Why Your Physician Prescribed Supplemental Oxygen
Today, many people suffer from heart, lung and other respiratory diseases. Many of these people can benefit from supplemental oxygen therapy. Your body requires a steady
supply of oxygen to function properly. Your physician prescribed supplemental oxygen for you, because you are not getting enough oxygen from room air alone. Supplemental oxygen will increase the amount of oxygen that your body receives. Supplemental oxygen is not addictive. Your physician prescribed a specific oxygen flow to improve symptoms such as headaches, drowsiness, confusion, fatigue or increased irritability. If these symptoms persist after you begin your supplemental oxygen program, consult your physician The oxygen delivery setting has to be determined for each patient individually with the configuration of the equipment to be used, including accessories.
The proper placement and positioning of the prongs of the nasal cannula in the nose is critical to the amount of oxygen delivered to the respiratory system of the patient Your Delivery settings of the oxygen concentrator should be periodically reassessed for the effectiveness of therapy.

How Your DeVilbiss Oxygen Concentrator Works
Oxygen concentrators are the most reliable, efficient and convenient source of supplemental oxygen available today. The oxygen concentrator is electrically operated. The unit separates oxygen from room air which allows high-purity supplemental oxygen to be delivered to you through the oxygen outlet. Although the concentrator filters the oxygen in a room, it will not affect the normal amount of oxygen in your room

SETTING UP YOUR OXYGEN CONCENTRATOR

1.  Position your unit near an electrical outlet in the room where you spend most of your time
   NOTE : Do not connect to an electrical outlet controlled by a wall switch.
   DANGER
   Oxygen causes rapid burning. Do not smoke while your oxygen concentrator is operating, or when you are near a person utilizing oxygen therapy. Keep the oxygen concentrator and cannula at least 2 m (6.5 feet) from hot, sparking objects or naked sources of flame.

2. Position your unit on a flat surface at least 6 inches (16 cm) from walls, draperies or any other objects that might prevent the proper flow of air in and out of your oxygen concentrator. The oxygen concentrator should be located in a well-ventilated area to avoid pollutants or fumes.
   NOTE : To move the unit, firmly grasp the handle located on the top of the unit, rolling and/or lifting the unit over pathway obstacles.

3. Before operating your unit, always check to be sure the filter door vents (located on the back of your unit) are clean. Proper cleaning is discussed in the Caring For Your Concentrator section on page 9.

4. Attach the appropriate oxygen accessories to the oxygen outlet
   Oxygen Tubing Connection:

   • Thread the supplied oxygen outlet connector onto the oxygen outlet

   •  Attach the oxygen tubing directly to the connector (Figure 1).
     Oxygen Tubing Connection With Humidification:
     If your physician has prescribed an oxygen humidifier as part of your therapy, follow these steps (If using a prefill, go to step b.):

   •  Fill the humidifier bottle as per manufacturer’s instructions.

   •  Thread the wing nut located on the top of the humidifier bottle to the oxygen outlet so that it is suspended (Figure 2). Make sure it is securely tightened

   • Attach the oxygen tubing directly to the humidifier bottle outlet fitting (Figure 3).
     NOTE: Your physician has prescribed either a nasal cannula or face mask. In most cases, they are already attached to the oxygen tubing. If not, follow the manufacturer’s instructions for attachment.
     NOTE: Your healthcare provider should verify the compatibility of the oxygen concentrator and all of the parts used to connect to the patient before use.

5.  Remove the power cord completely from the line cord strap. Make sure the power switch is in the “OFF” position and insert the plug  into the wall outlet. The unit is double insulated to guard against electric shock

WARNING
Ensure the mains power cord is fully inserted into the concentrator connector (230 volt units) and the power cord plug is completely inserted into a fully functioning AC wall outlet. Failure to do so may cause an electrical safety hazard
NOTE : (only 115 volt units) The plug on the DeVilbiss oxygen concentrator has one blade wider than the other. To reduce the risk of electric shock, this plug is intended to fit in a wall outlet only one way. Do not attempt to defeat this safety feature.

• To check your oxygen concentrator and accessories for proper operation; 1. Check the output flow by placing the end of the nasal cannula under the surface of a half-full cup of water and look for the bubbles. 2. Check the system for leaks by bending the nasal prongs over and squeeze tight to stop the flow of oxygen. Look at the flow meter to see that the indicator ball on the flow meter drops to zero. If the indicator ball does not drop to zero, check all connections for possible leaks. Parts to check for leaks are: tubing connections, humidifier bottle and other accessories like firebreaks. Repeat these steps until the flow meter ball drops to zero. Contact your provider or service supplier immediately if you encounter any problems.

WARNING
Improper use of the power cord and plugs can cause a burn, fire or other electric shock hazards. Do not use the unit if the power cord is damaged.

