Here's an analysis of the provided text regarding the acceptance criteria and study for the SEDLine Sedation Monitor:
It's important to note that this document is a 510(k) summary for a medical device and not a detailed clinical study report. Therefore, some of the requested information, particularly regarding the specifics of clinical trials (like sample sizes for a test set, expert qualifications for ground truth, MRMC studies, and detailed training set information), is not present. The provided text primarily focuses on demonstrating substantial equivalence to a predicate device through technical similarities and compliance with safety standards, rather than extensive clinical performance data specific to diagnostic accuracy or reader improvement.
Acceptance Criteria and Reported Device Performance
The document doesn't explicitly state quantitative acceptance criteria for clinical performance (e.g., minimum sensitivity or specificity targets with confidence intervals). Instead, it highlights the device's technical specifications and adherence to safety and performance standards as the basis for equivalency.
The "Test Results" section broadly states: "The following tests have been conducted in order to verify and validate the device: software, mechanical and electrical validation testing and EMC testing." It then lists compliance with several UL, CSA, and IEC standards for electrical safety and electromagnetic compatibility. This implies that the 'acceptance criteria' are primarily related to meeting these technical and safety standards, as well as demonstrating that the device functions as intended for monitoring EEG signals and calculating the PSI.
Given the information, here's a table summarizing what can be inferred:
Acceptance Criteria Category | Specific Acceptance Criteria (Inferred from text) | Reported Device Performance |
---|---|---|
Safety | Compliance with recognized electrical safety standards. | UL 60601-1, CSA 22.2 No. 60601-1, IEC 60601-1, IEC 60601-2-26 |
Electromagnetic Compatibility (EMC) | Compliance with EMC standards. | FDA Reviewer Guidance for Premarket Notification Submissions, Section 7, Electromagnetic Compatibility dated November 1993 |
Functional Performance | Ability to acquire and display real-time EEG waveforms. Ability to process EEG data using digital signal processing. Ability to display processed EEG data in various formats. Ability to archive real-time or processed EEG data. Automatic self-tests upon power-up. PSI algorithm accurately converts EEG into a proprietary index related to anesthetic effects. | (Implied by device description and intended use) "The monitor provides signal processing and display capabilities for the 4 channels of real-time EEG data... calculates the processed parameters and displays the real-time EEG data and processed data." "Performs automatic self tests upon power up." "The PSI is an EEG variable that is related to the effect of anesthetic agents." |
Software Validation | Software functions as intended and is validated. | "software... validation testing" |
Mechanical Validation | Mechanical components function as intended and are validated. | "mechanical... validation testing" |
Electrical Validation | Electrical components function as intended and are validated. | "electrical validation testing" |
Predicate Equivalence | Similarities in function, processed parameters, PSI, self-tests, materials, and electrode locations to the predicate device. | All "Similarities" listed in the text (see below). |
Similarities to Predicate Device (part of the equivalence argument):
- Both systems are EEG monitors.
- Both systems provide processed parameters (EMG, SR, ART, PSI).
- Both systems include PSI, a proprietary computed EEG variable related to anesthetic effects.
- Both conduct self-tests at startup.
- Both electrodes use the same materials.
- Both electrodes collect data from the same electrode locations.
Study Information
Based on the provided text, a detailed clinical study report proving specific diagnostic performance metrics (like sensitivity, specificity, or reader improvement) is not included. The document describes the device and its technical validation for substantial equivalence purposes.
-
Sample size used for the test set and the data provenance:
- Not specified. The document mentions "software, mechanical and electrical validation testing and EMC testing," but does not detail any clinical test set or its sample size.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable/Not specified. There is no mention of a clinical test set requiring expert-established ground truth in this document.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable/Not specified. No clinical test set requiring adjudication is described.
