9. I/E filter test Checks pressure drop across
inspiratory and expiratory
limbs of entire patient
system. Checks pressure
drop across filters.

inspiratory filter outlet, and
exhalation (E) tube from/to
expiratory filter inlet, as

10. PEEP
system test
11. Check
valve test
Table 4-6: EST test sequence (continued)
Verifies that PEEP system can
generate and maintain
preset PEEP levels within
either of two sets of limits. If
results are within the inner
set of limits, test passes the
first time. If the results are
outside of the outer set of
limits, test fails the first
time. If the results are
outside the inner limits but
within the outer limits, the
ventilator adjusts its
calibration table in
nonvolatile RAM (NVRAM)
and repeats the test to verify
the calibration. The test fails
if the calibration cannot be
verified after five attempts.
Self tests (SST and EST)
Function Comments
Checks check valves on inlet
and outlet ports of cylinder
and on exhalation limb of
ventilator breathing circuit.
Fault if not passed. Also in
SST. Mandatory in EST, but
optional in SST.
NOTE:
Overriding this fault
could result in
inadequate bacteria
protection or excessive
resistance to inspiration
or exhalation.
