The Quantum Ventilation Module is to only be used by an experienced and trained clinician. The device is not intended to be used by the patient or other untrained personnel.
The Quantum Ventilation Module is an on-line, cardiopulmonary bypass, blood gas monitor that is used for extracorporeal monitoring of blood oxygen (arterial and venous) saturation, hematocrit, and hemoglobin levels. The Quantum Ventilation Module provides gas blending and continuous non-invasive monitoring of critical clinical parameters in extracorporeal circuits used in cardiopulmonary bypass (CPB) or extracorporeal membrane oxygenation (ECMO) procedures. The Quantum Ventilation Module is an accessory to the Quantum Workstation. When paired with the Quantum Workstation, the combination of the Quantum Workstation and Quantum Ventilation Module (QVM2) is known as the Quantum Ventilation System.
The Quantum Ventilation Module performs five functions:
-
- Provides measurements from embedded and attached sensors to monitor gases into and out of a blood oxygenator.
-
- Provides measurements from attached sensors for blood flow, bubble detection, pressure, level, and temperature to monitor an extracorporeal blood loop.
-
- Provides gas blending to ensure the precision delivery of FiO2, CO2 and sweep flow rates.
-
- Provides regulation of vacuum supply to provide two channels of vacuum.
-
- Sends these physiological measurements to the Quantum Workstation for display to the user.
The Quantum Ventilation Module, with its attached sensors, can measure flow, pressure, reservoir level, temperature and gas diagnostics, in addition to performing electronic gas blending of up to three gases and built-in vacuum management for the removal of waste anesthetic gas. The primary interface for controlling and displaying measurements is the Quantum Workstation; however, the Quantum Ventilation Module also contains a touchscreen display with control knobs. The Quantum Ventilation Module only works with the Quantum Workstation.
This FDA 510(k) summary for the Spectrum Medical Quantum Ventilation Module (K202733) indicates that it is a Class II device intended for the continuous monitoring of critical clinical parameters during extracorporeal circulation. The submission claims substantial equivalence to a legally marketed predicate device, Spectrum Medical Ltd.'s Quantum Ventilation Module (K181942).
Here's an analysis of the requested information based on the provided text:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly state acceptance criteria in a quantitative table format for specific performance metrics (e.g., accuracy, precision for flow, pressure, temperature). Instead, it states that the proposed Quantum Ventilation Module (QVM2) has "equivalent sensor performance" to the predicate device.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Functional Equivalence: Provide measurements from embedded and attached sensors to monitor gases, blood flow, bubble detection, pressure, level, and temperature for an extracorporeal blood loop. | The QVM2 performs these functions, including various types of measurements (blood flow, bubble detection, circuit pressure, blood reservoir level, temperature, and gas diagnostics). |
| Gas Blending: Provide gas blending to ensure precision delivery of FiO2, CO2, and sweep flow rates. | The QVM2 performs gas blending of air, oxygen, and carbon dioxide (air/O2/CO2). |
| Vacuum Regulation: Provide regulation of vacuum supply with two channels. | The QVM2 provides regulation of vacuum supply with two channels. |
| Sensor Performance: Equivalent sensor performance to the predicate device. | "equivalent sensor performance" to the predicate (K181942). |
| Electrical Safety: Compliance with relevant standards. | "Electrical safety" testing was performed. |
| Electromagnetic Compatibility (EMC): Compliance with relevant standards. | "Electromagnetic compatibility (EMC)" testing was performed. |
| Hardware Functionality: Proper operation of hardware components. | "Hardware testing" was performed. |
| Software Verification and Validation: Proper functioning and reliability of software. | "Software verification and validation" was performed. |
2. Sample size used for the test set and the data provenance
The document states that "No animal testing was submitted" and "No clinical data were submitted" to support the substantial equivalence. The non-clinical testing mentioned (electrical safety, EMC, hardware, software) refers to engineering verification and validation, not a test set of clinical or animal samples. Therefore, information regarding sample size and data provenance in the context of clinical or animal testing is not applicable here as such studies were not performed.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. Since no clinical or animal testing with a "test set" and "ground truth" established by experts was performed or submitted, this information is not provided. The assessment was based on non-clinical engineering testing and comparison to a predicate device.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable. No test set requiring expert adjudication was used.
