Device Name: Device Trade Name: AeroNOx Nitric Oxide Titration & Monitoring System Common/Classification Name: AeroNOx Nitric Oxide Delivery Device - 2. Address and Registration Number: International Biomedical, Ltd. 8508 Cross Park Drive Austin, TX 78754 FDA Registration #: 1625392 DEC 1 6 2009 - 3. Device Class: Nitric Oxide Delivery Apparatus are classified as Class II, Product Code MRN, Anesthesiology. - 4. Predicate Device Information: The predicate device is the AeroNOx Nitric Oxide Titration & Monitoring System, K000653, 8/4/00. - 5. Labeling: The product labeling has been changed to add three additional ventilators to the list of validated ventilators in the user manual. No other labeling changes have been made. A copy of the revised manual is included in the submission. - 6. Intended Use: The AeroNOx is intended to provide a constant controlled concentration of nitric oxide in breathing gas by delivering a constant controlled flow of nitric oxide into the inspiratory limb of a mechanical ventilator that operates using a continuous constant flow of fresh gas into the inspiratory limb of the ventilator. The AeroNOx is also intended to be used with a flow inflating manual ventilator (an AeroNOx accessory), by introducing controlled flows of nitric oxide into the fresh gas flow to the manual ventilator. It is also intended to monitor nitric oxide, nitrogen dioxide, and oxygen concentrations in the breathing gas. The AeroNOx is intended to be used within a hospital or during air or ground transport outside the hospital. The intended use of the AeroNOx has not changed. The indications for use statement can be found in attachment 2. {1}------------------------------------------------ # Special 510(k): Device Modification AeroNOx Nitric Oxide Titration & Monitoring System October 13. 2009 ## SECTION 2: DEVICE SUMMARY ## 7. Device Description and Comparison: The AeroNOx nitric oxide delivery system is specifically designed for the transmission . and control of gaseous nitric oxide (NO) in parts per million (ppm) concentrations. It is divided into two main components: the titration delivery system and the NO/NO2/O2 . analyzer. These two components are mounted into a single enclosure. The construction materials are compatible with NO and will not contaminate the gas stream. A stainless steel, two stage regulator with CGA 626 gas fittings is coupled to a calibrated, high accuracy NO mass flow meter and precision metering valve. The NO is titrated continuously via tubing nearest to the ventilator outlet circuit where it is diluted by the ventilator gas flow. Initial NO flow required to approximate a desired NO concentration is estimated by calculation and verified by the monitoring component of the system. We have also included a look-up table for specific ventilator settings, AeroNOx NO flow setting and expected NO2 production based on 100% Oxygen source, in the operating manual. The AeroNOx analyzer continuously draws a sample from the ventilator circuit on the distal point of the inspiratory circuit nearest the patient wye connection. The sensors then measure NO and NO2 concentration in parts per million and Oxygen in %. The sensors operate by electrochemical means. NO, O2 and NO2 molecules diffuse across a membrane and react in the electrolyte solution augmenting an electrical current between the anode and cathode. The augmented current is proportional to the NO, O2 and NO2 concentration. The AeroNOx analyzer has been designed so that the user can set alarm limits to ensure that deviations in NO and NO2 can be monitored. These alarms are visual and audible. An oxygen analyzer is also incorporated into the system to act as a secondary monitor to display the fractional inspired oxygen concentration. ## - No device modifications have been made from the predicate device. The only modification made is to the list of ventilators that may connect to the AeroNOx in the Operator's Manual (page 22). #### 8. Substantial Equivalence: The modified AeroNOx has the following similarities to the previous AeroNOx model that already has 510(k) clearance: - . The same intended use - . Use the same operating principle - Incorporate the design and electronic circuitry - . Incorporate the same materials . In summary, the AeroNOx Nitric Oxide Titration & Monitoring System described in this submission is, in our opinion, substantially equivalent to the predicate device. ਨ {2}------------------------------------------------ ### Special 510(k): Device Modification AeroNOx Nitric Oxide Titration & Monitoring System October 13, 2009 #### INDICATIONS FOR USE STATEMENT #### Applicant's Name: International Biomedical, Ltd. **510(k) Number:** K093260 #### Device Name: AeroNOx Nitric Oxide Titration & Monitoring System #### Indications for Use: The AeroNOx is intended to provide a constant controlled concentration of nitric oxide in breathing gas by delivering a constant controlled flow of nitric oxide into the inspiratory limb of a mechanical ventilator that operates using a continuous constant flow of fresh gas into the inspiratory limb of the ventilator.
