Understanding Electrocardiograph Maintenance

What are the main components of an electrocardiograph?

• Electrodes, lead system, ECG machine.

• Thermometer, sphygmomanometer, pulse oximeter.

• Ultrasound machine, MRI scanner, X-ray machine.

• Heart rate monitor, blood pressure cuff, stethoscope.

Why is routine maintenance important for an electrocardiograph?

• Routine maintenance is only necessary for older models.

• Routine maintenance is important for ensuring accuracy, reliability, and longevity of the electrocardiograph.

• Routine maintenance is not needed if the device is used infrequently.

• Routine maintenance can be skipped if the device appears to be functioning well.

What is the purpose of calibrating an electrocardiograph?

• The purpose of calibrating an electrocardiograph is to ensure accurate and reliable measurements of heart electrical activity.

• To determine cholesterol levels in the blood.

• To measure blood pressure accurately.

• To assess lung function during exercise.

Name a common issue that can occur with an electrocardiograph.

• Incorrect lead placement

• Inaccurate heart rate measurement

• Excessive noise interference

• Poor electrode contact

What safety protocols should be followed when using an electrocardiograph?

• Use unsterilized equipment

• Follow hygiene protocols, ensure proper calibration, monitor patient comfort, and check for contraindications.

• Skip calibration checks

• Ignore patient history

How often should routine maintenance be performed on an electrocardiograph?

• Every 2 years

• Only when malfunctioning

• Monthly checks are required

• At least once a year, preferably every 6 months.

What tools are typically used for calibrating an electrocardiograph?

• Calibration signal generator, multimeter, software tools

• Digital scale, pulse oximeter, ECG paper

• Blood pressure cuff, thermometer, stethoscope

• Heart rate monitor, oscilloscope, signal amplifier

Describe a troubleshooting step for a malfunctioning electrocardiograph.

• Verify electrode placement.

• Check the power supply connection.

• Replace the printer paper.

• Update the software version.

What records should be kept for electrocardiograph maintenance?

• Calibration logs, service history, repair records, inspection reports, software updates.

• Heart rate monitoring protocols

• Patient medical history

• Electrode placement guidelines

How can you ensure the accuracy of an electrocardiograph reading?

• Use a single electrode for all leads

• Ensure proper electrode placement, skin preparation, machine calibration, patient comfort, and minimize electrical interference.

• Calibrate the machine only once a year

• Ignore patient movement during the test
