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.
Home Setup. 1  Place the CPAP machine on a level surface near your bed. 2  Keep the machine at least 12 inches away from anything that may block the vents (drapes, bedspreads, etc.). 3  Position the machine lower than the level of your bed so any accumulation of water will drain back toward the machine and not toward your mask.
