I can't figure out how to copy and past yet.

Clear Airway Apnea 6 3 0 5 1
Hypopnea 0 1 1 1 2
Obstructive Apnea 4 27 13 9 15

Am I getting worse or better?

[Pugsy]

Impossible to tell what is going on because I don't know where you are getting those numbers from.

Is it AHI or total events a night number?

Work on figuring out how to get us some screen shots or give us more information about what/where you are getting these numbers.

[Abertolino]

It is on the Daily Events screen.

Day 1 CAA 6 events , OA 4 events
Day 2 CAA 3 events, H 1 event, OA 27 events
Day 3 H 1 event, OA 13 events
Day 4 CAA 5 events, H 1 event, OA 9 events
Day 5 CAA 1event, H 2 events, OA 15 events

I will keep trying to copy reports and then paste.

[Pugsy]

Ahh, those are total number of events for the entire night....Impossible to determine if bad or good because we don't know how many hours you slept to accumulate those numbers.

Need to get an hourly average to better evaluate.
If you go to the colored bars above the events tab and on the detail tab...you get AHI (which is hourly average of all the events) along with the hourly average for each event category.
AHI....hourly average for all the events (CA, OA, Hyponea)
CA index....hourly average for Clear Airway
OA index ...hourly average for Obstructive apneas
Hyponea index...hourly average for hyponeas.

Generally speaking we consider an AHI of less than 5 acceptable numbers....
but we also have to evaluate leak data to make sure leaks aren't causing a problem and maybe impacting the data.

This is a copy and paste for 2 days. Thanks for your help. Trying to understand this.

That information looks real good.
The multiple sessions point to likely waking up for some reason...turning machine off..doing something and then putting mask back on and turning machine back on.
Not unusual at all for a newbie. It takes a while to get adjusted to sleeping with the alien on our face.

With ResMed machines your leak number to avoid is 24 L/min. That is the red line in the sand where large leaks may impact therapy and/or event sensing. Short spikes into large leak territory aren't the end of the world though.
Any leaks that wake you up though...even small...need to be worked on because they wake you up and anything that disturbs your sleep is unwanted.

It is normal to have some rather large variations in your numbers when you are first starting out using the machine.
We don't sleep well...leaks are troublesome...so don't panic if you see some wide variations to start with.
Heck, I have been at it over 3 years now and sometimes I get some wild numbers and don't have a clue what may have happened.
The machine doesn't know when you are asleep or not so you may see a bit of clustering of events right when you first turn the machine on or off....so don't panic if you see those...they do get counted in the AHI though.
So if the majority of the time not much is going on and you see a cluster near a time when you were likely awake..don't worry.

With time you will understand what you are seeing. Looking my signature line for the partial SH tutorial that I have started. Main things for you to work on understanding.....AHI and the events...leak understanding..your machine reports only excess leak so any you see is above the mask's normal vent rate...and your pressure line...snore line and maybe flow limitation graph line.. The rest of the stuff...tidal volume and stuff...don't worry about it. The normals for those are extremely wide. Read the SleepyHead Glossary too...link in my signature line...it will explain in more detail.

Thanks, Pugsy. I don't shut the machine off during the night. I do get up and take the mask off to go to the rest room. I seem to be more tired since starting the CPAP then before but have read that is normal.

[Pugsy]

Okay, the breaks in therapy are when you get up for some reason but don't turn the machine off. That is okay...the machine is recording only the time that it senses breathing...so even if it is still blowing while you are away...it shows on the reports as a break in therapy because it is not sensing any breath flow.
No big deal. When you do this you may see momentary spikes in leak line...no big deal either.
