Leak rates? numbers machine itself vs. the card reader

Mr. Sleep wrote:I am a newbie on the cpap. I am clear that Total Leak = Intended Leak (by mask manufacturer) + Unintended Leak. My problem is that my Total Leak is 14 l/m and the Intended Leak is 28 l/m. That would yield a negative Unintended Leak.

Does that suggest a defect with the mask? Should I worry about rebreathing (CO2 levels)?

I have a Remstar Pro m-series at 8cm pressure, and a Swift LT.

Hi, Mr. Sleep, and welcome to the forum.

Suggestion 1: Please fill out your profile (User Control Panel, top left) and list the equipment you're using (choose TEXT, please), and include any details about your therapy or diagnosis in the Comments section. All of that pertinent info will be included at the bottom of your posts, which will help us to give you tailored advice whenever you have a question.

Suggestion 2: Start a new thread ("Post A New Topic") with "Leak Rate Too Low" or something similar in the title, to get the attention of the more experienced members on the forum. You'll find lots more help that way, as your question is buried in this thread of different subject matter and will likely go unnoticed by many.

Personally, I have no idea why you'd be getting a reported leak rate that's half of what it should be. The only explanation I've seen here for lower-than-normal leak rates is the possibility that the exhaust (vent) holes on the mask were blocked (by a pillow or blankets, for instance). Sorry I can't offer you more of a concrete answer, but if you start your own thread, you'll get more help.

Nope, not unusual at all. It's something to look forward to when you know the therapy is working.

Ditto. It's a good thing we have this forum, where others understand us so well and don't give us the when we sound so nutty.

Well I just had busy day. will be soooo glad to see a mask and a pillow soon.

We had both our kids and familys, in-laws too. For my hubbys 53rd. It Was fun.

The good news...my son took home a couple of my extra masks to try, while waiting on the new mask he is getting. Boy, did he look like he really needs a good nights sleep.

Funny thing, he did not want his 4 yr. old to see it on his face...might scare her.

She thought it was funny. And loved playing with my yukky old (new) chin strap. Doesn't take much to make a 4 yr old happy. Her daddy forgets she has a mask for Bronchitus, so she is familiar with them.
She is such a blast.

well that should be all for today. I am going to try the full face I used last night.

have a good sleep
