EEG system routine: Overview, Uses and Top Manufacturer Company

Introduction

EEG system routine refers to the clinical setup and standardized workflow used to perform a routine electroencephalography (EEG) recording—typically a time-limited, non-invasive assessment of the brain’s electrical activity using scalp electrodes. In hospitals and clinics, routine EEG is a foundational neurodiagnostic test that supports evaluation of seizures, altered awareness, encephalopathy, and other neurologic presentations, while also influencing operational decisions such as triage, escalation to continuous monitoring, and follow-up planning.

In many facilities, routine EEG is also referred to as a standard EEG or spot EEG, and it is commonly performed as a scheduled outpatient test or a same-day inpatient bedside study. While exact durations vary by protocol, a routine EEG is usually designed to be long enough to assess baseline background activity and reactivity, and—when feasible—to sample drowsiness or sleep to increase diagnostic yield. Some departments include optional synchronized video, while others use EEG-only acquisition to reduce complexity and storage requirements.

For learners, the EEG is where neurophysiology becomes visible: rhythms, reactivity, and artifacts are not just textbook concepts—they are signals that must be acquired safely and interpreted in clinical context. For administrators and biomedical teams, EEG services are a cross-functional program involving scheduling, trained personnel, infection prevention, device maintenance, data storage, and vendor support. Routine EEG also sits at the intersection of quality assurance (standard electrode placement, consistent technical settings, complete annotations) and service reliability (uptime, parts availability, technologist coverage, interpretation turnaround).

This article explains what an EEG system routine is, when and why it is used, how it is operated safely, how outputs are typically interpreted, what to do when problems occur, how cleaning is managed, and how the global market landscape varies by country—without providing medical advice or replacing local protocols, supervision, or manufacturer instructions for use (IFU).

What is EEG system routine and why do we use it?

An EEG system routine is the combination of medical equipment, trained workflow, and documentation used to record EEG in a standard clinical setting (often outpatient or short inpatient bedside studies). The core purpose is to capture and store brain electrical signals in a way that is accurate enough for clinical interpretation and safe enough for repeated use across many patients.

Clear definition and purpose

• EEG (electroencephalography) records voltage differences generated by synchronized activity in the cerebral cortex, detected at the scalp.
• A routine EEG is generally shorter and more standardized than prolonged video EEG monitoring or continuous EEG in the intensive care unit (ICU).
• The routine study aims to document:
• Baseline background activity and reactivity
• Intermittent abnormalities (e.g., slowing)
• Epileptiform discharges or seizures if they occur during the recording
  Interpretation and diagnostic conclusions are made by qualified clinicians according to local practice.

A practical way to think about EEG is that it offers very high temporal resolution (changes can be seen moment to moment), but more limited spatial precision compared with imaging. Scalp EEG primarily reflects summed activity from superficial cortical regions; deeper structures may be under-represented, and localization depends heavily on electrode coverage, montage, and signal quality. For routine EEG programs, the “purpose” is not only diagnosis—it is also risk stratification, documentation of baseline function, and deciding whether further monitoring (longer recordings, continuous EEG, or video correlation) is warranted.

Common clinical settings

Routine EEG studies are commonly performed in:

• Outpatient neurodiagnostic laboratories
• Emergency departments (rapid “spot” EEG access varies by facility)
• Inpatient wards for patients with altered mental status, suspected seizures, or encephalopathy
• ICU (as a screening or bridge to continuous EEG, depending on resources)
• Pediatric and neonatal units (often with age-specific protocols; device configuration varies by manufacturer)

Some hospitals also perform routine EEG in step-down or high-dependency units, and occasionally in procedure-adjacent areas when patients cannot be transported easily. From a hospital operations perspective, routine EEG is frequently a “high coordination” service because it intersects with bed management, transport, infection prevention, and time-sensitive interpretation.

Key benefits in patient care and workflow

A well-run EEG system routine can support:

• Timely neurodiagnostic assessment without moving the patient to imaging suites
• Bedside capability in many models (cart-based or portable systems)
• Standardized documentation that supports continuity of care and handoffs
• Efficient escalation pathways, such as referral for prolonged monitoring when needed (per local protocols)
• Remote review workflows in some facilities (tele-neurophysiology), dependent on privacy controls and infrastructure

Routine EEG can also serve as a baseline comparator for future studies (for example, comparing background organization before and after a clinical change), provided that technique is consistent and technical limitations are clearly documented. Benefits vary by clinical context, staffing, and equipment configuration.

