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, 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 flters the oxygen in a room, it will not affect the normal amount of oxygen in your room

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 fllowing described complete processing of the concentrator by an appropriately trained individual is not possible, the device should not be used by another patient.

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 ofconcentrators 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 fuids 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 fow 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.
