Is this like a WOWYHI thread?

You seem quite knowledgeable about this.
My brief stats this morning were an average of 24 stoppages of breathing per hour, many from 30-60 seconds long.
I'm not overweight, I run regularly, including marathons. Not gonna say I'm a 10/10 on fitness scale, but I'm above average, therefore it's genetics the problem.


Assuming that you are referring to an apnea-hyponea index of 24, that would be considered moderate sleep apnea. Untreated, it would probably become worse as weight, blood pressure, and chronic fatigue will likely increase.

Doc just said I stopped on an average of 24 times. 18-30 is considered moderate.
0-5 is good

Yes. They didn't come in during the middle of the night to save me with a CPAP, so I must not have a terrible case of apnea. However, I have to come back for a second night and wear the CPAP. I didn't sleep well last night at all. Just because they didn't come in and put the cpap on you doesn't mean that you didn't have apnea. It depends on how the dr ordered the test it was probably a 2 night study so they monitor you the first night and spend the second night doing the titration.


Not necessarily.

Insurance is the main deciding factor determining whether you have a 2-night study or a split-study.

Let me put it this way, if your insurance will pay for a 2-night study, regardless of the the severity of the sleep apnea, you will get a 2-night study. $$$

An AHI of 5 or greater is enough to diagnose someone with sleep apnea. In reality, once this threshold is established, they SHOULD stop the rule out portion of the test, and commence the CPAP titration portion. Some insurance require this, others don't. Guess who gets to come back for another night at the lab?

your scare the Cpap out of persons needing a machine setting is very inappropriate. google Cpap pressure to high and you get 466000 responses describing the issues. most important issue is fit for comfort and leakage. a quote high pressure setting requires the use of a face mask designed for high pressure which is not common . if a newbie user is still uncertain, the auto titrate Cpap machines very common,,, will fit the bill quite nicely just a few more dollars. relying on a service provider to set pressure is not helpful when traveling as elevation changes automatically increase set pressure.

its not uncommon to see experienced drivers fall asleep in the middle of the day and cross the median for a head on crash. before Cpap I too woke up a couple times in the grass at 70 miles per hour. Cpap is a simple system, and folks need to be encouraged to use ,,,scaring the Cpap out of them is unfortunate



Yep, I have no idea what I'm talking about. I should just "Google" it, instead of relying on my 20 years doing this for a living.

Let me make this perfectly clear. No one should ever acquire a CPAP and set the pressure to whatever makes the mask comfortable or seal. Recipe for disaster.

I would expect a lot of rolling around and trying to think of total blackness to try to go to sleep which never works because you will be thinking about how you need to go to sleep.

...my 20 years of doing this for a living....I appreciate that you acknowledge you are in the Cpap sales/service arena.

in year 2000, its commenly quoted that 800000 car crashes occurred with poor quality sleep identified as a contributing factor. of this 1400 incidents resulted in death with 940 lives that could have been saved with Cpap usage. that's what I call a disaster. I was unable to find any specific correlation of set pressure improper use to fatality rate.

scaring the Cpap out of individuals to drive them towards a service/rental provider is not kosher. think of how many untreated drivers that will run the highways as a result

I once had a car salesmen test drive my trade in vehicle. when the the deal fell apart due to pricing on the new car, he tried to strong arm me by claiming my used vehicle was not road worthy and he would not return the keys. I had the police show up to cite the salesmen for theft. this Cpap disaster claim is a whole lot like that car salesmen

I'm starting to think you are in far more need of a good psychiatrist, than a sleep disorder doc.

What in the Hell are you talking about? "Scaring the CPAP out of individuals"?

Are you self-adjusting your lithium also?

It's a terrible night of "sleep".

I had to take it twice because the first time I never fell asleep with all that bullshite hooked to my skull. Ask for an ambien. They will give you one and it will help immensely.

What your uneducated mind is failing to understand is, an improper dosage (cpap pressure) will result in one of two things. Obstructive sleep apnea won't be treated. Great you just wore a cpap and it didn't do any good. Second, you now have Central Sleep Apnea and now your brain is tricked into thinking you don't need to breath. Congrats! You still aren't breathing when you sleep.

You do not set a cpap pressure to whatever makes the mask fit and seal!

I have advocated for auto-cpap, a cpap that self regulates the pressure. But a lot of docs won't write for those without a sleep study first. I person could have CSA, then an auto would not do any good, and a bi-pap would be needed.

My score was 60. 6' 165lbs, yeah I am a fatty.

I did the home test, glad I did. I no longer snore, wife would sleep on the couch 6 out of 7 nights a week.
I feel much more rested. I have the air sense auto pap as well as and use a full face mask.

I too thought it was a scam until I used it for a few weeks.

That's not uncommon.

I don't know how anybody sleeps in a study without some help from meds.

They do a full EEG, EKG, a band across your chest to measure respiration, a pulse ox sensor on a finger, then tell you a camera is pointed at you, and attempt to force you to sleep flat on your back.

How much trouble did you have getting that glue out of your hair?

I didn't take any meds like melatonin, for I figured it would affect the true results.
The glue did scrub out with hot water in the shower and shampoo.

Side note, a few years ago, the normal procedure for diagnosing sleep apnea was a 2 night sleep study. Insurance finally wised up, and started requiring a split-night study. Cut the cost in half, much to the outcry of the sleep labs. There has been no discernible difference in treatment or outcome since them, despite the protest of the sleep labs. They have been fighting home sleep testing for as long as I can remember, also. Gotta protect that cash cow.

I use Kaiser Permanente Mid-Atlantic (HMO). This is why they didn't require me to do an in-house sleep study. I did a five night home study instead. Cheaper for them and more convenient for me.

Wow, who does a full EEG? That’s a complete waste of time and space. Full EEG is 32 leads. I hook up 9 EEG, 2 EOG, and 3 EMG.

Shouldn’t be using collodion anymore. It’s really not needed. Hypafix will hold all night with 10/20. If you’re talking about conductive paste, 10/20 or Elefix, hot water should get most of it out. If there is some that’s being stubborn, use acetone to get it out.

I've got a full face mask. The original ENT I saw sent a scope up my nose and laughed saying I had "seen trauma" (broke my nose 3 times playing water polo). I have obstructed air movement in my nose so the small lines won't work on my.

As soon as I get the mask on it's like I have to scratch my nose from a fantom itch.

Thing has worked wonders for me.

Ask if you had any central or mixed apnea. If it was strictly obstructive, ask to be treated with APAP. If you have central or mixed, you’re going to need that second night to titrate you. You likely won’t need a CPAP. A Bilevel, Bilevel with backup rate, Bilevel AVAPs, or Auto-SV might be needed. Each of those have a lot of different settings as well.

Generally we start low and bump until we eliminate all events. Sometimes you’re fixed with as low as 8-10cm. Sometimes we max that damn thing out and you still quit breathing.

My problem with this is it is not direct pressure. It typically takes a lot more pressure to titrate because you have to take the air in yourself. A lot of times the same person can use MUCH less pressure with nasal pillows.