-
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No such study is mentioned or implied. The SEDLine Sedation Monitor provides a Patient State Index (PSI) as a computed EEG variable related to anesthetic agents, not an AI that assists human readers in interpreting images or data. The device itself is the 'AI' portion (the PSI algorithm), providing a quantitative output.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Yes, implicitly. The PSI algorithm within the SEDLine monitor would function in a standalone manner to compute the PSI value from EEG signals. The output (the PSI number, EMG, SR, ART values, and EEG waveforms) is then presented to the human clinician. The "performance" in this context is the accuracy and reliability of these computed values in reflecting the brain state as intended. The document states the PSI "is related to the effect of anesthetic agents," implying its ability to provide this standalone metric.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not explicitly stated for the PSI algorithm's "ground truth." For devices that measure a physiological state (like depth of anesthesia), ground truth is typically correlated with clinical outcomes, pharmacokinetic/pharmacodynamic studies of anesthetic agents, and expert clinical assessment of patient response to simulation scenarios. The statement "The PSI is an EEG variable that is related to the effect of anesthetic agents" suggests that its development and validation would have involved correlating PSI values with known anesthetic concentrations/doses and their clinical effects, but the specifics are not in this document.
-
The sample size for the training set:
- Not specified. There is no mention of a training set size for the PSI algorithm. Algorithm development often involves data sets for training, but this is not detailed in a 510(k) summary focused on substantial equivalence.
-
How the ground truth for the training set was established:
- Not specified. Similar to the point above, the method for establishing ground truth for any potential training data used for the PSI algorithm is not described.

The Physiometrix PSArray² EEG Electrode is applied directly to the patient's skin to enable recording of electrophysiologic signals (such as EEG).
The Physiometrix Model 4310, PSArray² EEG Electrode, is a single-use, disposable, pre-gelled electrode array. The PSArray² is comprised of six (6) electrodes located at F7, Fp1, FpZ', FpZ, Fp2 and F8. The electrode is packaged with 1 electrode per pouch, 25 pouches per box and 4 boxes per case. The electrodes are mounted in a polyethylene foam coated with a pressure sensitive adhesive. The electrode pad is an area of silver/silver chloride ink that is connected to cable connector by a silver ink trace. An electrolyte gel is held in place over the electrode pad by a open-cell polyurethane sponge located in wells created by the foam basepad. The electrolyte gel was selected for its low impedance properties. No pre-application prepping is required to achieve adequate impedance levels for operation of the PSA4000. The PSArray² EEG Electrode is connected to the PSA4000 System via a patient cable that attaches to the substrate connector. The PSArray² is designed for use with the PSA4000 System.
The provided text is a 510(k) summary for the Physiometrix Model 4310 PSArray² EEG Electrode. This submission focuses on establishing substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria in the way a new, high-risk device might. The "acceptance criteria" here are largely met by demonstrating compliance with recognized standards and similarity to the predicate.
Here's an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria (Standard / Test) | Reported Device Performance |
---|---|

It is intended to monitor the state of the brain by real-time data acquisition and processing of EEG signals. The system includes the Patient State Index (PSI™), a proprietary computed EEG variable that is related to the effect of anesthetic agents.
The PSA4000 is an EEG monitor designed for use in the OR, ICU, EEG laboratory and for clinical research. It provides the ability to acquire and display real-time EEG waveforms, process the real time EEG data using digital signal processing techniques, display the processed EEG data in several different formats, and archive the real-time or processed EEG data for future review. The PSA4000 consists of three main components, the monitor, the amplifier and the archive media (optional). The device performs automatic self tests upon power up to ensure that the monitor and its components are functioning properly.
The provided text describes a 510(k) premarket notification for the "PSA4000 EEG Monitor with Frontal PSI." However, it does not contain a detailed study with specific acceptance criteria and performance data for the device in the way a clinical trial report would.
The document primarily focuses on demonstrating substantial equivalence to a predicate device (PSA4000 EEG Monitor with PSI K001069) and fulfilling regulatory requirements. It mentions general validation testing but lacks the quantitative details to complete the requested table and answer many of the specific questions about clinical study design and outcomes.
Here's a breakdown of what can be extracted and what is missing, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
This information is not provided in the document. The document states:
"The test results are all positive and indicate that the device meets product requirements and satisfies customer needs and expectations."
However, it does not specify what those "product requirements" or "acceptance criteria" were in a measurable format, nor does it present quantitative performance data. The tests mentioned are:
- Software validation testing
- Mechanical validation testing
- Electrical validation testing
- EMC testing
- Compliance with UL 2601, CSA 22.2 No. 601-1, IEC 601-1, IEC 601-2-26, and FDA Reviewer Guidance for Premarket Notification Submissions (EMC).
2. Sample size used for the test set and the data provenance
- Sample Size: Not specified. The document mentions "test results" but does not detail the number of subjects, cases, or data points involved in any testing, particularly for the performance of the "Frontal PSI" component.
