14 Process Monitoring and Load Release
CAUTION: To reduce patient risks associated with exposure to potentially non‑sterile devices or inadequate sterilization procedures,
always use chemical indicators and biological indicators for monitoring the performance of sterilization cycles as described in this manual Always use chemical indicators and biological
indicators per the device manufacturer’s instructions for use (IFU)
All sterilization processes require a comprehensive quality control program that includes sterility assurance monitoring Comprehensive monitoring of the 3M™ Steri‑Vac™ Sterilizer/Aerator GSX
Series consists of three essential elements:
1�
Monitoring of physical parameters (sterilizer cycle reports)
2�
Use of biological indicators (BIs) within the appropriate process challenge device (PCD) or Test Pack
3�
Use of chemical indicators (CIs)
14.1. Physical Parameters and Requirements
DANGER: To reduce the risks associated with exposure to ethylene oxide,
always inspect cycle reports (printout or electronic file) to ensure the total aeration time matches the device manufacturer’s instructions for use (IFU)
CAUTION: To reduce patient risks associated with exposure to potentially non‑sterile devices or inadequate sterilization procedures:
Always inspect cycle reports (printout or electronic file) to ensure the Operator’s programmed parameters or the device manufacturer’s instructions for use (IFU) matches:
•
%RH at the End of Conditioning,
•
Temperature at the End of Conditioning,
•
Actual Gas Exposure Time
Documentation for physical parameters is provided on the 3M™ Steri‑Vac™ Sterilizer/Aerator GSX Series cycle reports (printout and electronic file) Under normal operating conditions, the paper
cycle report produced at the end of the cycle will be similar to the one shown in Figures 80 ‑ 84
Each cycle report should be reviewed prior to load release per facility policies Critical parameters for the preprogrammed cycles are contained in Table 7 Verification of these parameters on
the printed cycle report is illustrated in Figures 92 and 93 Verification of custom cycle performance should be conducted per facility policies For all cycles confirm final status contains
Cycle

on the printout footer (Figure 93) There is space on the cycle report for a signature and date
End time
on the cycle report footer is the date and time (month/day/4‑digit year + hh:mm:ss) when the Stop button was pressed after cycle is complete
Total cycle time
on the cycle report footer is the actual total elapsed time in hours and minutes (hh:mm) of the selected programmed cycle The Total cycle time is the duration between
touching the cycle Start button and when the Cycle Complete text appears on the display screen If continuous aeration was selected, the Total cycle time is the duration between touching the
cycle Start button and touching the Stop button
