Vyaire MasterScreen Pneumo
Vyaire · Model MasterScreen Pneumo
The heated pneumotach meets the ATS standard 24-26 waveform analysis protocol for accuracy The pneumatach has been designed to work with the validated MicroGard® II bacterial/viral filter and is easy to disassemble and clean The Occlusion option using the interrupter method requires minimal cooperation and coordination for quick airway resistance estimates, making it ideal for preschool children through adults From a single screen, patient data can be entered, flow sensor calibrated, tests performed, QA checked, and patient data trended. We call this SentrySuite 360 Guidance provides real-time instructions on performing the test (quiet breathing, complete inspiration, blast out, complete inspiration.) and includes both text and visual graphics Quality Feedback shown directly on the screen for each maneuver based on quality check types according to ATS/ERS, NIOSH, and Office Spirometry standards Trending of current data to past visits is as easy as pressing a button.
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.
