By Angela Ritchey
The rising volume of surgical procedures and the increasing complexity of medical instruments pose significant challenges for Sterile Processing (SP) departments. These teams must ensure thorough reprocessing of intricate devices while maintaining operational efficiency. Among the essential yet often underutilized technologies in the decontamination process is the ultrasonic cleaner. This tool is particularly effective for cleaning complex surgical instruments—especially those with lumens, hinges, or delicate components—that are difficult to reach through manual or standard automated methods.
Learning Objectives
- Explain how an ultrasonic functions
- Identify challenges ultrasonic use may address
- Review ultrasonic testing methods
