Read the article this morning. It is about measuring air flow and the various techniques to do it. Also, about older technologies that shouldn't be used. The article was published in 2001 and the newer and better techniques are already implemented in our equipment. It doesn't have anything relevant ...

Good idea. I didn't think of that. Will do.

JDS74 thank you for the article referral. Even if it doesn't answer my question it seems to be a good article for my collection of sleep articles.

JDS74, I think your explanation is correct.

The tubing was bent at a sharp angle to accommodate a tight spacing and this is probably what separated it.

Thanks.

There is a difference between accuracy and precision.

Since this is a relative change the question isn't the accuracy, but the precision of the tool.

It was the tubing that came with the nasal pillows for my S9 Elite Resmed.

It was sold by American Home Patient. It was given to me when I picked up the machine.

I checked my file folder and I don't see any information on the hose, just the CPAP machine. Sorry.

I am looking for articles on nasal air flow restrictions and CPAP therapy. I have been looking but not finding published articles. This is my analysis. dP = delta Pressure F = flow R = equals resistance in a channel to flow. The basic equation is dP = F*R This is not strictly true since dP goes up a...

This may be well known to many of you, but just for those you might not be aware and for people doing google searches. The tube connecting your face mask or nasal pillows to the CPAP machine typically has some outer rings in it to keep it open. However, depending on the design the air may be conduct...

So Palerider, would you characterize your response here as cyberstalking or cyber bullying or both.

I thought this group had a moderator.

The web page states that it isn't a medical device. In looking over a sample of the journal articles I only see abstracts and not the actual article. The articles state that the S+ is able to pick up some motions as well as a wrist attachment. Yes they are equal, but is either one of them of great u...

1. See if your unit can support an oximeter attachment. Then you can get your SpO2 performance every night. 2. It does cost a little over $1500. It is pricey. I have found it to be invaluable during this last summer when I steadily increased my pressure and found that between 12 cm-H2O and 15 cm-H2O...

My inquiry is about head colds and oximeter statistics. I see my median SpO2 has dropped to 93. I had been fairly consistent at 94. I have had a head cold. I am interested in more definitive answers rather than speculations. The fact that I am congested might mean O2 transport to the blood would be ...

Your experience is not uncommon. The practice of sleep medicine is shoddy. I got poor treatment and a brick like you. This is all too common for apnea treatment. The sleep centers often don't follow any written protocol either. The following has information that you might find useful. I also suggest...

This is a very informative result. I wonder how many other people have seen their AHI change because of nasal pillows?

I have not responded in a snarky way. I did criticize your comments to my post analyzing them and quoting you.

That happens in life. Somewhat makes assertions that deserve criticism and then they get criticism.