OPERATING YOUR DEVILBISS OXYGEN CONCENTRATOR

DANGER

•  Oxygen causes rapid burning. Do not smoke while your oxygen concentrator is operating, or when you are near a person utilizing oxygen therapy. Keep the oxygen concentrator and cannula at least 2 m (6.5 feet) from hot, sparking objects or naked sources of flame.
• DeVilbiss oxygen concentrators are equipped with a fire mitigating outlet fitting that prevents propagation of fire into the unit.

WARNING
When the unit is turned “ON”, as part of the normal start-up process, all three lights (Service Required, Low Oxygen and Normal Oxygen) on the front panel should illuminate and the audible alarm should sound. If ANY of the lights on the front panel DO NOT illuminate or the audible alarm DOES NOT sound, this indicates the alert system is not functioning properly. Refer to the Troubleshooting chart on page 10 and contact your DeVilbiss oxygen provider if necessary.

1. Press the power switch to the “ON” position. When the unit is turned “ON,” all three lights (Service Required, Low Oxygen and Normal Oxygen) on the front panel will illuminate briefly and an audible signal will briefly alarm confirming that the LEDs and audible signal are functioning properly. The unit will then operate in “start up” mode with the Low Oxygen light lit until a normal oxygen level is achieved, at which time the Normal Oxygen light will remain lit. The “start up” may take up to 15 minutes.
   NOTE – DeVilbiss recommends for optimal service life that the DeVilbiss Oxygen Concentrator be operated for at least 30 minutes after it is powered ON. Shorter periods of operation, operating in extreme temperature/humidity conditions or in the presence of contaminates, and/or handling and storage conditions outside those specified, may affect the long term reliable operation of the product.
   DANGER
   Oxygen makes it easier for a fire to start and spread. Do not leave the nasal cannula or mask on bed coverings or chair cushions if the oxygen concentrator is turned ON but not in use, the oxygen will make the materials flammable. Turn the oxygen concentrator OFF when not in use to prevent oxygen enrichment.
   NOTE – If the audible signal alarms but the unit is not operating, there is no power to the unit. Refer to the Troubleshooting chart on page 10, and contact your DeVilbiss provider if necessary.
   NOTE – If an audible low-frequency vibration sound is detected, the unit is not operating properly. Refer to the Troubleshooting chart on page 10, and contact your DeVilbiss provider if necessary.

2. Check the flow meter to make sure that the flow meter ball is centered on the line next to the prescribed number of your flow rate.
   CAUTION
   It is very important to follow your oxygen prescription. Do not increase or decrease the flow of oxygen – consult your physician.
   NOTE – Your DeVilbiss provider may have preset the flow meter so that it cannot be adjusted.
   NOTE – If the flow meter knob is turned clockwise, the flow decreases (and eventually will shut off the oxygen flow). If the knob is turned counterclockwise, the flow increases.
   NOTE – For prescriptions of 5 LPM, be sure the ball is centered on the 5 liter line. The ball should not touch the red line. Setting the flow higher than 5 may cause the oxygen purity level to drop.
   NOTE – The low-flow alarm may activate if the flow meter ball is set at or below 0.2 lpm. The unit will continue to run; however, the Service Required light will come on accompanied by an audible alarm. Adjust the flow meter to your prescribed flow.

3. Your DeVilbiss concentrator is now ready for use, properly position the cannula with the nasal prongs facing upward, insert the prongs into nose. Wrap the cannula tubing over the ears and position in front of body. Allow 15 minutes for the oxygen concentrator  to reach stated performance.

DeVilbiss OSD® Operation

The OSD (Oxygen Sensing Device) is a device within your concentrator that monitors the oxygen produced by your unit. The OSD lights on the top panel are defined as follows:

1. Green Normal Oxygen light–acceptable oxygen level.
2. Yellow Low Oxygen light– below an acceptable oxygen level.

If the oxygen purity falls below the acceptable level: The green Normal Oxygen light will shut off, the yellow Low Oxygen light will illuminate, and an intermittent audible signal will sound.
Refer to the Troubleshooting section in this guide on page 10, and switch to your reserve oxygen system. Do not attempt any other maintenance. Contact your DeVilbiss provider immediately.

PROVIDER’S NOTES – Cleaning and Disinfection When There is a Patient Change
NOTE – Recommendations for preventative maintenance at 3-year intervals are outlined in the Service and Maintenance Guidance below.
DeVilbiss Healthcare recommends that at least the following procedures be carried out by the manufacturer or a qualified third party between uses by different patients.
NOTE – If the following described complete processing of the concentrator by an appropriately trained individual is not possible, the device should not be used by another patient.
NOTE – If preventive maintenance is due at this time, these procedures should be carried out in addition to the servicing procedures.

1. Use disinfectants safely. Always read the label and product information before use

2. Always wear personal protective equipment when performing this procedure. Use suitable gloves and safety glasses. Cover exposed skin on arms to prevent accidental contact with bleach solution that has been applied to the concentrator.

