2. Setting Up a Patient on Inogen At Home

2.1. Indications for Use

The Inogen At Home Oxygen Concentrator is used on a prescriptive basis by patients requiring supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal cannula to channel oxygen from the concentrator to the patient. The Inogen At Home Oxygen Concentrator may be used in a home or institution.

2.2. System Components

The following are standard components of the Inogen system:

• Inogen At Home Oxygen Concentrator
• AC Power Cord
• Humidifier Bottle (not included)
• Cannula (not included)

Patient Set-Up: To properly set up a patient on the Inogen At Home System, you may need to provide:

• Extra cannulas (not included)
• Extra output filters (not included)

2.3. Using the Inogen At Home

To quickly configure the Inogen At Home for patient use:

1. Place the concentrator in a well-ventilated location; air intake and exhaust vents must have clear access.
2. Attach the cannula to the nozzle fitting on the top of the concentrator or to the humidifier bottle, if using.
3. Connect the power cord to the Inogen At Home.
4. Plug into closest AC outlet.
5. Turn on the Inogen At Home by pressing the on/off button.
6. Use the + (increase flow) or – (decrease flow) buttons to adjust the Inogen At Home to the flow setting prescribed by the physician or clinician.

For further information regarding the use of the Inogen At Home, please consult the User Manual.

2.4. Selecting the Proper Flow Setting

The Inogen At Home can provide oxygen to the patient as long as a source of electricity is available. Because the oxygen is being produced as it is used, supply of oxygen is rate-limited. The Inogen At Home delivers up to 5 L/min of 90% (+6%/-3%) oxygen.

At each flow setting, the Inogen One generates a specific amount of oxygen (1 L/min per setting), which is delivered continuously to the patient. The device will deliver the same volume of oxygen regardless of the patient's breath rate.

3. Servicing the Inogen At Home

3.1. Maintenance by the Provider

• Humidifier Bottle (Salter Labs #7600)
• Nasal Cannula (Salter Labs 16SOFT)
• External Oxygen Analyzer (such as Salter Labs PrO2 Check)

3.1.3. System Inspection

At the start of any maintenance visit:

1. Be sure to ask the patient if they have experienced any difficulties in operating the equipment.
2. Be sure to ask the patient if they have observed any malfunctions or changes in characteristics of the equipment.
3. Visually inspect the device and accessories for cracks or other damage.
4. Feel the sides of the device for vibration and listen for unusual noises, rattles, or other signs that the device requires service.

3.1.4. Output Filter Replacement

This filter is intended to protect the user from small particles in the product gas flow. The Inogen At Home includes an output filter conveniently located behind the removable cannula nozzle fitting. Inogen suggests that this filter be replaced between patients.

Use the Output Filter Replacement Kit (RP-107) to replace the Output Filter:

1. Use the Cannula Barb Tool (included in RP-107) to access the product filter. The tool has two prongs which mate with two indentations located on the surface of the metal cannula barb fitting on the Inogen At Home.
2. Carefully remove the cannula fitting by unscrewing it in the counter-clockwise direction.
3. The filter, a hard plastic disk with a silicone gasket on its outer edge, will be visible in the recess once the hose barb is removed.
4. Remove the filter, and inspect the recess to make sure it is free of debris.
5. Install a replacement filter.
6. Carefully screw the cannula barb fitting back into the recess (clockwise) until it bottoms out on the filter gasket. Take care to squarely screw the nozzle fitting into the threads, and not to over tighten.

3.1.5. Oxygen Purity Check

The oxygen concentration can be checked using the Salter Labs PrO2 Check ultrasonic oxygen analyzer. The concentrator should be run for 10 minutes before measuring the oxygen concentration. If the concentrator has not been used for more than 2 weeks, the concentrator should be run for a minimum of 30 minutes to allow for adjustments to the operating parameters prior to measuring the oxygen concentration.

3.1.6. Air Inlet Filter Replacement

The inlet filter on the top of the concentrator (behind the handle) should be replaced when visually necessary (i.e. filter appears dirty) using the Air Inlet Filter Replacement Kit.

3.1.7. Column Change Procedure

There are two columns in the concentrator located behind the particle filter. These two columns should be removed and replaced when column service is required. Ensure adequate time is allotted to complete all steps without disruption when performing this maintenance.

1. Turn off the concentrator by pressing the power button.
2. Unplug the concentrator from the electrical outlet.
3. Lay the concentrator down on its side.
4. Press the two latch buttons on the sides of the device to remove the cover from the bottom of the concentrator in order to access the two columns.
5. Press the column latch button with thumb or finger and pull the column out of the concentrator using the pull ring attached to the column cap.
6. Remove the column completely from the concentrator.
7. Repeat steps 5-6 to remove the other column.

Installation of the new columns:

8. Remove the upper and lower dust caps from each column. There should be a total of two dust caps removed from each column. Make sure there is no dust or debris where the dust caps were located.
9. Insert the new column into the concentrator.

10. The column should click into place and the spring loaded latch button should fully return to the closed position when the column is completely inserted.
11. Repeat steps 9-10 to install the other column.
12. Replace the lower cover and return the concentrator to its upright position.
13. Connect the power supply cord from the concentrator and plug into an electrical outlet. Do not power on the concentrator.
14. Press and hold the plus (+) button for ten seconds. Flow indicators 1, 3 & 5 will be illuminated and columns will be reset. Release the plus button.
15. Press the power button to turn on the concentrator and use normally.

3.2. Maintenance by the Patient

3.2.1. Cannula Replacement

The nasal cannula should be replaced on a regular basis. A single lumen cannula of 4 to 100 feet in length must be used. Inogen has certified its performance data with the Salter Laboratories 16SOFT cannula.

3.2.2. Particle Filter Cleaning and Replacement

On the side of the Inogen At Home, ambient air passes through a particle filter that removes dust fragments. This particle filter must be cleaned on a weekly basis to ensure adequate air flow through the device. If the particle screen is not cleaned frequently, the life expectancy of the concentrator will be shortened due to higher internal operating temperatures.

Particle filters should be cleaned using a mild liquid detergent (such as Dawn™) and water solution; be sure the filter is rinsed in water and allowed to air dry before reuse. Additional replacement filters may be obtained from Inogen (RP-400). There are other types of filters inside the Inogen At Home that provide additional filtration. Maintenance of these filters is not required under normal operating conditions.

3.2.3. Humidifier Bottle Refill

The humidifier bottle should be routinely refilled according to the manufacturer's instructions.

3.2.4. Surface Cleaning

The outside case should be cleaned using a cloth dampened with a solution of mild liquid detergent (such as Dawn™) and water. Avoid getting water in or around the power jack or vents.

3.3. Expected Service Requirements

The following table is provided as an estimate only and assumes typical environmental conditions for temperature, humidity, and air pollution. Any smoking around the device will severely shorten its life expectancy. Please refer to product warranty coverage terms.
