The VORTRAN Manometer is a single patient use device intended to provide visual indication of a patient's airway pressure during ventilation from 0 to 60 cm-H2O. It may be attached to the manometer port on ventilation devices such as resuscitators, resuscitation bags, hyperinflation bags, CPAP Masks or CPAP Circuits.
The VORTRAN Pressure Manometer provides pressure readings from a breathing circuit in the range of 0 to 60 cm-H2O. The pressure readouts are approximate with an accuracy of ±2 cm-H2O for a low pressure range from 0 to 20 cm-H2O; ±3 cm-H2O for a pressure range of 20 to 40 cm-H2O; and ±5 cm-H2O for pressures above 40 cm-H2O. The manometer design requirements include: the pressure range of 0 to 60 cm-H2O, connection to a breathing circuit via a 22 mm male-female adaptor, and having a life expectancy as a single patient multiple use device. It accommodates connections through the option of a 22 mm tee or 15 mm port. The manometer includes a translucent enclosure that allows the pressure indicator needle to be seen from all sides.
The manometer label has three color zones of green, yellow, and red to give enhanced visual support during ventilation. The color coded scale indicates the following: green is 0 to 20 cm-H2O; yellow is 20 to 40 cm-H2O, and red is for pressures above 40 cm-H2O. The color coded scale is only for visual support and the correct ventilation pressure must be determined by the medical professional.
The provided document describes the VORTRAN Manometer, an airway pressure monitor, and its substantial equivalence to predicate devices. It does not contain information about a study proving the device meets acceptance criteria for an AI/ML powered device, nor does it detail a clinical trial or performance evaluation with statistical metrics such as sensitivity, specificity, or AUC, as would be typical for such devices.
The document primarily focuses on:
- Device Description: The VORTRAN Manometer provides visual indication of airway pressure from 0 to 60 cm-H2O.
- Technological Characteristics Comparison: A comparison of the VORTRAN Manometer's technology (pressure barrier, counter force, method of translating in-line air pressure, indicator mechanism, indicator movement, pressure limits, display increments, color coding, operating & storage temp) against several predicate devices.
- Performance Data: The performance data section explicitly states "Animal Study: None" and "Clinical Studies: None." It only mentions "The VORTRAN Manometer will indicate airway pressure with an indicator needle..." and describes its mechanical operation.
- Biocompatibility Testing: References to material compatibility with previously cleared devices.
- Compliance with Performance Standards: Adherence to ISO 5356-1 for conical connectors.
Therefore, most of the requested information regarding acceptance criteria and a study proving an AI/ML device meets them cannot be extracted from this document. This typically indicates a 510(k) pathway for a traditional medical device, not an AI/ML-powered device. The "performance data" section in this document refers to bench testing of the mechanical performance, not a clinical trial or AI model validation.
However, based on the information provided, I can construct a partial response:

A table of acceptance criteria and the reported device performance:
Acceptance Criteria Reported Device Performance Functionality: Visual indication of airway pressure Met: The VORTRAN Manometer is intended to provide visual indication of a patient's airway pressure. The indicator needle shows PIP and PEEP in cm-H2O, associated with a linear rack and pinion gear tied to a moveable diaphragm. (Performance Data section) Pressure range from 0 to 60 cm-H2O Met: The device provides pressure readings from 0 to 60 cm-H2O. (Device Description, Performance Data section) Accuracy: ±2 cm-H2O for 0 to 20 cm-H2O Met: The pressure readouts are approximate with an accuracy of ±2 cm-H2O for a low pressure range from 0 to 20 cm-H2O. (Device Description section) ±3 cm-H2O for 20 to 40 cm-H2O Met: The pressure readouts are approximate with an accuracy of ±3 cm-H2O for a pressure range of 20 to 40 cm-H2O. (Device Description section) ±5 cm-H2O for pressures above 40 cm-H2O Met: The pressure readouts are approximate with an accuracy of ±5 cm-H2O for pressures above 40 cm-H2O. (Device Description section) Connectivity: Connection to breathing circuit via 22mm male-female adapter Met: Connection to a breathing circuit via a 22 mm male-female adaptor, and accommodates connections through the option of a 22 mm tee or 15 mm port. Also, connected via a "Tee" 15 mm/22 mm ID/OD or "Vertical" plastics connector. (Device Description, Clinical Application sections) Biocompatibility: Met: The device uses materials (Polycarbonate, Acetal, Silicon) for components with indirect patient contact that are the same as predicate devices previously cleared by FDA. (Biocompatibility Testing section) Mechanical Standard Compliance: Met: Compliance with ISO 5356-1 Anaesthetic and respiratory equipment -- Conical connectors - Part 1: Cones and sockets. (Compliance with Performance Standards section) Note: The "acceptance criteria" here are derived directly from the device's specified performance characteristics and design requirements mentioned in the document, as no explicit "acceptance criteria table" for a study was provided. The "reported device performance" are the statements made in the document regarding the device's characteristics.
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- No information provided regarding a test set sample size or data provenance. The document explicitly states "Clinical Studies: None" and "Animal Study: None." The performance data section describes the mechanical operation and accuracy specifications, likely derived from bench testing, not a clinical test set. Data provenance is not mentioned.
-
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. There was no clinical test set for which expert ground truth would be established. The accuracy claims are based on engineering specifications and likely bench testing/calibration.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. No test set requiring expert adjudication was 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:
- Not applicable. This device is a mechanical manometer, not an AI-powered diagnostic or assistive tool. No MRMC study was conducted or mentioned.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a mechanical device, not an algorithm.
-
The type of ground truth used (expert concensus, pathology, outcomes data, etc):
- For the accuracy claims, the ground truth would typically be established by validated calibration standards and highly accurate reference pressure measurement equipment during bench testing. This is not explicitly stated in the document but is implied by the nature of the device (a manometer).
-
The sample size for the training set:
- Not applicable. This device is a mechanical manometer; it does not involve machine learning or a training set.
-
How the ground truth for the training set was established:
- Not applicable. This device is a mechanical manometer; it does not involve machine learning or a training set.
In summary, the provided document pertains to a traditional, mechanical medical device (manometer) undergoing a 510(k) clearance process based on substantial equivalence, primarily supported by bench testing and comparison to predicate devices, rather than a clinical study involving human subjects or an AI/ML algorithm validation study. Therefore, much of the requested information, which is relevant for AI/ML powered devices, is not available or applicable.
