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.
If you are diagnosed with sleep apnea, your doctor may prescribe a treatment known as continuous positive airway pressure, or CPAP. With CPAP, you wear a mask over your nose while you are sleeping.

If you are taking a medication that causes drowsiness, ask your doctor about changing the medication to one that is less likely to make you sleepy.
