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.
CAUTION
Availability of an alternate source of oxygen is recommended in case of power
outage or mechanical failure. Several certifying bodies for Home Health Care
Providers require that back-up oxygen be available to the patient.
2.2. System Components
The following are standard components of the Inogen system:
o Inogen At Home Oxygen Concentrator
o AC Power Cord
o Humidifier Bottle (not included)
o Cannula (not included)
Patient Set-Up. To properly set up a patient on the Inogen At Home System, you may
need to provide:
o Extra cannulas (not included)
o 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.

this period, Inogen recommends making arrangements to bring an extra oxygen
supply.
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.
CAUTION
Discovery of cracks or other types of external damage may be indicative of other
internal damage that may not be visible. If such external damage is discovered,
be certain to inquire as to how it occurred, and whether any changes in the
device have been noticeable since its occurrence. If you have any concern over
the safety of the device, arrange for equipment servicing.
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 counterclockwise 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.
CAUTION
Failure to inspect and replace the product filter may result in the filter becoming
clogged or obstructed over time, and in reduced delivery of oxygen to the
patient.
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.
CAUTION
Do not leave the column exposed after the dust caps are removed; it should be
inserted into the concentrator as soon as the dust caps have been removed to
minimize environmental exposure and maximize lifespan.
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.

NOTE
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.
CAUTION
Do not use total cannula tubing length exceeding 100 feet with the Inogen At
Home unless proper saturation has been verified by a clinician.
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 DawnTM) 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 DawnTM) 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
