The SERVO i Ventilator System is intended for treatment and monitoring of patients in the range of neonates, infants, and adults with respiratory failure or respiratory insufficiency. SERVO-i is a ventilator system to be used only by healtheare providers in hospitals or healthcare facilities and for in-hospital transport.

The added indications for use of the NAVA option is when the electrical signal from the diaphragm is intact; NA VA will improve synchrony between the ventilator and patients with no contraindication for insertion/exchange of a Naso-Gastric tube.

The SERVO-i Ventilator is classified as MR Conditional for 1.T. 1.5T and 3T MR scanners. This means that it is safe to use in the MR environment if the MR Environment Declaration for SERVO-i are met.

The SERVO-i Ventilator System with Heliox option is indicated for use with the delivery of Air, Oxygen, or Heliox (a mixture of Helium and Oxygen).

The SERVO-s Ventilator System is intended for treatment and monitoring of patients in the range of neonates, infants, and adults with respiratory failure or respiratory insufficiency. SERVO-s is a ventilator system to be used only by healthcare providers in hospitals or healthcare facilities and for in-hospital transport.

The SERVO-i Ventilator System (here after called SERVO-i) is intended to provide continuous ventilation for neonate to adult patients in the weight range 0.5-250 kg and with tidal volumes from 2 mL to 4000 mL. SERVO-i consists of a Patient Unit where gases are mixed and administered, and a User Interface where the settings are made and ventilation is monitored. The ventilator delivers controlled or supported breaths to the patient, with either constant flow or constant pressure, using a set oxygen concentration. SERVO-i will produce visual and audible alarms if vital parameters vary beyond pre-set, or default, limits. The system contains provisions for at least two battery modules to supply the system in the case of mains power failure or during in-hospital transport. The ventilator functionality is controlled by software. The SERVO-i Ventilator System is available in three software versions. Infant. Adult and Universal.

The NAVA (Neurally Adjusted Ventilatory Assist) option is a supported mode for SERVO-i that uses the Edi signal (the electrical activity of the diaphragm) as an addition to the flow/pressure trigger to synchronize the patient efforts with the onset and cycle off. The NAVA option is available in invasive and non-invasive mode.

SERVO-i is MR conditional. The SERVO-i ventilator with MR option have been tested with 1.0, 1.5, 3.0 T scanners without impairing its performance or the image quality of the scanner. Each scanner and its environment form an individual device. The MR Environment Declaration describes how a SERVO-i with MR option can be qualified to be used with an MR scanner forming a safe Medical System. All vital parts of the ventilator have been tested for performance in excessive magnetic fields.

The SERVO-i with Heliox option requires a different mechanical adaptor on the air supply inlet to allow a mixture of Helium and Oxygen to be connected. Furthermore is the software updated to allow safe delivery and monitoring of the Heliox gas mixture.

Accessories for CO2-monitoring, nebulization and flow monitoring at the Y -piece (Y-sensor) are integrated as options in the SERVO-i and the drivers are controlled by the software in the ventilator.

The HAMILTON-G5's pneumatics deliver gas, and its electrical systems control pneumatics, monitor alarms, and distribute power.

The user interface consists of a LCD-display with touch screen, keys, and a press-andturn knob.

The HAMILTON-G5 provides audible and visual patient- and ventilator-related alarms.

The provided 510(k) summary for the HAMILTON-G5 ventilator focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study with specific acceptance criteria and performance metrics in the format usually associated with AI/ML device evaluations.

Here's a breakdown of the available information based on your request, along with explanations for missing sections:

1. Table of Acceptance Criteria and Reported Device Performance

The submission does not specify numerical acceptance criteria or present performance data in a quantitative table. The evaluation relies on demonstrating that the HAMILTON-G5 ventilator "conforms to the FDA recognized standards for safety and performance issues with lung ventilators" and that "the test results indicated that the device performed as specified." This implies that the device met pre-established engineering and regulatory standards, but these are not explicitly listed as "acceptance criteria" with corresponding "reported device performance" values in the document.

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

This information is not provided in the document. The submission states "Performance tests were performed," but does not detail the nature of these tests, the number of devices or scenarios tested, or the origin of any data (e.g., country of origin, retrospective/prospective). This is typical for a traditional medical device submission where the focus is on engineering and safety standards rather than clinical data sets.

3. Number of Experts Used to Establish Ground Truth and Qualifications

This information is not applicable/not provided. The HAMILTON-G5 is a continuous ventilator, not an AI/ML diagnostic or predictive device that would require expert-established ground truth for its performance evaluation in the context of this 510(k) summary. Its performance would be assessed against technical specifications and safety standards for ventilation.

4. Adjudication Method for the Test Set

This information is not applicable/not provided. As explained above, the device's performance is not evaluated based on expert adjudication of "ground truth" data in this context.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

This information is not applicable/not provided. The HAMILTON-G5 is a standalone medical device, not an AI-assisted diagnostic or decision support tool for human readers. Therefore, an MRMC study comparing human readers with and without AI assistance is not relevant to this submission.

6. Standalone (Algorithm Only) Performance Study

This information is not applicable/not provided. The HAMILTON-G5 is a physical ventilator, not an algorithm. Its performance is inherent to its mechanical and electronic design and operation, not a software algorithm that can be evaluated in isolation.

7. Type of Ground Truth Used

This information is not applicable/not provided. The concept of "ground truth" (e.g., pathology, outcomes data) usually applies to diagnostic or predictive devices being evaluated against a definitive standard. For a ventilator, performance is typically assessed against engineering specifications, safety standards, and physiological parameters (e.g., delivered tidal volume accuracy, pressure control, alarm thresholds) that are measurable and verifiable.

8. Sample Size for the Training Set

This information is not applicable/not provided. The HAMILTON-G5 is a hardware medical device with embedded software, not a machine learning model that undergoes a "training" phase with a dataset in the conventional sense. Its development involves engineering design, testing, and validation according to established medical device development processes.

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

This information is not applicable/not provided for the same reasons as #8.

In summary:

The provided 510(k) summary for the HAMILTON-G5 ventilator demonstrates substantial equivalence to predicate devices based on technological characteristics and performance specifications. It states that "performance tests were performed, and the test results indicated that the device performed as specified," and that the device "conforms to the FDA recognized standards for safety and performance issues with lung ventilators." However, it does not contain the detailed, quantitative acceptance criteria, study methodologies, or data provenance typically found in submissions for AI/ML-driven devices. The nature of the device (a continuous ventilator) means many of the requested categories (e.g., expert-established ground truth, MRMC studies, training sets) are not relevant to its 510(k) clearance process.