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 medical monitoring and control unit, not an AI-assisted diagnostic imaging or interpretation device. Therefore, an MRMC study is not relevant to its type of performance evaluation.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a hardware and software system for continuous monitoring and control during extracorporeal circulation, not a standalone algorithm. Its performance is evaluated through engineering verification and validation of its sensors and control mechanisms.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The concept of "ground truth" derived from expert consensus, pathology, or outcomes data is typically associated with diagnostic or prognostic devices that interpret patient data. For this device, the "ground truth" for its performance evaluation would be based on engineering standards, calibrated reference instruments, and defined physical parameters. For example, when testing flow measurement, the "ground truth" would be established by a known, accurately measured flow rate from a reference system.
8. The sample size for the training set
Not applicable. This device is not an AI/ML device that requires a "training set" in the conventional sense for model development. Its software verification and validation would involve testing against requirements, but not training data for a learning algorithm.
9. How the ground truth for the training set was established
Not applicable, as there is no "training set" for an AI/ML model for this device.

The provided document is a 510(k) Premarket Notification for a medical device called the Quantum Ventilation Module. This type of submission is for demonstrating "substantial equivalence" to a legally marketed predicate device, rather than proving safety and effectiveness through extensive clinical trials as would be required for a Premarket Approval (PMA) application.
Therefore, the document does not describe a study involving an AI algorithm or meeting the typical acceptance criteria for AI/ML device performance. Instead, it focuses on non-clinical performance data to demonstrate the device's functionality and safety as a medical instrument.
Given this context, I will address the questions to the best of what can be inferred from the provided text, noting where the information is absent due to the nature of a 510(k) submission for a non-AI hardware device.
Acceptance Criteria and Device Performance (Based on Non-Clinical Testing for a Hardware Device)
The document primarily discusses non-clinical performance data, which are typically tests to ensure the device performs as intended and is safe. The "acceptance criteria" here are implied by the successful completion of these tests.
1. A table of acceptance criteria and the reported device performance
Since this is a hardware device (Ventilation Module) and not an AI algorithm, the acceptance criteria are not in terms of common AI metrics like sensitivity, specificity, or AUC, nor is there comparative effectiveness data against human readers. The criteria are related to the device's physical and electronic performance, along with its software validation. The document states:
| Acceptance Criteria Category (Implied) | Reported Device Performance Summary (as per document) |
|---|---|
| Electrical Safety | Non-clinical testing performed to support substantial equivalence. (Implies successful completion.) |
| Electromagnetic Compatibility (EMC) | Non-clinical testing performed to support substantial equivalence. (Implies successful completion.) |
| Electrosurgery Interference | Non-clinical testing performed to support substantial equivalence. (Implies successful completion.) |
| Hardware Testing (Printed Circuit Boards) | Non-clinical testing performed to support substantial equivalence. (Implies successful completion.) |
| Software Verification and Validation | Non-clinical testing performed to support substantial equivalence. (Implies successful completion.) |
| Usability Validation | Non-clinical testing performed to support substantial equivalence. (Implies successful completion.) |
| Diagnostic Measurements Accuracy (e.g., flow, pressure, temperature, gas) | "Equivalent sensor performance" to the predicate device (Quantum Diagnostic Module K173591) is claimed, implying accuracy meets established standards for these parameters. |
| Gas Blending Precision (FiO₂, CO₂, sweep flow rates) | Claimed to "ensure the precision delivery" of these parameters. |
| Vacuum Regulation | Provides "regulation of vacuum supply." |
2. Sample size used for the test set and the data provenance
This information is not applicable in the context of an "AI test set" here. The "test set" would refer to the physical units of the device subjected to non-clinical tests. The tests performed ("Electrical safety", "Electromagnetic compatibility", "Electrosurgery interference", "Hardware testing of printed circuit boards", "Software verification and validation", "Usability validation") are typically laboratory-based engineering and software validation tests. The document does not specify the number of units tested, the conditions, or the specific "data provenance" (e.g., country of origin) beyond the manufacturer being in the UK. These are not data-driven performance studies on patient cohorts.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This is not applicable as this is a hardware device. Ground truth, in the context of AI, refers to annotated data. For a hardware device, "ground truth" might refer to established measurement standards or known physical properties used for calibration and validation of sensors. The document does not specify the number or qualifications of experts involved in these engineering validation processes.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods like 2+1 or 3+1 are used for establishing consensus among human readers for image labeling or clinical decision-making ground truth in AI studies. For hardware testing, performance is measured against engineering specifications and industry standards, not through expert adjudication in this manner.