Plain-language mechanism of action (how it functions)

In general terms:

1. Electrodes placed on the scalp detect tiny voltage changes (microvolt-range).
2. A headbox and amplifier boost and condition the signal while reducing noise.
3. The system filters and digitizes the signal and displays it as waveforms across channels.
4. Software applies a montage (the way channels are mathematically displayed) and allows annotation, review, and storage.
5. Optional modules (varies by manufacturer) include video, photic stimulation, or trend displays.

Because signals are small, EEG is highly sensitive to artifacts from muscle activity, movement, poor electrode contact, and electrical interference—making good technique and environment essential.

Behind the scenes, most modern systems use a differential amplifier: it compares two inputs and amplifies the difference while rejecting common noise (a concept often described as common-mode rejection). Signal quality is strongly influenced by electrode-skin contact (often assessed via impedance checks when available) and by how well leads are secured to reduce motion. Digitization quality also depends on system design choices such as sampling rate and analog-to-digital conversion; while these parameters are typically preconfigured to meet clinical needs, they still matter when evaluating platforms and troubleshooting noise.

How medical students typically encounter or learn this device in training

Medical students and residents usually meet the EEG in three ways:

• Foundational learning: neurophysiology (frequency bands, sleep stages, seizure concepts).
• Clinical exposure: neurology rotations, epilepsy clinics, ICU rounds, emergency evaluations for altered awareness.
• Skill-building: recognizing common artifacts, understanding why a “normal EEG” does not always exclude disease, and learning how EEG complements history and exam.

Importantly, operating the EEG medical device is typically performed by trained technologists; trainees often learn the workflow to improve ordering practices, communication, and interpretation literacy.

In practical training environments, learners also benefit from understanding what makes a routine EEG technically adequate: correct electrode placement, sufficient recording time, documented patient state (awake/drowsy/asleep), and clear notation of any activation procedures and artifacts. This helps trainees read EEG reports more critically and ask better follow-up questions (e.g., whether sleep was achieved, whether artifacts limited interpretation, or whether a longer study may be needed).

When should I use EEG system routine (and when should I not)?

Use of an EEG system routine should follow local protocols and clinician judgment. The points below describe common patterns of use and situations where a routine EEG may be insufficient or inappropriate as the first test.

Appropriate use cases (common examples)

Routine EEG is commonly considered when clinicians need objective information about cerebral electrical activity, such as:

• Suspected seizure or epilepsy evaluation, including characterization of events when history is unclear
• Assessment of altered mental status, encephalopathy, or unexplained reduced responsiveness
• Clarification of episodic symptoms (e.g., transient confusion) when seizure is a concern
• Follow-up assessment after a neurologic event when EEG findings could help refine differential diagnosis (context-dependent)
• Baseline documentation prior to changes in care pathways (varies by service line)

Whether a routine study is sufficient or whether prolonged/video/continuous monitoring is more appropriate depends on the clinical question, event frequency, and resource availability.

Operationally, “appropriate use” also depends on how the result will be used. A well-placed routine EEG order includes enough clinical context (e.g., time of last event, current medications that may affect alertness, whether the patient can cooperate, and any infection control precautions) so that the technologist can plan acquisition and the interpreting clinician can contextualize findings.

When it may not be suitable (or may be insufficient)

A routine EEG may be a poor fit when:

• The clinical question requires capturing infrequent events, where prolonged monitoring may have higher yield.
• The patient’s condition requires continuous monitoring for nonconvulsive seizures or evolving encephalopathy (common in ICU settings), and a routine snapshot may be inadequate.
• There is a need for sleep-focused diagnostics (a routine EEG is not the same as a polysomnography study, even though both can include EEG channels).
• Operational constraints (staffing, infection precautions, patient behavior) make a technically adequate study unlikely without additional planning.

It is also important to recognize that routine EEG is not a substitute for other urgent diagnostics when those are the priority in a given scenario. For example, clinicians generally avoid using EEG as a reason to delay time-sensitive stabilization, imaging, or treatment decisions; instead, EEG is integrated as one data source within the broader clinical workflow.

