Update after one year of using the 6” AlaxoStent with my VAuto. I’m not signing in much anymore, since things are going perfectly. Here is a summary:
First year results
In the 30 days prior to my using the 6” AlaxoStent my machine scored 489 Obstructive Apneas, despite my 99.5% Flow limitation averaging 0.019. That indicated to me that PAP pressure was correct for inspiration, but expiratory Palatal prolapse was closing down my throat.
I then started the AlaxoStent on Dec. 16, 2021. In the year since starting stent use (combined with VAuto) my total Obstructive Apneas have been 7, and my 99.5% Flow limitation is averaging 0.032 (median pressure 7.48).
So, use of the stent with my bilevel brought down my Obstructive Apneas from 489/month, to 7/year, all while decreasing my average pressure on my VAuto (with the side benefit of no more air leaking into my belly at high pressures).
OSCAR calculates my average AHI over this past year is 0.042. That included early days of going down to as low as 3cm CPAP, to see how well the stent was doing on its own, with Hypopneas appearing at that low pressure. Since dialing in my current pressure (over ten months ago to EPAP 4 & PS 3.6cm), my AHI has averaged 0.022. Occasional random, short, CA’s or H’s slip through on some nights, but I’ve had a whopping 293 nights of 0.00 AHI in the past year. Over 86% of my nights since the pressure change 10 months ago have been 0.00 AHI!!!
I have not noted any negative side effects from use of the stent. No nasal or throat infections, for example.
A previous post mentioned that I had a sleep study with the stent alone, and it brought my AHI down from severe to mild - so sometimes I take naps without masking up, knowing I’m doing ok. I wear my O2Ring so I that’s how I know I’m doing OK.

Sleep study in 2010 (11cm CPAP). Pillows (Swift FX>TAP PAP >Bleep). PRS1 “Pro” 450/460 until recall, now Aircurve 10 VAuto. Tape mouth. Palatal Prolapse solved by AlaxoStent & VAuto EPAP 4cm, PS 3.6cm = 0.0 AHI
