Tubing diameter dilemma

[Lyndmc]

After getting my new Airsense 11, I was given the heated tubing. I could not get enough air thru that tubing and I woke with sore lungs. I replaced the heated tubing with the non heated tubing from my Airsense 10 and slept well. That tubing was purchased from CPAP.com and it is 7/8” diameter. Now on Medicare, my supplier sent me 1/2” diameter slimline tubing. I’ve got the same issue as with the heated tubing, I wake up with sore lungs from laboring to inhale.

Is there such thing as a standard tubing that is 7/8” OD with Slimline tubing being 1/2” OD? I think the volume of my inhale is being limited by the smaller diameter tubing.

My CPAP supplier only carries the Slimline 15mm CPAP tubing, I had to buy more own 19mm tubing.
I didn't have the breathing issue you had. Good luck

You made a previous comment (viewtopic.php?f=1&t=185930&p=1460395&_g ... .#p1460395) in which you were advised to correctly set the configuration of your hose with the device. You never responded. Set it correctly, and you won't have a problem with the slimline hose.

Sorry, I must have missed your post. My machine is currently set on standard, I must never have seen that setting. Tonight I’ll try the slimline tubing on the slimline setting.

Thanks for this. I did find that my usable tubing is 19 mm rather than 16 mm slimline. So is it safe to say that the slimline setting just increases the pressure? I ask because I have tried to raise the setting above my normal setpoint in the past and it didn’t work. It’s been my assumption that the ID volume of the slimline was the problem and I couldn’t get the flow, but maybe this is incorrect.

Update: I connected the slimline tubing and set my Airsense 11 for slimline. I was able to go to sleep, but I woke at 3:30 am and had to swap the tubing to standard. Once I swapped the tubing to the 19 mm and changed the setting to standard, I went right back to sleep and slept well.

The slimline tubing was kinda ok for me to be able to go to sleep, but I woke up in the middle of the night uncomfortable. In conclusion, I’ve got to stick with the 19 mm standard tubing if I want a good night sleep.

One night does not make a trend.
