Display and user controls The INOmax DSIR has a color touch screen display and a control wheel for adjusting and/or confirming user settings. The buttons on the touch screen and the control wheel perform a variety of functions using a three-step procedure (see “Setting and making changes on the INOmax DSIR”). Note: • If a button has been selected and no activity has been sensed within 20 seconds, the display will return to its previous screen. If a button is de-emphasized (grayed out), it is not accessible. • Position delivery system so user screen is unobstructed and the speaker is not covered.

When a value is being changed, pressing the "Cancel Active Status" button during editing will stop the change and return the parameter to its original value (similar to the escape key on a computer).

Dose settings The range of NO dose settings for the INOmax DSIR is configured by the distributor for a specific INOMAX (nitric oxide) concentration, e.g., 400 ppm or 800 ppm. If configured for 400 ppm the range of NO dose setting is 0 to 40 ppm and if configured for 800 ppm the range is 0 to 80 ppm, see below. 400 ppm

800 ppm

Each click on the control knob corresponds to a known change in dose. The incremental dose per click corresponds to a value dependent upon the dose range in which the change is made, as illustrated in the table below. Dose Setting Range < 1 ppm 1 to 40 ppm 40 to 80 ppm

Infrared Communication between the INOMAX Cylinders and the INOmax DSIR The INOmax DSIR has an interface using infrared (IR) technology which allows the INOmax DSIR to communicate with the INOmeter (which is mounted to each INOMAX cylinder). The INOmax DSIR checks the INOMAX cylinder for the correct expiration date and cylinder concentration. The INOmax DSIR also transmits a confirmed patient identifier to the INOmeter on any open INOMAX cylinder. The INOmax DSIR cart has a cover ( 1 ) with an infrared transceiver mounted directly above each INOMAX cylinder. When INOMAX cylinders are loaded, communication will take place between the INOmax DSIR and the INOmeter ( 2 ) after the boot up phase of the INOmax DSIR is complete. A cylinder icon will be displayed on the main screen when an INOMAX cylinder is recognized by the INOmax DSIR (see “Loading INOMAX Cylinders onto the INOmax DSIR Cart”, page 13).

IR Communication Interference The INOmax DSIR transceiver is located under the cart cover and should be protected from outside IR sources. The INOmax DSIR cart was designed to protect the INOmeter from external light/IR energy sources. The INOmax DSIR transceiver transmits via a 30 degree transmission cone projecting towards the floor (see dotted lines in Figure 1-6). The specifications of the IR beam call for it to have a range of 20 cm (7.9 in). Based on these specifications it would not affect other devices in the vicinity of the INOmax DSIR. The INOmeter uses a lower energy source which results in a lower IR beam range than the INOmax DSIR cart. The INOmeter does not transmit IR signals unless it is mounted on the INOmax DSIR cart. If there is interference with the INOmax DSIR/INOmeter communication, the cylinder icon on the user screen will not be displayed and a “Cylinder Not Detected” alarm will activate. If IR communication interference occurs, we recommend you take the following actions: • Move the external IR source • Move the INOmax DSIR cart to reduce the external IR source in the area of the INOmeter • Shield the INOmeter from the suspect IR source If the actions listed above do not remedy this issue, the Transport Regulator/Cap Assembly could be utilized (see page 41).

Part No. 20110 Rev-05 2014-02

External Light Interference High frequency and/or high intensity light emission in the area of the INOmeter may interfere with communication between the INOmax DSIR and the INOmeter on the INOMAX cylinder. If there is interference with the INOmax DSIR/INOmeter communication, the cylinder icon on the user screen will not be displayed and a “Cylinder Not Detected” alarm will activate. Test results have demonstrated susceptibility to unintended infrared energy from artificial light sources. Most notably, various compact fluorescent lighting fixtures that focus or reflect light, increasing the light intensity in the vicinity of the INOmax DSIR cart, could affect INOmeter communications. If external light interference occurs, we recommend you take the following actions: • Move the interfering light source • Move the INOmax DSIR cart to reduce the high intensity light in the area of the INOmeter • Shield the INOmeter from the suspect light source If the actions listed above do not remedy this issue, the Transport Regulator/Cap Assembly could be utilized (see page 41).

Theory of Operation The INOmax DSIR provides a constant dose of INOMAX into the inspiratory limb of the ventilator circuit. The INOmax DSIR uses a “dual-channel” design to ensure the safe 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 second channel is the monitoring system, which includes a separate monitor CPU, the gas sensors (NO, NO2, and O2 sensors) and the user interface, including the display and alarms. The dualchannel approach to delivery and monitoring permits INOMAX delivery independent of monitoring. This allows the monitoring system to shutdown INOMAX delivery, if it detects a fault in the delivery system. For example, INOMAX delivery will shut down should the monitored NO concentration become greater than 100 ppm. (See Figure 1-6 for a schematic diagram). 1. INOMAX drug is stored as a gas mixture of NO/N2 in an aluminum cylinder at a concentration of either 400 or 800 ppm. 2. The cylinder is attached to a high-pressure regulator, which incorporates a pressure gauge that indicates cylinder pressure when the cylinder valve is open. The cylinder regulator is attached via tubing to the INOmax DSIR using one of the two NO/ N2 quick connect inlets on the back of the device. 3. The INOmax DSIR checks the INOMAX cylinder for the correct expiration date and cylinder concentration. 4. INOMAX enters the back of the INOmax DSIR, passes through a filter, then a safety shutoff valve, which is open under normal operation. 5. An injector module is placed in the ventilator gas flow between the ventilator inspiratory outlet and the humidifier. Based on the ventilator flow, the INOMAX cylinder concentration and set INOMAX dose, the proportional solenoid valve delivers 800 or 400 ppm INOMAX into the ventilator circuit via the injector module where it mixes with the breathing circuit gas flow to achieve the set dose. This allows the INOmax DSIR to deliver a constant dose of INOMAX regardless of the ventilator flow pattern or breath rate (see figure 1-7).

Part No. 20110 Rev-05 2014-02

16

6. A flow sensor inside the INOmax DSIR also monitors the NO flow out of the machine. A check valve is included prior to the INOmax DSIR drug outlet to prevent pressure effects from the ventilator breathing circuit interfering with the NO flow sensor reading. 7. Gas Monitoring - The INOmax DSIR gas monitoring system provides monitored values for inspired NO, NO2, and O2. The sample gas is withdrawn from the breathing circuit and goes through a water trap, a zero valve, a sample pump and finally through a sample flow sensor to the gas monitoring sensors. • The zero valve allows the gas sensors to be zeroed (during low calibration) without having to disconnect the sample line from the breathing circuit. • The pump and sample flow sensor ensure a sample gas flow rate is maintained to the monitoring sensors. • The gas monitoring sensors are electrochemical; they are specific to each gas and provide an electronic signal which is proportional to the concentration of the gas present. 8. Backup Delivery - If the delivery system goes into shutdown, the INOmax DSIR has an integrated backup function which provides a fixed flow of INOMAX (250 mL/min) into the injector module using a pneumatic on/off switch and a restrictor which is built into the delivery side of the system. This fixed flow of INOMAX will provide 20 ppm of NO when using 800 ppm cylinders (10 ppm when using 400 ppm cylinders) when added to a continuous ventilator gas flow is 10 L/min. The backup is only for shortterm use until a replacement delivery system can be obtained. An alarm will warn the user if the backup system is turned on while the main delivery system is in use for INOMAX delivery. The INOblender can also be used as a backup.