Safety cautions and general contraindication themes

EEG is non-invasive and generally well tolerated, but safety issues can arise from adjunct procedures and skin contact materials. Common caution areas include:

• Skin integrity concerns: open wounds, burns, or severe dermatitis at electrode sites (site selection and deferral decisions vary by protocol).
• Adhesive or gel sensitivity: some patients may react to prep gels, tapes, or collodion-type adhesives (materials vary by manufacturer and facility).
• Activation procedures: techniques such as photic stimulation or hyperventilation may have patient-specific risks and are not mandatory parts of every routine EEG. They should be performed only when ordered/approved by local practice and when staff are prepared to stop promptly if symptoms occur.
• Infection control precautions: contact precautions may change electrode selection (e.g., single-use consumables) and room workflow.

EEG is a passive recording modality, but the system is still hospital equipment connected to mains power. Electrical safety practices and equipment integrity checks remain essential.

In addition, some activation steps can create practical safety concerns even when physiologically tolerated—for example, a drowsy patient may be at increased falls risk when asked to change position or when transitioning off the bed after a quiet, darkened recording. Building in simple safeguards (bed rails per policy, staff presence during transfers, clear instructions not to stand abruptly) reduces preventable incidents.

Emphasize clinical judgment, supervision, and local protocols

• Ordering and performing an EEG system routine should be aligned with local policy, credentialing, and supervision requirements.
• Interpretation should be performed by appropriately trained clinicians, and results should be correlated with the clinical picture.
• If a routine EEG is being used as a “bridge” to a higher-acuity test (e.g., continuous EEG), escalation criteria should be locally defined to avoid delays.

What do I need before starting?

A safe and reliable EEG system routine depends on preparation across people, process, and equipment. Think in four buckets: environment, accessories, competency, and governance.

Required setup, environment, and accessories

Common requirements include:

• Environment
• Quiet room with controllable lighting (helps reduce muscle and movement artifacts)
• Access to a bed or recliner with safe positioning and fall prevention
• Minimized electrical interference (as feasible) and a plan for managing nearby equipment

• Privacy measures appropriate for patient dignity and any optional video recording

• Core accessories and consumables

• EEG electrodes (single-use or reusable, per policy)
• Conductive paste/gel, skin prep materials, measuring tape/marker
• Gauze, cotton swabs, adhesive/tape as applicable
• Gloves and cleaning/disinfection supplies approved by infection prevention
• Optional: electrode caps, additional channels (ECG, EOG), photic stimulator, and video module (varies by manufacturer)

In day-to-day operations, “what you need” also includes small but important enablers of quality: a way to secure leads so they do not tug (reducing electrode pops), a method to keep the patient comfortable for stillness (pillow support, blanket per policy), and a plan for hair-related barriers (dense hair, braids, hair products) that may require additional time and clear communication.

Training and competency expectations

Routine EEG quality is heavily operator-dependent. Common competency expectations include:

• Correct electrode placement method (commonly the International 10–20 system, if used by the facility)
• Artifact recognition and correction (movement, muscle, electrode issues, mains interference)
• Safe use of activation procedures when applicable and permitted
• Accurate documentation and annotation practices
• Privacy and data handling competence (logins, storage locations, access control)

Facilities often define competency by supervised cases, periodic reassessment, and adherence to standard operating procedures.

Some departments also incorporate inter-rater technical audits (e.g., periodic review of electrode placement accuracy, completeness of annotations, and impedance documentation) as a quality improvement tool. While the interpreting clinician focuses on clinical meaning, the technical layer determines whether the recording is even interpretable.

Pre-use checks and documentation

Typical pre-use checks include:

• Confirm the device has passed preventive maintenance and electrical safety checks (labels/stickers per local biomed practice).
• Inspect cables, connectors, and electrodes for damage, corrosion, or broken leads.
• Verify date/time, patient ID workflow, and storage destination in the acquisition software.
• Run an impedance check and/or system calibration step if your model supports it (varies by manufacturer).
• Ensure consumables are available and within facility policy (expiry checks if applicable).

Documentation commonly includes patient identifiers, indication (as ordered), technologist notes, state changes (awake/drowsy), activation procedures performed (if any), and any limitations that affect interpretability.

For portable systems, pre-use checks may also include confirming battery status (if the unit will be moved between rooms), verifying that the video feed (if used) is synchronized, and ensuring that required accessories (photic stimulator, extra electrodes, spare lead wires) are on the cart to prevent mid-study interruptions.

