I'd like to try adding EERS (Enhanced Expiratory Rebreathing Space) to my BiPAP setup (ResMed AirCurve 10) to see how I respond to higher PS levels (>5).

At PS = 6-7, my breathing feels significantly better, but unfortunately I start getting more central apneas (CAs).

Does anyone know where I can buy the following components in Europe?

• Whisper Swivel II exhalation port
• Short tubing sections (6-inch length), such as 22 mm Corr-A-Flex tubing, or any similar tubing that can be easily purchased locally
• CPAP connectors/adapters for this tubing
• Anti-asphyxia valves (safety valves)

BiPAP batteries are unfortunately very expensive. Does anyone know of any power banks or alternative battery solutions that are compatible with the AirCurve 10?

Any recommendations for European suppliers or stores would be greatly appreciated.

I suspect I may have UARS and I've been experimenting with BiPAP while waiting for an in-lab sleep study scheduled for early August.

For many years I've had symptoms that look a lot like ADHD and depression:

• poor concentration
• brain fog
• low motivation
• feeling unrefreshed after sleep
• anxiety upon waking

As a child, I was a chronic mouth breather because of an enlarged adenoid (which was eventually removed). I developed a significant overbite/retruded jaw and I suspect I may also have a narrow maxilla because nasal breathing has always felt somewhat difficult.

Current setup:

• Bleep Eclipse mask
• Mouth taped with Nexcare Waterproof (Medium Hold)
• Leaks are usually very low or nonexistent

Current BiPAP settings:

• EPAP = 6
• PS = 5
• IPAP = 11

With these settings, one thing has definitely improved: the anxiety I used to feel immediately after waking up has become much smaller and is now barely noticeable most mornings.

However, I still wake up about twice per night and I don't feel refreshed in the morning. It feels like sleep is still not restorative.

I've been stuck at this point for at least a week with no further improvement in concentration, brain fog, or daytime functioning.

I tried increasing EPAP from 6 to 7 and lowering PS from 5 to 4. As soon as I do that, I start getting mild aerophagia (air in my stomach, urge to burp), which eventually puts me into a hyper-alert state and prevents me from falling asleep.

PS = 5 feels comfortable.

PS = 6 feels like too much.

My questions:

1. Would you continue experimenting with EPAP and PS, or stay at these settings longer?
2. Has anyone with UARS experienced aerophagia when increasing EPAP, and how did you solve it?
3. Looking at OSCAR data alone, is it possible to estimate whether I am getting enough REM sleep?
4. Can OSCAR provide any clues about RERAs or other arousals without EEG?
5. Has anyone with UARS and ADHD/depression-like symptoms experienced significant improvement only after finding the right BiPAP settings?

I've attached OSCAR screenshots from two nights.

Any feedback would be greatly appreciated.
