Anyone have a link for me to decipher my graph?

[Patsyw]

Don`t know whether anyone can help with these study results. It took place from 23.09 to 7.00am but looks like I didn`t fall asleep until 23.30. It shows:-

Snore - 291.3

Flow - 42.3

Sp02 Events - 40.9

Sp02 - no total but the waves sometimes dip below 90

Cardiac events - 169.6

HR - no total but the waves range from below 50 to about 150/200

Clas.PTT - 34.6

If anyone can throw any light on these results, I`d be grateful.

It means you snore a lot and have mild OSA.

I've no idea about Clas.PTT but please Google it and let us know.

I think this curve was your sleep study but I don'y know if it was with or without CPAP. If with CPAP, your pressure is way too low.

I wouldn't worry too much about data gathering for now. The essentials you need to know are your set pressures and your AHI.

I have googled loads but cannot find any graphs to compare or what Clas.PPP means. Never mind - I`ll ask them to explain it again when I go to the hospital next time.

the SPO2 reading is blood oxygen (Saturation of Peripheral Oxygen) - normally this sits around 98 - 100, but drops if you hold your breath. Dips to 96 are not unusual and wouldn't disturb you, but bigger dips (partuculary ones to below 90) are an indicator of Apnoeas. The dips are not a diagnosis in themselves, just an indicator that something is hapenning to drop the blood oxygen level.

The SPO2 events - this is the number of times during the study that the SPo2 level dropped below a particular level.

Thank you Fredxx - that`s very helpful

Hi Patsyw

Here's what your charts will look like after you are successfully on CPAP





Lots of straight lines in SpO2, no large variations, pulse fairly stable, no large variations.

Last night I had six events in 6.5 hours, giving an index of 1. An SpO2 event is not the same as an AHI event but we want below 5 in both so you can kinda regard them as the same in that if they go above 5, you need to adjust your CPAP settings.

When we have an apnoea, stop breathing, oxygen levels dip, survival kicks in and heart races trying to get oxygen to our brains. What we want to achieve with CPAP is steady oxygen saturation levels, as near as we individually can to 99%. I smoked till twenty years ago and get 95 - 96% as normal.

So nothing like the graph on my avatar then!

[Tigers Fan]

I think your avatar is in deep doody!

I think your avatar is in deep doody!

Actually it was just four pints of India Pale Ale (IPA), but from here on I shall always refer to it as "Deep Doody" and stick to halves.
Joking aside, I am very glad I invested in an oximeter as that particular five minute episode shown in my avatar underlined that just because you have years of experience with CPAP it doesn't mean you can drink and eat whatever without possible consequences, it is not just about getting the optimum fitting mask and your CPAP settings just right.
