The device is intended to provide continuous or intermittent mechanical ventilator support for the care of individuals who require mechanical ventilation. Specifically, the NEWPORT HT50 is applicable for adult and pediatric (i.e. infant, child and adolescent) patients, greater than or equal to 10 kg (22 lbs), who require the following general types of ventilatory support: positive pressure ventilation with Assist/Control, SIMV and SPONT/CPAP modes of ventilation.

The NEWPORT HT50 is a restricted medical device intended for use by qualified, trained personnel under the direction of a physician; it is suitable for use in hospital, sub-acute, emergency room, and home care environments, as well as for transport and emergency response applications.

Device Description

The modified NEWPORT HT50 Ventilator is an electrically powered, microprocessor controlled, variable flow generating ventilator which provides Assist Control, SIMV and SPONT/CPAP modes of ventilation in combination with servo-solenoidcontrolled, built-in PEEP.

The modified NEWPORT HT50 may be powered by external power (100-240 VAC or 12-30 VDC) or internal battery system power. Any time external power is connected to the ventilator, the internal battery system is charging.

2. Sample Size Used for the Test Set and Data Provenance

The document does not specify a distinct "test set" in the context of patient data or clinical trials. Instead, the testing described appears to be primarily engineering verification and validation of the device itself and its new battery system.

Sample Size: Not applicable in the traditional sense of patient data. The "sample" would be the device itself (presumably one or more units).
Data Provenance: The testing was integral to the device development and modification, suggesting it was conducted prospectively by the manufacturer (Newport Medical Instruments, Inc.). There is no mention of country of origin for external data as no such data was used.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This section is not applicable as the described testing did not involve establishing ground truth from patient data with expert review. The "ground truth" here would be the defined engineering specifications and regulatory standards that the device performance was measured against. The experts involved would be the engineers and quality assurance personnel at Newport Medical Instruments responsible for designing, testing, and verifying the device's compliance. Their qualifications are not explicitly stated in the submission but would include expertise in ventilator design, electrical engineering, software engineering, and regulatory compliance.

4. Adjudication Method for the Test Set

This is not applicable as there was no expert review or consensus-based ground truth establishment using patient data. The "adjudication" in this context would be the internal review and approval processes by the manufacturer's engineering and quality teams to confirm that the test results met the predefined specifications and standards.

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, an MRMC comparative effectiveness study was not done. This submission is for a continuous ventilator, not an AI-assisted diagnostic or interpretative device that would typically involve human readers.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This is not applicable as the device is a mechanical ventilator, not an algorithm, and its operation inherently involves a human operator (qualified, trained personnel under the direction of a physician). The performance testing was for the device's physical and functional capabilities, not an algorithm's standalone accuracy.

7. The Type of Ground Truth Used

The ground truth used for this submission is based on:

Engineering Specifications: Designed performance parameters for the ventilator and its DUAL PAC™ Internal Battery system (e.g., specific voltage switching points, charging circuit functionality, alarm thresholds, and minimum battery run times).
Regulatory Standards: Compliance with relevant national and international standards for medical devices, electrical safety, environmental testing, and EMC (e.g., MIL-STD-810E, IEC 68-2).
Predicate Device Performance: The modified device's performance was also assessed against the established safety and effectiveness of its predicate devices.

8. The Sample Size for the Training Set

This is not applicable. The device is a mechanical ventilator, not a machine learning algorithm that requires a "training set" of data.

9. How the Ground Truth for the Training Set Was Established

This is not applicable for the same reason as above; there is no training set mentioned or implied for a mechanical ventilator.

IV. Device Description

{1}------------------------------------------------

V. Intended Use

This modified NEWPORT HT50 is intended to provide continuous or intermittent mechanical ventilator support for the care of individuals who require mechanical ventilation. Specifically, the NEWPORT HT50 is applicable for adult and pediatric (i.e. infant, child and adolescent) patients, greater than or equal to 10 kg (22 lbs), who require the following general types of ventilatory support: positive pressure ventilation with Assist/Control, SIMV and SPONT/CPAP modes of ventilation.

The modified NEWPORT HT50 is a restricted medical device intended for use by qualified, trained personnel under the direction of a physician; it is suitable for use in hospital, sub-acute, emergency room, and home care environments, as well as for transport and emergency response applications.

Technological Characteristics VI.

The modified NEWPORT HT50 combines a secondary, internal, back-up Nickel-Metal Hydride (NiMH) battery with an independent charging system with the existing Lead Acid (LA) internal battery and charging system, thereby creating the DUAL PAC™ Internal Battery system. When the primary internal LA battery charge level reaches the low battery threshold, the Low Battery alarm activates (message, LED indicator and audible alarm). The unit will automatically add in the power of the secondary NiMH battery and both batteries will continue to power the ventilator and the alarms for a minimum of 30 minutes before shut down. This alarm message (Low Battery), the blinking LED indicator and audible alarm give notice that a minimum of 30 minutes remains to find an alternate power source before the unit will shutdown. When the combined battery power reaches the battery empty threshold, a Battery Empty alarm is activated (message, LED indicator and audible alarm) alerting the user that there is a minimum of 15 minutes to shut down. Ensuring these defined time periods for battery life increases the margin of safety for battery usage.

VII. Device Testing

Testing supporting transport use of the device was based on the following standards:

MIL-STD-810E Environmental Test Methods and Engineering Guidelines .
IEC 68-2 Environmental Testing .

Testing for the DUAL PAC Internal Battery design encompassed validation and verification of the new design, re-verification of all functional and alarm aspects, and EMC and safety testing; this testing is summarized following:

A. Validation and Verification of New Design
The battery pack and charging circuits were tested to verify functionality, including:
Correct switching to back-up battery at target voltage; .
Proper charging circuit function; .
Ventilator operation on main battery and back up battery; .

{2}------------------------------------------------

Verification of proper warnings; .
Verification of proper switching to back up battery if main battery is defective; and
Verification of proper warning to user in the event that back up battery . is defective.

Re-Verification of All Functions and Alarms B.

The NEWPORT HT50 was tested to ensure proper functionality and alarming for ventilator operations. This complete re-verification of all functions/alarms assured that software revisions associated with the DUAL PAC Internal Battery system did not inadvertently affect any ventilator function or alarm.

C. EMC and Safety Testing

Testing was also performed to assure that the ventilator with the new battery pack configuration meets electrical safety, environmental, and EMC requirements.

Clinical and Animal Testing VIII.

No clinical or animal data were included in this submission.

IX. Conclusions

All testing demonstrates that the modified NEWPORT HT50 Ventilator performs as intended and is therefore suitable for its intended use.
