Chapter 1
Maintenance Tests
Propaq M Overview
This chapter includes step-by-step procedures for the following types of maintenance tests:
•Calibration and Calibration Checks
•NIBP Valve, Pump, and Tubing Integrity Tests
•Operational Tests
•Functional Verification 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 CO2calibration.
The Troubleshooting chapter in this manual may recommend performing one of more of the
NIBP valve, pump, and tubing integrity tests to help identify and correct potential issues with
the NIBP valve, pump, and/or tubing.
It is necessary to perform Functional Verification Tests after a module is repaired to ensure that
the functions of the Propaq M unit work properly.
Because the Propaq M 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 M Operator’s Guide for the Operator’s Shift Checklist.) It is highly
recommended that the Operational Tests be performed at regular intervals to augment the
automatic testing the Propaq M does to ensure readiness.