- Data Provenance: Not specified. There is no information about the country of origin of the data or whether the data was retrospective or prospective.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not specified. This information is typically relevant for studies evaluating the accuracy of a diagnostic or prognostic tool against expert judgement. The document does not describe such a study.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not specified. As no expert- Adjudicated test set is detailed, no adjudication method is mentioned.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No MRMC study was mentioned. The device is an EEG monitor that calculates a "Patient State Index (PSI)". The document does not describe studies where human interpretation of EEG or patient state was compared with and without the aid of the PSA4000's PSI.
6. If a standalone (i.e., algorithm only without human-in-the loop performance) was done
While the device calculates a proprietary "Patient State Index," the document does not provide a standalone performance evaluation of this algorithm in terms of specific metrics (e.g., sensitivity, specificity, accuracy) against a reference standard. The "Test Results" section refers to engineering and compliance testing, not clinical "standalone" performance.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
Not specified. Due to the lack of detailed performance studies, the type of ground truth used to validate the accuracy or effectiveness of the PSI is not mentioned.
8. The sample size for the training set
Not applicable/Not specified. The document does not describe the use of machine learning in a way that typically involves distinct "training" and "test" sets for algorithmic development in the context of diagnostic accuracy. The PSI is described as a "proprietary computed EEG variable," implying an algorithm, but no details of its development or training are given.
9. How the ground truth for the training set was established
Not applicable/Not specified. See point 8.

System for recording electroencephalogram of brain electrical activity to Host Digital EEG Machine.
The NeuroLink NeuroMonitoring System (predicate device) consists of a set of components that work together to acquire and present EEG signal to any existing EEG recording and analysis equipment. The components include Biosensor electrodes, e-Net headpiece, Patient Module, battery module, fiber optic cable, and DSP Interface Card. Changes in the Patient Module and power supply are described in this submission. An electrode headbox has been added to the Patient Module and an AC power supply is available as an alternate to the battery module. The Patient Module is a small battery powered or AC powered amplifier. The EEG signals are transmitted from the head via conventional electrodes that are input into the attached headbox or e-Net that has a mating connector on the patient module. Power is enabled when the Patient Module is plugged into the DSP Card via the fiber optic cable, the host digital EEG computer is in the powered state and the Patient Module is enabled by pressing the control button located on the Patient Module. A five meter fiber optic cable is standard. The fiber optic cable provides patient isolation and flexible patient EEG Record Station placement options. Self test, calibration and impedance tests are remotely activated from the Host Digital EEG Machine through the DSP Interface Card or locally by depressing the appropriate test button on the Patient Module. A visual indication of control button function, system status and out of range impedance can be provided on the LCD display as controlled from the Host Digital EEG Machine.

preserving the full fidelity of the original EEG waveform data in the EEG patient population while providing tools for displaying and printing EEG waveforms for review and interpretation by trained health care professionals.
The Equinox™ Digital EEG System incorporates products produced by Physiometrix and Neuro Concepts to provide a superior system for EEG recording that provides cost benefits to the user. The Equinox™ System features several Physiometrix products including the Biosensor electrodes, e-Net headpiece. Patient Module, fiber optic cable and DSP Interface Card and computer hardware. The last component of the system is the Neuro Concepts software described in K905435B UNIQUANT'M System. The Equinox™ is an EEG system that offers a choice of paper or paperless approaches to reading of EEG records and automatic archival of EEG data onto optical disks. The highest priority of the system is to ensure the quality of the EEG data acquisition and storage thus preserving the full fidelity of the raw analog EEG waveform for reproduction onto paper or for display on a computer monitor. EEG data that is acquired on the Equinox™ System is always archived directly onto optical disk with no means available to the system operator to modify or process the raw digitized data.
The provided text describes the Physiometrix Equinox™ Digital EEG System, but it does not contain information related to specific acceptance criteria, a study proving device performance against those criteria, or the detailed aspects of a clinical study (like sample sizes, ground truth establishment, or expert involvement).
The document is a 510(k) Premarket Notification summary, which focuses on establishing substantial equivalence to predicate devices. It emphasizes maintaining the fidelity of EEG data acquisition, storage, and display compared to existing systems.
