EEG wave patterns are the core of clinical diagnostics and long-term monitoring in EEG.

Understanding EEG frequencies is essential for clinical diagnosis in EEG.

Understanding seizure classification is crucial for accurate diagnosis and monitoring in EEG.

Artifact identification and mitigation are key for accurate recordings in EEG.

Post-study analysis creates technical reports summarizing EEG findings for physician interpretation.

HIPAA regulates patient confidentiality and the security of all medical records, including EEG data.

Hippocampal sclerosis is a common cause of temporal lobe seizures, particularly among adults.

Follow facility infection prevention protocols for proper electrode cleaning to ensure patient safety and minimize risks.

The 10-20 System is the standard placement method for electrodes in EEG monitoring, ensuring consistent positioning between tests.

When a patient experiences a seizure, it should be documented immediately with its onset, duration, characteristics, and any interventions. This helps capture crucial information.

A patient with a recent stroke has higher risks from hyperventilation, as it can affect their already compromised nervous system.

The ACNS Guidelines, established by the American Clinical Neurophysiology Society, are essential for maintaining safety standards in EEG monitoring.

Cleaning the scalp thoroughly ensures proper electrode contact and reduces artifacts, crucial for obtaining accurate recordings.

Hyperventilation activation helps evoke brain activity, but if a patient has cardiovascular issues, it could be dangerous due to potential strain on the heart.

Impedance checks measure the electrical resistance between an electrode and the skin, ensuring good contact for accurate recording.

EMG artifacts are caused by muscle activity and result in high-frequency noise in EEG recordings, making it hard to interpret brain signals.

Trending analysis helps understand patterns over time, such as seizure occurrence or frequency, by looking at EEG data collected during long-term monitoring.

The primary function of functional mapping is to identify and map critical brain areas, such as motor or language regions, during surgery preparation.

Reassuring communication and providing clear information helps reduce patient anxiety by creating a sense of understanding and control during monitoring.

Sterilizing reusable electrodes according to facility infection prevention protocols prevents cross-contamination between patients, ensuring safety.

HIPAA ensures patient privacy and confidentiality by regulating the collection, use, and disclosure of Protected Health Information (PHI) during EEG monitoring.

Absence seizures are characterized by 3-Hz spike-and-wave discharges on the EEG, which are distinct from other seizure types.

A recording of brain electrical activity using electrodes placed on the scalp. It helps diagnose neurological conditions like epilepsy and brain disorders.

The primary purpose of archiving EEG data is to comply with legal and clinical requirements for data retention and accessibility.

A differential amplifier in EEG compares the voltage between two electrodes to create the EEG signal, which represents the difference in electrical potential between them.

If a patient experiences a seizure during monitoring, the most important action is to call for medical assistance and document the event. This ensures the patient receives immediate care and their medical history is recorded.

Impedance monitoring ensures signal quality and minimizes noise during the recording session by measuring the resistance between the electrode and the scalp.

Periodic lateralized epileptiform discharges (PLEDs) are a pattern of electrical activity in the brain that can be associated with various conditions including stroke, status epilepticus, and brain tumors.

Spike-and-wave discharges consist of sharp spikes followed by slow waves, commonly seen in generalized epilepsy.

Calibration ensures that the EEG equipment is functioning correctly and producing accurate data by verifying the machine's accuracy.

Hypoallergenic adhesives help reduce skin irritation and ensure successful electrode application, especially for patients with sensitive skin.

Periodic sharp wave activity in EEG is often seen in herpes simplex encephalitis, a viral infection of the brain.

The 10-20 system is a standardized method for placing electrodes on the scalp for EEG monitoring, ensuring consistency across different recordings.

Long-term video-EEG monitoring is crucial for accurate diagnosis of seizure types by providing a comprehensive record of electrical activity and corresponding behavior.

Alpha waves are most prominent in the EEG of a relaxed, awake adult with eyes closed, indicating a relaxed state of consciousness.

Proper grounding of EEG equipment minimizes 60 Hz interference (noise) from electrical sources, improving signal quality.

Functional brain mapping helps identify areas critical for language, motor, and sensory functions, avoiding damage during surgery.

Tonic seizures are characterized by sudden muscle stiffening and increased muscle tone.

A chaotic brainwave pattern seen in infants, often associated with severe seizures.

The main purpose of reporting critical values in EEG is to alert the care team to significant changes in the patient's brain activity.

A differential amplifier compares the voltage difference between two electrodes, amplifying the electrical signals in the brain.

Delta waves, characterized by slow, high-amplitude brainwaves, are common during deep sleep stages.

The first step in addressing artifacts during EEG recordings is to check the connections of the electrodes to ensure they are secure.

The 10-20 system is a widely used method for placing electrodes on the scalp, ensuring standardized and accurate readings during EEG.

Implanted devices can interfere with EEG signals, potentially making the recording difficult to interpret.

The American Board of Registered Electroencephalographic Technologists (ABRET) sets the ethical standards for EEG technologists.
