Ventilator & Calibration Troubleshooting

Device Hardware Problems – O2 Flow
A successful calibration harmonizes a signal chain comprising
electrical components (e.g. PGA) mechanical components (e.g. flow
screen).
Note: Changing the O2 Valve may resolve the failure, but not
address the root cause.
• More than one component may change and then
allow for a successful calibration.
• Intake Gas Port (and sintered bronze filter).
• Flow Screen is dirty. Needs to be cleaned/replaced.
• O2 Valve
- Leaky valve / debris
- Broken apparatus
• When the identified problem has been fixed, use the
discrete test to confirm that the device hardware can
now calibrate
TSI Measurements (Flow and Low Pressure)
• The most common faults are related to equipment/
setup mistakes.
• Check Set Up
• Check TSI Connection
Faulty O2 Regulator
Problems are common with the gas supply during calibration.
In the event a calibration fails, the corresponding pneumatic
system may require maintenance prior to being able to be
calibrated.
• It is important to regularly inspect log and study files
to ensure proper function. (See Test Station and
Diagnostic)
• Check Faulty O2 Regulator
• Check O2 Supply
• Check TSI Data Cables
Multiple RCS applications:
Another RCS application running in the background may already
have an active/open connection to the device.
• Close all applications.
• Restart PC.
