4.2.3.2.1 EST tests: Running individual EST tests (diagnostic EST)
This function lets you run EST tests individually. It operates almost identically to EST, except
that:
• Test results are not written to NVRAM, and
• A test failure does not cause a VENT INOP condition to be declared. Thus, a ventilator that
fails an EST test can continue to operate
for troubleshooting purposes only
.
• Pressing ALARM RESET while running diagnostic EST returns you to the start of the full
(non-diagnostic) EST.
NOTE:
• Covidien recommends you always run the full EST before placing the ventilator into
operation following service. For preliminary troubleshooting purposes, however, you
may want to run EST tests individually. The
EST tests
function does not write error
information into NVRAM nor declare a VENT INOP condition when tests are failed.
• This
EST tests
function does
not
substitute for the full EST. After a ventilator is
serviced, it must be tested using the full EST before being returned to service.
