The provided text describes a 510(k) summary for the Ambu Neuroline Ground electrode. It is a submission for a medical device seeking clearance based on substantial equivalence to existing legally marketed predicate devices. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are not in the context of clinical performance metrics like sensitivity or specificity. Instead, they refer to the demonstration of substantial equivalence to predicate devices through non-clinical testing.
Here's a breakdown of the requested information based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Demonstration of Substantial Equivalence) | Reported Device Performance |
|---|---|
| Electrical Functionality: Equivalent electrical characteristics to predicate devices. | Laboratory tests performed to ensure electrical functionality. |
| Mechanical Functionality: Equivalent mechanical characteristics to predicate devices. | Laboratory tests performed to ensure mechanical functionality. |
| Biocompatibility: Device is biocompatible. | Biocompatibility of the electrode has been established. |
| Safety and Effectiveness: As safe and effective as predicate devices. | Concluded that the device has equivalent electrical and mechanical functionality, meets mandatory performance standards, and is as safe and effective as the predicate devices. |
| Aging Test Performance: Maintained performance over time. | Aging tests were performed. |
2. Sample Size used for the test set and the data provenance
- Sample Size for Test Set: Not explicitly stated. The document mentions "laboratory tests" and "aging test" but does not quantify the number of electrodes or test cycles used.
- Data Provenance: Not explicitly stated, but the tests are described as "laboratory tests" implying they were conducted in a controlled environment by the manufacturer (Ambu A/S). There is no mention of country of origin of data or whether it was retrospective or prospective in a clinical sense.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not applicable. For this type of device and 510(k) submission, "ground truth" is not established by clinical experts in the way it would be for diagnostic algorithms. The ground truth here is derived from the established performance and safety profiles of the predicate devices, against which the new device's engineering and material properties are compared.
- Qualifications of Experts: N/A.
4. Adjudication method for the test set
- Adjudication method: Not applicable. There was no clinical study involving human interpretation or adjudication. The non-clinical tests likely involved objective measurements and comparisons to pre-defined engineering specifications or performance metrics of the predicate devices.
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
- MRMC Study: No, an MRMC comparative effectiveness study was not conducted. This is an electrode device, not an AI or imaging diagnostic tool.
- Effect Size of Human Readers: Not applicable.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Standalone Performance: Not applicable. This is a physical medical device (an electrode), not an algorithm or software. There is no "algorithm only" performance to evaluate.
7. The type of ground truth used
- Type of Ground Truth: The "ground truth" for this submission is the established performance and safety characteristics of the legally marketed predicate devices. The new device aims to demonstrate substantial equivalence to these existing devices through comparison of technological characteristics and non-clinical test results. In essence, the predicate devices are the "ground truth" for what is considered safe and effective for this product type.
8. The sample size for the training set
- Sample Size for Training Set: Not applicable. As this is a physical medical device and not an AI/ML algorithm, there is no "training set."
9. How the ground truth for the training set was established
- Ground Truth for Training Set: Not applicable.

Not Found
This document is a 510(k) premarket notification from the FDA for a medical device called the "Ambu® SPUR® II Adult Single Patient Use Resuscitator." This type of document is a regulatory approval, not a scientific study report describing the performance of an AI/ML device against acceptance criteria. Therefore, the requested information (acceptance criteria, study details, sample sizes, expert qualifications, etc.) is not present in this document.
The document states that the device is "substantially equivalent" to legally marketed predicate devices, which is the basis for its approval. This substantial equivalence is assessed based on design, materials, and intended use, rather than a detailed performance study with acceptance criteria and ground truth as would be reported for an AI/ML diagnostic device.
Therefore, I cannot provide the requested table and information based on the provided text.

Ambu General Purpose Disposable ECG Electrodes are intended for use in all Standard ECG Applications. Electrodes are made for single patient use only.
