RE: Change in Pressure
@Buckeyedog, I looked at the leak graph as you advised and its very up and down. I am not sure whether this data makes more sense as a breakdown, if you would take a look for me and try and explain it I would be so appreciative. I am trying to learn all the terminology and what each item means but trying to figure out how they work together is a little baffling. I was wondering if there is a Dummy's Guide to CPAP Big Grin

Many thanks, Mirry

RE: Change in Pressure
Looking at the leak numbers, they actually look pretty good.

Your AHI doesn't look too bad. Technically you have successful therapy but most people feel better if it's a little lower. Since most of the events were Hypopneas so you may want to raise your pressure .5cmH2O and see what that does to them.

@Mirryt, it was Bama who suggested the leak info!! I'm in the learning mode same as you! I'm hoping to download my data tonight and see some numbers.

RE: Change in Pressure
Thank you Bama for taking a look. When you say raise the pressure you mean the pressure that they set at 6% correct?? He had another sleep study friday night and they want to increase it to 12%, that really concerns me such an increase, but I guess they are the experts. I am guessing that's the pressure you are referring too. I really appreciate you taking a look. Oh his Dr on the base, not his sleep Dr, suggested she order him a machine that automatically adjusts his pressure rather than a constant pressure, what do you think?

So let me get this right:

Hypopneas are episodes of overly shallow breathing or an abnormally low respiratory rate and is less severe than Apnea.

Obstructive sleep apnea is a condition in which the flow of air pauses or decreases during breathing while you are asleep because the airway has become narrowed, blocked, or floppy.

A pause in breathing is called an apnea episode, which is the obstructive sleep apnea. And a decrease in airflow during breathing is called a hypopnea episode.

So if I look at his data over the past year, much of the year shows a higher rate of Hypopneas than Obstructive Sleeps and am I right in thinking that these are the two figures that I should be paying attention to and its better that there are higher Hypopneas than Obstructive Sleeps as they are less severe, but still not good though?

@Buckeyedog, hope the download goes well and you get to see all those pretty little charts that make no sense to us newbies lol. Im so thankful that there are the experienced ones that share their knowledge, it's really challenging to get to grips with all this data.

Have a great evening

RE: Change in Pressure
Mirryt,

Welcome to the funny farm, oops, the apnea board.

The pressure numbers are in centimeters of water (cm/H2O), not %. Just so you know.

An apnea is a reduction of air flow by 90% of normal that lasts 10 seconds or more. An obstructive apnea is caused by a narrowing or blockage of the airway. A central apnea is caused by the brain not telling the body to take a breath.

A hypopnea, if I remember correctly is a reduction of air flow by 50% lasting at least 10 seconds. A hypopnea can be either obstructive or central. Hypopneas are not classified as central or obstructive by the data from the CPAP.

Best Regards,

PaytonA

RE: Change in Pressure
Yes, the pressure is the 6, but as Payton said, it's centimeters of water, not percent.

I'm sorry, but I missed the part about him having a new study and them wanting to raise his pressure to 12cmH2O.

That may seem like a lot but it's really not. I'm currently at 16cmH2O and I don't use ramp or exhalation relief.
What you might want to do is raise it to 12cmH2O and see how well he handles it. You can also set the ramp to start at his current pressure of 6cmH2O for 20 minutes or so and also you can set the C-Flex+ to 3 if he thinks he needs it.

If he does have a problem handling 12 right off, you can raise the pressure 1cm every few days until he's at the recommended pressure or until his AHI is 5 or below.

When you raise it, keep an eye on the central just to make sure he doesn't start throwing a bunch of them.