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
No. This is a hardware medical device, not an AI-powered diagnostic or assistive tool. Therefore, an MRMC study is not relevant, and the concept of human readers improving with AI assistance does not apply.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This refers to an AI algorithm's performance. The Quantum Ventilation Module is a hardware device with embedded software, but it's not an AI algorithm that makes diagnostic decisions or interpretations in the way this question implies. Its performance is the measurement and control capabilities of the instrument itself.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. For a hardware device, the "ground truth" for non-clinical performance validation would be derived from:
- Engineering specifications and design documents.
- International and national standards for electrical safety, EMC, and medical device performance (e.g., IEC standards).
- Calibration standards for sensors (e.g., precision gas mixes, flow simulators, temperature baths, pressure gauges).
- Bench testing and physical measurements.
8. The sample size for the training set
Not applicable. This device is not an AI/ML model trained on a dataset. It's a hardware device with firmware.
9. How the ground truth for the training set was established
Not applicable. As there is no "training set" in the AI sense, this question is not relevant. The "ground truth" for developing the device's functionality would stem from engineering principles, clinical requirements for extracorporeal circulation, and established medical device design practices.

The Stöckert Gas Blenders (2L, 5L, and 10L) are intended to enable qualified personnel to set monitor and control gas flows of medical grade gases (air/02/CO2) during cardiopulmonary bypass. The Stockert Gas Blenders are used as components of or optional accessories to the Stöckert S5 System (or any compatible Sorin system using the S5 firmware versions of 3.0 or greater) for periods of six hours or less.
The Stöckert Gas Blender Base Unit is 200 mm wide, 185 mm high, and 270 mm deep and it weighs 2.5 kg. It can be used either from a suitable horizontal surface such as a table or cart or it can be mounted on one of the masts (using the mast holder). It is attached to HLM console with the supplied 24V/CAN connector. This connection provides both power and communication between the Stöckert Gas Blender and the System Display Panel of the HLM. The Stöckert Gas Blenders are designed to provide a maximum mixed gas flow rate of 2L/min, 5L/min or 10 L/min depending on the model used to allow the perfusionist to purge the oxygenator with gas during the priming process. The front panel is the user interface and includes the on/off key, displays and controls. The rear panel houses the three inlet gas connections, the gas mix outlet, and the 24V/CAN connector. Gas line connectors are fast release connectors, consisting of a male connector (installed on the tubing) and a coupler socket (on the housing of the Gas Blender). Both sets (male and female) of connectors are labeled with the respective gas for which they are intended to be used. The Stöckert Gas Blenders enable the qualified perfusionists who are managing the cardiopulmonary bypass circuit using a Stöckert S5 or Sorin C5 System to precisely set, monitor and control the gas flows required for the oxygenation of the patient's blood during extracorporeal circulation. The supply sources for air, O2 and CO2 are connected to the rear inlets of the Stöckert Gas Blender and the gas mixture outlet is connected to the oxygenator (not supplied). The Stöckert Gas Blenders are optional accessories to and designed to be operated with the Stöckert S5 System/Sorin C5 System. They cannot be operated independently from the heart lung machine console. The values for total gas flow (air + O2), FiO2 and CO2 can be adjusted independently without affecting the remaining two values. Gas flow is displayed at both the Stöckert Gas Blender base unit and the remote display module situated in the Stöckert S5 System/Sorin C5 System "control desk" or "System Panel." Set values and actual values are continuously monitored and any discrepancy between them causes both optical and acoustic alarms. If desired, the perfusionist may set alarm limits at the remote display module to monitor the blood flow/gas flow ratio for the arterial pump.
The provided text describes the Stöckert Gas Blender and its FDA 510(k) submission. However, it does not include detailed information about acceptance criteria or a study that specifically proves the device meets those criteria in the format requested.
The document is a 510(k) summary for a medical device (Stöckert Gas Blender). For this type of submission, substantial equivalence to a predicate device is the key, not necessarily a detailed clinical study demonstrating specific performance metrics against pre-defined acceptance criteria in the way a new drug or a novel AI diagnostic might.