Operational prerequisites (commissioning, maintenance readiness, consumables, policies)

From a hospital operations lens, readiness includes:

• Commissioning/acceptance testing by biomedical engineering before clinical go-live
• A defined preventive maintenance schedule and service pathway (in-house vs vendor)
• Consumables management (electrodes, gels, wipes) with reorder triggers
• Policies for:
• Reuse vs single-use electrodes
• Cleaning and disinfection responsibilities
• Data retention, backup, and cybersecurity approvals (especially if networked)

Many facilities also define standard processes for file naming, data upload timing, and downtime documentation, because EEG recordings can be large and misfiled studies create both clinical risk and rework. Even where software is user-friendly, consistent governance reduces wrong-patient attachments and incomplete records.

Roles and responsibilities (clinician vs. biomedical engineering vs. procurement)

• Clinicians (ordering/reading): define clinical question, approve protocols, interpret results, and communicate implications.
• EEG technologists/nursing staff (performing): prepare the patient, acquire data, ensure documentation quality, and escalate safety concerns.
• Biomedical engineering: asset management, safety testing, repairs, preventive maintenance, and coordination with manufacturer service.
• IT/cybersecurity (where applicable): network integration, user access management, updates, storage, and downtime planning.
• Procurement: vendor evaluation, total cost of ownership, contract terms, consumables strategy, and service level requirements.

In mature programs, infection prevention and risk management may also be involved in decisions about reusable electrode reprocessing, single-use strategies for high-risk areas, and the practicalities of placing EEG equipment into isolation rooms without compromising cleaning workflows.

How do I use it correctly (basic operation)?

Workflows vary by model and facility, but most EEG system routine procedures follow a common sequence designed to protect patient safety and maximize signal quality.

Basic step-by-step workflow (commonly universal)

1. Confirm the order and patient identity – Verify patient identifiers per policy. – Review indication and any precautions (skin issues, infection control status, behavioral risks).

2. Prepare the environment and equipment – Position the EEG cart/portable unit safely. – Check power supply integrity and cable management (avoid trip hazards). – Confirm software login and correct patient data entry workflow.

3. Explain the procedure and set expectations – Use plain language: “We are recording brain electrical activity from the scalp.” – Set expectations about stillness, duration, and possible activation steps (if used locally).

4. Prepare the scalp and apply electrodes – Measure and mark electrode locations per local method (commonly 10–20). – Prep the skin to reduce impedance while protecting skin integrity. – Apply electrodes (cap, paste/gel, or adhesive method depending on your system and policy).

5. Connect leads and verify signal quality – Connect electrode leads to the headbox/amplifier. – Run impedance checks if available and adjust electrodes as needed. – Confirm each channel shows physiologic activity and not saturation or flatline.

6. Select montage and technical settings – Choose an appropriate montage (e.g., bipolar or referential), per facility practice. – Confirm filter settings and sensitivity are appropriate for routine acquisition. – Perform a calibration check if required by your protocol (varies by manufacturer).

7. Record baseline and state changes – Record awake baseline and note eye opening/closure as directed by protocol. – Document drowsiness or sleep transitions if they occur.

8. Perform activation procedures if ordered and permitted – Examples include photic stimulation or hyperventilation; use local safety criteria and stop rules. – Ensure the patient is monitored and supported during these steps.

9. Monitor artifacts and annotate events – Watch for common artifacts (movement, muscle tension, electrode pops, mains noise). – Correct technical issues during recording whenever possible. – Annotate any clinical events, symptoms, or technical interventions.

10. End the study and secure the data – Verify the recording is saved to the correct patient record and storage location. – Ensure required metadata and technologist notes are completed.

11. Remove electrodes and restore the patient – Remove electrodes gently, check the scalp, and clean residual gel per facility practice. – Provide general post-test instructions per local policy (e.g., hair washing guidance).

12. Turnover and readiness for the next patient – Clean/disinfect equipment per policy. – Restock consumables and report any equipment issues promptly.

In practice, the difference between a “routine EEG that helps” and a “routine EEG that frustrates everyone” often comes down to details within the steps above: consistent electrode placement, stable impedances, active artifact management, and real-time annotations that tell the reader what was happening (awake, talking, moving, drowsy, coughing, stimulation performed, etc.). For inpatient bedside studies, coordinating with nursing (timing around imaging, procedures, feeding, and medication administration) can also reduce interruptions and improve yield.

