Symptoms Possible Causes What to Do<br />
Sensitivity does not<br />
appear to be<br />
accurate.<br />
Ventilator is<br />
autocycling.<br />
Circuit leak. Run a leak test and reseat or replace the leaking<br />
parts or connections. See page 11-8 for<br />
instructions.<br />
Sense lines are<br />
reversed.<br />
High or low side sense<br />
line or elbow at patient<br />
wye loose or leaking.<br />
High or low sense lines<br />
are occluded.<br />
High or low sense ports<br />
in the wye are<br />
occluded.<br />
Pressure Control or<br />
Pressure Support set<br />
below PEEP.<br />
The sense lines are not designed to be removed<br />
from either the wye or the luer fittings. If the<br />
sense lines have been removed and replaced<br />
incorrectly, they may not seal correctly when<br />
replaced. Replace the patient wye and sense<br />
lines with a known good assembly.<br />
Check high and low pressure sense lines to be<br />
sure they are correctly attached and securely<br />
seated at both the ventilator and wye ends.<br />
Check the luer fitting connections for leaks.<br />
Check the elbow connectors at the wye to be<br />
sure they have not loosened or been broken<br />
loose.<br />
Verify lines are not occluded or pinched.<br />
Check the exhalation drive line at both the<br />
ventilator and exhalation valve ends. Verify the<br />
line is securely seated and not leaking.<br />
Verify the control values are appropriately set.<br />
Failed autozero. Perform an autozero under XDCR ZERO. See<br />
page 10-28 for more information.<br />
Leak Compensation is<br />
not on.<br />
Failed calibration or<br />
internal problem with<br />
the ventilator.<br />
O2% is high. O2 inlet pressure too<br />
high when Low O2<br />
Source selected.<br />
O2 inlet flow too high<br />
when Low O2 Source<br />
selected.<br />
Verify that the Leak Compensation extended<br />
features option is set to On (default setting is on).<br />
See page 10-12 for instructions.<br />
Immediately contact a certified Pulmonetic<br />
Systems’ service technician.<br />
Verify the low pressure O2 inlet has been<br />
correctly calculated and set using the Input O2<br />
Flow Chart (see page 6-15).<br />
Pulmonetic Systems recommends the use of an<br />
O2 monitor to verify delivered O2%. Adjust the<br />
entrained O2 flow so the monitored value shows<br />
the desired FIO2. (See pages 6-13 and 6-18 for<br />
information on using the Low O2 Source and<br />
O2% features.)<br />
