Regular impedance monitoring helps reduce noise and artifacts, resulting in clearer and more accurate recordings.

Delta waves are most prominent during deep sleep, characterized by slow and high amplitude waves.

Pediatric EEG requires specific recording parameters based on age to ensure correct interpretation.

HIPAA protects the confidentiality of patient information during EEG monitoring, similar to other healthcare settings.

Safety protocols prioritize the safety of both the patient and the technician during the EEG procedure.

The primary reason for long-term EEG monitoring is to identify and analyze seizure patterns in order to provide appropriate treatment.

The 10-20 system is the standard method used for placing electrodes on the scalp during EEG monitoring. It ensures consistency and accuracy in electrode placement.

A key step in preparing for EEG monitoring is reviewing the patient's medical history and the specific monitoring orders to tailor the procedure effectively.

Concept 4 in long-term EEG monitoring relates to understanding EEG frequencies, which helps in identifying different brain wave patterns and making accurate interpretations.

Calibration is essential to make sure the EEG equipment is working correctly and accurately capturing brain signals.

Muscle activity, usually caused by patient movement, is the most common type of artifact seen in EEG recordings.

Documenting clinical events, stimulations, and any changes in the EEG patterns is crucial for accurate interpretation and analysis of the recorded data.

EEG frequency analysis plays a vital role in distinguishing different types of brain activity and providing valuable diagnostic information.

Ensuring standardized and accurate electrode placement for EEG recording.

A chaotic EEG pattern found in infants with West Syndrome, characterized by high-amplitude slow waves and multifocal spikes.

The first step to troubleshoot EEG artifacts. It ensures valid recording by checking all electrode connections for tightness and proper placement.

A primary concern in EEG monitoring of patients with implanted devices like pacemakers or neurostimulators, as they can disrupt the EEG signals.

A federal law protecting patient's health information, ensuring privacy and confidentiality of medical records, including EEG data.

A procedure during EEG setup to measure the electrical resistance between the electrode and the skin, ensuring good contact for optimal signal acquisition.

The most common brainwave pattern in a relaxed, awake adult with eyes closed, appearing on the EEG as rhythmic, 8-12Hz waves.

A crucial safety protocol for reusable electrodes in EEG, preventing cross-contamination and ensuring patient safety.

A key purpose of long-term video-EEG monitoring, aiming to capture and accurately diagnose different types of seizures.

A technical procedure used to identify areas in the brain essential for language, motor control, and sensory functions.

An artifact commonly caused by loose electrode connections. It appears as a sudden change in the EEG signal.

The primary function of digital analysis in EEG monitoring, aiding in identifying spikes, seizure events, and other abnormalities in the brainwaves.

An important aspect of EEG monitoring that helps researchers understand the underlying electrical activity in the brain.

The organization responsible for setting ethical standards and certifying EEG technologists, ensuring professional conduct in the field and promoting patient safety.

The most common ictal pattern seen in temporal lobe epilepsy, characterized by rhythmic slow waves (theta waves) between 4-7Hz during seizures.

Periodic Lateralized Epileptiform Discharges (PLEDs) are temporary, abnormal electrical activity in the brain that can be seen on an EEG. They are often associated with conditions that affect brain function such as stroke, brain tumors, and status epilepticus.

Hyperventilation activation is a procedure used to induce brain activity and identify potential seizure activity in an EEG. Hyperventilation involves rapid, deep breathing that can trigger epileptiform discharges. Due to the potential risks, it should not be performed in patients with asthma, recent stroke, or cardiovascular disease.

Impedance checks are essential for ensuring that electrodes are properly placed and maintain a good connection with the skin to collect accurate brain activity during an EEG. Poor electrode placement can cause inaccurate readings and affect the quality of the recording.

EMG artifact is a type of noise in an EEG recording that is caused by muscle activity. It can appear as high-frequency noise on the signal. Proper grounding of the electrodes and techniques to reduce muscle tension can minimise EMG artifact.

ACNS or the American Clinical Neurophysiology Society provides guidelines that ensure safe and effective practices for long-term EEG monitoring. This includes things like proper electrode placement, infection control, and documentation of results for accurate interpretation.

Functional mapping in EEG monitoring involves identifying key brain regions, such as those responsible for motor function, language, and memory. This helps to understand which areas of the brain are critical and can be preserved during surgical procedures.

The 10-20 system is a standardised method for placing electrodes on the scalp during an EEG. The system is based on anatomical landmarks, ensuring that electrodes are positioned consistently and accurately.

Spike-and-wave complexes are a type of electrical activity seen in the brain during an EEG. These bursts of electrical activity can signify a generalized tonic-clonic seizure, a type of seizure with sudden muscle stiffening and jerking movements.

Trend analysis involves reviewing and analysing EEG data over time to identify patterns. This helps to identify changes in brain activity such as seizure onset, frequency, or progression of brain activity.

When using reusable electrodes, proper sterilization is critical in preventing infections and ensuring patient safety. Sterilization protocols should follow strict guidelines for cleaning and disinfection to ensure no pathogens remain, preventing the spread of disease.

A differential amplifier is an essential component of an EEG recording system. It compares the voltage differences between two electrodes to produce the EEG signal that is then amplified. This method helps to reduce noise and ensure that the signal is clear and accurate.

60 Hz interference is noise that originates from power lines and can be problematic in EEG recordings. Proper grounding of the EEG equipment is essential for reducing this interference and ensuring clear signals of brain activity.

Tonic seizures are a type of seizure characterized by sudden muscle stiffening and increased muscle tone. This causes a prolonged period of muscle contraction, often resulting in the body assuming an unusual posture.

Seizure provocation techniques are used to help identify potential seizure activity in an EEG. In this, procedures such as hyperventilation, sleep deprivation, or photic stimulation are used to trigger brain activity for diagnostic purposes.

The primary purpose of reporting critical values is to alert the care team to significant changes in the patient's condition as observed in the EEG recordings. This ensures a timely and appropriate medical response to address the patient's needs, potentially preventing worsening symptoms.
