Top 10 Questions for EEG Technician (Electroencephalogram Technician) Interview

1. Describe the steps involved in performing an EEG recording?

The steps involved in performing an EEG recording are as follows:

• Patient preparation: The patient is positioned comfortably in a reclining chair or bed. The scalp is cleaned with an alcohol solution to remove any oils or dirt that could interfere with the recording.
• Electrode placement: Electrodes are small, metal discs that are attached to the scalp using a conductive paste. The electrodes are placed in specific locations according to the international 10-20 system.
• Recording: The EEG recording is typically performed for 20-30 minutes. During this time, the patient is asked to remain still and relaxed. The EEG machine records the electrical activity of the brain and produces a tracing that can be analyzed by a neurologist.
• Interpretation: The neurologist will interpret the EEG recording and look for any abnormalities in the brain’s electrical activity. These abnormalities can indicate a variety of conditions, including epilepsy, seizures, and brain tumors.

2. What types of equipment are used in EEG recording?

Electrodes

• Used to pick up electrical signals from the scalp.
• Made of metal, such as gold, silver, or platinum.
• Attached to the scalp using a conductive paste.

EEG machine

• Records the electrical activity of the brain.
• Produces a tracing that can be analyzed by a neurologist.
• May also include software for data analysis and storage.

Computer

• Used to store and analyze EEG data.
• May also be used to generate reports and images.

3. What are the different types of EEG recordings?

There are several different types of EEG recordings, including:

• Routine EEG: This is the most common type of EEG recording. It is performed to evaluate a patient with suspected epilepsy or other neurological disorders.
• Ambulatory EEG: This type of EEG recording is performed while the patient is ambulatory, or moving around. It is used to evaluate patients with suspected seizures that are not easily captured on a routine EEG.
• Video EEG: This type of EEG recording combines EEG with video monitoring. It is used to evaluate patients with suspected seizures or other neurological disorders that cause abnormal movements.
• Sleep EEG: This type of EEG recording is performed while the patient is sleeping. It is used to evaluate patients with suspected sleep disorders, such as narcolepsy or sleep apnea.

4. What are the indications for performing an EEG recording?

EEG recordings are indicated for a variety of reasons, including:

• Epilepsy: EEG is the gold standard for diagnosing epilepsy and seizures.
• Other neurological disorders: EEG can also be used to diagnose and monitor other neurological disorders, such as brain tumors, strokes, and encephalopathy.
• Sleep disorders: EEG can be used to diagnose and monitor sleep disorders, such as narcolepsy and sleep apnea.
• Head injuries: EEG can be used to evaluate patients with head injuries and to monitor their recovery.

5. What are the contraindications for performing an EEG recording?

There are no absolute contraindications to performing an EEG recording. However, there are some relative contraindications, such as:

• Active skin infections: EEG electrodes should not be placed on areas of the scalp that are infected.
• Recent head surgery: EEG electrodes should not be placed on areas of the scalp that have recently been operated on.
• Patients with pacemakers: EEG recordings can interfere with the function of pacemakers. Therefore, it is important to inform the neurologist if you have a pacemaker before undergoing an EEG recording.

6. What are the potential complications of performing an EEG recording?

EEG recordings are generally safe and well-tolerated. However, there are some potential complications, such as:

• Skin irritation: The conductive paste used to attach the electrodes can cause skin irritation in some patients.
• Bleeding: In rare cases, the electrodes can cause bleeding if they are inserted too deeply into the scalp.
• Infection: If the electrodes are not properly sterilized, they can cause infection.

7. How do you ensure the quality of EEG recordings?

There are a number of factors that can affect the quality of EEG recordings, including:

• Proper electrode placement: The electrodes must be placed in the correct locations according to the international 10-20 system.
• Proper skin preparation: The scalp must be cleaned with an alcohol solution to remove any oils or dirt that could interfere with the recording.
• Patient cooperation: The patient must remain still and relaxed during the recording.
• Proper equipment maintenance: The EEG machine and electrodes must be properly maintained and calibrated.

8. What are the ethical considerations in performing EEG recordings?

There are a number of ethical considerations in performing EEG recordings, including:

• Patient consent: Patients must give informed consent before undergoing an EEG recording.
• Confidentiality: EEG recordings are confidential and should not be shared with anyone without the patient’s consent.
• Respect for patient autonomy: Patients have the right to refuse an EEG recording or to withdraw their consent at any time.

9. What are the emerging trends in EEG technology?

There are a number of emerging trends in EEG technology, including:

• Wireless EEG: Wireless EEG systems allow patients to move around more freely during recordings. This can be beneficial for patients with ambulatory epilepsy or other movement disorders.
• High-density EEG: High-density EEG systems use a larger number of electrodes than traditional EEG systems. This can provide more detailed information about the brain’s electrical activity.
• Quantitative EEG: Quantitative EEG (qEEG) is a technique that uses computer algorithms to analyze EEG recordings. This can help to identify patterns and abnormalities in the brain’s electrical activity.

EEG Technicians (Electroencephalogram Technicians) play a crucial role in the healthcare field by assisting neurologists and other healthcare professionals in diagnosing and monitoring brain disorders. Their key job responsibilities include:

1. Patient Care

Providing a comfortable and safe environment for patients undergoing EEG examinations.
