This document, a 510(k) summary for the VC150 Vital Signs Monitor, does not contain specific acceptance criteria or details of a study proving the device meets those criteria in the way a performance study for an AI-powered diagnostic device would.
The VC150 is a vital signs monitor, and the 510(k) submission primarily focuses on demonstrating substantial equivalence to predicate devices, rather than establishing de novo performance metrics through a clinical study with detailed acceptance criteria for an AI algorithm.
However, based on the information provided, here's what can be extracted and inferred, along with what is explicitly stated as not applicable or not available:
Acceptance Criteria and Device Performance
The document does not explicitly present a table of acceptance criteria and reported device performance in terms of diagnostic metrics (e.g., sensitivity, specificity, AUC) because it's a vital signs monitoring device subject to substantial equivalence, not an AI-driven diagnostic.
Instead, acceptance is implied by compliance with voluntary standards and successful non-clinical testing. The "reported device performance" is essentially that it functions comparably to predicate devices for its intended physiological measurements.
| Feature/Parameter Tested | Acceptance Criteria (Implied) | Reported Device Performance (Implied) |
|---|---|---|
| Blood Pressure (NIBP), Pulse Rate, Temperature, SpO2, SpCO, SpMet, SpHb, Respiration Rate | Demonstrates functionality and accuracy comparable to established predicate devices and relevant voluntary standards (e.g., ISO, AAMI for NIBP, SpO2). | Device is able to perform these measurements using approved modules (GE SuperSTAT/Classic, GE TruSignal, Nellcor OxiMax, Masimo Rainbow SET, Welch Allyn SureTemp, Exergen TemporalScanner) and functions as intended for its specified patient populations (adult, pediatric, neonatal). The document states the device is "as safe and effective and performs substantially equivalent as the following predicate devices." |
| System Functionality | Meets established requirements, risk management activities, and passes design verification, system integration, system verification/validation, performance, safety, and usability testing. | All listed testing activities were successfully completed, demonstrating the device works as specified and is safe for its intended use. |
| Compliance with Standards | Adherence to relevant voluntary standards (e.g., electrical safety, EMC, performance standards for vital signs monitoring). | The VC150 and its applications comply with voluntary standards as detailed in this premarket submission. |
Study Details (Based on available information)
-
Sample size used for the test set and the data provenance:
- Test Set Sample Size: Not explicitly stated as a single "test set" in the context of a clinical performance study. The 510(k) relies on non-clinical testing and substantial equivalence. Device performance would have been verified through various technical and bench tests, likely using specific test fixtures, simulated conditions, and potentially a small number of human subjects for usability or specific sensor validation, but this is not detailed.
- Data Provenance: Not applicable in the context of a large-scale clinical dataset. The evaluation method is non-clinical.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. Ground truth for physiological measurements in non-clinical testing is typically established by reference measurement devices or validated simulators, not human experts in the sense of a diagnostic consensus.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. No multi-reader adjudication method would be used for non-clinical verification of a vital signs monitor.
-
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. This is a vital signs monitor, not an AI-assisted diagnostic imaging device. An MRMC study is not relevant to this device type.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Yes, in a way. The performance of the various measurement algorithms (NIBP, SpO2, etc.) intrinsic to the device would have been evaluated in a "standalone" fashion (i.e., the device performing the measurement and displaying the result) during non-clinical verification. This is inherent to testing any medical device's core functionality.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the physical measurements (BP, SpO2, temp): Ground truth would be established through calibrated reference devices, validated physiological simulators, or direct comparison with accepted clinical gold standards in controlled, often bench-top or limited human subject, testing environments. For example, a non-invasive blood pressure module would be tested against an invasive arterial line or a highly accurate reference oscillometric device. Oxygen saturation would be tested against co-oximetry in blood samples.
-
The sample size for the training set:
- Not applicable. This device is not described as having an AI algorithm that requires a "training set" in the machine learning sense. The underlying physiological measurement algorithms (e.g., oscillometric NIBP algorithms, pulse oximetry algorithms) are well-established, rule-based, or traditionally coded algorithms, not typically "trained" on large datasets in the modern AI paradigm.
-
How the ground truth for the training set was established:
- Not applicable, as there is no stated AI "training set." The ground truth for the development of the predicates' algorithms (which are then incorporated or used as benchmarks) would have been established historically through clinical studies specific to those technologies.
In summary: The provided document is a 510(k) clearance letter and summary for a vital signs monitor, not a performance study for an AI-powered diagnostic device. The evaluation pathway for this device type focuses on substantial equivalence to existing predicate devices and compliance with recognized performance standards, primarily through non-clinical testing. Therefore, many of the requested details regarding acceptance criteria and performance studies in the context of AI are not present in this type of submission.
