Final answer:
The autoclave chamber door is slightly opened at the end of the autoclave cycle to prevent contamination, allow the items to dry, and release the steam and pressure build-up.
Step-by-step explanation:
In an autoclave, the chamber door is slightly opened at the end of the autoclave cycle to prevent contamination, allow the items to dry, and release the steam and pressure build-up.
Opening the chamber door slightly prevents external contaminants from entering the autoclave chamber, helping to maintain the sterility of the items inside. Allowing the items to dry helps to prevent recontamination and ensures that the items are ready for use. Releasing the steam and pressure build-up is necessary to safely open the chamber door without the risk of a sudden release of pressurized steam.
