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.
ive been using the CPAP for a little over a week now and I sleep worse with it than I do without. The mask is uncomfortable and I end up taking it of during 'sleep'. Usage is between 1.5 & 2.5 hours per night as it disturbs my sleep more than the DSA.