Typical settings and what they generally mean (non-brand-specific)

Exact parameters and defaults vary by manufacturer and protocol, but common concepts include:

• Sensitivity (gain): controls how large signals appear on screen; too high exaggerates noise, too low hides relevant activity.
• Time base (display speed): determines the time shown per page; affects pattern recognition.
• Filters: help reduce slow drift or high-frequency noise but can also distort waveforms if overused.
• Notch filter (mains interference): reduces 50/60 Hz electrical noise; use is protocol-dependent because it can affect waveform morphology.
• Montage selection: changes how channels are displayed and can help localize patterns or identify artifacts.

It can be helpful (especially for learners and new technologists) to remember that filters are often described functionally as high-pass (reducing very slow drift) and low-pass (reducing high-frequency activity). Even when filters make a tracing look “cleaner,” they may also remove clinically relevant information or change the appearance of sharp transients—one reason protocols typically define default settings rather than leaving them to individual preference.

Steps that often differ by model

• Wired vs wireless headboxes
• Integrated video vs EEG-only acquisition
• Electrode caps vs individual electrodes
• Cloud vs on-premises storage (dependent on facility governance and local regulations)
• Built-in impedance displays and automated quality indicators (varies by manufacturer)

Other differences that influence routine workflow include how the system handles patient demographic entry (manual entry vs worklist integration), how it manages event markers and annotations, whether it supports automatic montage changes during review, and what options exist for exporting or archiving studies during network downtime.

How do I keep the patient safe?

Patient safety with an EEG system routine is achieved through layered controls: preparation, monitoring, safe environment, and a culture that supports stopping the procedure when needed.

Safety practices and monitoring

Key practices commonly include:

• Identity and consent processes as defined locally (especially if video is used).
• Skin checks before and after electrode placement, documenting irritation or breakdown.
• Comfort and positioning to reduce movement artifacts and prevent falls (drowsiness is common during quiet recordings).
• Cable management to prevent entanglement and trip hazards.
• Emergency readiness appropriate to the setting (outpatient lab vs inpatient vs ICU).

If a patient experiences a clinical event during recording (for example, a seizure or a syncopal episode), the priority is always patient safety and immediate clinical response according to the setting’s emergency procedures. From a workflow perspective, clear role assignment—who stays with the patient, who documents, who calls for help—reduces confusion and supports accurate event annotation.

Electrical safety and device integrity

EEG systems are medical devices designed to record tiny signals safely, but basic electrical safety remains essential:

• Use only approved power supplies, isolation features, and accessories intended for the system.
• Do not use equipment with damaged cords, cracked housings, exposed conductors, or unreliable connectors.
• Keep liquids away from the headbox/amplifier and connectors unless the IFU explicitly permits exposure.
• Follow biomedical engineering guidance on routine safety checks and labeling.

In complex bedside environments (ICU rooms with multiple pumps, ventilators, warming devices, and chargers), electrical noise and grounding issues are common operational challenges. Good safety practice includes not improvising with unapproved adapters or extension cords and escalating recurring issues to biomedical engineering rather than repeatedly working around them.

Activation procedures and human factors

When activation procedures are part of local routine:

• Use clear stop rules (symptoms, distress, or clinician direction).
• Monitor patient tolerance and ensure appropriate supervision.
• Document what was performed and any patient responses.

Human factors matter: fatigue, interruptions, and time pressure increase error risk. Simple controls—checklists, standardized naming conventions, and consistent electrode labeling—help prevent wrong-patient records or incomplete documentation.

Follow facility protocols and manufacturer guidance

• Always follow the manufacturer IFU for electrode types, cleaning limits, and approved accessories.
• Follow facility policies for infection prevention, patient monitoring responsibilities, and documentation standards.
• For networked systems, comply with access controls and data handling requirements.

Incident reporting culture (general)

Encourage reporting of:

• Near misses (wrong patient selected in software, mislabeled montage)
• Device malfunctions (intermittent channel dropouts, repeated impedance failures)
• Patient adverse events (skin injury, distress during activation procedures)

Reporting supports system learning and may be required under local medical device incident frameworks.

How do I interpret the output?

