Temperature reduction for adult patients where clinically indicated, e.g. in hyperthermic patients.

The IQool™ System is a surface cooling device that sustains and monitors patient temperature within a range of 33°C to 37°C. The IQool™ System consists of: ECU 100 – refrigeration and control unit – The ECU 100 is a refrigerator unit with an integrated control system operated via a touch screen monitor. BC COOL- BC COOL is a cooling liquid consisting of diluted monopropylene glycol (MPG5). The dilution is made by BrainCool AB to optimally serve the IQool™ System. Five liters of BC COOL are delivered with the system. Cooling Pads – the single use cooling pads are the only skin contacting component and can be fitted to the head/neck, torso, and thigh. Liquid coolant is circulated from the tank through the pads to cool patients. The cooling pads are designed and molded to give a good fit during treatment and are intended for single patient use. Stabilization insulation – The patented stabilization insulation is made of insulating and moisture-absorbent neoprene. The stabilization insulation supports the cooling pads and insulates against the ambient environment condensation. The elasticity of the stabilization insulation keeps the Cooling Pads in place during treatment and ensures maximum cooling between the skin and the surface of the Cooling Pad. The stabilizing insulation is intended for single use only. Accessories: BC STICK — The BC STICK is a USB flash drive used to save system configurations, specifically prepared to communicate with the program of the IQool™ System. The BC stick does not store or capture any user identifying information. It can also be used to save a log file for system troubleshooting or to update the software. Filling pitcher – The filling pitcher is for refilling the tank with BC COOL (coolant). Fill the tank with coolant before or directly after start to avoid damage to the system. The ECU 100 pushes temperature-controlled BC COOL ranging between 4°C and 30°C through the Cooling Pads at approximately 1.2 liter per minute per pad. This results in heat exchange between the BC COOL and the patient. Patient temperature is monitored by one or two commercially available third-party temperature probes. The IQool™ System maintains a controlled patient temperature during the entire treatment period. Any deviations from the default temperature are automatically adjusted by the system. The default treatment settings for temperature and time can be changed through the touchscreen monitor. Alarms and notifications are activated if any errors are detected. Temperature graphs for each treatment are shown on the touchscreen display for visual monitoring.

The provided text describes a medical device, "The IQool System," and its claim of substantial equivalence to a predicate device. However, it does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria in the format typically used for AI/ML device evaluations (e.g., sensitivity, specificity, AUC).

Instead, the document focuses on regulatory submission (510(k)) for a thermal regulating system and its comparison to a predicate device. The performance data section broadly states that "Testing was completed for the IQool™ System which demonstrated intended, labeled device performance," and lists various functional, temperature, software, and safety tests, as well as adherence to standards.

Therefore, I cannot populate the table or answer most of your specific questions based on the provided text, as this document type typically doesn't contain that level of detail for performance metrics, study design, or ground truth establishment relevant to AI/ML device evaluations.

Here's what can be inferred or stated about the device based on the provided text, recognizing its limitations regarding your specific questions:

Device: The IQool System (Thermal Regulating System)

Intended Use: Temperature reduction for adult patients where clinically indicated, e.g., in hyperthermic patients.

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

Note: The document broadly states "All testing confirmed that the IQool™ System operates as described and is substantially equivalent to the predicate device" in lieu of specific numerical performance outcomes for many criteria.

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

This information is not provided in the document. The document describes general performance testing and standards compliance, not a clinical trial or specific test set with patient data.

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)

This information is not provided in the document. The device is a thermal regulating system, not an AI diagnostic tool requiring expert ground truth for interpretation of outputs like images.

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

This information is not provided in the document. Not applicable for this type of device and testing described.

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

This information is not provided in the document. This is not an AI/ML diagnostic device with human reader interaction.

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

The device is a physical thermal regulating system. Its "performance" is based on its ability to control temperature as per its design. The document states it was functionally tested and meets standards, implying a standalone performance assessment of the device's physical and software functions. The "algorithm" in this context refers to its internal control system for temperature regulation, not an AI for interpretation.

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

For a thermal regulating system, "ground truth" would typically refer to:

• Reference temperature measurements: Calibrated temperature probes would act as the ground truth for measuring the patient's core temperature.
• System set points: The desired temperature set by the clinician would be the target "ground truth" for the device to achieve and maintain.
• Engineering specifications: Conformance to design specifications for cooling rates, fluid parameters, and safety elements.

The document states "Patient temperature is monitored by one or two commercially available third-party temperature probes." These probes would serve as the reference for patient temperature.

8. The sample size for the training set

This information is not provided in the document. This concept (training set) is typically relevant to AI/ML models, not purely electro-mechanical medical devices with control system software.

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

This information is not provided in the document. Not applicable given the type of device.
