Avocet8 or other exp'd person please answer
I got a Dr Joel pump Tuesday (locally) and it came with 2 1/4” for main unit & 3 1/2 for main unit and sac but anyway I think thats kinda of big for me 6 1/4 x 5 enbp so today I went to get 1 3/4
(because of what you have said as well as size charts) but I could not find one anywhere so I got 2” from Boston pump. I used Wednesday it didn’t feel to big, no air leaks, but I had space every where but at very bottom. My head was close but not touching, I have a big head anyway. I only went 10 minutes @ appx 3 inHG to be safe. **QUESTIONS ARE **
1) Are all cylinders a little different in size anyway?
>
2) If you use one that is 1/4 too big but it seals fine, but has more
room than what you need is that when deformities happen?
>
3) What would you do if $$$ is tight, keep the 2 ” or order the right one 1 3/4 ?
>
4) Appx how long do you stay in one tube if you are a newbie?
