San Antonio MMC 121875 Center 2-24-26 ALD-829.xlsx

This file is a technical data log from a Steris ANSC Lab 250 multichannel sterilization monitoring device located at the San Antonio Medical Center (MMC ID: 121875) in San Antonio, Texas, dated February 24, 2026. The spreadsheet contains approximately 1,600 recorded data points captured between 9:17 AM and 10:24 AM, tracking two critical parameters: temperature in degrees Celsius (Channel 1) and pressure in bar (Channel 2). The device recorded readings at two-second intervals throughout the monitoring period.

The data reveals a complete sterilization cycle profile, beginning with a stabilization phase where temperature and pressure remained relatively constant around 13.34°C and 0.9942 bar for approximately 80 minutes. This was followed by a rapid heating phase where temperature increased from approximately 13.5°C to over 122°C while pressure elevated from approximately 0.99 bar to 2.23 bar, representing the active sterilization process. The cycle then entered a controlled cooling and depressurization phase beginning around 9:57 AM, with temperature declining to 87.7°C and pressure dropping to approximately 0.60 bar by 10:14 AM. The final phase from 10:14 AM to 10:24 AM shows re-pressurization and stabilization with temperature declining to approximately 51.64°C and pressure stabilizing around 1.00 bar, consistent with post-sterilization venting and chamber cooling protocols. This data log appears to serve as validation documentation for sterilization equipment performance and cycle integrity at a Department of Army Medical Command facility.