Based only on the provided text, here's what can be extracted and what is missing:
1. Table of acceptance criteria and reported device performance:
This information is not provided in the document. The document states that "Design verification and validation testing presented in the 510(k) included electrical/safety testing (IEC60601-1), EMI/EMC testing (IEC60601-1-2), and Functional Acceptance testing, and design validation testing (internal and external)." However, it does not list the specific acceptance criteria for these tests (e.g., accuracy of gas flow, precision of mixture) or the numerical performance results of the device against those criteria.
2. Sample size used for the test set and the data provenance:
This information is not provided. The document mentions general "testing" but no specific test sets or their characteristics.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This information is not applicable/not provided. This device is a gas blender for heart-lung machines, not an AI diagnostic that requires expert interpretation for ground truth. Its performance would be validated through engineering and functional testing.
4. Adjudication method for the test set:
This information is not applicable/not provided. (See point 3).
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
No. The document explicitly states: "No formal clinical testing was provided as the basis for substantial equivalence or is required." Therefore, no MRMC study was conducted or reported here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
This concept is not applicable to this device. The Stöckert Gas Blender is a physical medical device that blends gases, not an algorithm. Its "standalone performance" would be its functional performance, which is generally verified through engineering tests, but specific details are not provided in this summary.
7. The type of ground truth used:
This information is not explicitly stated or applicable in the traditional sense of clinical ground truth (e.g., pathology). For a physical device like a gas blender, "ground truth" would be established by reference standards, calibrated measurement equipment, and compliance with engineering specifications. The document mentions "prospectively defined design and performance specifications," which would form this basis.
8. The sample size for the training set:
This information is not applicable/not provided. As this is a physical device and not an AI/machine learning algorithm, there is no "training set."
9. How the ground truth for the training set was established:
This information is not applicable/not provided (see point 8).
In summary:
The provided document is a 510(k) summary for a medical device focused on demonstrating substantial equivalence to a predicate device. It confirms that engineering, safety, and functional testing were performed but does not delve into the specific acceptance criteria or the detailed results of those tests, nor does it involve clinical studies or AI-related performance metrics.

The intended use of the Sechrist Model 3500CP-G Air/Oxygen Mixer is to enable qualified personnel to mix medical grade air and medical grade oxygen at operator selected ratios, for delivery to patients through various types of respiratory care and heart bypass oxygenation equipment.
The Sechrist Model Series 3500CP-G Air/Oxygen Mixer is a precision pressure regulation and proportioning device which is intended to mix medical grade air and medical grade oxygen. The mixer receives pressurized air and oxygen, at a nominal 50 psi, via Diameter Index Safety System (D.I.S.S.) inlet connections. The unit will operate satisfactorily with inlet pressures of 30 to 70 psi, providing the pressures are within 20 psi of one another. Two outlets for the mixed gas are provided. The air/oxygen mixers are configured with zero to three flowmeters. Accessories include air and oxygen hoses.
The provided 510(k) summary for the Sechrist 3500CP-G Air/Oxygen Mixer does not contain information about a study conducted to prove the device meets specific acceptance criteria based on numerical performance metrics. Instead, the submission focuses on demonstrating substantial equivalence to previously cleared predicate devices through adherence to established quality system standards and verification of the device's intended function.
Therefore, many of the requested details about acceptance criteria, device performance, sample sizes, ground truth establishment, expert adjudication, and MRMC studies are not applicable to this type of submission.
