CBET case studies
CBET · Put your knowledge to work in context.
The Certified Biomedical Equipment Technician (CBET) credential is administered through the AAMI Certification Institute (ACI) and is intended for healthcare technology management professionals who work with the electromechanical devices, computers, networks, and software used in patient care. CBET holders typically work for hospitals, clinics, home healthcare providers, device manufacturers, repair organizations, regulatory agencies, or software and device-integration vendors. Day-to-day duties include preventive maintenance and calibration, clinical and bench troubleshooting, documenting work in a CMMS, supporting regulatory compliance, and resolving medical device network problems. The exam samples six domains: anatomy and physiology (about 7%), fundamentals of electricity and electronics (about 6%), healthcare information technology (about 17%), healthcare technology and function (about 30%), healthcare technology problem solving (about 30%), and public safety in the healthcare facility (about 10%). The CBET case studies are 5 cases and about 4,487 words.
