The VELA Ventilator is intended to provide continuous or intermittent respiratory support in an institutional health care environment (e.g. hospitals) for individuals who require mechanical ventilation. The ventilator is a restricted medical device intended for use only by qualified trained personnel under the direction of a physician. It may be used on adult and pediatric patients. Specifically, the ventilator is applicable for adult and pediatric patients weighting at least 5 kg (11lb), who require the following types of ventilation support, as prescribed by an attending physician.
- Positive pressure ventilation
- Assist / control, SIMV, or CPAP modes of ventilation
The ventilator is suitable for use in institutional and transport settings. It is not intended of use in an emergency medical transport ventilator or for home care applications.
A VELA with the CO2 monitoring option is intended to monitor the effectiveness of ventilation. It may be used on adult and pediatric patients. It is suitable for use in a hospital critical care environment, and is a restricted medical device intend for use by qualified trained personnel under the direction of a physician.
The VELA Series Ventilator is a modified Tbird Ventilator and like its predecessor, is an easy to use, self-contained, servo-controlled, software-driven ventilator. It has a dynamic range of breathing gas delivery that provides for pediatric through adult patients. Its revolutionary user interface module provides maximum flexibility with simple operator interaction. It has a flat panel color LCD with real time charting and digital monitoring capabilities, a touch screen for easy interaction, membrane keys and a dial for changing settings and operating parameters. A precision gas delivery turbine with servo controlled active inhalation and exhalation improves performance over previous generations.
The VELA Series Ventilator may be configured as a conventional ventilator or non-invasive positive pressure ventilator (NPPV). It is easy to clean and its design does not allow liquids to pool on the casing, reducing the likelihood of fluid leakage into the body of the ventilator.
The VELA Series Ventilator base model comes with comprehensive features for the critical care environment. Optional features can be added at time of purchase or at a later date.
The provided text describes the VELA Ventilator and its intended use, but it does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria in terms of accuracy or clinical effectiveness.
The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices rather than proving a device meets specific quantitative performance targets against a defined acceptance criterion.
Here's what can and cannot be extracted from the provided text according to your request:
1. A table of acceptance criteria and the reported device performance
- Not Available: The document does not specify any quantitative acceptance criteria or reported device performance metrics in the way you've outlined (e.g., sensitivity, specificity, accuracy against a gold standard). The "Summary of Testing and Validation" states, "In Summary Performance testing verified that the VELA Ventilator meets it's performance requirements and that this device is substantially equivalent to predicate medical devices currently legally marketed in the United States." This is a general statement and does not provide specific criteria or results.
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: The document does not describe a clinical test set, its sample size, or data provenance. The validation seems to be based on performance testing to ensure it meets requirements for substantial equivalence, not a clinical study with a "test set" in the context of AI/diagnostic device performance.
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/Not Available: Since there is no described test set or study involving "ground truth" establishment by experts (as would be for an AI or diagnostic device), this information is not provided.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable/Not Available: As above, no such 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
- Not Applicable/Not Available: The VELA Ventilator is a mechanical ventilator, not an AI-assisted diagnostic or imaging device. Therefore, an MRMC study or assessment of human reader improvement with AI assistance is not relevant or included.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable/Not Available: The device is a ventilator, a mechanical medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Not Applicable/Not Available: Ground truth as typically defined for diagnostic or AI devices is not relevant to the information provided about this mechanical ventilator. The "ground truth" in this context would likely be the accurate delivery of ventilation parameters as measured by engineering tests.
8. The sample size for the training set
- Not Applicable/Not Available: As a mechanical device, there is no "training set" in the machine learning sense.
9. How the ground truth for the training set was established
- Not Applicable/Not Available: As above, there is no training set mentioned.
In summary: The provided document is a 510(k) summary for a ventilator, focusing on demonstrating substantial equivalence to existing predicate devices. It describes the device, its intended use, and indicates that performance testing was conducted to verify it meets its requirements. However, it does not detail specific acceptance criteria, study methodologies, or performance metrics in the format typically required for diagnostic or AI-based devices.
§ 868.5895 Continuous ventilator.
(a)
Identification. A continuous ventilator (respirator) is a device intended to mechanically control or assist patient breathing by delivering a predetermined percentage of oxygen in the breathing gas. Adult, pediatric, and neonatal ventilators are included in this generic type of device.(b)
Classification. Class II (performance standards).
