
you proved:
Staff believes the complaint involves the battery.
You did not prove:
Battery is defective.
If staff says:
It shut off every time we unplugged AC,
you now have a specific reproducible symptom.
If you reproduce that behavior yourself and a known-good battery corrects it:
Now you have much stronger evidence.
The quality of your troubleshooting depends heavily on the quality of the original symptom.
Final Thoughts for Biomeds
Clinical staff do not need to diagnose the equipment for you.
They need to tell you what happened.
Your job is to turn:
- It doesn't work
into something like:
Device operates normally on AC but shuts down immediately when unplugged, only with Battery A, and no error appears before shutdown.
That is troubleshootable.
Ask about:
- Action
- Symptom
- Error
- Timing
- Accessories
- Location
- What still worked
And do not lead the conversation toward the answer you already suspect.
Good questions save time.
They prevent unnecessary parts replacement.
They help with intermittent problems.
And they give you better evidence before the device ever reaches the bench.
The goal is not to ask more questions.
It is to ask the questions that help you answer:
- What actually happened?
- — Jake
- Important Note
For equipment involved in patient harm, serious safety events, or other reportable incidents, follow facility incident-response and evidence-preservation procedures before performing routine troubleshooting, rebooting, clearing logs, changing configuration, or otherwise altering the device.
