Occupational Safety Training for Operating Electrocardiogram (ECG) Machines

1. Overview of the Electrocardiogram (ECG) Machine

a. What is an Electrocardiogram (ECG) Machine?

The Electrocardiogram (ECG) machine is a widely used medical device that records the electrical activity of the heart. It captures electrical changes in the heart through sensors attached to the patient’s skin, typically on the chest, arms, and legs. These changes reflect the activity of heart muscle cells during contraction and relaxation.

Recording an ECG allows doctors to assess the integrity of the heart’s electrical system, detect heart rhythm problems, and evaluate abnormalities in cardiac electrical activity. The ECG machine produces a chart called an “electrocardiogram,” displaying different electrical waves over time, providing detailed information on the shape and interval of the heart’s electrical signals.

By analyzing an electrocardiogram, doctors can diagnose and monitor many cardiovascular conditions, including but not limited to angina, arrhythmias, heart failure, endocarditis, and complications from other diseases such as diabetes.

The ECG machine has become an essential tool not only for diagnosing heart diseases but also for monitoring patients’ cardiovascular health during treatment and recovery.

b. How the Electrocardiogram (ECG) Machine Works

The operating principle of the ECG machine is based on recording and analyzing the heart’s electrical activity. Here’s how it works:

• Electrodes: ECG machines use sensors attached to the patient’s skin to capture electrical signals from the heart. These electrodes are usually placed in multiple locations such as the chest, arms, and legs.
• Signal Recording: As the heart works, heart muscle cells generate small electrical currents. The sensors on the skin record these electrical changes and transmit them to the ECG machine.
• Amplification: The electrical signals from the sensors are very small, so they are amplified to create larger, measurable signals.
• Filtering: Signals are filtered to remove noise and retain only accurate cardiac signals.
• ECG Graph: The electrical signals are plotted on a time-based chart, showing ECG waves, including the P wave, PQ interval, QRS complex, and ST segment.
• Analysis: Doctors or medical staff analyze the ECG chart to assess heart function and identify any abnormalities, such as heart rate, rhythm, and variations in the shape and size of waves.

c. Industries Using Electrocardiogram (ECG) Machines

ECG machines are mainly used in healthcare and medical fields. Some key applications include:

• Clinical Medicine: In clinical settings, ECG machines are widely used to diagnose and monitor cardiovascular conditions. Clinicians use ECGs to assess patients’ heart health, detect arrhythmias, valvular heart disease, angina, and other heart-related issues.
• Hospitals and Clinics: ECG machines are used for diagnosis, monitoring, and treatment of cardiovascular diseases. Doctors, nurses, and technicians collect data on heart electrical activity to support treatment decisions.
• Cardiology Clinics: Specialized cardiology clinics use ECGs to evaluate and monitor patients’ heart health, particularly for diagnosing and managing arrhythmias, heart failure, and valve diseases.
• Emergency Medicine: In emergencies, ECG machines are used to assess and monitor patients’ hearts, enabling rapid identification of critical heart conditions and timely interventions.

2. Overview of Occupational Safety Training for Operating Electrocardiogram (ECG) Machines

a. What is Occupational Safety Training?

• Occupational safety training for operating ECG machines equips workers with knowledge on preventing workplace accidents. Workers who directly operate ECG machines belong to Group 3.
• Safety training helps workers recognize and prevent hazards, reducing risks of workplace accidents during operation.

b. Training Duration

Initial Safety Training Duration:

• Total training time is at least 24 hours, including assessment time.
• 8 hours of theoretical study on policies and labor safety laws.
• 8 hours of theoretical study on basic occupational safety and hygiene knowledge.
• 4 hours of theoretical study on specialized training content.
• 2 hours of practical exercises on specialized training content.
• 2 hours for final theoretical assessment.

The training center may split the program into multiple sessions based on worker schedules, typically conducted over 6 sessions in 3 days, assuming the company can arrange continuous learning time.

Periodic Safety Training Duration:

• Before the occupational safety card expires, workers must undergo periodic safety training, with a duration of at least 50% of the initial training duration.

Explanation: Total duration for periodic safety training is at least 12 hours, including assessment. Upon completing the periodic training and passing the test, workers receive a renewed occupational safety card.

c. Training Content

d. Occupational Safety Card

After completing safety training and passing the assessment, workers will be issued a Group 3 occupational safety card (commonly called Group 3 occupational safety certificate).

The card shows details such as name, date of birth, specific job and work environment, training duration, red seal, and signature confirming completion of the course.

According to the regulations in Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the worker has a labor contract, the employer must sign, stamp, and seal the card after the worker completes the Group 3 training and passes the test.
• If the worker is freelance or temporary, the training organization must sign, stamp, and seal the card after the worker completes the training and passes the test.

3. Hazards for Workers Operating Electrocardiogram (ECG) Machines

Operating an electrocardiogram (ECG) machine generally does not pose major hazards to workers, but safety measures must still be followed to ensure safe and effective operation. Below are some hazards that may occur when operating an ECG machine and measures to mitigate them:

• Risk of electrical contact: Although ECGs use small electrical signals that are painless, workers need to be careful to avoid contact with wires or conductive parts of the machine while it is operating.
• Risk of overwork: Medical staff or technicians often work long hours and frequently with ECG machines. Continuous work can cause fatigue and stress, affecting work performance and health.
• Chemical risk: Some gel solutions may be used to help ECG sensors better contact the skin. However, improper use or prolonged contact with the gel may cause skin irritation or allergies.
• Ergonomic and posture risk: Workers should pay attention to their posture and frequently change positions to avoid muscle and joint strain.
• Information misinterpretation risk: Reading and interpreting ECG charts requires professional knowledge and skills. Misunderstandings or inaccuracies can lead to incorrect diagnoses and ineffective patient treatment.

To minimize these hazards, occupational safety measures should be implemented, including training workers on safe and effective use of ECG machines, providing appropriate personal protective equipment, ensuring comfortable and safe working conditions, and following hygiene and occupational safety practices.

4. Occupational Accident Control Measures When Operating ECG Machines

To control and reduce the risk of occupational accidents when operating ECG machines, there are several safety measures workers need to follow. Below are some occupational accident control measures for operating ECG machines:

• Training and guidance: Provide comprehensive training and guidance on safe and effective use of ECG machines to all medical staff or technicians working with these machines. Ensure they understand the hazards and necessary safety measures.
• Use of personal protective equipment: Provide PPE such as gloves, safety goggles, and lab coats to protect skin from direct contact with conductive gel and avoid electrical hazards.
• Periodic equipment checks: Perform regular inspections and maintenance of ECG machines to ensure proper operation and prevent malfunctions caused by technical errors.
