I agree with NHe about why your doctor told you she'd be looking for desats of a certain number of points, Paul B. Keeping 02 levels up is the utmost concern, of course.

That's probably so about a good many limited flows, which is what an hypopnea is. However, I think it's important to eliminate hypopneas that cause arousals without any significant desats involved. Arousals can wreck sleep architecture. Enough of them and a person could wake up in the morning not feeling rested at all, even if they didn't have much/any dip below 90% in their O2 sats all night.

One of several definitions of an hypopnea is:

from sleepydave:
"The definition of a hypopnea varies a bit, but generally, it's a 50-80% reduction in breathing, with a desaturation and/or an arousal." (bold emphasis, mine)
http://www.apneasupport.org/viewtopic.php?p=2827

So, hypopneas can interrupt smooth sleep by causing just an arousal, without a dip in oxygen saturation.

Explaining "arousal", sleepydave writes:
"An arousal is simply a 3 to 15 second break in sleep continuity, and an awakening is 15 seconds or more. It's usually to an alpha pattern. You may be aware of awakenings (not to be confused with really being "awake") but you won't be aware of arousals.

A hypopnea needs either an arousal and/or a desaturation to be scored as such. In adults, virtually all respiratory events will be terminated by an arousal (the rule kind forces that issue)."(bold emphasis, mine)

Your doctor is right to be looking for significant desats, Paul B, as lack of sufficient oxygen during sleep can be very damaging to every cell in the body. Gotta keep that heart and brain in particular well oxygenated!

A fellow EFFORTS member passed this on to me:

Sky_Man, What is EFFORTS? Thanks.

I notice the recording interval is patient settable between 1,2,5 or 10 seconds. Naturally the memory will fill up faster based on what interval is chosen, but what setting would balance useful data versus memory constraints.

LOL. First we'd have to know how much memory the device has, wouldn't we?

Bill, it's got enough to handle any of those four settings, depending how long you sleep. The question is how many nights of data it will hold at any particular setting. LOL at your LOL.

Jeepdoctor, here is the EFFORTS website:

I just talked to Turner Medical. The CSR says that the oximeter will record 8 hrs data at one second intervals and spit it out in the 4 formats shown on their site. He also said that they have a 30 day return policy. This is sounding better and better. Certainly better than investing in the stock market.

I looked at some Nellcor 595's on eBay. Problem is that if one wants to move the data from the Nellcor to their PC, it requires software like Profox, which is around $ 375.

OK, I'm convinced. Everything else about the unit I've seen looks good. If this little jewel had been around last year I probably wouldn't have considered getting the N-395 I've got. I'll be surprised if we don't start seeing the price of used oximeters drift downward now.

Ditto! Wish I had seen it before buying the used Nellcor.

If this lives up to its marketing material this could be a "must have" for only the price of 2 RESMED masks.....

We will know more about the 7500 in a few days.

There is one on the truck with my name on it!

Alright!!!

Let us know, David.

Yes, I agree, this unit looks very impressive. I just ordered one for myself, $425. and no shipping charge. 24/7 tech. support is included also.

Have any of you had insurance cover an oximeter? What did you have to do to get it covered?

Unless I have a MAJOR expense insurance deductable lets (requires) me to spend my money.
