% of time in SpO2 Drop ? - kasiahbug - 06-30-2018

What does % of time in SpO2 Drop actually mean?
I am using SleepyHead and confused by that number - 
It says that there were 450 events - 

Average SpO2 % 96.08
Min SpO2 % 61.00
SpO2 Drop Index 46.78
% of time in SpO2 Drop 48.84%

According to the software that came with the oximeter it showed only 12 events <88% and only 2.8 minutes <88%
I am trying to figure out if we should be using oxygen with his machine at night or not??? 

Also, I'm going to put his "card" in and read it later for the first time, any tips on how to get the most of the information?

Probably Sleepyhead and the software that came with it are set to different reporting points. You can go to Sleepyhead's files under preferences, than oximetry. You can adjust the O2 % used to report a drop and match it to the software your using. normally 4% is what is considered a drop in O2 levels. Regardless of the drop if it's above 90% you should be OK.

Thanks .. I'll check the preferences <3

Min SpO2 % 61.00  is bad

Yes, unfortunately it happens a lot - BUT it doesn't stay down for long. He does O2 supplementation during the day because of that as well.

Two minutes isn't terrible.  However, our bodies recover slowly from low oxygen saturation and so many drops lasting only seconds could be more damaging than only a few of longer duration.  (Does this make sense?)

Since your "he" is already on oxygen during the day, if he's using an oxygen concentrator, it makes sense to feed it into the PAP at night.  OTOH, if you're using bottled O₂, you should investigate to determine if it's necessary.  (Hope that helps!)

PS: I'm the opposite: O₂ sat is find days but fluctuates (badly) while sleeping (over 100 minutes below 70%); Bi-Level PAP didn't overcome it and I had to go on supplementary O₂.  It's curious that your "he" needs O₂ days but seems to skate while asleep.   Thinking-about

"he" is my 10 year old son :Smile
His oxygen drops a lot and at night a lot - but also some nights and some days never. The longest it's dropped is 10 minutes but usually it's just a couple minutes at most or seconds. His heart rate and blood pressure also flex so much, too. He has autonomic dysfunction. Completely random and for no reason. He was having amnesia, so we believed it due to O2 drops?

Oh, that makes me sad.  It must be even more difficult that it is so irregular.  As you know, O₂ deprivation does cause numerous mental problems; cognitive and memory problems, attention, and even emotional problems.  Fortunately our bodies do recover, though recovery is slower than the effect – and I'm sure there is a possibility of permanent damage if the condition is long or deep.  It is great that you have determined the treatment he needs and can address it.
