33 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Common-mode rejection ratio
- The ratio of differential signal gain to common-mode signal gain in an amplifier; high CMRR rejects interference such as 60 Hz power-line noise on ECG leads.
- Patient leakage current limit
- For cardiac-connected patient leads, the allowable leakage current is typically 10 microamperes; patient-contact applications typically allow 100 microamperes.
- Defibrillator energy accuracy
- Delivered energy is verified with a calibrated analyzer and resistive load; tolerance is commonly plus or minus 15 percent of the selected energy setting.
- Infusion pump occlusion alarm
- A pressure-threshold alarm that signals a blocked line; threshold and response time are tested separately from flow-rate accuracy, which is typically plus or minus 5 percent.
- Electrosurgical return electrode monitoring
- A safety system that detects inadequate pad contact or detachment, reducing the risk of burns at the return electrode during electrosurgical procedures.
- SpO2 A(rms) accuracy
- The root-mean-square difference between pulse oximeter readings and reference CO-oximetry values; a common specification is stated as A(rms) with the test range.
- Half-value layer
- The thickness of material that reduces radiation intensity by half; it is a radiographic quality-control measure of beam quality and filtration adequacy.
- Total cost of ownership
- The sum of acquisition, installation, maintenance, training, and disposal costs, minus salvage value, used to compare equipment options over its life.
- Mean time to repair
- Total repair downtime divided by the number of repairs; it measures service responsiveness and supports comparison against service-level targets.
- Uptime percentage
- Available time divided by scheduled time, multiplied by 100; it reflects equipment availability and is a key performance indicator for clinical engineering.
- Work-order priority tiers
- Emergency means immediate patient-safety impact; urgent means clinical impact within hours; routine means scheduled work with no immediate clinical effect.
- In-house versus contract decision
- Compare annual service-contract cost against in-house parts, labor, training, and downtime risk; choose the lower total cost with acceptable risk.
- Risk-based PM interval
- The scheduled maintenance interval is set by clinical criticality, failure consequence, and manufacturer guidance; higher-risk devices get shorter intervals.
- PM completion rate
- The number of preventive maintenance tasks completed on schedule divided by the number due in the period, multiplied by 100.
- Alternate equipment management
- A program that allows scheduled maintenance to follow manufacturer instructions or an approved alternative, justified by risk assessment and documented equivalence.
- Recall and hazard alert process
- Match the alert to inventory records, act on affected devices, document the action, and close the item within a defined timeframe.
- End-of-life trigger
- Conditions such as unavailable parts, unsupported software, rising failure rates, or ceased security patches that indicate a device should be replaced.
- HL7 ORU message
- An observation-result message type that carries clinical results from a device or system to the electronic health record using defined segments and delimiters.
- FHIR Observation resource
- A standardized data resource that carries a coded measurement, its value, unit, and timing, used for interoperable exchange between systems.
- DICOM modality worklist
- A service that sends scheduled imaging orders to the modality, reducing manual entry errors and mismatched patient or study identifiers.
- Network segmentation
- Separating medical devices onto isolated network segments with firewall rules, limiting lateral movement of threats and protecting device availability.
- Network time protocol
- A protocol that synchronizes clocks across devices and systems, enabling accurate correlation of events and log entries during investigations.
- IEC 60601-1 scope
- The general standard for basic safety and essential performance of medical electrical equipment; collateral standards add requirements for electromagnetic compatibility and usability.
- 510(k) substantial equivalence
- A premarket pathway showing a new device is at least as safe and effective as a legally marketed predicate device, without full clinical trials.
- Unique Device Identification
- A standardized identifier on device labeling that enables traceability, inventory matching, and efficient recall management across the health system.
- Medical device reporting
- The requirement to report serious injury or death potentially attributable to a device to the manufacturer and the FDA within defined timeframes.
- Risk priority number
- In failure mode and effects analysis, the product of severity, occurrence, and detection scores; higher values rank failure modes for corrective action.
- Root cause analysis
- A structured review after a sentinel event that identifies system-level contributing factors in process, environment, and staffing rather than individual blame.
- Alarm fatigue mitigation
- Strategies such as patient-specific limits, adjusted default volumes, and alarm-management protocols that reduce nuisance alarms and clinician desensitization.
- RACE fire response
- A sequence for fire emergencies: rescue anyone in danger, alarm, contain the fire by closing doors, and extinguish or evacuate as directed.
- ALARA principle
- A radiation-safety principle meaning doses are kept as low as reasonably achievable, using time, distance, and shielding to limit occupational exposure.
- PASS extinguisher use
- Pull the pin, aim at the base of the fire, squeeze the handle, and sweep side to side; a standard technique for portable fire extinguisher operation.
- Teach-back method
- A communication technique where the learner explains the procedure in their own words, confirming understanding rather than assuming it from a yes answer.