3. Dispose of all accessories that are not suitable for reuse. This includes but may not be limited to the oxygen tubing, tubing connectors, nasal cannula and/or mask, oxygen outlet connector, and humidifier bottle.

4. Clean the exterior of the concentrator with a clean lint-free cloth. Heavy soil should be removed with a clean lint-free cloth dampened with water. A soft bristled brush dampened with water can be used to remove stubborn soil. Dry the concentrator using a clean lint-free cloth if water was used to remove soil

5. Use 5.25% chlorine bleach (Clorox Regular Liquid Bleach or equivalent). Mix one (1) part bleach with four (4) parts water in an appropriate clean container. This ratio produces a one (1) part bleach to five (5) total parts solution (1:5). The total volume (amount) of solution required is determined by the number of concentrators in need of disinfection. NOTE – An alternate suitable disinfecting agent (e.g. Mikrobac® forte or Terralin® Protect) may also be used. Follow disinfectant manufacturer’s
   instructions.

6. Apply the bleach solution in an even manner to the cabinet and power cord using a clean lint-free cloth. The cloth should be dampened only and not dripping of solution Do not use a spray bottle to apply the solution. Do not saturate the device with the solution. Take care that no solution enters the vent areas on the concentrator base or
   the Auxiliary O2 fitting area on the back of the unit. Avoid over-saturating the cabinet seams so that no solution residue builds up in these areas. Avoid the caster wells located on the bottom of the unit.

7. Exposure time of the disinfectant solution should be 10 minutes minimum to 15 minutes maximum.

8. After the recommended exposure time, all surfaces of the concentrator should be wiped with a clean lint-free cloth dampened with drinking quality water no warmer than room temperature. Dry the unit with a dry, clean lint-free cloth. This is to remove residue that may stain or leave a film on the unit, especially after repeated disinfections.

9. Check the cord, the plug on the back of the device, the power switch, the fuse holder, and the indicator lights for possible damage. Replace all damaged or worn components

10. Check the oxygen concentration. If the device is within specification, the extended life intake bacteria filter does not need to be replaced between patients. If the oxygen concentration is not within specification, the provider should refer to the service manual section on Troubleshooting.

NOTE – There is no portion of the gas pathways through the concentrator that could be contaminated with body fluids under normal conditions.
The device patient connection may unintentionally become contaminated with expired gases for a single fault condition i.e., a hose internal to the device becomes
disconnected. This condition will cause no flow out of the device and/or an alarm condition. Should this occur, refer to the service manual for additional instructions.

Disinfection

NOTE – The disinfection process can only be completed by the manufacturer or by an appropriately trained individual.

SERVICE AND MAINTENANCE GUIDANCE

Service and maintenance should only be performed by appropriately trained and authorized Drive DeVilbiss personnel and/or service centers

| Recommended disinfection interval| Number of disinfection cycles| Compatible disinfection method
---|---|---|---
Cabinet, power cord| Between patients| 20| 1:5 chlorine bleach (5.25%) and water solution, Mikrobac forte, Terralin Protect
Oxygen tubing, tubing connectors, nasal cannula/mask, oxygen outlet connector, humidifier bottle| Do not clean, replace between patients| N/A| N/A

Some models of 525 series concentrator do not require a gross particle filter. This information is noted in the user manual.
Sieve bed, compressor cup seal, compressor filter and final HEPA filter service should only be performed by appropriately trained and certified Drive DeVilbiss service centers.
NOTE – This is a suggested maintenance and service schedule for home oxygen providers. Individual maintenance requirements may vary based upon local operating conditions, regulations, or other circumstances.

Initial Inspection

1. Upon receiving, examine the unit for external damage. If the unit appears to have external damage, please contact DeVilbiss for assistance

2. Check to be sure the cabinet air filter (if applicable) and the intake filter are in place.

3. Plug the unit into an electrical outlet, turn the unit “ON” and check the audible/visual alarms. When the unit is turned ON, as part of the normal start-up process, all three lights (Service Required, Low Oxygen and Normal Oxygen) on the front panel should illuminate and the audible alarm should sound. If the ANY of the lights on the front
   panel DO NOT illuminate or the audible alarm DOES NOT sound, this indicates the alert system is not functioning properly. Refer to the Troubleshooting chart on page 10 or contact DeVilbiss for assistance.

4. Set the flow meter at the maximum recommended flow rate and allow the unit to run for 20 minutes. The internal oxygen sensor monitors the oxygen purity. If the oxygen is within specification, the Green Normal Oxygen light will be illuminated. If the Yellow Low Oxygen light is illuminated, refer to the Service Manual or contact DeVilbiss for assistance.

5. With unit still running, unplug to test the power fail alarm. If the power fail alarm does not provide an audible alert, refer to the Service Manual or contact DeVilbiss for assistance.