Not Found
This is a 510(k) premarket notification for a medical device (Ambu Disposable ECG Electrode) and as such, it does not typically contain detailed studies with acceptance criteria and performance metrics in the same way a clinical trial report would for a novel device. The primary purpose of a 510(k) is to demonstrate substantial equivalence to a legally marketed predicate device.
Therefore, many of the requested fields cannot be directly answered from the provided text. However, I can extract the information that is present and explain why other information is not available.
Here's a breakdown based on the provided document:
1. A table of acceptance criteria and the reported device performance
This document (510(k) summary) does not include a direct table of acceptance criteria and reported device performance for a study. The 510(k) process primarily relies on demonstrating substantial equivalence to a predicate device, which usually involves comparing design, materials, indications for use, and performance characteristics. The performance is typically demonstrated through bench testing and often, but not always, limited clinical testing, which are then compared to the predicate device's known performance. The specific performance data and criteria would be in the full submission, not usually in the publicly available summary.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not available in the provided document. A 510(k) summary typically doesn't detail the sample size or provenance of specific test data unless it's a critical part of demonstrating substantial equivalence for a novel aspect. It's likely that a variety of bench tests were performed on a sample of electrodes, but specifics are not mentioned.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable/available. For an ECG electrode, ground truth for performance is established through objective electrical and biocompatibility testing (e.g., impedance, adhesion, irritation) against established standards or predicate device performance, not typically by expert review of "truth" in the same way an imaging AI algorithm would be.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable/available. Adjudication methods are typically used in studies where human interpretation of medical data is being evaluated, such as in imaging or clinical diagnoses. For an ECG electrode, objective test results are generally compared to pre-defined thresholds or predicate device results.
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
Not applicable. MRMC studies, especially those involving AI assistance, are relevant for diagnostic devices that interpret complex data, such as imaging. An ECG electrode is a passive measurement device; it doesn't "interpret" data in a way that would involve human readers or AI assistance in this context.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. There is no algorithm in the "Ambu Disposable ECG Electrode" to perform standalone analysis. It is a physical device used to acquire physiological signals.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for an ECG electrode would generally refer to specific performance metrics established through validated testing methods, such as:
- Electrical Performance: Impedance, DC offset, combined offset instability, defibrillation overload recovery (as per ANSI/AAMI EC12:2000 standard).
- Adhesion: Adhesion strength over time.
- Biocompatibility: Absence of cytotoxicity, irritation, sensitization (as per ISO 10993 standards).
These "ground truths" are verified through standardized bench tests and potentially limited human use studies for skin irritation, but not through expert consensus on diagnostic interpretation or pathology, as the device doesn't make a diagnosis. The document does not specify which of these were used or the details of the testing.
8. The sample size for the training set
Not applicable. This device does not use an algorithm that requires a "training set" in the machine learning sense.
9. How the ground truth for the training set was established
Not applicable. As there is no training set for an algorithm, there is no ground truth established for it.

The Ambu® Blue Sensor MRX electrode is applied to the surface of the body to transmit the electrical signal at the body surface to a processor in order to produce an electrocardiogram or vectorcardiogram. The electrode is designed for use in MR environment, therefore the electrode is MR safe, and for X-ray purposes, therefore the electrode is x-ray translucent. The electrode is for single patient use only.
Each electrode consists of a foam material with an adhesive to be mounted on the patient. The sensor element consists of a foil furnished with a conductive carbon filled polymer snap and a Ag/AgCl sensor point. On top of the sensor point a sponge is positioned filled with a wet gel that conducts the signal from the patient further on to the electrode. The choise of materials ensures a non-ferromagnetic electrode which makes it x-ray translucent and MR safe. The electrodes are delivered on a foil sheet with 8 electrodes and 32 electrodes are packed in a laminated foil pouch. The electrode is non sterile and intended for single use.
This 510(k) summary does not contain the detailed study information needed to fully address all parts of your request. It mainly describes the device and claims substantial equivalence to a predicate device. However, I can extract the available information and highlight what is missing.
