The S9 APAP machine provides exceptional results without hassle, complication or discomfort.

AutoSet Technology

AutoSet technology works in concert with Easy-Breathe expiratory pressure relief to deliver optimal pressure levels throughout the entire course of therapy. AutoSet is an advanced algorithm which carefully surveys and monitors the particulars of your breathing behavior and then adjusts according to your needs. What's more, the AutoSet also has the capacity to differentiate between obstructive sleep apnea (OSA) and central sleep apnea (CSA) and will respond appropriately to each type of occurrence.

Easy-Breathe Technology

Easy-Breathe expiratory pressure relief (EPR) provides pressure adjustments so that patients can better adapt to therapy. Easy-Breathe will consistently reduce pressure levels during exhalation and then elevate them thereafter; Easy-Breathe monitors your particular behavior and provides adjustments based on your individual needs.

Mask-Fit System

The S9 AutoSet APAP machine is capable of accommodating all three basic mask styles - Nasal, Pillow and Full Face. Simply adjust the setting on the machine to correspond with your particular mask and then the Mask-Fit system will ensure that your mask seals properly. The Mask-Fit system will also help detect fitting issues so that you can address such issues before you begin therapy.

Data Management

It's critically important that all sleep apnea patients take an active role in monitoring their progress and keeping track of their therapy data. The S9 AutoSet APAP machine greatly simplifies these tasks with its advanced data management capabilities. The S9 comes with an SD card and can store up to 365 days of therapy and compliance data, 30 days of detailed data and 7 days of flow data.

I read that resmed machines are the best and I just got diagnosed with sleep apnea so I went with the resmed auto one. I didnt use a humidifier in my sleep study so I didnt know if I needed it, and it was cheaper without it. I talked to the girl on the phone who said I can always add it later so I just bought this standard one without the humidifier. Not sure if I need it but if I can add it later and just buy it separately that is nice. Anyway just started using the machine this past week and I can already say I feel a lot better in the mornings. I was scared when I got diagnosed but now I think it will work out ok. I will also review the mask I gave so you guys know how helpful you are. Thanks
