- To perform the system test, the patient must be disconnected from the anesthesia device.
During this time, sufficient ventilation of the patient (e.g. via the resuscitator) has to be ensured.
Because the system test takes up to 8 minutes (depending on the device type), the assistance
of an experienced user is required for this step.
- Before starting the system test for any device of the Apollo- and Fabius families, it is important
to inspect the piston membrane for condensation and remove any condensation.
- If, for clinical reasons, it is not feasible to perform a system test every 24 hours, we recommend
performing the test at least every 72 hours to reduce the likelihood of device malfunctions.
- The system test always consists of a manual part (checklist) and a (semi-) automatic part,
for which both have to be performed .
3.2 System restart & refreshing internal memory
- To prepare the software (clean internal memory components) of a Dräger anesthesia system
for long-term ventilation, we recommend that you restart (switch the device off and on again at
the user interface) the device before preparing it for a new patient.
o
Perseus A500: A restart is required after 28 days, but only after switching to standby.
Starting operation again will only be possible in that situation, after a restart and system
test of the device.
o
Apollo: A restart is necessary to access the system test.
o
Fabius family: The restart procedure is part of the Fabius system test and occurs by
pressing “Run System Test”. No separate restart required.
3.3 Check for overall status and accessories
- Since Dräger anesthesia devices are not designed for long-term ventilation, the overall status
of the device and its accessories has to be checked regularly (at least every 12 hours,
ideally more frequently). In particular, the following situations have to be prevented: exhausted
