11. Functional Testing
Functional testing should be carried out at the following intervals 14 days and 30
days. At 14 days carry out a Stage 1 functional test procedure. At 30 days carry
out both Stage 1 and Stage 2 functional testing procedures.
Note: If the ventilator is in use on a patient, the user can postpone the
functional testing to a time when the ventilator is not in use.
Warning: If any of these tests do not function as described and the problem
can not be rectified by reference to the trouble shooting chapter on
page 200, then the unit should not be used until it has been repaired. Please
contact an SLE approved engineer, or SLE.
Warning: The settings used in the functional testing of the ventilator do not
bear any relation to settings for ventilation of a patient. Do not use
functional test ventilation parameters to ventilate a patient.
Warning: The ventilator must not be connected to the patient during these
procedures.
Carry out the “Ventilator Set-up” on page 78 before commencing with the
following tests.
At the end of this chapter the user will find two example check lists that can be
used to record the functional testing routines.
