The INOmax DSIR® Plus MRI delivery system is indicated for delivery of INOMAX® (nitric oxide for inhalation) therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant on of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath. The INOmax DSIR® Plus MRI is indicated for use only with MR Conditional ventilators validated to be compatible, as identified in the device labeling.

The INOmax DSIR® Plus MRI is indicated for continuous integrated monitoring of inspired 02, NO2, and NO.

The INOmax DSIR® Plus MRI is considered MR Conditional with the use of 1.5 Tesla static magnetic field scanners ONLY in areas where the field strength is less than 100 gauss.

The target patient population is controlled by the drug labeling for INOMAX® and is currently neonates. The primary targeted clinical setting is a clinical 1.5 Tesla and 3.0 Tesla diagnostic imaging environment.

The INOmax DSIR® uses a "dual-channel" design to provide delivery of INOMAX®. The first channel has the delivery CPU, the flow controller and the injector module to ensure the accurate delivery of NO. The specially designed injector module enables tracking of the ventilator waveforms and the delivery of a synchronized and proportional dose of NO. The second channel is the monitoring system, which includes a separate monitor CPU, the gas cells (NO, NO2, and O2 cells) and the user interface including the display and a comprehensive alarm system. The dual-channel approach to delivery and monitoring permits INOMAX® delivery independent of monitoring but also allows the monitoring system to shut down INOMAX® delivery if the monitored NO concentration exceeds 100 ppm for 12 consecutive seconds. The delivery system can also shut down delivery if it detects certain serious problems with the monitoring system.

The INOmax DSIR Plus MRI incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source.

The INOmax DSIR Plus MRI includes a backup NO delivery capability that provides a fixed flow of 250 mL/min of NO, which along with user supplied 10 L/min of oxygen, provides 20 ppm of NO to a patient breathing circuit. The INOblender® can also be used for backup.

The provided document is a 510(k) summary for the INOmax DSIR® Plus MRI, a nitric oxide administration apparatus. It outlines the device description, intended use, technological characteristics, and a comparison to a predicate device, as well as a summary of nonclinical tests performed.

However, the document does not contain the specific information requested about acceptance criteria and a study proving the device meets those criteria in the context of typical AI/ML medical device submission requirements.

Here's why and what information can be extracted or deduced:

This document describes a hardware medical device, not an AI/ML powered software or diagnostic device. Therefore, the concepts of "acceptance criteria" and "device performance" as typically discussed for AI/ML models (e.g., sensitivity, specificity, AUC) are not directly applicable in the same way. The "performance" here refers to the device's functional operation meeting engineering specifications.

Let's address each point based on the available information:

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

• Acceptance Criteria (Deduced from testing goals): The document implies acceptance criteria are related to the device's functional performance:

  • O2 dilution: The device should not unacceptably dilute oxygen concentration.
  • Effect on delivered pressures: The device should not adversely affect ventilator delivered pressures.
  • INOmax DSIR® delivery accuracy: The device should accurately deliver Nitric Oxide.
  • NO2 generation: The device should not generate unacceptable levels of Nitrogen Dioxide.
  • MRI Compatibility: Device classified as MR Conditional for 1.5 Tesla and 3.0 Tesla static magnetic field scanners in areas where field strength is less than 100 gauss (via ASTM standards and other tests).
  • Electrical Safety & EMC: Conformity to IEC 60601-1 and IEC 60601-1-2.
  • Alarm Systems: Conformity to IEC 60601-1-8.
  • Software Functionality: Software version 3.1.2 meets specified requirements.
  • Usability: Meets human factors engineering requirements (ANSI/AAMI HE75).
  • Backup delivery: Provides fixed flow of 250 mL/min of NO.
