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.
The most common problem with CPAP is that people don't use the machine every night. Or they take off the mask during the night because it becomes uncomfortable. Even one night of not using the machine can make you sleepy the next day. If you feel like you want to stop using CPAP for any reason, talk to your doctor.
