Can this unit be incorporated into a C-pap machine? If so, is it attached to the mask?
John - 10/2/2016 3:15:18 PM
answer image
Thank you for contacting customer care service.
The 525DS can be attached to a CPAP unit in one of 2 ways.
 1. The oxygen tubing can be attached directly to the mask if the mask has an oxygen port on it.
 2. It can also be attached to the air supply port on the CPAP unit using an oxygen adapter (part# 7353D-601). One end of the oxygen adapter is connected to the air supply port and the CPAP tubing is connected to the other end of the adapter. Finally the oxygen tubing is connected to the oxygen fitting on the adapter.

what type of the disposable humidifier bottle does this model use and what do I need to attach it to the concentrator?
priscilla - 1/18/2016 8:19:47 PM
answer image
Thank you for reaching out to us. It uses bubble humidifier bottle.
If your physician has prescribed an oxygen humidifier as part of your therapy, follow these steps (If using a prefill, go to step b.):
1). Fill the humidifier bottle with distilled water. Do not overfill.
2). Thread the wing nut located on the top of the humidifier bottle to the oxygen outlet so that it is suspended. Make sure it is securely tightened.
3). Attach the oxygen tubing directly to the humidifier bottle outlet fitting.