Routine EEG produces data that are clinically meaningful only when interpreted by trained clinicians and correlated with the patient’s presentation. This section explains what the output looks like and why interpretation is nuanced.

Types of outputs/readings

Common outputs from an EEG system routine include:

• Raw EEG waveforms displayed across multiple channels over time
• Montage-based views (bipolar, referential, or other configurations per local practice)
• Event annotations (patient symptoms, eye opening/closure, activation procedures, technologist interventions)
• Optional (varies by manufacturer):
• Synchronized video
• Quantitative displays (e.g., spectral trends) intended as adjuncts rather than standalone conclusions

Depending on the platform and facility workflow, the final output may also include a printed or exported report, a technologist worksheet, and—where implemented—structured data elements that support quality metrics (for example, whether activation procedures were performed, whether sleep was achieved, and reasons for technical limitations).

How clinicians typically interpret routine EEG

Clinicians commonly assess:

• Background activity: frequency, amplitude, organization, and symmetry
• Reactivity: changes with eye opening, stimulation, or state transitions
• Sleep features: if drowsiness or sleep occurs (stage-related patterns)
• Focal or generalized slowing: may reflect diffuse or localized dysfunction in the right context
• Epileptiform discharges: patterns such as spikes or sharp waves, interpreted cautiously
• Electrographic seizures: if captured during the recording

The final report typically integrates EEG findings with the clinical question and notes technical limitations (artifact burden, incomplete activation steps, limited cooperation).

Interpretation is also inherently age- and state-dependent. What is expected in an awake adult differs from what is expected in a drowsy patient, a sedated ICU patient, or a neonate. Even within routine EEG, details such as whether the patient reached light sleep, whether eyes were open or closed, and whether the recording was interrupted by talking or movement can meaningfully change what patterns are present and how confidently they can be interpreted.

Common pitfalls and limitations

Routine EEG is powerful but not definitive:

• False negatives: A patient with epilepsy may have a normal interictal routine EEG, especially if no events occur during the study.
• False positives/overcalls: Benign variants and artifacts can mimic epileptiform activity.
• State dependence: Drowsiness, sleep deprivation, and medications can change the EEG appearance, complicating interpretation.
• Short sampling window: A routine study may not capture intermittent abnormalities.

Another limitation is that EEG findings can be nonspecific: for instance, generalized slowing may reflect many different systemic or neurologic processes, and a technically limited study may reduce confidence in subtle findings. This is why operational documentation (what the patient was doing, how much artifact occurred, whether impedances were acceptable) is not “extra”—it is part of what makes the recording clinically usable.

Artifacts and why they matter

Artifacts are among the most common reasons a routine EEG becomes difficult to interpret. Frequent sources include:

• Eye movements/blinks (often frontal slow deflections)
• Muscle activity (EMG) (high-frequency “fuzzy” signals)
• ECG contamination
• Movement and cable sway
• Electrode pop from poor contact or drying paste
• Mains interference (50/60 Hz), often from nearby equipment or grounding issues

A strong EEG system routine includes robust annotation and corrective action so the interpreting clinician can distinguish physiologic signal from noise.

Other artifacts that technologists and readers often encounter include sweat artifact (slow baseline drift), pulse artifact (rhythmic movement at an electrode near a vessel), and chewing or talking artifact (rhythmic EMG bursts). Recognizing these patterns—and noting when the patient was speaking, chewing, or repositioning—can prevent misinterpretation and reduce unnecessary repeat studies.

What if something goes wrong?

Even a well-run EEG service will encounter technical and operational problems. A structured response protects patients, preserves data integrity, and reduces downtime.

Troubleshooting checklist (practical and non-brand-specific)

• Confirm patient safety first; stop any activation procedure if distress occurs.
• Check electrode contact and repeat impedance checks if available.
• Re-prep the skin and reapply the electrode if a channel is noisy or intermittent.
• Verify the reference and ground connections are secure and appropriate for the montage.
• Look for mains interference sources: nearby chargers, infusion pumps, warming devices, bed motors, or poor cable routing.
• Reduce movement and muscle artifact with repositioning, comfort measures, and clear instructions.
• Confirm filter settings have not been inadvertently changed from protocol defaults.
• If software is unresponsive, follow your facility’s downtime procedure (save/export if possible, document the interruption).
• If the recording is saved to a network location, confirm connectivity and storage permissions.

