Self tests (SST and EST)
NOTE:
Covidien recommends that you always run the full EST before
placing the ventilator into operation following service and as
part of the ventilator’s routine performance verification. For
more information on performance verification, see the
700 Series Ventilator System Service Manual.
Follow these steps to run EST:
1. Set up the ventilator as for normal operation, complete with
humidifier, if applicable, and leak-tight ventilator breathing
circuit.
2. Turn on the ventilator. If ventilation has already begun, you
must turn off the ventilator, then turn it back on without
starting ventilation. This allows you access to the Self test menu
function.
3. Press MENU, turn the knob to select Self test, then press ACCEPT.
4. Turn the knob to select Extended self test. The window displays
the messages shown in Table 4-5.

This message is displayed (followed by a countdown) if
you just turned on the ventilator. The ventilator must
be on for 10 minutes before running EST so that
component temperatures can stabilize.
If the ventilator was recently running and is already
warmed up, you can press CLEAR to override the Vent
warming message and begin SST. Covidien cannot
guarantee the accuracy of test results in this case,
however.
Confirm that patient is disconnected by pressing
ACCEPT; or press CLEAR to return to service menu.
