aeration
Post-sterilization process to remove toxic chemical residues from sterilized medical devices.
Full Definition
Aeration is the controlled process of removing toxic chemical residues, particularly ethylene oxide, from medical devices following chemical sterilization. The process involves exposing sterilized items to circulating air at controlled temperatures and humidity levels for specific time periods determined by validation studies. Proper aeration is critical for patient safety, as residual chemicals can cause tissue irritation, allergic reactions, or more serious adverse effects. Aeration parameters, including temperature, airflow, and duration, must be validated for each device type and sterilization load configuration. The process continues until chemical residue levels fall below established safety limits.
Usage
Usage note: Always specify time and temperature parameters when documenting aeration processes.
