CBET study plan

Categorize at least 12 medical device families (physiologic monitors, infusion pumps, ventilators, anesthesia machines, electrosurgical units, defibrillators, dialysis machines, lab analyzers, imaging systems) by the physiologic parameter measured or therapy delivered.

Reconstruct from memory the block-diagram signal path (transducer, amplifier, filter, ADC, processor, display) for three monitoring device types.

Compare the operating principles of ventilators, anesthesia machines, and infusion pumps in a written comparison table.

Identify the dominant patient-safety hazard and the typical failure mode for each device family you list.

Trace the full equipment lifecycle (specification, incoming inspection, preventive maintenance, calibration, repair, decommission) for two device types from memory.

Execute and document a simulated PM/calibration procedure on two device categories, naming the required test equipment and the tolerance criteria used.

Explain signal acquisition for ECG, SpO2, NIBP, and capnography, and list the common artifact sources for each.

Construct a troubleshooting decision tree for one device family using a structured symptom-to-subsystem method.

Apply a structured six-step troubleshooting model (verify, gather information, hypothesize, test, resolve, document) to eight written fault scenarios.

Distinguish operator error, environmental cause, and hardware failure in each scenario before proposing a repair.

Select the appropriate test instrument (DMM, oscilloscope, patient simulator/analyzer, electrical safety analyzer) for a described fault and justify the choice.

Diagnose faults confined to power-supply, sensor, and interconnect subsystems using measured values rather than substitution.

Solve at least 15 timed mixed practice scenarios in problem solving and score 80% or better.

Sequence a complete electrical safety test (ground continuity, chassis and patient leakage current, insulation) and interpret results against pass/fail limits.

Describe how a work order flows through the CMMS from open to close, including how findings are documented for traceability.

Justify, for a described fault, whether a device is removed from service, repaired in place, or returned to service.

Diagram the end-to-end data path from a bedside device through an interface/connectivity engine into the EHR, including wired and wireless segments.

Differentiate HL7 v2 message types (ADT, ORU, ORM) and state what clinical content each carries.

Explain the purpose of DICOM and describe how a modality worklist is populated and used.

Describe medical-device cybersecurity controls (asset inventory, network segmentation, patching, access control) and where each applies.

Assign ownership (IT, BMET, vendor) for eight common device-integration problems and defend each assignment.

Explain the service-work implications of HIPAA privacy and security rules, including PHI on device storage, disk/media disposal, and remote vendor access.

Apply the hierarchy of controls to five healthcare facility hazards and rank the resulting mitigations.

Describe fire response and evacuation procedures, electrical safety requirements, and medical-gas/oxygen-enriched-atmosphere precautions.

Explain how recalls and hazard alerts are received, triaged, and closed out in a hospital equipment program.

Label the major body systems and state, for each, at least one device you service that interfaces with it.

Compute Ohm's law, power, series and parallel resistance, and decibel conversions across 10 practice problems without reference.

Identify resistors, capacitors, inductors, diodes, transistors, and op-amps from schematic symbols and state each component's function in a device circuit.

Select the correct precaution (ESD control, lockout/tagout, PPE, oxygen-safe tools) for a described task.

Complete two full-length timed practice exams and score 80% or better on each.

Re-study the 10 weakest objectives identified in your cumulative error log.

Reproduce the device-function matrix, key formulas, and safety limits from memory.

Condense all notes into a single formula and concept sheet for final review.
