QRS Diagnostic SpiroCard
QRS Diagnostic · Model SpiroCard
Standards: The QRS SpiroCard spirometer provides effective diagnostic tests and meets the following Standards: American Thoracic Society (ATS/ERS) 2005 Standard British Thoracic Society (BTS) Standard National Institute for Health & Clinical Excellence (NICE) Guidelines Lung Age Calculation: Lung age is calculated for patients ages 20-84. It is equal to the predicted FEV1 that matches the patients actual FEV1. Lung age may differ based on the predicted equation chosen. Patented, Pre-Calibrated Mouthpiece: With the QRS SpiroCard spirometry system, everything the patient touches is thrown away. No sterilization or calibration is necessary, saving time for nurses, therapist and physicians. No Batteries Required: The QRS SpiroCard spirometer draws its power from the PC it is connected to via USB port.
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.
Will not power on or unexpected shutdown
HighSymptoms: The respiratory therapy is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

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: Sensor / electrode fault or drift / QC failure
- Run the relevant calibration and check the sensor / electrode status screen.
- De-bubble / rinse the measuring path and check for protein deposits.
- Replace an electrode / membrane / sensor cassette at end of life or that fails calibration.
- Confirm the solution pack / reagent cartridge and calibration gas are in date and not empty.
- Re-run QC at the relevant levels before releasing results.
Symptom: Sample not aspirated / clot / inlet alarm
- Run the inlet / preheater clot-removal or rinse routine.
- Inspect the inlet probe and gasket.
- Replace the inlet gasket or probe.
- Confirm free sample aspiration with a QC sample.
- Replace worn peristaltic pump tubing if transport is still poor.
Symptom: Result flagged / questionable vs the clinical picture
- Repeat with a fresh sample / strip / cassette from correctly stored, in-date stock.
- Run the QC controls at each level.
- Confirm the meter / analyzer is coded / calibrated to the current lot.
- Clean the measurement chamber / strip port and the optics per the manual.
- Quarantine the lot if QC fails; refer the analyzer if QC passes but a result still looks wrong.
Symptom: Will not power on / short battery life / strip-port fault (handhelds)
- Fit fresh batteries or confirm the charger / dock.
- Clean the strip-port contacts / optics.
- Try several strips from a fresh vial.
- Replace the battery.
- Replace the meter if it will not read known-good strips.

- RECALL
QRS Diagnostic has initiated a recall involving Universal ECG 12 Lead IEC ECG Devices. This recall has been initiated because the chest lead wires on these devices may have been improperly labeled. Incorrect labeling of the lead wires could result in improper lead wire placement on the patient which may result in inaccurate waveforms being displayed to the user and an inaccurate interpretatio
