Poll on Oximetry Usage - Netskier - 03-23-2012
The thread about "CO2 and Central Apneas", plus the thread " Shouldn't the goal of PAP treatment be to minimize Obstructive Apnea?" have made me wonder how many members here use Oximetry. So I made a poll to ask this.

Would be lost without my Oximeter, it does give vital information and I also like to go without my machine sometimes just to see if the apneas are really bad but sometimes I have a real good night without my machine.

I am thinking about getting an Oximeter for a more complete picture of what if any are the effects on my Central Apneas. They are pretty expensive!
RE: Poll on Oximetry Usage - cbramsey - 03-25-2012
The only time I use an oximeter is during sleep studies where I am wired up. I have never used one at home.
Your mileage may vary.

the cms50 series of pulse oximeters apparently work with sleepyhead. i'd appreciate it if the pulse ox users that are using one and incorporating it into sleepyhead would talk about which model (e, f, etc) seems to work the best and is most cost effective. i hate to pay for the newest if the next one down is just as good. thanks.

I would like to learn this too. I got the impression somewhere, perhaps from reading the Sleepyhead material, that the CMS50 series was about fifty bucks.
I am almost holding my breath waiting for Jedimark to return to action.

Different things can affect it.. Check the leaks and snore graphs, pressure pulses (bright red dots) and other surrounding events for more clues. eg, you could pull the mask up for a few seconds, and it will skip the breath.. you could be rolling over, awake and concentrating hard, etc...
The clinical definition of an obstructive apnea, is major reduction in airflow (<10% of baseline) for at least 10 seconds, accompanied by an oxygen desaturation of 3 or 4%.
Hypopnea is similarly defined, with a reduction to <50% of baseline.
It's the oxygen desaturations that really matter, as this is what causes the damage made by OSA/CA. If your worried, invest in an oximeter if you haven't already.. I recommend the cheap Contec CMS50's.. (at least a D+, with a usb port), available from eBay and everywhere else.
SleepyHead has a few tricks to get the oximetry data to compare against CPAP.. My current favourite method is starting both CPAP and oximeter recording at the same time. Import the CPAP data first, and then when you import the oximeter, it will pick the starting time of the CPAP session. This is the most accurate sync method I've found..
Even when it's synced, the SpO2 (oxygen saturation %) is delayed by 15 seconds or so, as the blood at your fingertip represents what was at your heart back when that blood was pumping through. (The actual time of this delay depends on your blood pressure, size of arteries/veins, and the length of your arms)

pretty sure we want the e or f model. remember when looking at oximeters, they mostly say for sports use, not for medical use. the reason is the mfgr is doing an end run around calling it a medical device and getting into the prescription arena. whether it says sports or medical it measures o2 sat the same accurately.
RE: Poll on Oximetry Usage - pssnn - 03-25-2012
I see the cms50 for about 50 bucks online but the cheapest I can find the cms50 Plus is 90$. I actually thought the oximeters would be hundreds so I am ordering the 50D plus since it is much cheaper than I thought.
RE: Poll on Oximetry Usage - shutterbug sue - 04-27-2012
I just got my oximeter in the mail yesterday (CMS-50D) and used it for the first time last night. I ran the OxiMetry Report and was pleasantly surprised that my O2 didn't drop down any lower than 94% with a basal O2 of 97%. However the heart rate seems kind of low and I was wondering if that's normal to be so low when you're sleeping. Avg pulse was 57.6 and the low pulse was 44.