A useful practical distinction is whether the problem affects one channel (often an electrode/contact issue) versus many or all channels (often reference/ground, amplifier connection, or environmental electrical noise). For intermittent faults, gently stress-relieving or repositioning a suspect lead can help identify broken wires or loose connectors, but any damaged accessory should be removed from service and tagged per local biomedical policy.

When to stop use

Stop the EEG system routine and escalate if:

• The patient has significant distress, unexpected clinical deterioration, or safety concerns.
• There are signs of electrical hazard (smoke odor, heat, sparking, fluid intrusion near powered components).
• You cannot maintain a safe environment (falls risk, agitation without adequate staffing).
• The device behavior suggests malfunction that could compromise safety or data integrity.

When to escalate to biomedical engineering or the manufacturer

• Biomedical engineering: repeated channel failures, broken connectors, damaged headbox, failing electrical safety checks, battery/power issues, or recurrent unexplained noise across studies.
• Manufacturer/vendor support: persistent software errors, update failures, licensing issues, or problems requiring proprietary parts/tools.

Escalation pathways and response times should be defined in service agreements and local policy.

Documentation and safety reporting expectations (general)

• Document what happened, when, and what corrective actions were taken.
• Record the device identifier/serial number per asset management policy.
• Use internal incident reporting systems for malfunctions or patient safety events, as required by facility governance and local regulations.

Infection control and cleaning of EEG system routine

Cleaning and disinfection are not “afterthoughts” for EEG services; they are core quality and safety processes that protect patients and staff while preserving equipment lifespan.

Cleaning principles

• Clean before disinfecting: remove visible soil so disinfectants can work effectively.
• Use only facility-approved disinfectants that are compatible with the device materials.
• Avoid excess moisture near connectors, ports, and the headbox unless explicitly permitted by the manufacturer IFU.
• Separate “clean” and “dirty” workflows to prevent cross-contamination.

In EEG, cleaning challenges are often less about large surfaces and more about small interfaces: electrode cups, lead ends, cap connectors, and strain-relief areas where residue can accumulate. Consistent technique and adequate drying time help prevent corrosion, intermittent connections, and premature cable failure.

Disinfection vs. sterilization (general)

• Disinfection reduces microbial load on noncritical surfaces (typical for EEG electrodes contacting intact skin).
• Sterilization is intended to eliminate all microbial life and is usually reserved for devices entering sterile tissue. Routine scalp EEG typically does not require sterilization, but policies vary by facility and patient population.
• Reusable electrode handling requirements vary widely; follow the manufacturer IFU and infection prevention policy.

Many facilities apply a risk-based approach aligned with device-contact classification (e.g., intact skin vs compromised skin) and local infection prevention guidance, which may differ between outpatient labs and high-acuity inpatient units.

High-touch points to prioritize

Common high-touch surfaces include:

• Headbox exterior and lead bundles
• Electrode connectors and strain relief areas
• Keyboard, mouse/trackpad, touchscreen surfaces
• Cart handles and drawer pulls
• Photic stimulator handpiece and cables (if used)
• Patient chair rails, bed controls near the EEG cart during bedside studies

Example cleaning workflow (non-brand-specific)

• Perform hand hygiene and don gloves per policy.
• Remove and discard single-use consumables appropriately.
• Wipe down high-touch surfaces with approved disinfectant, ensuring the required contact time.
• For reusable electrodes: pre-clean per IFU, then disinfect using the approved method, rinse/dry if required, and inspect for damage.
• Allow components to dry fully before storage or reuse.
• Document cleaning if required by your facility’s traceability policy.

Follow manufacturer IFU and facility infection prevention policy

Compatibility is a recurring issue: some disinfectants can degrade plastics, cloud screens, or embrittle cables over time. When in doubt, treat the IFU as the primary source and align it with infection prevention requirements.

Medical Device Companies & OEMs

Understanding how manufacturers and OEMs operate helps hospitals evaluate support, quality systems, and lifecycle risk for complex hospital equipment like EEG platforms.

