Tubing size
#1
Another question for "Idiot's Guide" (with me being the idiot) .... How in the heck can you confirm tubing size? I tried a Forum search and saw it had come up, but no definitive answer was given.

I just got a new Bipap autoSV Advanced machine. The tubing size pre-selected was set at "22mm." The tubing looks like all the tubing I have used with several prior machines, with tube diameter smaller than fitting diameter. I understand tube fitting size is standardized to 22mm, but that inside tubing diameter can be 22mm or the presumed newer, lighter 15mm. I thought I had been using the thinner, lighter 15mm size, but I cannot find out how to find out.

My tubing packaging is marked only with Phillips Respironics manufacturing source info and the code REF 622038. Don't even try searching the Philips Respironics website. It is totally worthless. I hesitate to cut off the fittings to measure the inside and don't have metric calipers anyway. I tried web searching numerous suppliers and while many have the 622038 listed, none specifies what the inner diameter is.

Or does the machine setting for tube diameter make any significant difference? My basic physics clamors that it has to be important. So if it is important, and setting up the machine demands an answer, why the heck is it so hard to find out?

The genuine PR 15 mm tube has a 15 molded on the end coupler.

Looking at images of REF 622038, it looks like a 22mm tube.

there is a 7mm difference, one should need a claimer caliper since that's more than 1/4 inch.

The difference between 15 mm and 22 mm is large enough to eyeball. For example, I just measured the outside diameter of my tubing by holding it in front of a ruler. I got 18 mm. Therefore given a choice between the two, the inside diameter must be 15 mm. It can't possibly be 22 mm.

Or is that just for the 15mm heated tube?

Okay. I measured circumference at 74mm, so the outer diameter should be about 23.6mm So, what does your eyeball say about the inner diameter? How thick is the wall?

I have the 15 mm heated tube for Philips Respironics. You can easily see the difference, although the connectors are 22 mm. I suspect that you have the 22 mm standard tube. There is not much thickness in the tube itself. The 15 mm tube is very flexible and more comfortable to use. I'm not going to grab the micrometer tonight, but I would guess the outer tube diameter is not more than 17 mm.
