Chemical indicators for steam sterilization are essential tools used in healthcare settings to verify the effectiveness of autoclave sterilization processes. These indicators typically contain heat-sensitive chemicals that undergo a visible change, such as a color shift, when exposed to specific temperatures achieved during the steam sterilization cycle. This change indicates whether critical parameters like time, temperature, and steam penetration were met, ensuring that medical instruments and equipment are properly sterilized and safe for patient use. They are crucial for compliance with regulatory standards and ensuring infection control in healthcare facilities.
