Intended Use

The ViaNOx Delivery System is a nitric oxide administration device intended to add nitric oxide to gases that are to be breathed by a patient, and to be used in conjunction with a ventilator or other breathing system. The ViaNOx includes a nitric oxide, nitrogen dioxide, and oxygen monitor intended to monitor the concentration of these gases in respiratory gas mixtures during administration of nitric oxide.

Device Story

ViaNOx Delivery System (Model II) administers pharmaceutical-grade NO/N2 into patient breathing circuits. Device continuously measures inspiratory limb flow to adjust injected NO/N2 flow rate, maintaining constant gas concentration during and between breaths. System includes cart, gas plumbing, manual delivery component for resuscitators, control panel, and NO delivery module. Used in clinical settings by healthcare providers to manage nitric oxide therapy. Output provides real-time monitoring of NO, NO2, and O2 levels. Modifications include single-cylinder plumbing, configurable cart caddy for small cylinders, and oxygen supply alarm for manual delivery. Device supports clinical decision-making by ensuring precise, steady-state delivery of nitric oxide to patients on respiratory support.

Clinical Evidence

Bench testing only. Testing performed in accordance with FDA Guidance Document for Premarket Notification Submissions for Nitric Oxide Delivery Apparatus, Nitric Oxide Analyzer and Nitrogen Dioxide Analyzer (Jan 24, 2000).

Technological Characteristics

Nitric oxide administration apparatus; includes NO, NO2, and O2 monitoring. Features single or dual cylinder gas supply plumbing, configurable cart (caddy system), and manual delivery system with oxygen supply alarm. Compatible with various ventilators including Bio-Med Devices MVP 10. Class II device.

Indications for Use

Indicated for patients requiring nitric oxide administration via a ventilator or breathing system. Monitors NO, NO2, and O2 concentrations in respiratory gas mixtures.

Regulatory Classification

Identification

The nitric oxide administration apparatus is a device used to add nitric oxide to gases that are to be breathed by a patient. The nitric oxide administration apparatus is to be used in conjunction with a ventilator or other breathing gas administration system.

Device Name: ViaNOx Delivery System™ (ViaNOx-ds™)

Common Names: Nifric Oxide Delivery Apparatus, Nitric Oxide Analyzer and Nitrogen Dioxide Analyzer

Predicate Device: ViaNOx Delivery System™

#### Device Description:

The ViaNOx Delivery System controls the delivery of pharmaceutical grade NO/N2 into the breathing gas stream passing down the inspiratory limb of a patient circuit. The injected flow of NO/Nz is controlled to maintain a steady concentration of NO/Nz within the inspiratory limb at all times, both during and between breaths. Constant concentration operation is accomplished by continuously measuring the flow in the inspiratory limb and adjusting the injected NO/N2 flow rate accordingly. The measure and adjust process is very rapid, and thus provides essentially immediate tracking of changes in the inspiratory flow rate and pattern.

The device consists of a cart, a gas plumbing connecting the gas supply to the device, a manual NO delivery system for use with a user supplied manual resuscitator and oxygen supply. a control panel, an NO Delivery Module and the main unit which houses the electronics and most of the software and to which all other components connect.

#### Intended Use:

"The ViaNOx Delivery System is a nitric oxide administration device intended to add nitric oxide to gases that are to be breathed by a patient, and to be used in conjunction with a ventilator or other breathing system. The ViaNOx includes a nitric oxide, nitrogen dioxide, and oxygen monitor intended to monitor the concentration of these gases in respiratory gas mixtures during administration of nitric oxide."