Here's a breakdown of the available information and how it relates to your request:
Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Function as a precision pressure regulation and proportioning device to mix medical grade air and oxygen. | The device receives pressurized air and oxygen at nominal 50 psi via D.I.S.S. inlet connections. It operates satisfactorily with inlet pressures of 30 to 70 psi, provided pressures are within 20 psi of one another. It provides two outlets for mixed gas and is configured with zero to three flowmeters. (This describes the design and operational parameters, implying it meets the functional requirements of a gas mixer). |
| Mix medical grade air and medical grade oxygen at operator-selected ratios. | Description confirms this as the primary function ("intended to mix medical grade air and medical grade oxygen at operator selected ratios"). |
| Delivery of mixed gases to patients through various types of respiratory care and heart bypass oxygenation equipment. | Indications for Use explicitly state this as the purpose of the device. The 510(k) summary also explicitly extended the indications to include cardiopulmonary bypass purposes, aligning with predicate devices. |
| Adherence to relevant quality system standards. | The device is designed and manufactured in accordance with ISO 9001, ISO 13485, EN 46001, and 21 CFR 820 Quality System Regulation. |
| Substantial equivalence to predicate devices for its intended use. | The primary conclusion of the 510(k) is that "The device is substantially equivalent to the devices previously cleared under the above referenced 510(k) numbers." This is the overarching "acceptance criteria" for a 510(k) clearance. |
Study Information (Based on the provided text):
-
Sample size used for the test set and the data provenance:
- Not applicable/Not provided. This 510(k) relies on demonstrating substantial equivalence to predicate devices and adherence to design/manufacturing standards, rather than a clinical performance study with a test set of data.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable/Not provided. No specific "test set" with "ground truth" derived from experts is mentioned for this type of submission.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable/Not provided.
-
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 is a submission for a hardware device (gas mixer), not an AI/software device that would involve human readers or AI assistance.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a hardware device.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Not applicable/Not provided in the context of a performance study. The "ground truth" for this device's performance would be its ability to physically mix gases within specified tolerances, which would be verified through engineering testing and quality control during manufacturing, not typically a "ground truth" established by experts in a clinical study sense for a 510(k) submission like this.
-
The sample size for the training set:
- Not applicable/Not provided. Training sets are relevant for machine learning algorithms, which is not the case here.
-
How the ground truth for the training set was established:
- Not applicable/Not provided.
Summary of the 510(k) Approach:
The 510(k) for the Sechrist 3500CP-G Air/Oxygen Mixer demonstrates its acceptability through:
- Substantial Equivalence: Comparing the device's design, indications for use, and technological characteristics to legally marketed predicate devices (K802226, K992503, K841789, K863902, K901253). The key "study" here is the comparative analysis showing that the new device is functionally the same or very similar to existing cleared devices.
- Adherence to Standards: Compliance with established national and international quality management system standards (ISO 9001, ISO 13485, EN 46001, 21 CFR 820). This implies that the design, manufacturing, and performance verification processes are robust, reducing the need for a separate detailed clinical performance study in this context.
- Device Description: A detailed description of the device's function and operational parameters, which are presumed to be consistent with those of the predicate devices.
This type of submission typically relies on design verification and validation testing performed by the manufacturer, which demonstrates the device meets its own specifications, rather than a clinical study establishing performance against a "ground truth" in a patient population. These internal tests would verify parameters like pressure regulation accuracy, mixing ratio accuracy, and flow characteristics, but the 510(k) summary itself does not detail the results of these internal tests.

The Coeur Front Load Injector Retrofit Kit is intended to be used with Medrad MCT and MCT Plus Injectors to hold the Coeur 200 mL Front Load Syringe in place in front of the Iniector Ram during the injection of contrast media into the vascular system for diagnostic purposes.
The Coeur Front Load Retrofit Kit consists of two accessory pieces for use with Medrad MCT and MCT Plus Injector Systems and older models of Medrad injectors upgraded by Medrad to resemble the MCT and MCT Plus. The kit contains a face plate and ram tip extension that allow easy use of the Coeur 200 mL Front Load Syringe on the modified versions of Medrad injectors. This premarket notification describes the Coeur Face Plate Retrofit Kit, which is a modification of the Coeur Front Load Injector Turret, which allows use of the Coeur 200 mL Front Load Syringe on older models of Medrad injectors.
The Face Plate uses a standard bayonet mount to attach directly onto the Medrad injectorbase on the MCT and MCT Plus injectors. The ram tip extension is then attached to the existing ram tip and tightened into place to prevent slippage. Once in place, the Coeur 200 mL Front Load Syringe may be used easily on the injectors.
This is a submission for a medical device (injector retrofit kit), not an AI/ML device. Therefore, many of the requested categories (e.g., ground truth, training set, multi-reader multi-case studies) are not applicable.
Here's the information derived from the provided text, focusing on what is relevant for a hardware modification:
Acceptance Criteria and Device Performance for Coeur Front Load Injector Retrofit Kit
