Intended Use

The device is to be used by properly trained personnel to deliver emergency, short term, constant flow - pressure cycled ventilatory support.

Device Description

The VORTRAN Automatic Resuscitator (Model VAR-Plus) provides constant flow pressure cycled ventilatory support. The primary working mechanism of the VAR-PLUS is the Modulator which is an exhalation valve that opens at a set PIP (Peak Inspiratory Pressure) pressure and closes at a lower PEEP (Positive End Expiratory Pressure) pressure. During inhalation, exhalation will not start until the peak pressure is reached. During exhalation, inhalation will not begin until the pressure drops to PEEP. The rest of the VAR-PLUS consists of the Patient Connector Tee used to supply a flow of gas, entrain additional air, and provide a redundant pop-off valve

AI/ML Overview

The provided document is a 510(k) summary for the VORTRAN Automatic Resuscitator (VAR-Plus), a Class II medical device. It details the device's characteristics, intended use, and substantial equivalence to predicate devices, but it does not contain information about clinical studies measuring specific performance metrics against acceptance criteria.

The document explicitly states "Clinical Tests: None" and "Adverse S & E: None." Instead, the submission relies on in vitro testing and comparison to existing standards and predicate devices to demonstrate substantial equivalence.

Therefore, many of the requested items cannot be extracted directly from this document.

Here's a breakdown of what can and cannot be answered:

1. A table of acceptance criteria and the reported device performance

The document does not provide a table of acceptance criteria with corresponding device performance metrics. It refers to two standards/guidances that define performance and safety requirements:

  • "FDA Draft Emergency Resuscitator Equivalency Guidance" 14 April 1993 868.5925 Powered Emergency Ventilator (Resuscitator) BTL
  • "Standard Specification for Minimum Performance and Safety requirements for Resuscitators Intended for Use with Humans", ASTM Designation: F 920 - 93 (Reapproved 1999) An American National Standard.

However, the specific acceptance criteria from these documents and the VAR-Plus's reported performance against them are not detailed in this 510(k) summary. It only states that the device "meets" these standards. The device's operational characteristics are described qualitatively:

Operational CharacteristicReported Device Performance (Qualitative)
Gas Flow InputUp to 40 L/min
Automatic Delivery (50 PSIG source)40 L/min (667 mL/second)
Peak Pressure (PIP)Adjustable from 10 to 45 cm H2O
PEEPTypically 1/5th of PIP
Inspiratory TimeAdjustable over a wide range
RateAdjustable over a wide range
Air Entrainment ValveAllows patient to entrain additional air and respond to demand (pressure support)
Redundant Pop-off ValveRelieves pressure at 60 cm H2O

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Not applicable, as no clinical tests were performed. The "in vitro testing" mentioned is not detailed in terms of sample size or methodology.

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, as no clinical tests requiring expert-established ground truth were performed.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable, as no clinical tests requiring adjudication were performed.

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. This device is a mechanical resuscitator, not an AI or diagnostic imaging device that would typically undergo MRMC studies with human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The device itself is a standalone mechanical resuscitator. However, "standalone performance" in the context of typical AI/diagnostic device evaluation refers to the algorithm's performance without human intervention, which is not relevant here. The device's performance, as a mechanical product, was evaluated through in vitro testing against standards.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not applicable for clinical studies. The "ground truth" for the in vitro testing would be the specifications and requirements outlined in the referenced FDA Guidance and ASTM Standard. Compliance was likely verified through physical measurements and observations during bench testing.

8. The sample size for the training set

Not applicable, as this is a mechanical device, not an AI/machine learning algorithm requiring a training set.

9. How the ground truth for the training set was established

Not applicable, as this is a mechanical device, not an AI/machine learning algorithm.

510(k) Summary
13.OperationalCharacteristicsThe VAR-PLUS runs on a continuous flow of gas of up to 40 L/min. When connected to a 50 PSIG high flow source, the VAR-PLUS will automatically deliver 40 L/min (667 mL/second). Peak pressure may be adjusted from between 10 and 45 cm H2O and PEEP is typically 1/5th of PIP. Inspiratory time and rate are adjustable over a wide range. The VAR-PLUS is equipped with an air entrainment valve which allows the patient to entrain additional air and respond to the demands of the patient (pressure support). The VAR-PLUS is also equipped with a redundant pop-off valve that relieves pressure at 60 cm H2O.
14.ClinicalApplicationThe VAR-PLUS provides short term, pressure cycled, constant flow ventilatory support using either pressure control or pressure support. In the pressure support mode, the rate dial of the VAR-PLUS is set so that the baseline pressure is above the set PEEP allowing the patient to initiate inhalation by drawing the baseline pressure down to the set PEEP. The VAR-PLUS is not an ICU stand alone ventilator with multiple monitoring features. Set up and use of the VAR-PLUS is simple. Set desired flow and adjust pressure dial to obtain desired I-time and/or tidal volume (see tidal volume chart in instructions), and adjust rate dial to obtain desired rate and I to E ratio.
15.Clinical TestsNone
16.Adverse S & ENone

Information

17.Conclusion

The VAR-PLUS is substantially equivalent to a predicate device: the RespirTech PRO and Oxylator EM-100. The VAR-PLUS meets the FDA Draft "Emergency Resuscitator Guidance" and the "Standard Specification for Minimum Performance and Safety ,Requirements for Resuscitators Intended for Use with Humans" ASTM Designation: F 920 - 93 and has been shown to be/safe and effective.

Dear Mr. Lee:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
