RoVent Troubleshooting
Check the tubing between the INS and EXP
ports for leaks or loose connections.
The ventilator circuit is open. Do not run the
ventilator prior to connecting the animal.
Verify that the Body Weight or Target tidal
volume setting is correct and that the delivered
tidal volume is an appropriate value for the
animal’s size.
If the error persists, perform a Leak Test in the
Calib & Tests section.
Problem
Possible Cause
Solutions
Tube open to
atmosphere
Tube blocked
Exhaust blocked
Out of regulation
The highest measured
pressure in a breath cycle is
under 25% of the target and
the tidal volume is over target.
The highest measured pressure in
a breath cycle is under 25% of the
target and tidal volume is under
target.
The breath pressure fails to
drop during the expiratory
phase of a breath.
Over five consecutive breaths,
peak pressure was more than
25% or less than 75% of your
target.
Check the tubing for any kinks, blockages or
foreign matter in the inspiratory, expiratory or
exhaust tubing.
Adjust the endotracheal tube to clear any accu-
mulated fluid.
If the error persists, perform a Leak Test and a
system Purge in the Calib & Tests section.
Verify that the cap was removed from the ex-
haust port on the back of the system.
If the error persists, perform a Leak Test and a
system Purge in the Calib & Tests section.
Verify that the settings are correct.
Perform a Deadspace Calibration in the Calib &
Tests section.
If the error persists, perform a Leak Test and
a Zero Sensors calibration in the Calib & Tests
section.
