Molecules will try to adopt the most stable conformation that minimizes strain. For cyclohexane, C 6 H 12, this would be the chair conformation. Letâs see why. If cyclohexane was planar, its structure would look like the picture to the left.
CPAP mask â There are many types of C-PAP masks. There are masks that just cover the nose (nasal cpap mask), and masks that cover just the mouth (oral masks), and of course, nasal-oral masks. There are also masks that are attached to oral appliance mouth devices.
I have slept in this position since I was a child, it is more comfortable than the fetal position. I have had sleep apnea for about a year, also restless leg. I use a biPAP machine set at 16.
