Study Notes
EEG Monitoring: Key Concepts
- EEG Wave Patterns: Understanding the characteristics of different EEG wave patterns (e.g., alpha, beta, delta) is crucial for clinical diagnosis and long-term monitoring.
- EEG Frequency: EEG frequency analysis helps with detailed clinical diagnosis.
- Seizure Classification: Accurate seizure classification is vital for proper diagnosis and effective monitoring.
- Artifact Identification: Recognizing and mitigating artifacts (noise) is essential for accurate EEG recordings.
- Patient Preparation & Safety: Proper patient preparation, including electrode placement and potential risks from certain treatments, are critical for successful EEG monitoring.
- Post-Study Analysis: Post-study analysis creates reports to summarize findings for physician interpretation. Documentation of all relevant data points is critical.
- Patient Confidentiality: HIPAA (Health Insurance Portability and Accountability Act) is the governing law for maintaining patient confidentiality.
- Temporal Lobe Seizures: Hippocampal sclerosis is a common cause of temporal lobe seizures.
- Electrode Cleaning: Following facility infection control protocols is essential for electrode cleaning.
- Contraindications: Avoiding procedures like hyperventilation in patients with asthma, stroke, or cardiovascular disease is crucial.
- Electrode Application: Cleaning the scalp is the first step in electrode application to reduce artifacts.
Electrode Setup & Techniques
- Impedance Checks: Impedance checks are essential to ensure proper electrode contact and reduce noise in the signal.
- Muscle Artifacts: Muscle activity is a common cause of EMG artifacts.
- Long-Term Monitoring: Comprehensive documentation of stimulations, clinical events, and EEG changes is mandatory during long-term monitoring. ACNS guidelines provide safety protocols.
- Functional Mapping: Functional mapping is used to identify critical brain areas during pre-surgical evaluations.
- Patient Anxiety: Providing clear communication and reassurance helps manage patient anxiety.
- Electrode Placement Systems: The 10-20 system is a common system for non-invasive electrode placement.
- Invasive Electrodes: When using invasive electrodes, the utmost care must be taken to ensure safety, especially preventing infection and monitoring for tissue damage.
- Trending Analysis: Analyzing trends in EEG data over time can identify important patterns like seizure activity or frequency.
Artifacts, Seizures, and Safety
- Patient Movement: Muscle artifacts are often caused by patient movement.
- EEG Annotation: Marking clinical and electrographic events is crucial for thorough documentation.
- Reusable Electrode Handling: Properly sterilizing reusable electrodes according to facility infection prevention guidelines is vital.
- Seizure Events: Documenting a seizure event during monitoring and obtaining medical assistance are crucial, while recording the event is a critical task.
- Impedance Monitoring: Real-time impedance monitoring assures good signal quality.
- Calibration: Calibrating EEG equipment before each recording is essential for accurate results.
- Sensitive Skin: Use hypoallergenic adhesives for patients with sensitive skin.
- Specific Seizure Types & associated EEG Patterns:
- Absence Seizures: Characterized by 3 Hz spike-and-wave discharges.
- West Syndrome: Characterized by hypsarrhythmia.
- Artifact Reduction & Troubleshooting: Checking electrode connections is the first step in troubleshooting.
Equipment, Procedures, and Reporting
- Data Archiving: Archiving EEG data is crucial for meeting legal and clinical requirements, often dictated by regulatory bodies.
- Differential Amplifiers: Differential amplifiers compare voltages between electrodes to produce the EEG signal.
- Calibration: Calibration before each recording session ensures accuracy of instruments.
- Reporting Critical Values: Reporting critical values during EEG monitoring is essential to immediately alert relevant personnel.
- Calibration Procedures: Important for verification of EEG equipment for accurate signals, proper functioning, and reliable data. - Troubleshooting: Checking electrode connections is the first step in artifact troubleshooting.
- Electrode Placement: The 10-20 and 10-10 systems facilitate precise electrode placement.
- Implanted Devices: Knowing that implanted devices can interfere with EEG signals is crucial in patient care.
- Ethical Standards: ABRET establishes ethical guidelines and standards for EEG technologists.