Manufacturer vs. OEM (Original Equipment Manufacturer)

• A manufacturer is the entity that markets the finished medical device under its brand and typically holds responsibility for regulatory documentation, labeling, and post-market support (definitions vary by jurisdiction).
• An OEM may produce components (e.g., amplifiers, sensors) or even a complete system that is sold under another company’s brand, depending on the business arrangement.
• OEM relationships can affect:
• Spare part availability and lead times
• Service training pathways (vendor-only vs shared service)
• Software update cadence and cybersecurity patching responsibilities
• Warranty terms and what is considered an “authorized” repair

For buyers, it is operationally important to confirm who provides service, who owns software updates, and how long parts are expected to remain available—details that vary by manufacturer and contract.

When evaluating an EEG platform specifically, many hospitals also look beyond the amplifier itself and assess the full “system routine” ecosystem: electrode and consumable availability, training resources, ease of cleaning, compatibility with isolation workflows, and the vendor’s ability to support multi-site deployments with consistent configurations.

Vendors, Suppliers, and Distributors

Even when hospitals select a specific EEG platform, most day-to-day operational success depends on the supply chain: electrodes, gels, replacement leads, and timely service escalation.

Role differences: vendor vs. supplier vs. distributor

• A vendor is the selling entity (often a manufacturer or reseller) providing the device or consumables under contract terms.
• A supplier provides goods and may be focused on consumables (electrodes, prep materials) or services.
• A distributor typically holds inventory, manages logistics, and may offer value-added services such as installation coordination, warranty handling, and first-line technical support.

In many countries, an “authorized distributor” is critical for warranty validity and access to certified service tools—details that should be confirmed during procurement.

From an operations perspective, the “best” distributor is often the one that can reliably provide consistent SKUs, clear substitution rules (what can be swapped without changing clinical workflow), and predictable lead times for high-failure components like patient lead wires and connectors.

Key Takeaways and Practical Checklist for EEG system routine

• Define the clinical question clearly before scheduling an EEG system routine.
• Confirm local protocol: routine EEG differs from prolonged and continuous EEG.
• Verify patient identity using your facility’s two-identifier standard.
• Check infection control status early to plan electrodes and room workflow.
• Inspect cables, connectors, and headbox housings for damage before use.
• Confirm preventive maintenance labeling per biomedical engineering policy.
• Ensure the acquisition software date/time and patient record are correct.
• Use only manufacturer-approved accessories and compatible electrodes.
• Prepare the environment to reduce noise: lights, comfort, and minimal interruptions.
• Manage cables to reduce trip hazards and motion artifact.
• Document baseline patient state: awake, drowsy, or asleep when observed.
• Use consistent electrode placement methodology per facility standard.
• Prioritize skin integrity during prep; avoid overly aggressive abrasion.
• Run impedance checks if available; correct poor contacts early.
• Choose montage and settings according to protocol, not personal preference.
• Treat notch filter use as protocol-driven because it can alter morphology.
• Annotate all state changes, symptoms, and technical interventions in real time.
• Monitor for common artifacts and correct them during acquisition when possible.
• Perform activation procedures only if ordered/approved and safe for the patient.
• Stop activation steps immediately if the patient becomes distressed or unstable.
• Save recordings to the correct patient file and verified storage destination.
• Maintain data privacy: logins, access controls, and secure workstations.
• Include clear technologist notes on limitations and artifact burden.
• Remove electrodes gently and reassess skin before the patient leaves.
• Clean then disinfect high-touch surfaces using approved products and contact times.
• Do not immerse components unless the manufacturer IFU explicitly allows it.
• Dry reusable electrodes fully before storage to reduce corrosion and failure.
• Keep a consumables par level to prevent cancellations and delays.
• Establish a downtime plan for software failures and network outages.
• Escalate repeated technical faults to biomedical engineering promptly.
• Document malfunctions with device ID/serial number for traceability.
• Build a culture of reporting near misses to improve system reliability.
• Evaluate service contracts based on response time, parts availability, and training.
• Confirm who the legal manufacturer is when OEM relationships are involved.
• Plan cybersecurity and update responsibilities for network-connected systems.
• Align procurement with staffing reality; the best device fails without trained users.
• Standardize room setup and checklists to reduce variation and rework.
• Use routine EEG results only with clinical correlation and qualified interpretation.
• Treat “normal routine EEG” as a limited snapshot, not a universal rule-out.
• Track turnaround time, repeat-study rates, and downtime as quality indicators.
• Ensure ongoing competency assessment for technologists and supervised trainees.
• Include infection prevention and biomedical engineering in equipment selection.
• Design workflows that work in both outpatient labs and bedside inpatient use.