Here's a breakdown of why the requested information cannot be extracted from the provided text:
- No Acceptance Criteria: The document does not list quantitative or qualitative acceptance criteria that the device had to meet (e.g., accuracy percentages, sensitivity, specificity, or specific performance metrics for EEG signal quality).
- No Performance Study Details: While the document states the system ensures "quality of the EEG data acquisition and storage" and "preserves the full fidelity of the original EEG waveform data," it doesn't describe an actual study conducted to demonstrate this. There are no reported device performance numbers.
- Focus on Substantial Equivalence: The text primarily argues that the Equinox™ System has the "same intended use" and "basic functionality" as its predicate devices (K930080 HydroDot NeuroMonitoring System and K905435B UNIQUANT™ System). This is a regulatory argument for market clearance, not a summary of a clinical performance study with defined acceptance criteria.
- "Minor Concern" Classification: The document refers to the FDA Draft Reviewer Guidance for Computer Controlled Products and classifies the software as having "minor concern" because there is "no risk or danger to the patient" even with inadvertent misuse. This speaks to safety, not diagnostic or interpretive performance.
Therefore, I cannot populate the table or answer the specific questions about sample sizes, experts, adjudication, MRMC studies, or standalone performance because this information is not present in the provided 510(k) summary.
The document is a regulatory submission aimed at demonstrating equivalent technology and safety, not a detailed report of a performance study against specific, measurable criteria.

The NeuroLink NeuroMonitoring System has the same intended use as the predicate device, the HydroDot NeuroMonitoring System. Both are designed to locate EEG electrodes according the 10-20 International System and present electrical signal sensed by the electrodes from the skin to existing EEG recording, analysis and archiving equipment.
The e-Net NeuroMonitoring System consists of a set of components that work together to acquire and present EEG signal to any existing EEG recording and analysis equipment. The components in the original submission included Biosensor electrodes, e-Net headpiece, Patient Module, fiber optic interface, Monitor Module, AC power supply, and EEG Adapter Cable. The components of this submission include Biosensor electrodes, e-Net headpiece, Patient Module, fiber optic interface, and DSP Interface Card (replaces Monitor Module). The AC power supply and EEG Adapter Cable have been eliminated.
The modified system discussed in this submission uses the same electrodes and headpiece for signal acquisition but has changes in the modules used to transmit signals to the existing EEG recording and analysis equipment.
The Patient Module is a small battery powered unit attached to the patient. Power is enabled when the Patient Module is plugged into the DSP Card via the fiber optic cable, the host digital EEG computer is in the powered state and the Patient Module is enabled by pressing the control button located on the Patient Module. A five meter fiber optic cable is standard. The fiber optic cable provides outstanding patient isolation and flexible patient EEG Record Station placement options. A connector located at the top end of the module attaches to our standard e-Net headpiece or optionally a mini-jack for interface to standard cup electrodes. Self test, calibration and impedance tests are remotely activated from the host Digital EEG Machine through the DSP Interface Card or locally by depressing the appropriate test button on the Patient Module. A visual indication of control button function, system status and out of range impedance can be provided on the LCD display as controlled from the host Digital EEG Machine.
This submission report describes a device where EEG signal is acquired and presented to existing EEG recording and analysis equipment. The submission is not related to a machine learning system.

Instead, the device is a hardware system for acquiring and transmitting EEG signals. The performance evaluation focuses on the functional equivalence to a predicate device.
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Functional equivalence to predicate device (K930080, HydroDot NeuroMonitoring System) | The modified system uses the same electrodes and headpiece for signal acquisition but has changes in the modules used to transmit signals. The Patient Module and DSP Interface Card (replacing Monitor Module) perform similar functions as the predicate device's components for signal transmission and interfacing with EEG recording equipment. The system aims to acquire and present EEG signals according to the 10-20 International System, identical to the predicate device's stated function. |
Elimination of AC power supply and EEG Adapter Cable while maintaining functionality | The AC power supply and EEG Adapter Cable have been eliminated, implying the new system achieves intended functionality without these components. |
Outstanding patient isolation and flexible patient EEG Record Station placement | Provided by a five-meter fiber optic cable. |
Remote and local activation of self-test, calibration, and impedance tests | Remotely activated from the host Digital EEG Machine through the DSP Interface Card or locally by depressing the appropriate test button on the Patient Module. |
Visual indication of control button function, system status, and out-of-range impedance | Provided on the LCD display as controlled from the host Digital EEG Machine. |
