After a decade watching patients quit CPAP, I finally understood why the machine was never the answer.
By Dr. Sarah Harris, MBBS, MRCP — Consultant in Sleep and Respiratory Medicine
50% of CPAP patients quit. That's not their fault. The machine is fighting the wrong problem
When you fall asleep, the muscles holding your lower jaw relax.
Your jaw drops backward. Your tongue follows it. The airway closes.
That's the choking. That's the gasping. That's the oxygen dropping.
The only way to stop it is to keep the jaw slightly forward — so it can't fall back in the first place.
It's exactly what a paramedic does in an emergency. They call it the jaw-thrust manoeuvre. It opens a blocked airway in about a second.
AirVex does the same thing. Gently. All night.
CPAP forces pressurised air down a closed airway.
It's fighting the problem. Not fixing it.
That's why the pressure keeps ramping up. Why the mask leaks. Why you rip the mask off at 3am.
If you couldn't stick with CPAP, It's not your fault.
The machine was built to fight the collapse.
AirVex prevents it.
Home sleep test, same patient — before and after 4 weeks of using AirVex.
In our clinical testing, users saw their AHI drop by an average of 87% within 4 weeks.
Even severe cases landed at an AHI of 3 to 5.
The reason is simple. The jaw can't fall backward. The airway can't close.
There's no apnoea event to record.
The best treatment in the world doesn't work if you can't wear it.
That's why half of UK CPAP users quit.
The mask leaks.
The straps mark your face.
The pressure ramps until you wake up gasping.
Air gets forced into your stomach so hard it bloats you.
Dry mouth every morning. Hair matted from the headgear. The hose pulls when you roll over.
Most people end up ripping the mask off every night at 3am.
AirVex is made from a soft, ultra-thin material that sits inside your mouth.
Most users forget it's there by the third night.
If you have sleep apnoea, you're 4x more likely to die of a heart attack in your sleep.
You're 3x more likely to have a stroke.
You're 2x more likely to die from any cause.
Most of these deaths happen between midnight and 6am.
The exact hours your airway is closing.
AirVex stops sleep apnoea at the source.
For the first time in years, your body actually sleeps.

"AHI went from 29 to 4 in four weeks"
I was put on antidepressants at 38. By 42 I'd tried four different ones. My husband kept telling me I was gasping in my sleep. My GP said it was anxiety.
I got a sleep study done privately. AHI of 29. Moderate to severe.
The NHS gave me a CPAP. I lasted five weeks. The mask bruised my nose. The air forced into my stomach made me sick. I'd rip it off at 2am without realising.
My sleep clinic said there was nothing else they could offer.
I found AirVex on a forum. Ordered it that night.
Four weeks later I did another home sleep test. AHI down to 4.
The brain fog is gone. I can finish a sentence without losing the word. My husband says I'm a different person.

"Bought this for my mum who wouldn't wear the CPAP"
Mum's 66. She started snoring badly after menopause. Dad moved to the spare room three years ago. Her sleep study came back at AHI 19.
The NHS gave her a CPAP last year. She wore it twice. Said it made her feel claustrophobic and sick. It's been in its case ever since.
She kept saying she was fine. She wasn't fine. She was falling asleep at Sunday lunch. Forgetting her grandchildren's names. I could hear her stop breathing when I stayed over at weekends.
I ordered AirVex without telling her. Drove over with it on a Saturday.
She's worn it every night for three months. Had another sleep study last week. AHI down to 5.
Dad's back in their bedroom. She says she hasn't felt this sharp in years.

"My wife's snoring nearly broke us. This fixed it in a week."
My wife started snoring about five years ago. Got worse every year. By last winter I was in the spare room every night. Neither of us said it but the marriage was falling apart.
Her GP referred her for a sleep study. NHS waiting list was 11 months. She was waking up with headaches every morning. I wasn't waiting 11 months.
I bought her a mouthguard off Amazon. She said it was like a golf ball in her mouth. Threw it out after two nights.
Then I found AirVex. She was sceptical but tried it.
First night — silence. I lay there waiting for the snoring. It never came.
Four months in. Headaches gone. Energy back. We're in the same bed again.
Best £30 I've ever spent.

"My GP kept telling me I didn't fit the profile"
I'm a marathon runner. Fit. Thin. Not the person GPs expect to have sleep apnoea.
But I've been exhausted for years. Waking up gasping. Morning headaches. Brain fog I couldn't shake.
My GP refused a sleep referral three times. "You don't fit the profile."
I went private in the end. AHI came back at 8. "Borderline. No treatment indicated."
I bought AirVex after reading a forum thread.
Two weeks in, the morning headaches were gone. My husband said I'd stopped waking him up in the night. First proper sleep in years.