Here's a breakdown based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
This document does not explicitly state specific acceptance criteria in a quantitative manner (e.g., Sensitivity > X%, Specificity > Y%). Instead, it relies on demonstrating substantial equivalence to a predicate device and adherence to a general standard.
| Acceptance Criterion (Implicit) | Reported Device Performance |
|---|---|
| Substantial Equivalence to Predicate Device (K983689) | The MRX electrode is "almost identical with the SUPAtab electrode." The main change is the metal snap on the SUPAtab has been changed to a carbon-filled polymer snap on the MRX. Both electrodes have the same Ag/AgCl sensor material and the same materials except for the snap. The FDA reviewed the 510(k) and "determined the device...is substantially equivalent." This implies the performance is considered comparable enough for its intended use. |
| MR Safety | The choise of materials ensures a non-ferromagnetic electrode which makes it...MR safe. |
| X-ray Translucency | The choise of materials ensures a non-ferromagnetic electrode which makes it x-ray translucent. |
| Adherence to AAMI EC12 2000 standard | Both electrode types meet the AAMI EC12 2000 standard. (This standard likely outlines performance requirements for ECG electrodes, such as impedance, DC offset, amplitude response, etc., but the specific values are not detailed in this document.) |
| Intended Use: Transmit electrical signal for ECG/vectorcardiogram in MR environment (new for MRX) | "The Ambu® Blue Sensor MRX electrode is applied to the surface of the body to transmit the electrical signal at the body surface to a processor in order to produce an electrocardiogram or vectorcardiogram." The device is "designed for use in MR environment, therefore the electrode is MR safe, and for X-ray purposes, therefore the electrode is x-ray translucent." The FDA's substantial equivalence determination implies that it performs this function acceptably in the specified environment. |
| Single Patient Use | The electrode is for single patient use only. (This is a design characteristic, not a performance metric per se, but it's part of the product specification.) |
| Shelf Life of 2 years | Both electrode types… have a shelf life of 2 years. (This would typically be confirmed through stability testing, but the details are not provided here.) |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify a "test set" in the context of clinical performance evaluation with a numerical sample size. The substantial equivalence argument primarily relies on material changes and adherence to a standard, rather than a clinical trial with a defined test set.
- Sample Size: Not specified for a performance test set.
- Data Provenance: Not applicable in the context of a "test set" for clinical evaluation. The comparison is primarily in vitro based on materials and design, and in silico regarding MR safety and X-ray translucency.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable. This submission concerns a medical device accessory (ECG electrode) and relies on technical specifications and substantial equivalence, not a ground truth established by medical experts for a diagnostic performance study.
4. Adjudication Method for the Test Set
Not applicable, as a test set for clinical performance requiring adjudication is not described.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No, an MRMC comparative effectiveness study was not done or described in this 510(k) summary. This type of study is more common for diagnostic imaging algorithms where human readers' performance with and without AI assistance is evaluated.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
No, a standalone performance study in the context of an algorithm is not discussed. This device is an electrode, not a standalone diagnostic algorithm. Its performance is tied to its physical properties and ability to reliably transmit an electrical signal according to industry standards.
7. Type of Ground Truth Used
The "ground truth" for this device, implicitly, is:
- Physical and material properties: Ensuring non-ferromagnetic characteristics for MR safety and X-ray translucency.
- Adherence to AAMI EC12 2000 standard: This standard sets performance benchmarks for ECG electrodes (e.g., impedance, offset voltage, noise) which are considered "ground truth" for electrical signal transmission quality.
- Substantial equivalence to the predicate device: The predicate device (SUPAtab) has an established history of safe and effective use, so matching its performance in critical aspects serves as a form of "ground truth."
8. Sample Size for the Training Set
Not applicable. There is no "training set" as this device is not a machine learning algorithm.
9. How the Ground Truth for the Training Set was Established
Not applicable. As there is no training set for an algorithm, there is no ground truth established for it.
