Devilbiss Osd ® Operation; Reserve Oxygen System - DeVilbiss Healthcare 525 Serie Guía De Instrucciones

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 Minor Troubleshooting chart on page 9 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 Minor Troubleshooting chart on page 9, 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 (Figure 4). 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:
• Green Normal Oxygen light–acceptable oxygen level.
• 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, and the yellow Low Oxygen light will illuminate . Switch to your reserve oxygen
system . Refer to the Minor Troubleshooting section in this guide on page 9 and contact your DeVilbiss provider .
As an added safety feature, should the oxygen purity continue to drop, an intermittent audible signal will sound . Contact your DeVilbiss provider immediately . Do not attempt
any other maintenance .

RESERVE OXYGEN SYSTEM

As a precaution, your DeVilbiss provider may supply you with a reserve oxygen system . If your unit loses electrical power or fails to operate correctly, the Patient Alert System
will sound to signal you to switch to your reserve oxygen system (if provided) and contact your DeVilbiss provider.
