can someone explain to me why the chart for june 14 shows 0 ahi but also shows many events?

There are two charts for June 14th (so two separate sessions). The first has the 0 AHI but is a less than 2 hour session with only flow limitations shown.

The second is an over 8 hours session, AHI 2.29.

Poster has selected one and then the other ... you can see that at the bottom of the statistics on the left.

thank you.

this has happened to me before in my early days of cpap usage; get a two hour block of 0 ahi.

reason to celebrate, i say.

Congratulations on your first night with CPAP! How did you sleep -- solidly, lots of wake-ups, or ...? Your numbers are good, and I believe you can improve them. First step: please reset your minimum to 6. If that goes well, continue to raise it gradually. What you're aiming for is a minimum that will head off most obstructive events before they have a chance to occur. At any point if you experience discomfort with a new minimum setting, back off by .5 and wait a week or two before retrying an increase.

The Oscar read-outs can't tell you what results a sleep study would have shown, because Oscar will always be showing you your treated results, rather than your untreated results. But if you can get your AHI generally below 2 -- or better still, below 1 -- the big question will be whether you start feeling better during the day than you did before CPAP. That would be indirect evidence -- though not conclusive -- that your sleep had been disrupted by sleep apnea.

Hi miss emerita

Well for the 2 hours session that i first had im not really sure if i was asleep or half asleep maybe thats why it shows 0 ahi as for the second session i woke up in the middle of it and saw the pressure was at 9. then i fell back to sleep and when i woke up the pressure was back to 6. and it was already almost 9 hours
so far the first night the only thing that i felt was different is an itchy throat , ive already set the min-max auto pressure to 6-20

for the sleep study a diagnostic center finally opened back up again in our area and they are offering an affordable portable sleep study test that i can take at home, would you recommend this kind of sleep study compared to the traditional sleep study that is conducted inside a lab? would the portable sleep study be just as accurate as the lab study? would it be a good way to diagnose sleep apnea and how severe or mild it is?

It depends on how many channels of data the home sleep study gathers as to how accurate it is going to be.

Read up on the different types.

The more channels of data collected....the more expensive the test.

Hi Pugsy

the article is really helpful as i did not know there are actually different types for the home tests too.
the one that we have here in our diagnostic center nearby costs about 180$ more or less so im guessing its just type 4 ,
would that be good enough to get a proper diagnosis?

EDIT:
here is a page from the center about their portable sleep study:
Portable Sleep Test
Contactless diagnosis of sleep apnea
Portable Sleep Test follows social distancing and is the sleep test of the “new normal” designed to detect sleep apnea. It’s a no-contact alternative to a hospital-based sleep test. It’s done at the comfort and safety of your own home without the need of a face-to-face interaction. The portable device comes in a small package that includes:

a nasal cannula to measure airflow
a belt around the lower chest to measure respiratory effort
a finger clip to measure the oxygen saturation
The portable device is brought to your place through a third-party delivery service. It’s so easy to use you won’t need an in-person assistance. However, our sleep technicians will show how to do it online. The device is cleaned according to our strict infection control protocols between uses.
Portable sleep test is also known as Home Sleep Test (HST) and Home Sleep Apnea Test (HSAT).

They should clearly state which type test it is classified as....call them up and ask them.

If you don't have any leads on the face or head....there is zero way to document actual sleep and in my mind for a test to be a sleep test they need to be able to say if you slept or not and what stage sleep you were in.

There are home studies that do document sleep stages but with just a nasal cannula, chest belt and pulse ox on the finger....no way to measure sleep.

I know a guy who was told he had about 15 apnea events at 2:30 in the morning while he was up letting the dog out to go pee...at least that's what his home sleep study said he had and he wasn't even asleep.

Im definitely gonna give them a call to clarify
but here is the website just in case you want to see : http://sleepscienzzz.ph/sleep-analytics ... leep-test/
i guess it really is just a nasal cannula , chest belt and pulse ox as seen on the picture and described on website

im glad that i asked around first before trying to get a reservation
