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 (VDS) controls pharmaceutical-grade NO/N2 delivery into inspiratory limb of patient breathing circuit; maintains steady NO concentration via continuous inspiratory flow measurement and rapid injection adjustment. Device comprises cart, gas manifold, control panel, NO delivery module, and main electronics unit. Used in clinical settings by healthcare providers; provides real-time gas monitoring (NO, NO2, O2) via side-stream sampling and electrochemical cells. Output displayed on backlit LCD; assists clinicians in managing nitric oxide therapy. Benefits include precise, automated gas delivery and monitoring to support respiratory therapy. ## 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 2000). ## Technological Characteristics Cart-mounted nitric oxide delivery and monitoring system.

Canada TOB 4J0 Telephone: 780-451-3660 Fax: 780-526-4200 Device Name: ViaNOx Delivery System™ (VDS) Common Names: Nitric Oxide Delivery Apparatus, Nitric Oxide Analyzer and Nitrogen Dioxide Analyzer Predicate Device: INOvent® Delivery System ### Device Description: The ViaNOx Delivery System controls the delivery of pharmaceutical arade NO/N2 into the breathing gas stream passina down the inspiratory limb of a patient circuit, The injected flow of NO/N₂ is controlled to maintain a steady concentration of NO/N₂ within the inspiratory limb at all times, both during and between breaths. Constant concentration operation is accomplished by confinuously measuring the flow in the inspiratory limb and adjusting the injected NO/Nz 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 manifold 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.

system | The INOvent Delivery System provides for nitric
oxide delivery using a manual delivery system
as outlined in their operating instructions on
pages 8-1 to 8-3. The system works by
connecting an oxygen source to the INOvent
O2 inlet and then connecting a user supplied
self-inflating bagger to the INOvent NO/O2
outlet. The "NO/O2 outlet" delivers NO from the
INOvent combined with oxygen (user supplied
to the "O2 inlet"). | The ViaNOx Delivery
System provides for
manual ventilation in
much the same
manner except that
the circuitry is external
to and located on the
front of the device. The
INOvent has a flow
meter on their device.
The VDS utilizes the user
supplied flow meter. | | | The INOvent also provides for manual
resuscitation as described on pages 6-13 to 6-
15 of the operating manual. In these
applications, the Injector Module is used to
control the NO concentration to the manual
resuscitator using various configurations. | The ViaNOx Delivery
