Loose electrodes can cause electrode pop artifacts, which appear as sudden spikes on EEG recordings, potentially affecting data interpretation.

If impedance checks reveal high resistance, reapplying and securing electrodes ensures proper contact and reduces noise in the EEG recording.

Alpha waves are characteristic of the posterior dominant rhythm in relaxed, awake individuals.

Creutzfeldt-Jakob Disease is often associated with periodic sharp wave discharges in EEG recordings.

Activation procedures like hyperventilation and photic stimulation are used to provoke epileptiform activity for diagnostic purposes.

Rhythmic theta activity is often observed in temporal lobe epilepsy during seizures.

Archiving ensures long-term accessibility and compliance with legal and clinical data retention requirements.

Delta waves are prominent during deep sleep and are associated with restorative processes.

HIPAA requires patient information to remain confidential and accessible only to authorized personnel.

Impedance monitoring ensures proper electrode function and reduces noise for accurate recordings.

Myoclonic seizures are defined by brief, shock-like muscle jerks.

Pediatric EEG requires age-appropriate parameters for accurate diagnosis and interpretation.

Annotations record significant events and observations, aiding in the interpretation of EEG data.

Proper cleaning and disinfection are critical to prevent cross-contamination and infections.

Adjusting electrode placement can resolve high-frequency noise caused by poor electrode contact.

Sawtooth waves are characteristic of REM sleep and indicate active brain activity during dreaming.

Caused by poor contact between the electrode and the scalp, it appears as abrupt deflections on the EEG, resembling a 'pop'.

The brain structure most commonly affected in temporal lobe epilepsy, often due to a condition called hippocampal sclerosis.

Documenting all clinical and electrographic events during EEG monitoring. It's like a detailed record of everything that happens.

The most common artifact in ICU EEG recordings, often originating from medical devices like ventilators or heart monitors.

Often used for patients with status epilepticus, this prolonged monitoring helps assess seizure activity and its patterns over a longer period.

Evaluates the quality of the EEG signal by measuring the resistance between the electrode and the scalp, helping to minimize noise.

Amplifies the difference between electrical signals from two electrodes, producing the EEG waveform. It's the heart of EEG recording.

A hallmark pattern in EEG, often seen in generalized epilepsy, characterized by a sudden spike followed by a slower wave pattern.

A chaotic and high-amplitude EEG pattern, characteristic of West Syndrome, a severe form of epilepsy in infants.

A digital tool that helps identify spikes, seizures, and other EEG patterns automatically, aiding in the interpretation process.

The critical step when a seizure occurs during EEG monitoring. Document the seizure details and immediately alert the medical team.

The most common artifact in EEGs of awake patients, caused by muscular activity, it appears as irregular waves on the EEG.

A crucial safety protocol during invasive EEG monitoring, involving sterile techniques to prevent infection during electrode placement and care.

Documentation of significant EEG findings, ensuring the medical team is aware of critical information that needs immediate attention.

Characterized by sharp, symmetrical, and fast waves, these are often associated with REM sleep and may be linked to vivid dreams.

Grounding the EEG setup properly reduces electrical interference from medical devices like pacemakers, ensuring a clear and accurate recording.

Provoking seizure activity helps diagnose epilepsy by revealing abnormal brain activity patterns. These techniques can help determine the type and location of seizures.

If a patient experiences a seizure during EEG monitoring, the care team is notified immediately and the event is documented for further analysis.

This pattern of brain activity, characterized by periodic sharp wave complexes, is a major sign of Creutzfeldt-Jakob Disease, a rare and fatal brain disorder.

Activation procedures like hyperventilation and photic stimulation are used to provoke epileptiform discharges, revealing potential abnormalities that may not appear during normal recordings.

Electrical interference, caused by devices like cellphones or medical equipment, is a common problem in long-term EEG recordings, making data analysis more complex.

HIPAA guidelines are crucial for protecting patient privacy and confidentiality in all healthcare settings, including EEG monitoring. It enforces strict rules for handling medical information.

Muscle activity, often related to clenching teeth, can contaminate the EEG signal, making it difficult to interpret true brain activity.
