Safety Considerations
The following section describes general warnings and safety considerations for operators and
patients. Service technicians should review the safety considerations prior to servicing any
equipment and read the manual carefully before attempting to disassemble the unit. Only
qualified personnel should service the Propaq MD unit.

Chapter 1
Maintenance Tests
Propaq MD Overview
This chapter includes step-by-step procedures for various maintenance tests. At a minimum, a
trained biomedical technician must perform a CO2calibration and an NIBP calibration check
once per year. A CO2calibration check may be performed at any time to verify the CO2
calibration. It is necessary to perform maintenance tests after a module is repaired to ensure that
the functions of the Propaq MD unit work properly. Use the checklist at the back of this
document (ZOLL Propaq MD Maintenance Tests Checklist) to record your results of the
maintenance tests.
Because the Propaq MD units must be maintained ready for immediate use, it is important for
users to conduct the Operator’s Shift Checklist procedure at the beginning of every shift. This
procedure can be completed in a few minutes and requires no additional test equipment. (See
the ZOLL Propaq MD Operator’s Guide for the Operator’s Shift Checklist.)
