Self tests (SST and EST)
If the ventilator has already been running for more than
10 minutes before you select Short self test, this message is
bypassed (see step 5). 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.
