Hi Cpap, I haven't used this trick myself by have read about it from folks that use multipl;e 100's and have a tough time with adhesion. If you clean the area like your normally would, the trick is to spray one of the steroidal sprays like caldacort or one of the steroidal nose sprays on the area prior to applying the patch, the spray leaves a slight tackiness that helps with adhesion but doesn't prevent absorption, maybe that's what the tegaderm is, but it's worth a try as I've met dozens of folks over the years the use this method along with extra tape and the dressings. Also having someone else apply them so you do have to twist or lift your arm up so you can see what your doing, as soon as you drop your arm dback down you start of with a crease, that was something I noticed when I gave duragesic a shot.

Adhesion is a common problem so try anything and everything that works for others, It's not going to get cooler or less humid in the summer so you pretty much need to find a resolution now before the things start sliding off in a matter of hours when it's 95 degrees and 95% huidity.

Good luck, Dave
