A. Introduction
Continuous maintenance is a set of tests and inspections to be
done periodically to ensure that the equipment is functioning
properly. It can be done while the equipment is in service by
drivers or other personnel.
1. If a unit fails a given test, it should be taken out of service
and sent to the repair center/department for further inspec-
tion.

every time the driver visits a patient or when their reser-
voir is filled or replaced. It should also be performed when
equipment is transferred between patients.
