A Bowie-Dick test is a daily check of air removal and steam penetration in a vacuum-type or prevacuum steam sterilizer. This guide explains what the test can show, how to respond to a failed or indeterminate result, and why the sterilizer should remain on hold until the issue is assessed and the test passes.
Read moreBiological indicators are designed to challenge a sterilization process, but their results can be undermined by poor storage, mishandling, contamination, or weak traceability. This practical framework helps CSSD and quality teams control the period before incubation and interpretation.
Read moreMechanical, chemical, and biological monitors provide different evidence about a sterilization process. Understanding their distinct roles and limitations helps CSSD teams interpret records, investigate disagreements, and make release decisions without claiming more than the evidence supports.
Read moreA structured monitoring program helps outpatient and dental teams review sterilizer performance, assess indicators, document results, investigate exceptions, and make traceable release decisions.
Read moreProcess challenge devices are useful only when their design and intended use match the sterilizer, cycle, load, and monitoring question. This practical guide distinguishes air-removal tests from other PCD applications and explains how to standardize placement, document results, and investigate failures.
Read moreElectronic sterilization records can become temporarily unavailable because of network, software, printer, or interface failures. A predefined downtime process helps CSSD teams preserve load identity, monitoring evidence, disposition decisions, and post-event reconciliation without weakening release controls.
Read moreMechanical records, chemical indicators, biological indicators, and air-removal tests provide different types of evidence. When their results disagree, classify the discrepancy, place affected loads on hold when required, and apply the facility’s modality-specific procedure rather than allowing one result to automatically override another.
Read moreA preventive-maintenance program helps organizations keep sterilization equipment under defined control. This article focuses on equipment-specific planning, role assignments, maintenance records, calibration status, and documentation practices. Detailed decisions about returning a sterilizer to service after maintenance or repair should be addressed in a separate procedure.
Read moreSterilization packaging must support access to the selected process and preserve the sterile barrier afterward. This focused framework helps CSSD teams distinguish packaging-system, process-monitoring, and package-integrity questions without replacing device, packaging, sterilizer, or facility instructions.
Read moreSterilizer requalification should follow a documented change-control assessment rather than an automatic calendar schedule or identical test package. This framework focuses on how CSSD and quality teams determine whether a change requires verification, requalification, investigation, or another defined response before routine use resumes.
Read moreNon-condensable gases can interfere with steam contact and heat transfer, while a passing cycle record or chemical indicator may not reveal every air-removal problem. This article presents a source-based framework for recognizing, investigating, and documenting suspected non-condensable gas events.
Read moreRigid sterilization containers are part of the sterile barrier system, not merely transport trays. A structured, IFU-based inspection of filters, gaskets, latches, seals, and container surfaces can help sterile processing teams identify defects before they affect processing or sterile storage.
